Nebulizing Hydrogen Peroxide for Respiratory Health
Hydrogen peroxide is an antiseptic agent that is used to fight pathogens. Increasing evidence suggests that it may be beneficial for your respiratory health when nebulized. Nebulizing changes medications or other therapeutic agents from liquid to mist. Inhaling hydrogen peroxide through a nebulizer may help you improve your respiratory system and regain your health quicker if you are feeling unwell.
In this article, you will learn what nebulizing is. You will learn what hydrogen peroxide is and its uses. I will discuss how functional medicine doctors are using nebulized hydrogen peroxide. You will learn about the benefits of nebulizing hydrogen peroxide.
I will discuss several scientific studies on the benefits of nebulizing hydrogen peroxide. You will learn the steps of how to use nebulized hydrogen peroxide. I will also share some additional options for nebulizing, including the Brownstein protocol, nebulizing silver, and nebulizing glutathione.
What is Nebulizing?
A nebulizer is a piece of medical equipment that changes certain medications or therapeutic supplements from a liquid form to a mist, allowing you to inhale it into your lungs. Nebulizing helps to quickly administer the medication or supplement directly into your lungs. Nebulizers have a mouthpiece or face mask to put over your face to inhale the mist through it. The therapeutic agent then goes straight into your respiratory system and lungs—exactly where you need it to take effect.
Nebulizers are often recommended for people with asthma or other respiratory issues. They may be used for acute respiratory infections. As you will learn from this article, nebulizing with hydrogen peroxide is a safe way to naturally support your health if you have a respiratory infection.
Nebulizers are highly affordable. Home nebulizers start at around $50. They are typically large and must be plugged into an electrical outlet. Portable nebulizers are slightly more expensive, but because they are small and battery-powered, they are an excellent option for folks with a busy lifestyle.
What is Hydrogen Peroxide?
Hydrogen peroxide (H2O2) is a mild antiseptic agent that is made up of two hydrogen atoms and two oxygen atoms. Hydrogen peroxide releases oxygen when applied to affected areas, which causes foaming action. This is because the blood and most living cells contain the enzyme catalase, which attacks hydrogen peroxide and converts it into water (H20) and oxygen (O2).
The oxygen free radicals have a negative charge that interacts with pathogens and damages their cell walls. This helps to destroy bacteria, clean areas, and remove dead skin cells. Your white blood cells make and use hydrogen peroxide to fight bacteria, viruses, fungi, and other pathogens.
Hydrogen peroxide has long been used as an accepted, safe, and affordable disinfectant for surfaces, cuts, scrapes, burns, and minor wounds. It may also be beneficial as a mouth rinse that helps to relieve canker sores, gingivitis, and other minor mouth irritations, and reduce mucus. Furthermore, hydrogen peroxide may be beneficial for your sinus-, lung-, and overall respiratory health.
It turns out that the friendly bacteria in the mucous membranes of your lungs, sinuses, nose, mouth, digestive system, and urinary tract thrive in environments that are rich in oxygen. Hydrogen peroxide is very high in oxygen which may help these friendly bacteria thrive but harmful pathogens to die.
Hidden Epidemic, a book by Dr. Thomas Levy published by MedFox Publishing in 2017, discusses the role of hydrogen peroxide in acute viral respiratory infections (1). Following the infection, your oral and nasal cavities stay in a low-grade infectious state with a biofilm of disease-causing colonies of viruses.
As a result, they may persist chronically in your oral cavity, such as your tonsils. As pathogens get swallowed, the ongoing infection may also compromise the health of your gut, teeth, and gums. This may lead to ongoing oxidative stress in your gut and leaky gut syndrome. Dr. Levy argues that nebulizing hydrogen may be a way to tackle these infections.
Doctors Using Nebulized Hydrogen Peroxide
As prescription medications became more popular, the interest in the benefit of hydrogen peroxide declined in the 1940s. However, recently, there has been increased attention to hydrogen peroxide and nebulizing with hydrogen peroxide. Many functional medicine doctors, including Dr. Levy and Dr. Mercola, have been recommending nebulizing hydrogen peroxide.
Dr. Mercola recommends starting nebulizing with hydrogen peroxide the same day as you notice a respiratory infection coming on (2). He believes that nebulizing with hydrogen peroxide can be an effective mono treatment. However, adding vitamin D, zinc, and quercetin may be highly beneficial.
Nebulizing H202 loses its effectiveness as the respiratory infection gets worse so it is important to focus early on and do it for 5–15 minutes at a time every waking hour. After you feel better, you can do it every 4–6 hours until you feel close to 100%. The goal is to stop the virus before it gets deep in the lungs where it causes severe inflammation and can progress to serious illness.
Dr. Levy has written extensively, including in his book, about nebulizing hydrogen peroxide for respiratory issues (3). He explains that nebulizing hydrogen peroxide may help to break down and inactivate viruses. He recommends daily treatments several times a day until a few days after you feel completely normal. He believes that nebulizing hydrogen peroxide may also be a great preventative strategy.
Dr. David Brownstein also recommends nebulizing with hydrogen peroxide in a scientific article published by the Institute for Pure and Applied Knowledge (IPAK), Public Health Policy Inititiative (PHPI) in 2020 (4). According to this observational case series, nebulizing a hydrogen peroxide/saline mix with Lugol’s iodine seemed effective for respiratory infections. In this case series, patients received individualized treatment, and some were treated with intravenous hydrogen peroxide, vitamin C solutions, and/or intramuscular ozone.
Health Benefits of Nebulized Hydrogen Peroxide
Nebulizing hydrogen peroxide may offer a number of health benefits, including respiratory, oral, and digestive health.
Improved Respiratory Health
One of the main benefits of nebulizing hydrogen peroxides is improved respiratory health. A 1996 study published in Respiratory Medicine found that nebulizing may be an effective therapy for respiratory and lung health (5). A 2020 review published in Medical Hypothesis found that hydrogen peroxide may be beneficial for viral infections (6).
Reduced Oral Pathogens
Nebulizing hydrogen peroxide may also help to reduce oral pathogens. A 1995 review published in the Journal of Periodontology found that hydrogen peroxide may help to reduce plaque and gingivitis (7). A 2016 study published in the Journal of International Society of Preventative and Community Dentistry found that hydrogen peroxide may help to reduce gingivitis in periodontist patients (8).
