Ozone therapy at home includes practices like rectalvaginal, or ear insufflationsozone saunas, or drinking ozonated water.

Some people also do injections and direct ozone IVs at home.

Buying your own generator means saving money over time, being independent from your doctor, and managing your health at the comfort of your home and at the pace and intensity that best suits you.

Here, you will learn how to find the right ozone generator, which type of oxygen to pick, and what other equipment you need.


What are all the things I need to buy? (a, b, c)


An ozone generator alone is of no use. To be able to perform ozone treatments you will need a combination of the following:

(a) Oxygen source

(b) Ozone generator

(c) Accessories

(d) Breathing protection

Here is why:

(a) Oxygen: Oxygen is the raw material from which ozone is generated. When you expose oxygen to electricity, you create ozone. Oxygen comes in either oxygen tanks or is produced by oxygen concentrators. 

(b) The ozone generator is where the oxygen is exposed to electric energy and is turned into ozone.

(c) The gas is then transported through tubings and other contraptions in order to deliver it into the body part of your choice. Accessories can be anything from connectors to foldable saunas or syringes.

(d) Ozone should never be inhaled. Breathing raw ozone can damage your lungs. It is important to protect yourself from accidental ozone exposure during ozone treatments. 


(a) What type of oxygen do I need?


You need either oxygen from an oxygen tank or an oxygen concentrator. 

The oxygen needs to be 

  • of at least 90% purity
  • be supplied in low flows of at most 1/8 to 1/2 LPM. (This is achieved with the use of pediatric regulators.)

There are two different oxygen sources which meet these criteria:

1. Oxygen tanks with a pediatric regulator.

2. Oxygen concentrators that produce at least 90% pure oxygen, with an external or built-in low flow regulator.

Oxygen Tanks


You can use different types of tanks for ozone treatments. 

Medical oxygen tanks can be used for all ozone applications, including injections and IVs.

O2Ready, ultra-high purity, scientific grade, and semiconductor oxygen is of the same or higher purity as medical oxygen.

Industrial oxygen tanks contain oxygen of 96% to 99% purity. They can be used for any ozone application, excluding injections.

Recommended sizes: 10 to 40 CF, or 200 to 1,100 L.

Price: $150 to $350 (including regulator and oxygen)

Pre-filled Oxygen Tanks ONLINE


There are several options to buy pre-filled oxygen tanks online from the comfort of your home: 

1. Promolife's O2Ready tanks. They contain oxygen of 99.6% purity. You can buy them online together with the fitting regulator. This service is available only to customers who live in the contiguous US or Canada. The tanks can NOT be refilled. They are sold in pair and hold combined 206 L of oxygen. You need to buy a special regulator for a one time fee. >> Check Current Price

2. They sell filled medical tanks online and ship them to you. You do not need a prescription. This is 100% legal (Thanks to changed Covid era regulations.). The tanks can NOT be refilled (at least not through them). Do NOT buy their regulator (It's high flow. You need low flow. This is the correct type of regulator.). Buy their tanks >> Check Current Price.

3. It is the same deal as with omssupply from option #2, but it's a different company. You will need the same type of medical, low flow regulator. >> Check Current Price

4. Amazon. Amazon has started selling FULL industrial oxygen tanks. It is not clear, what the purity of the oxygen is, but it likely ranges from around 96 to 99%. They can NOT be used for injections, but are fine for everything else. This is the regulator you will need for it. >> Check Current Price


Industrial Oxygen Tanks – CGA 540

Industrial oxygen tanks hold oxygen of around 96% to 99% purity. 

You can buy both full and empty oxygen tanks on amazon, your local welding shop, or gas supplier such as Airgas. 

Industrial cylinders can be refilled. Make sure that they have a DOT stamp and meet DOT and/or ISO regulations. 

Industrial O2 tanks are equipped with a CGA 540 valve and consequently require a CGA 540 regulator.

Industrial oxygen can be used for all ozone applications, excluding injections. 