Improved Digestive Health
Hydrogen peroxide may also benefit your digestive health. A 2017 study published in Gut Microbes found that hydrogen peroxide may help to control pathogens in the intestinal mucosa (9). A 2020 study published in Cell Host & Microbe also found that hydrogen peroxide may help to reduce the microbial load in the gut (10).
Studies on Nebulized Hydrogen Peroxide
There have been a number of recent studies on the potential benefits of nebulized hydrogen peroxide. A 2016 study published in Food and Environmental Virology found that nebulizing hydrogen peroxide may be beneficial for various respiratory infections (11). A 2020 review published in Medical Hypothesis found that hydrogen peroxide may be helpful for viral infections (6).
According to a 2020 article published in Infection Control and Hospital Epidemiology said that using nebulized hydrogen peroxide may help to reduce the hospitalization rate related to respiratory infections (12). A 2021 case series published in Evidence-Based Complementary and Alternative Medicine found that nebulizing with hydrogen peroxide may be a beneficial option for respiratory infections (13).
How to Use Nebulized Hydrogen Peroxide
To get started with nebulizing with hydrogen peroxide, I recommend this Desktop Nebulizer. It’s important that you always use food-grade hydrogen peroxide. I recommend this Essential Oxygen Food Grade Natual Hydrogen Peroxide.
I recommend you make your own saline solution using the following instructions. You may also choose to purchase a quality saline solution, such as Modudose Saline Solution for Inhalation, but remember these come in 5mL so you need 47 doses to make it equal to 8 oz. It comes in 100 per box.
How to Make Saline Solution
- Fill up a 8 oz. glass jar with purified water. It’s important that you don’t use tap water but purified water only.
- Add 1/2 teaspoon of Himalayan Salt, Celtic Salt, or Real Salt.
- Stir to dissolve.
How to Prepare Hydrogen Peroxide for Nebulizing
- Add 2 teaspoons of 3% food-grade hydrogen peroxide to the 8 oz. saline water you just prepared or 8 oz. of Modudose Saline Solution for Inhalation. However, if you are starting with 12% hydrogen peroxide, add 1/2 tsp to 8 oz. of saline water
- Transfer this mix to a glass dropper bottle.
- You can keep this solution refrigerated for a long time, so I recommend labeling your bottle or jar.
How to Set Up Your Nebulizer
- I recommend reading the instructions of your nebulizer carefully.
- Connect the tubing to the nebulizer.
- Open the nebulizer medicine container and add 5 mL which is 3-4 droppers full or about 1 teaspoon of your hydrogen peroxide and saline solution.
- Put the mask on and breathe in the nebulized hydrogen peroxide solution.
Start nebulizing with hydrogen peroxide as soon as you start feeling unwell. Use it for 5 to 15 minutes every hour until you start feeling better. You may likely feel better within the first day. Once you are better, reduce nebulizing to every four to six hours until a few days after you are completely well.
Besides nebulizing hydrogen peroxide, there are other substances that you may try nebulizing with to support your respiratory health naturally. I recommend the Brownstein protocol, nebulizing silver, and nebulizing glutathione.
You may benefit from the Brownstein Protocol by Dr. David Brownstein for respiratory health. Dr. David Brownstein also recommends nebulizing with hydrogen peroxide in a scientific article published (4).
In an observational case series by the Institute for Pure and Applied Knowledge (IPAK), Public Health Policy Inititiative (PHPI) in 2020, Dr. Brownstein and his team found that nebulizing a hydrogen peroxide/saline mix with 2 drops of 2% Lugol’s iodine. If you feel fine with that you can increase your dosage to 5–6 drops of the iodine. You do this each time you nebulize.
The Lugol’s has potassium iodine and I personally recommend using a pure nascent iodine instead. So I prefer doing 3–6 drops of a nascent iodine such as Detoxadine Iodine to your hydrogen peroxide solution.
You may also benefit from nebulizing colloidal or nano silver for respiratory issues. A 2008 study published in the Journal of Royal Society of Medicine found that colloidal silver may be beneficial for lung health (14). A 2021 animal study published in the Journal of Equine Veterinary Science found that colloidal silver may be helpful for respiratory bacterial infections (15).
Follow these directions for nebulizing with colloidal silver:
- Fill the medicine cup of your nebulizer with a non-diluted nanosilver up to the 2 ml mark. I recommend using Silver Spray for nano silver. Avoid using homemade silver as the particles are too large.
- Following the directions of your nebulizer, turn it on, put the mask on, and inhale deeply. Hold it in for a second, then exhale.
- If you have an acute infection, I recommend 6 to 7 minutes 3 to 5 times a day. Use it for about 6 to 7 minutes each session once or twice a day for prevention. If you are using it for lung regeneration, start it with one time a day.
You may also benefit from nebulizing with glutathione for respiratory health. Glutathione is an antioxidant that can help to reduce cellular damage. A 2000 case report published in Alternative Medicine Reviews found that nebulizing glutathione may be helpful for emphysema (16). A 2005 study published in Free Radical Biology & Medicine found that nebulizing glutathione may be beneficial for lung health (17).
A 2008 study published in Evidence-Based Complementary and Alternative Medicine found that nebulized or aerosolized glutathione can benefit respiratory and lung problems (18). A 2015 study published in the Journal of Cystic Fibrosis found that nebulized glutathione may be beneficial for lung health (19). Glutathione can be especially good for helping to improve chronic lung diseases.
Follow these directions for nebulizing with glutathione:
- Set up your nebulizer according to the directions.
- I recommend using Reduced L-Glutathione Plus for nebulizing.
- Break 1 capsule of glutathione open. Pour the content of the capsule into the medicine cup of your nebulizer. Add about 1 teaspoon or 5 ml of saline solution or pure distilled water. Let it sit for a bit until the solution looks perfectly clear.
- Once ready, put the mouthpiece on and begin inhaling. The treatment of 1 capsule lasts for about 4 minutes.
Hydrogen peroxide is an antiseptic agent that may be beneficial for your respiratory health when nebulized. I recommend following my tips for nebulizing hydrogen peroxide to improve your respiratory system and regain your health quicker if you are feeling unwell.

Thank you SO VERY MUCH! Finally, an article that explains the directions in plain English….and not just % this and % that, which is hard to understand!! All your articles are so complete that there is no doubt what is being said. Thanks again.
Glad this was so helpful!
Is this method better than using Brown’s gas? HHO? Thank you
Yes it is!
Thank you for all you do. Can you help recommend any Dual Voltage 120V/240V nebulizer as I have not found one on Amazon or anywhere else yet? If I must go another route, are there battery operated ones for travel that would meet desktop effectiveness standards? I hesitated asking you, but I looked many hours and have not found anything in stock meeting those requirements. Many blessings!
Thanks great analysis..my whole family has been nebulizing h2o2 for a while now but always found it irritates the throat..it is most likely the sailine solution, is there a solution to this problem. Tnks
The seller and maker of blubonic H2O2on Amazon says:
“Only distilled water can be used to dilute. Any other type including purified water contains trace amounts of metal and metal ions which will turn the hydrogen peroxide back into water and oxygen.”
~ By Blubonic Industres on February 7, 2019
These metal ions act as catalysts and speed the reaction to produce O2 and H2O.
Saline has Na+ and Cl- in it, the Na+ will be a problem. The Cl- may be as well.
I use distilled for my family, and food grade peroxide.
This is exactly what I’ve been looking for apropos the use of hydrogen peroxide in relation to common or uncommon ailments that, at present, are wrecking the lives of millions of people. As someone said earlier, your articles are complete and leave no doubt about what needs to be done next. Many thanks from a prisoner at Avalon whose journalistic colleagues wouldn’t know sensible advice from a mosquito wearing a spangled face mask.
So glad to hear this has been helpful for you!
Can you nebulize hydrogen peroxide with colloidal silver together? If so how much if each. Is nebulize with distilled water okay?
Yes you can but we always recommend using saline rather than simply distilled. Very easy to make your own saline solution.
No, it’s actually very dangerous to use just distilled. Mercola says it in his video.
When nebulizing H2O2, you should not use a titrated 3% pharmacy grade due to its stabilizers, (acetanilide or similar organic materials).
You should be using a 35% food grade product and then titrate it down to Dr. Brownstein’s recommendations.
I have a 3 year old that swallowed fecal matter in the womb he was in intensive care with a lung infection at Birth ever since then that baby is only well one week out of every month I need help I’ve heard that using a Nebulizer with cs is good but how about the hydrogen peroxide how much and what stenghth
Tks for the info. Did you mean to say ok to use 3% Food vs “35%” Food grade? I know not to use titrated pharmacy grade but I have 3% food grade (that I understand needs to be diluted for nebulizing). Thanks for your time.
This was a great article!
So much to use the 3% or 12% FOOD GRADE hydrogen peroxide. The 35% is very strong and much more difficult to dilute.
Love your explanation! This is why I come to your site!
Thank you Angela!
Thank you for this comprehensive article on nebulizing. This will be my go to for reference. I can not help but think how many lives would have been saved these past two years.
Yes absolutely and thank you for your support!
Happy Solstice! Are there any contraindications for this nebulized hydrogen peroxide treatment? Thanks for the how-to guide, I so very much appreciate it! It will make a great Christmas present to everyone on my list! Many blessings!
None that we are currently aware of at this time.
I have heard that it is not good for DOWN SYNDROME folks. Is this true?
I haven’t heard or seen anything about that.
Can you just put hydrogen peroxide in water and bring it to a steam and breath it in?
Yes you can do this, although it is not as powerful as nebulizing it.
Can I use some Hydrogen peroxide in a diffuser at night by my bed.
Sure you can! But it won’t be as powerful as nebulizing it.
Thank you for responding. I appreciate all your articles. Thank you Dr Jockers and staff.
Thank you – great info!
FYI – I have my EO diffuser in the kitchen on the counter, near my propane gas stovetop – never had a problem w/ EO but when I diffused the H2O2 solution as directed, it turned all the normally blue flames on all burners bright yellow-orange…so, it maybe more effective in a diffuser than expected. Needless to say, I have moved my diffuser to a new spot. This treatment has been helpful regarding my health issues.
Yes I have mild COPD. I use regular medicine in my nebulizer when I need to use it. I also have a portable nebulizer that takes batteries and I can take it anywhere I go if needed. Now, my question is I put the peroxide the iodine and Celine solution in my nebulizer right? What about the silver stuff? Do I put that in with all this other stuff as well? And what about vitamin C and D? Can I put that in there as well in the mix? Many thanks.
Yes adding some Silver can be very helpful as well. You wouldn’t nebulize vitamin D as that is a fat soluble nutrient that needs to be consumed from the sun or in food/supplements orally.
Thank you Dr Jokers for this very comprehensive info on Peroxide Nebulizing, With my Naturopathic Dr I have have had Peroxide IV s also the Vit C I Vs , Also have Nebulizer ALA (Alpha Lipoic Acid) and DCA. Reasons are to do with Cancer. I do have the 35% food grade Peroxide in my fridge, so I feel prepared since reading your info here, I will have a trial doing this tomorrow.
Thanks again, I always follow you on here.
Thank you for sharing! Blessings!
Is water through a Berkey filter the same as purified water to make the saline solution?
Yes that would be filtered water which would work.
Is it possible to add some peroxide in a nasal rinse bottle instead of using a nebulizer?
You can do this for a nasal rinse but it won’t get into the lungs and help reduce the microbial load in the lungs.
So when making a colloidal silver solution for the nebulizer you don’t need to add a saline solution? You just use colloidal silver all by itself?
I just want to make sure. Thanks.
Yes that is correct, if it is a colloidal or ideally a nanosilver base, you can use that by itself.
I’m a functional medicine practitioner and just want to say how much I enjoy your articles. Although I know most of the stuff I read herein, sometimes an article brings up something I haven’t heard of, or causes me to have another look at a topic I haven’t visited in a while.
I’m wondering if this peroxide protocol could be used in a humidifier for a home or office so everyone may benefit, but thinking the peroxide may break down with that use since it is so unstable. Have you read anything about using it in a larger area than just nebulizer. Thanks so much!
Yes the peroxide dosn’t hold up very well in the humidifier. I prefer using essential oils such as tea tree oil, peppermint, lavendar, etc. for this purpose.
The nebulizer you recommend has the worst product reviews on Amazon. I bought it myself too, and the instructions are very poorly written. It states that we need to get replacement filters every 6 months but these seem impossible to get. They state that the “nebulizer kit” (whatever that is) is “for single use only”.
Just FYI. Otherwise I’m grateful for this article.