Important information when buying industrial oxygen at a welding shop:

When buying industrial oxygen for ozone treatments at welding shops, one should be aware of a few things:

  • The staff will not be able to answer your questions about ozone therapy. As a matter of fact they may refuse to sell oxygen to you if they learn that you are intending to use it for therapeutical purposes.
  • The same applies for pediatric regulators. Welding shops don't sell those. You need to buy them online, see below.
  • Anyone can buy welding oxygen. You don't need a permit or a license for it. Consequently, welding shops usually don't ask people questions. But, should this happen, then say either “for my fish tank”, or “my husband/wife/son asked me to get it, I don't know what it's for”.
  • Do not mention ozone therapy or the word “therapy” in any shape or form ever.

Pro Tip #1

A good way to keep a chain of custody is to put a sticker on your tank and tell the sales staff that you'd like the same tank back. Do not swap tanks. 

Medical Oxygen Tanks – CGA 870

Medical oxygen tanks contain oxygen of at least 99% purity. They are equipped with a CGA 870 valve, and as a result require a CGA 870 pediatric regulator. 

You can buy pre-filled medical oxygen tanks online without a prescription and have them delivered to your doorstep. 

If you purchase an empty tank, you will need a doctor's prescription to get it filled. If you or a family member have asthma, bronchitis, COPD, emphysema, or any other lung condition, you may get a prescription for oxygen from your doctor.

Some places refuse to fill a medical tank even if you have a doctor's prescription. 

Pro Tip #2

If you want to have an empty medical tank filled, find an ozone doctor or ozone dentist in your area and ask if you could have your tank refilled through them. Some are open minded enough to say yes. If you become one of their patients first, then the doctor is more likely to agree to your request. 

Other types of oxygen bottles

Other types of oxygen tanks that hold oxygen pure enough to be used for ozone therapy includes: O2Ready oxygen from Promolife, aviation oxygen, food manufacturing oxygen, or Bernzomatic oxygen. 

Oxygen Concentrators

This is another popular source of oxygen. Having an oxygen concentrator means you will never run out of the gas.

Concentrators do not require refills.

They are an ideal solution for ozone saunas or making ozonated oil which require large amounts of oxygen.

Oxygen concentrators can be used for all ozone applications except injections and IVs.

Look for stationary oxygen concentrators which produce oxygen of at least 90% purity at continuous oxygen flows of 1 LPM or below.

Ideal are oxygen concentrators with a built-in low flow regulator for flows of 1/8, 1/4 and 1/2 LPM.

If you can't find such a machine, then make sure to get an additional external low flow regulator.

Do not buy portable or pulsed flow concentrators. 

Price: $150 (used) to $1,500 (new with Rx)

New oxygen concentrators

New machines require a prescription from your doctor. If you or a family member suffer from a lung condition or sleep apnea, you can ask for a script from your general practitioner.  

Price: $800 to $1,500 and up (you will need a Rx)

Available at:


Refurbished oxygen concentrators

They do not require a prescription and often cost considerably less than new machines. The concentrators have been inspected and if necessary repaired, are in good to very good condition, and often come with a warranty. 

Reconditioned oxygen concentrators are a great solution for home ozone users when buying your own ozone set-up.

Price: $400 to $800

Available at:



Used oxygen concentrators:

You can buy used oxygen concentrators on Ebay or Craigslist.

The average life span of an oxygen concentrator are 35,000 hours. Do not buy machines with more than 15,000 hours. Anything below 5,000 hours is worth looking into.

Make sure to test the machine for several minutes. The concentrator should run smoothly, not turn itself off, or have the alarm go off.

Price: $150 to $400

Industrial generator vs. generator for ozone therapy: how do I know the difference? (b)


Industrial ozone generators are typically used for applications like home remediation, car odor removal, or swimming pool treatments. They produce ozone amounts which are multiple times above what is produced by therapeutic ozone generators.

An industrial ozone generator should never be used for personal treatments since it can cause great harm.

When buying an ozone generator for personal treatments it's important to be able to distinguish an industrial ozone appliance from an ozone therapy device.