Thanks for the feedback. I don’t think you need replacement filters as I have had mine for a while and it works well. However, we will look into other brands such as this one: https://amzn.to/3eY2c8h
What about the single use only? I was wondering that too… can you reuse the kit? Seems outrageously expensive doing it every hour and having to use a new kit each time.
No, just wash it out and you can reuse it indefinitely.
The nebulizer referred to in the above link is no longer in stock. Any other suggestions?
This one here Annie: https://amzn.to/3si8PIv
Dr. Mercola recommended this nebulizer in 2020 and I’ve been nebulizing HP, CS and Lugol’s iodine using it since then. It’s fabulous, sturdy, powerful and no-maintenance. The separate battery pack isn’t needed if you plug it in to an outlet as I do. It’s small enough to travel with and I never leave home for more than a few days without it. I recommend this one to everyone along with the HP protocol using the same food grade HP you recommend. Glad to see you confirming what I learned from Dr. Mercola and Dr. Brownstein and used to minimize Covid effects the last 2-3 years, the protocol is the bomb. So are your informative articles…the best!
I worked as a respiratory nurse for several years in a home care setting. My client had nebulized treatments X4 a day. Although the mask & nebulizer cup may say single use, they can be used for as long as you feel comfortable to use them. For myself, I wash my neb cup and mask after each/any use and let air dry. Regular dishsoap is adequate, but if ill you may want to put a bit of white vinegar in the wash water as well. Most filters can be removed and lightly washed and air dried. Very simple. It filters air, so be sure it is dry before returning it to the machine. The ‘single use’ reference is mostly targeted for a hospital setting where they should be disposed of with each use, not home use. I hope this was helpful.
Thanks for sharing this great info Mikel!
How and where can I order a nebulizer as shown???
You can get this here Jana: https://amzn.to/3eY2c8h
I would like to know where the machine you are recommending is made. I cannot find that info or info about how easy or not it is to clean it Also, if no replacement filters are available, it iseems a bad deal. Hope you reply to my email. Thank you!
Hello Bruna, here is another option with good reviews: https://amzn.to/3eY2c8h
Very Interesting and comprehensive!
I’ve just been studying about Molecular Hydrogen and Hydrogen-Oxygen Inhalation Therapy and have bought a hydrogen water bottle for drinking and inhalation (Osmio/UK). I do wonder how Hydrogen Peroxide compares? I’ve got a portable Nebulizer that I’ve been using with colloidal silver.
Yes hydrogen peroxide is different. It is the free oxygen radical interacting with the pathogen that is key here as opposed to the molecular hydrogen increasing antioxidant potential in the body.
will doing red light therapy before wich causes nitrate oxide and ros be dangerous to use before? or synergistic?
A study say nitrate oxide + hydrogen peroxide creates a super oxidizer. so will this be dangerous … or good? hmm
No this formation of ONOO- or peroxinitrate happens within the cell as a normal part of metabolism. Red light therapy increases endothelial nitric oxide but reduces ROS so it will help reduce peroxinitrate formation.
Thank you for the article. It explains clearly the benefits of nebulizing H2O2 and how to do it. I do think your dilution instructions may be mislabeled as you are diluting to .1% (Dr. Mercola’s recommended amount) but the chart is labeled “Proper Dilution for 1%….”. Also Dr. Levy recommends a much higher dilution for faster results. Please clarify as I want to share article with friends.
I just followed your instructions to the letter. Using 1/2 tsp of the saline/peroxide solution in the nebulizer cup gave me about 1 minutes worth of nebulizing treatment. This seems way too short considering your article says you should do this for 5 to 15 minutes.
Try making more as your nebulizer seems like it dissolves the fluid and pushes it out quickly.
Tricia, If you make up 8oz of the Normal Saline per the instruction, then add the amount of recommended food grade Hydrogen Peroxide, put it in a good jar & labeled in your refrigerator. Then, when you want to nebulize with it, use a med cup or syringe to draw up 5-7 mls of the solution .. squirt in to your nebulizer cup and you are good to go. The teaspoon measurements I think were for making the solution. Most neb cups will have measurement increments marked on the outside of the cup. I usually use about 7 mls. If you don’t have any syringes, ask for one from your pharmacy or veterinary. Syringes make it a lot easier, or a med cup that has measurements on it. I hope this was helpful
I realized I made a mistake and nebulized hydrogen at too high of a concentration 3 days ago. I did 1/2 3% food grade hydrogen Peroxide to 1/2 saline solution. I nebulized a total of 4ml of this solution.
My breathing became worse and I have had some other strange and intense side effects come up since I nebulized this solution- hot flashes, tingling in extremities, acid reflux- particularly when laying down, chest pain, and burning in rectum after going to bathroom.
Am I at any risk for long term damage? Any suggestions to help these side effects?
Hello AG, sorry to hear this! No you should recover just fine within a week.
Re: incorrect ratio
I almost did this too! I first saw this on social media and while doing my own research, I found this website. I am grateful that i noticed the ratio here because it says 1% on some of the videos! Not .1%! I have copd. Like really bad. Asthma, pneumonia prone, etc. Anyway, I am thinking I want to try this 🙂
A good rule of thumb is to include the zero ( 0) before writing .1 % so that the chance of an inaccuracy is reduced. SO… here is how to best write this– 0.1%
Thank you for the nebulizing instructions. I have read instructions elsewhere, but your instructions are the most complete. I have all the needed supplies. Now I feel prepared if I should get Covid. Many thanks!!!
Is this safe to use during pregnancy?
Yes it is!
Are you mad!! As a cleaning agent for cuts etc I can go for. Even orally where one is not swallowing and spitting out I can understand but into internal organs. May god forgive you for peddling such tripe. You’ve even included testing on horses….unbelievable ⚠️
You most certainly can swallow food-grade hydrogen peroxide! It is TOTALLY SAFE!
You can even feel the difference in your stomach after swallowing it. I’ve done several cleanses over the years with it in pure water. Why don’t you humbly try it and see for yourself.
SAFETY CONCERN: Dr. Jockers, please correct your graphic and your text instructions in this article. One of the graphics shows dilution to 0.1% and the other with instructions says we are diluting to 1%. I believe the 0.1% is correct, but the discrepancy within this article is confusing.
Someone else caught this also: ET posted this same question on on January 6, 2022 at 6:01 pm . They also ask another great question: Also Dr. Levy recommends a much higher dilution for faster results.