In the chart below on the left side you will find five criteria which every ozone therapy generator must meet.

Ozone Therapy Generator vs. Industrial Ozone Generator

Ozone Therapy Generator

Industrial Ozone Generator

✔︎ ozone output chart is provided

✘ only max ozone output is known

✔︎ ozone concentration is in mcg/ml, ug/ml, mcg/cc (often referred to as “gamma”)

✘ ozone production is in g/h or mg/h

✔︎ uses oxygen as feed gas

✘ uses air as feed gas

✔︎ low oxygen flows of 1/8 to 1/2 LPM on output chart

✘ no flows 

✔︎ it's possible to use ozone concentrations of 20 to 60 mcg/ml at flows of 1/2 to 1/8 LPM

✘ only maximum ozone output in g/h or mg/h is given




If an ozone generator fulfills all the criteria listed on the left, then it’s safe to be used for home ozone treatments.

Which accessories do I need? (c)


Buying an ozone generator for home use includes purchasing the necessary add-ons so that you can perform your preferred applications. 

Below you will find the most important attachments and glass ware to be able to perform ear, rectal, vaginal, nasal insufflations, ozone saunas, all forms of injections, breathing ozonated olive oil, ozonate water and oils, do dental treatments and use the body suit. 

(1) Breathing ozonated olive oil (BOOO)

Accessories needed: (1a) trap, (1b) oil bubbler, (1c) nasal cannula

Instructions on how to do BOOO.



(1a) Trap

The trap protects your ozone generator from oil. Whenever you bubble ozone through oil, some oil travels back through the tubing. Once oil reaches the ozone chamber, the ozone generator can't be reclaimed. A trap is the best way to protect your ozone machine from oil damage.

Gas washing bottles or empty oil bubblers or humidifiers can be used as traps.

Available at:

(1b) Oil bubbler

The bubbler is a special glass container for the olive oil. In the middle of the container is a stem. When you pour olive oil into the bubbler, the stem should be sufficiently covered by the olive oil. The ozone/oxygen gas mix then travels through the stem and through the oil and bonds with it to form ozonides. The stem of the oil bubbler should NOT have a stone, but one or a few holes instead.

If you decide to use a gas washing bottle as an oil bubbler: suggested size is 250ml.

Available at:

(1c) Nasal Cannula

The cannula transports the ozonated olive oil into the sinuses. Instead of a cannula you can also use an oxygen mask.

Available at:

(2) Dental treatments

Accessories needed: (2a) dental handpiece with tip needles and tooth cups

(2a) Dental handpiece

The handpiece allows the dentist to direct ozone to specific areas in your mouth. It can be used either with blunt needles or with tooth cups. Promolife offers a full set of dental accessories.

Available at:

(3) Ear Insufflations 

Accessories needed: (3a) trap, (3b) earscope

Find instructions on how to do EI here


(3a) Trap

The trap muzzles the noise of the ozone generator. Without the trap the sound of the generator is amplified by the earscopes. This can lead to ringing in the ears for some time afterwards.

Available at:


(3b) Earscopes

Eearscopes transport the ozone into the ears. They are a sort of modified stethoscope.

Available at:

(4) Ozone Injections

Ozone can be injected into the muscle (intramuscularly), under the skin (subcutaneously), or into the join (intraarticularly).

Accessories needed: (4a) filter, (4b) syringe, (4c) needles

(4a) Filter

Attach a filter to the ozone outport of the ozone generator whenever you fill a syringe. The filter removes any impurities and makes sure you inject just pure gas.

Available at:

(4b) Syringe

Syringes used for ozone injections should be ozone resistant. There are two different solutions for this: a) glass, or b) poly-carbonate syringes with a silicone stopper.

Available at:

(4c) Needles

Needles come in different sizes and lengths. The circumference of the needle is given in g, or gauge. It ranges from 34g to 10g, with 34g being a needle with a very small diameter, and 10g a needle with a big diameter. The lengths range from few millimeters to 10 cm or more.