Thanks for sharing and we made that update. Dr Levy does recommend using the straight 3% but there is higher risk for throat burning so we do the diluted method.
Thanks for the correction. But, also the title on the graphic also still says 1%.
When using the 2 drops of iodine nothing says how many times a day to use the iodine ?
Once daily for prevention, but if you are symptomatic, you can do this every 1-2 hours.
Hello, thank you so much for your article! You mention to use saline instead of water. What is the harm I’d just distilled water is used? Why does it have to be saline?
Hi Angela, Do know I am not the the Dr here, just a happy customer and former respiratory nurse. Saline, due to the sodium in the solution, is naturally found in your lungs and assists the cellular metabolism, absorbtion, etc in the cells of your lungs. Just using water, and more than you might naturally have, would not allow the appropriate exchange of ions and such. It can also be called ‘drowning’. Make the saline. Don’t just put water in your lungs. Saline is natural to your lung environment, plain distilled water is not. I hope this is helpful.
Yes, I agree with you Mikel S. Dr. Mercola strongly warns about not using water alone. It needs to be the saline solution.
I have a nebulizer and have never understood how to use it. The instructions don’t explain when the product like glutathione for example is coming out do you take a deep breath and inhale it and then hold your breath for so many seconds to allow the body to absorb the product or do you just breath normally with the mask on like you would without a mask and let the product get into the lungs. The actual breathing procedure is what I am wanting to know how you recommend using it. The company I bought the machine from doesn’t explain this information.
Have been wanting to do nebulizer H2o2 with my 10 year old, who has Down Syndrome, immune issues and gets a lot of upper respiratory infections. But in one article I came across it said this would be contraindicated in people with DS. It gave no explanation. Any idea why that would be?
Hello Tiffany, yes I don’t know why it would be contraindicated for people with DS.
This article on nebulizing is great. I would like to forward it to some of my friends but I don’t see a forward .
The options to share it are above the first big graphic at the beginning of the article, on the right. The one that looks like an envelope allows you to email it. Otherwise, you can always copy the web address, then paste it into a text, email, or post. Hope this helps!
Yes you can easily share this by sending your friends the URL link.
Could hydrogen peroxide be used in a cpap machine? And would a saline solution be used to and advantage?
Very valuable site! I followed Dr. Levy and nebulized 3% HP (non food grade). Only nebulized about 6 times (max 15m and once for 25 or so). I became a little concerned this could have caused permanent damage to the lungs/mucous membranes? Had slight burning in nasal cavity and that’s when I stopped. For future will dilute the saline/HP (food grade). Hoping you can comment to alleviate any worry. Thank you!
You should be fine and keep taking good care of your body and you should heal up well. If you want to nebulize the glutathione into these areas that can help. For your sinuses, you may also consider the Ion Sinus spray: https://store.drjockers.com/products/ion-sinus
Many many moons ago i used peroxide to beat my double cancers,
both in its state “3-to-5-days-left”. Am alive & kicking 3 decades later on.
W/ Ur nebulizer am concerned about teeth enamel, though.
Because peroxide is a well-known destroyer not just for enamel,
yet a whole tooth including!
Thank you for sharing Ur thoughts this matter, Doc.
Would love to know EVERYTHING you did. Am in the met BC battle now. And have issues in lungs. I have been nebbing c silver with distilled water & few grains sea salt.
Thinking of switching to peroxide. I have the food grade 35%.
Plus you drank it right? I have been scared to do this.
Thank you for the clearly written article. I already have a steam inhaler with mask for steam and aromatherapy use. Would this be sufficient to use with hydrogen peroxide or would you recommend I get an actual nebulizer? Thank you to you team for the wonderful information you share.
Hydrogen peroxide is fragile and so the heat of producing steam breaks it down, so the nebulizer does a better job of getting it into the lungs.
What about a cool mist humidifier? (I realize the nebulizer gets it into the lungs more efficiently). I’m thinking a cool mist humidifier would be helpful to either run at night while sleeping and/or running it during the day to help deplete viruses in the family room? If that’s a good idea, what would be the mixing instructions? Thank you for great info.
The hydrogen peroxide is very fragile and will combust in the air from the humidifier. I would recommend using essential oils for misting or diffusing into the air.
Respiratory Therapist here. I’m going to try and keep an open mind. Are you aware of any negative side effects from this method such as bronchispasms, etc.? I’m going to show this to our pulmonary intensivist to see what he thinks.
Brandon G. RRT-ACCS-NPS
I am not a medical professional as You are , but suffering from allergic asthma ,
Doctors have prescribed various sprays as Budesonid
Hello Brandon, obviously everyone is unique and different and it is possible that someone may have a reaction. With that said, at the dilution explained the in article, this is highly unlikely and we haven’t heard of anyone noticing any problems. Some practitioners use a full strength 3% H202 and say they rarely encounter any issues, however, our experience is that a lot of people get throat irritation from that strong a concentration. Hope that helps.
Do you breathe in through your mouth or nose? Or does it not matter and a combination of both is fine? Sorry if this is already mentioned and I just missed it.
If Your nose is “free” -always nose 🙂 It covers more of Your respiratory system and gets the right temperature
Combination of both is best!
We do not have a nebulizer but do have a cool mist humidifier. Can that be used instead of instead of the nebulazer?
May I ask why need Salt?
See Angel’s question above (Jan 13) and answers
I’d this recipe/formula safe too nebulizer on children? 3 years old
Yes it is.
You should include the phrase “food grade 3% hydrogen peroxide” every time you reference hydrogen peroxide. This is an important safety factor. Ordinary “medicinal hydrogen peroxide” should not be used. It is not recommended.
I have read to use a nebulizer machine that can produce particles in a range of 3-5 microns anything above that cannot actually enter the alveoli. Another point it made was to use a machine that used electrical outlet over batteries as they could not produce enough power to produce the smaller particles. I did find a portable machine that says it produces 3-5 micron particle and can use batteries or as a plug in unit. They do suggest using new batteries each time as the unit uses so much power batteries can’t be used over and over. Do you agree with this info.
Can I use distilled water instead of purified water to make the saline solution?
I would like to know if you sale the hydrogen peroxide
No we do not, but I have a link for it on Amazon in the article.
Hi Dr Jockers, Thanks for this article. We read to nebulize “2-3 ml” for “5 to 15 minutes every hour until you start feeling better.”