For subcutaneous injections 27g to 30g needles of around 13mm (1/2″) length are used.

Intramuscular injections go deeper and call for a longer and thicker needle. Here typically sizes of 20g to 22g and 40 mm (1.5″) are used.

Intraarticular injections require different sizes and lengths depending on the size of the joint. For knee or shoulder injections  22g and 40 to 50 mm (1.5 to 2″) needles are required.

For smaller joints a 25g and 0.5″ needle can be used. Joint injections should be only performed by medical professionals.

Available at:

(5) Intravenous Injections

Accessories needed: (5a) filter, (5b) syringe, (5c) butterfly needle

(5a) Filter

Whenever you fill a syringe you should attach a filter to the ozone out port of your ozone generator. The filter removes any possible impurities and makes sure you don't inject any particulate matter, just pure gas.

Available at:

(5b) Syringe

Syringes used for ozone injections should be ozone resistant. There are two different solutions for this: a) glass, or b) poly-carbonate syringes with a silicone stopper.

Available at:

(5c) Butterfly needle

Butterfly needles are used for direct intravenous injections. The buttflies allow the syringe to be fixated on the patient's arm with a piece of tape.

The recommended size is: 27g, 1/2″.

Available at:

(6) Ozonate oil

Accessories needed: (6a) trap, (6b) oil bubbler, (6a) trap, (6d) destructor

​Find detailed instructions here.

2 x (6a) Trap

When ozonating oils, it's very important to use an empty trap to prevent oil from the oil bubbler from flowing into the ozone generator. Once oil gets into an ozone machine, it can not be saved anymore.

When ozonating oils you also want to use a second trap between the oil bubbler and the destructor to prevent oil from getting into the destructor and clogging it.

Any gas washing bottle can be used as a trap.

Available at:

(6b) Oil bubbler

The bubbler is a special glass container for the olive oil. In the middle of the container is a stem. When you pour olive oil into the bubbler, the stem will be submerged under the olive oil. The ozone/oxygen gas mix then travels through the stem and through the oil and bonds with it to form ozonides. The stem of the oil bubbler should NOT have a stone, but one or a few holes instead.

When doing BOOO (Breathing Ozonated Olive Oil) the byproduct is ozonated olive oil. Instead of tossing it once it's saturated, you can use it for topical applications.

Available at:

(6c) Destructor

A destructor neutralizes ozone. After ozonating oil, there is a lot of excess O3 gas. Instead of releasing it into the room, it flows into the destructor where it's eliminated.

Available at:

(7) Ozonate water

Accessories needed: (7a) trap, (7b) water bubbler, (7c) destructor

​Find instructions on how to ozonate water here

(7a) Trap

The trap protects the ozone generator from backflowing water. Once water reaches the ozone chamber it can cause a short circuit.

Any gas washing bottle can be used as a trap.

An alternative is also a check valve.

Available at:

(7b) Water bubbler

The water bubbler is a glass container with an ozone inlet and an outlet and a stem with a stone. You pour enough water into the bubbler so that the stem is submerged.

Promolife bubblers come with the destructor already attached to the top of the bubbler.

Gas washing bottles, glass jars, or empty, clean wine bottles can be also used as water bubblers.

Available at:


(7c) Destructor

A destructor eliminates ozone gas and protects you from breathing it.

You either buy the destructor separately, or you but a Promolife water bubbler with the destructor already a part of it.

Available at:

(8) Ozone body suit

Accessories needed: (8a) ozone resistant body suit

Find instructions on how to use it here

(8a) Ozone resistant body suit

The suit should be big enough to accommodate the entire body. Everything should fit inside from your feet to the neck. You should wear a towel or a mask in order to prevent the excess ozone from escaping and breathing it in.

Available at:

(9) Ozone sauna

Accessories needed: (9a) extra long silicone tubing, (9b) sauna tent [or hard shell]

Fin instructions on how to set up an ozone sauna here

(9a) Extra long silicone tubing

The silicone tubing transports the ozone gas into the sauna tent [or the hard shell sauna].