QUESTION: Being one who’s nebulized for years, 2-3 ml solution lasts only 4-6 min apx. So the amount vs duration above literally does not add up…
Please, will you clarify (the longer treatment 7-15 minute range), as it would take double the amount of solution (6 ml not 3ml) to achieve 15 minute? Either we 1.) double the amount or 2.) nebulize 3ml for apx 6 minutes. You can tap down the condensation in the chamber as it sputters to maybe extend to 7 minutes. But if it’s unclear to one who nebulizes it must be very confusing to those who do not. If ppl double the amount to nebulize for 15 minutes, can this cause any negative effects? Most sincerely – Thank you!
Yes you can safely double the amount in the recipe without any issues.
Thanks very much for clarifying DJ! 🙂
I saw you mentioned this is good for digestion – can you direct me to information on this? Would like to read up on this! Thank you so much
Yes this is due to the anti-bacterial impact of H202. It helps reduce bacterial colonies in the oral cavity that often make their way into the stomach/small intestine and can lead to SIBO.
If adding the iodine, is it 3-6 drops per the 8 oz saline/hydrogen peroxide solution?
Yes but start with the 3 drops and gradually work your way up to the 6.
I thought Dr. Brownstein says to add 1 -2 drops of Lugol’s 2% Iodine to the nebulizer cup along with the 3ml of h202 saline mixture?
Is it okay to add the iodine to the 8-ounce h202 saline mixture, and will it retain its strength? And if so, how much?
Please clarify for me! I nebulizer h202/saline solution often but not sure how to use the iodine.
Yes best to add the iodine to the mixture right before you nebulize the solution!
I’ve been wondering if H202 & glutathione can be nebulized together??
I’ve been nebulizing 3% h202 non-diluted, colloidal silver, & glutathione all separately for 2 years now and I can attest to H202 nebulized absolutely kills ANY bacterial/viral lung or sinus infections. I’m an asthmatic and for years I’d ALWAYS end up with pneumonia every single winter. Since starting H202 nebulized I’ve not visited Dr/ER nor taken a single antibiotic for lung infections. I’ve used on my mother(copd), husband, & 3 children and it ALWAYS kills the infection!!
I feel H202 does work better then colloidal silver nebulized for acute infections.
I start nebulizing H202 at first sign of any illness and usually knocks it out but sometimes I still get sick, especially if I don’t start treatment in time but as long as I continue nebulizing H202, sometimes every 1-2 hours if symptomatic.
No the glutathione will reduce the H202 and cause it to not have the extra electron on the O2 molecule that acts as the anti-microbial. I would do these separately. Thank you for sharing your experiences with these!
If I bought the 5 ml saline doses from the Amazon link in the article, how much Hydrogen Peroxide would I need to add to the nebulizer for each 5 ml dose?
A very small dose. You have to do the math based on the calculations in the article.
The link for your Nebulizer recommendation is no longer available on Amazon. Can you recommend another model? Thanks
Try this new one here: https://amzn.to/3tOodgO
Dr. Mercola recommended this nebulizer in 2020 and I’ve been nebulizing HP, CS and Lugol’s iodine using it since then. It’s fabulous, sturdy, powerful and no-maintenance. The separate battery pack isn’t needed if you plug it in to an outlet as I do. It’s small enough to travel with and I never leave home for more than a few days without it.
I saw the question about using a CPAP machine to “nebulize” 2H2O2 and other elements. I had the same question. Then I saw the post about heating disrupting the process. I also realized that the people that brought my machine recommended distilled water. I’ve used it for 6 years and never had a problem with any clogging. Long story short, I am in the process to get a nebulizer. However, is there something you would consider adding to a CPAP to assist with overall health?
Hello Ken, no we do not recommend adding it to a CPAP machine.
Is nebulizing H2O2 safe for someone with Hashimoto’s thyroiditis (hypo) and thyroid related eye disease (possibly Graves)? Thanks! (I won’t add iodine.)
Yes it is safe.
Great article. Nebulizing food grade H202 saved my life after a severe, late stage respiratory infection. My blood oxygen was dropping by the second so I nebulized with about 3.5 mls of 3% food grade (Bob’s Best) H202 and 2.5 mls of sterile saline. I found a weaker solution wasn’t as effective. Once I recovered I nebulized 1ml of H202 3% food grade, to 5mls of sterile saline. The missing link in my recovery was vitamin C powder. Once I drank 3000mg of quali C in water a few times a day, I felt a complete transformation. This works with the Nebulization treatment. Vitamin C helps create hydrogen peroxide.
If you notice symptoms early on, you can stop them in their tracks even quicker. but the fact is, I did not notice my symptoms for about 2 weeks and nebulized H202 still stopped the infection in a matter of hours!
The nebulizer I used was ‘A&D Medical UN-014 Compact Compressor Nebuliser’ you can buy one from Amazon and be sure to use the mask.
Without that treatment, I wouldn’t be here today. And don’t forget our body makes H202 to fight all kinds of pathogens.
Thanks for sharing and so glad you found this when you did! Praise God!
I’ve nebulizer with food grade 3% a few times, and my voice becomes very hoarse after. Is this typical?
Maybe. Ive noticed the same with my voice too. It may be due to using more than the recommended amount though. DR. Mercola recommends 0.04%. Ive been using a lot more.
Dr. Mercola recommends 0.01%
Dr. Brownstein recommends 0.04% which he says is the lowest % that works. Dr. Brownstein also uses ozone shots and lV h202
Personally, I make a solution with the percentage in between these two
That is too strong, try the dilution discussed in the article.
I know that % means out of 100, or divided by 100. Therefore, 1% = 1/100
Likewise, .01% = .01/100
1/100 = .01= 1 hundredth
But, .01/100 = .0001=
1 ten thousandth
I noticed in several answers, 1% solution was also written as .01% solution and this is not correct.
Hello, how do you recommend using H202 nebulization as a preventative? And can you use it daily or which should be the recommended approach for treating chronic infections or ashtma? Thank you!
Yes absolutely you can use this as a preventative health optimization tool. It can be very good for improving oral, respiratory and digestive health to do a session each day.
If I have access to Albuterol Sulfate 0.0083%, would that be as good as or better than the H2O2 for Covid-19 symptoms?
Nebulizing Albuterol makes me jittery and makes my BP soar. Nebulizing H2O2 kills pathogens, including Covid, and to my knowledge Albuterol does not, it is a steroid that reduces inflammation, thereby opening airways. I don’t use my Albuterol inhaler now that I nebulize H2O2, it’s been a life saver and life changer.
Great to hear that!
I have severe bronchiectasis with two species of pseudomonas a. bacteria in my lungs. Additionally, I have cavetary lungs. I live on nebulizing Cayston 75mg twice per day. Would nebulizing hydrogen peroxide do me any good/harm? I was told I would never be able to eliminate the bacteria so the best that can be hoped for is to keep it in check.
Sorry to hear about this! I would imagine with this dilution it should be helpful for you but always best to discuss with your physician.
Is nebulizing with mouthpiece only as good as with a mask?
The mask works best because it gets the H202 or whatever you are nebulizing into the nasal cavities and sinuses to help sterilize those areas as well.
I saw something similar to this on Instagram and had my husband nebulize what they recommended (50/50 purified water and 3% hydrogen peroxide). After he did this about 4-5 times I found your site and realized we had the wrong ratio and also should have used saline instead of plain water. Is my husband at risk for damage to his lungs? What should I do to have him checked out for any damage caused. I am freaking out and wishing I hadn’t trusted the other source. Thank you for any feedback!!
I am sure he will be fine Karly, the dilution is more for very sensitive people and it helps them with compliance. The saline makes it more effective.
Hello! Would nebulizing hydrogen peroxide be good for scleroderma? If not, would glutathione or another medication be beneficial for excess mucus caused by scleroderma? Thanks!
I would do nebulized glutathione for scleroderma.
Hi! Thank you for this!
What concentration for a 5, almost 6 yr old?
The recipe is the same no matter age, but it can be challenging to get them to keep it on their face.
Is the 3 to 6 drops of iodine added to the jar of saline solution or the nebulizer medicine cup with 5 ml of saline hydrogen peroxide solution?
The saline – H202 combination!
Pari-Trek is the nebulizer I have used for 2 yrs. quite successfully. Research online and find other suppliers. About $70. Have to buy a mask separately, but that should be available on the same site. One can buy a battery operated but it is expensive. This comes with a transformer that plugs into the wall.
I buy 12% food-grade H2O2 only. Make my own saline. Use distilled water only!!!! Do not use tap water. I often add a drop of Lugol’s 2% iodine I get off amazon. Be careful – its orange and stains. So I pre-make the saline with the H2O2 in a pint jar and keep in frig, follow directions above. Then add 1/2 t. at time of use into the nebulizer cup. The instructions in the article are straightforward and helpful. I am 72, no vaxx and no Covid or illness. Husband uses also at first sign of respiratory problems or been in a crowd, around sneezers/coughers – which we can avoid in our small town.
This is the nebulizer, Pari-Trek, that Mercola suggested. Haven’t seen it on amazon. We have used for a couple of yrs. now. Take with us when traveling in RV. We are in our 70’s, never vaxxed, never had Covid or the flu. We make a new solution and keep in the frig every 3 to 6 mo., but I don’t think its that neccesary. Follow the written instructions in the article (not the chart) which is easier to understand. Its very clear.
In use, it will provide mist for 10 to 15 min. Each of us bought our own mask (about $12?? – same site) and our own tubing. We are extra careful. Never rinse out the tube. If you see some moisture inside it, just hang it so it can drain and dry out.
Three months ago, Neil Cohen from YouTube’s EMF Safety Zone emailed me after I asked this question. Hi Neil. I’m thinking of buying a nebulizer. Several months ago, you mentioned that you were having trouble with your portable Omron MicroAir NE-U100 nebulizer when it comes to nebulizing colloidal silver. Could you please give me an update on how you are going with the nebulizing of this colloidal silver? You have led me to believe this may be the world’s best portable nebulizer. I’m thinking of buying it here in Australia. Could you please tell me if it’s worth buying?
Here is Neil’s response:
“I have found an issue with mine. I nebulize colloidal silver most often. and this jams up the nebulizer. I had to throw mine away and start buying cheaper ones on Amazon. so I have no suggestions at this point.”
After hearing this disheartening information, I completely lost interest in wanting to buy a nebulizer. I spent over two weeks researching for the world’s best nebulizer to buy and I was 100% convinced that the Omron MicroAir was it, but if it has trouble nebulizing colloidal silver, then what good is it?
In researching the perfect nebulizer to buy, I soon discovered that it’s not easy locating a high quality nebulizer when living in Australia. Once I discovered that the Omron MicroAir was no good, that’s when I stumbled upon the Omron A3 Complete. I thought, wow! This device looks impressive. Does it not only treat the upper airways, but it also treats the middle and lower airways due to the unique 3-in-1 adjusting of the particle size. I thought, oh wow, I definitely have to buy this, but as usual, you cannot buy high quality products in Australia. If I bought it from America, I wouldn’t be able to plug it into my Belkin powerboard, but not only that, Omron America and Omron UK do not post to Australia which was another huge letdown.
I thought, okay then. So my next step in my research was to hunt down a similar model that treats both the upper, middle and lower airways. After searching far and wide across the net, I could not locate a similar model. It would appear the Omron A3 Complete is a world first. It really saddened me that I could not buy this thing after doing all this research. I completely lost interest in nebulizers after feeling this huge letdown.
Simply put: What is the number 1 best nebulizer that I can buy in Australia that nebulizes colloidal silver without it jamming up, I wonder? If it’s not Omron, then I have no idea. All the nebulizers sold in Australia come with very little to zero consumer reviews. They look crappy and cheaply made in China. What if I were to buy my nebulizer from one of these less-known inferior brands, would they still stock filters and other spare parts two years from now, five years, ten years? Ha! I highly doubt it. I give up hunting down the perfect nebulizer. Too many things could go wrong which could lead to a waste of money.
I nebulize CS in my Amazon $100 nebulizer all the time. No problems at all getting jammed up. It might not be the “best” but as long as it is a plug in machine it can only help. Of all the doctors recommending and treating this practice, I have never heard any of them say it needs to be a particular model–just as long as it is a plug in as battery operated do not have the power.
You say the hydrogen peroxide/saline solution can be stored in the fridge for a long time..how long is a long time? I have some solution coming up on a year old and am thinking that’s too long and should probably make up some fresh solution.
Yes that is a while. I would say use it within 3 months.
Speaking with the actual producer of the peroxide (P: (425) 702-1805 | http://www.vivadoria.com) it was said that you cannot use a nebulizer that has any metal parts in contact with the peroxide as it will cause it to flash off (decompose) immediately. Portable battery operated nebulizers use a stainless steel vibrating reed to atomize the liquid so no good for peroxides. Same with any ultrasonic cold vaporizer, the transducer is SST also. That is why the Dr’s found poor results with the portables!
(By the way I expect that ionic silver water would agglomerate (deposit) on the metal parts of these nebulizers as well.)
The only way to go is an air compressor type nebulizer.
Next point they mentioned – adding salt to the solution will also cause the peroxide to decompose. The sodium is a metal!! I use distilled water. The Dr’s want saline because that is a bodily fluid, known to be safe. They are unaware of the chemical reactivity of peroxide. When diluting for short or long-term storage, always use distilled water. All other water types contain trace elements and minerals that react with and degrade hydrogen peroxide. Less of an issue – store in plastic bottles as glass can have small amounts of alkali metal ions dissolved in the surface also causing peroxide degradation.
High-density polyethylene (HDPE) provides the most stable surface.
Next point – be cautious of the type of peroxide you choose as many food-grade use synthetic stabilizers (non food-grade use heavy metals). Stabilizers keep the peroxide from naturally decomposing back to H2O and O2. Nasty to stick in your lungs. The synthetic stabilizers are actually worse than the heavy metals for your body! Call the manufacturer of your ‘food-grade’ and check if there are NO stabilizers or dig for the fine print on it. The only one I found with NO stabilizers is Viva Doria. No I do not work there or get $$ from them. This info is the result of too many hours trying to protect my family.
The Viva Doria decomposes naturally at a rate of 1%/year so the bottle will tend to pressurize over time with the released O2. A natural process. Expect it and don’t complain about it (as many do when the sealed shipped bottle comes pregnant).
Note I have emailed Mercola (who I love !) with all this info -crickets.
Next point – for clarity – add the iodine only immediately at time of use in the nebulizer. If added to the bulk batch of diluted peroxide it will decompose it!
Povidone [betadine] contains a synthetic polymer [good for external use]….go for ascent or Lugol’s- which is fairly easy to make with potassium iodide and iodine [prills].
Next point – real confusion of concentration to use in the nebulizer. Some of the Dr’s mentioned in this article errored with using metal based portable nebulizers and found that high % peroxides (3% ?) worked well, not realizing that most of it was instantly decomposed to water and a much reduced form was delivered to the lungs. Air nebulizers would deliver full strength. I find 3% eats my finger skin! No way am I using that in my lungs. As mentioned in the comments 0.01% and 0.04% were suggested by the Dr’s podcasts in summation of the procedure. I use 0.04%. I will experiment on myself (not my kids) with 0.1%. Bear in mind the 0.04% the Dr’s used was with a saline solution (degrades peroxide) so who knows how much got to the lungs! Hence they found the iodine was necessary to work effectively ! Go figure.
Last point – the catalase reaction equation at the top of this site is wrong – the products are 2H2O + O2, not 2H2O2 + O2. Minor detail but we need accuracy here!!!
Maybe the mods can edit this site to include the above details. Very important.
I hope you get a reply. This seems pretty important to address.
Thanks Steve. I am glad I read through all of the comments to get to yours! Dr. Jockers seems very attentive to the comments so hopefully he will respond to yours.
I have a 30% food grade without stabilizers, so I will dilute it according to the 36% instructions to have it be a little weaker than .1% I will keep it with saline to start but make it fresh each time so hopefully not much time to degrade.
Thank you for you diligence!
Excellent info, Steve. Thanks. I never got any benefit using the portable nebulizer recommended by Dr. Mercola. Your comments offer an explanation as to why. Would you be willing to share the nebulizer brand you’re using? Most of the ones on Amazon seem like no-name brands from China. Did you go with one of those or perhaps something like a Pari desktop?
Is there a protocol for someone with severe Asthma? will the nebulized peroxide program work? any info would be really helpful. Thanks!!
Just stumbled on this.
Your diagram “How Hydrogen Peroxide Works” appears to have a typo in it.
The diagram currently shows “2H2O2 –> 2H2O2 + O2.”
I think it should be “2H2O2 –> 2H2O + O2.”
For years, since following Justine Haynes on Happy Health, I’ve been using H2O2… as she recommended it…. recently with the ‘virus’, I have 3% H2O2 in my vaporizer and put that on for a few minutes each morning. It’s about 3ft. from me and I can lean into the mist and breath more deeply, but when my eyes begin to burn, I turn it off… thank you for bringing this to our attention… Justine was attacked like many others are for sharing the truth, so I was happy to send your article to her as renewed confirmation that she was on a good track all along. Thanks… I purchase the food grade 35% and make my own 3% solution to use with distilled water in litres.
Such great information. Thank you for keep this available. I need assistance with dosage. I’m using 3% food grade hydrogen peroxide. I have normal saline in a 10ml syringe. How much peroxide should I add to the syringe ?
Thank you to any one that paid attention in their math classes.
I have been diagnosed with bronchiectasis or Lady windermere syndrome.
In other words, my Dr said, “the tiny brooms in my lungs don’t sweep anymore.”
I ask about nebulizing with hydrogen peroxide. He said could damage my lungs.
I want to know if he or Dr. Jockers is right.
He has not mentioned this condition that I can find.
Any help will be so appreciated!
Your first article above, re; oxygen peroxide is this food grade or normal peroxide you get in a chemist/pharmacy?
sorry meant Hydrogen peroxide
Thank you, Your articles are always beautifully done & are outstanding teaching guides.
The only thing I would add here, is that you should explain very clearly, at the outset, that the ORDINARY hydrogen peroxide from the drug store shelves, should NEVER be used in nebulizing because of the additives it contains could be harmful. It should appear early in the article when hydrogen peroxide is 1st mentioned to make a clear & memorable impression. The article contains a lot of new information that can be overwhelming & you do not want this important information to get lost. Using bold & colorful type for this explanation at the start should help.
Hello, I was wondering if wI could nebulize 3% food grade HP straight without dilution. My brother recovered from pneumonia and Covid a year ago and he does it straight so I started doing it. It slightly burns my throat but I’m just wondering if it’s a big problem. I’m willing to do it because it’s just easier than making a diluted solution with the saline or filtered water. Thank you!!
Is this contraindicated in Pulmonary Fibrosis?