I recommend lengths of at least 5 ft. The longer the tubing, the more flexibility you have with where you want to place your equipment.

A great diameter size is 3/16″ ID x 5/16″ OD. This fits great with luer, quick, and most other connectors.

Available at:

(9b) Sauna tent

This can be either a steam sauna, an infrared sauna, a hard shell box, or a sauna dome. What is important it should allow for the head to stick outside to prevent breathing in ozone.

If you decide to go for an infrared sauna, make sure the heating elements are ozone resistant.

Available at:

(10) Nasal insufflations

Accessories needed: (10a) a syringe

(10a) Syringe

Use either a 20 cc or a 60 cc syringe. Promolife also offers syringe covers which offer additional comfort and hygiene.

Available at:

(11) Rectal insufflations

Accessories needed: (11a) 200ml syringe, (11b) catheter

Find detailed instructions here

(11a) 200 ml syringe

This is the most accurate and the best way to perform rectal insufflations. Another option are bags

Available at:

(11b) Catheter

A catheter transports the ozone gas into the colon. Best options are catheters with a luer end. The circumference should be 14 or 16 Fr. and the length at least 6″.

Available at:

(12) Vaginal insufflations

Accessories needed: (12a) catheter

Find detailed instructions here

(12a) Catheter

A small piece of silicone tubing, a luer connector and a catheter, that's all you need to perform vaginal insufflations.

You can also use Promolife's reusable silicone catheter. In which case you'll need this adapter.

Available at:

(13) Additional equipment

A list of add-ons which may be necessary to connect the ozone equipment with the various accessories.

Connectors: luer, quick, adapter

In order to be able to connect silicone tubings with catheters, bubblers, and other accessories, you will need different connectors. The adapter serves to connect catheters with a funnel end with silicone tubing.

Available at:


Protects you from breathing in excess ozone gas. 

Available at:

Check valve

A check valve blocks the flow of liquids into the ozone generator. It's a great alternative to a trap. 

Available at:

Syringe filling station

A syringe filling station is great for DIVs: it enables the user to keep the syringe always upright during the filling and so to  prevent air from entering. The attached destructor eliminates any excess ozone. 

Available at:

Additional silicone tubing

You will need extra silicone tubing if you're doing ozone saunas, or if you have many different ozone accessories to connect to each other. A great size is ID 3/16″ x OD 5/16″. Gas washing bottles may require bigger tubings.

How much does everything cost?


When buying an ozone generator for home treatments you must calculate with an expense of a minimum of $900 plus shipping.

On average, people spend around $1,500 to $1,800 for their ozone equipment including oxygen.

Below, I present three different examples for three different budgets: less than $1,000, $2,000, and for around $8,000.

Tips to save money

1. Buy used ozone equipment

The best place to check for used ozone generators is in the Facebook group The Ozone Group with currently over 11,000 members.

Members regularly post ozone equipment they want to sell. The machines are often in great shape and only lightly used.

In order to have access to the group, you need to apply and answer all three questions. Only then will you be admitted.

Another place to look for used equipment is Ebay or Craigslist where you can find great deals especially for oxygen concentrators.

2. Take advantage of discounts and specials.

Promolife and SimplyO3 regularly offer holiday specials for Thanksgiving or Christmas or other occasions. Stay up to date with specials by subscribing to their newsletters. 

Additionally, you can get year round discounts by using the following codes:

Promolife offers 7% off on all ozone equipment if you use my code. Subscribe to my newsletter to receive it. 

SimplyO3 deducts $50 from your order of a Stratus2.0 or Stratus3.0 machine if you use POWER.

3. Buy a no-frills ozone generator

Buying a simplified ozone generator is another way to save money. Those are machines like Promolife Mini.

Their ozone concentration is controlled through the oxygen flow, not through a dial knob. They only have an on and off switch.

This comes with a reduced number of options to set the ozone concentration. 

Most ozone applications call for ozone strengths in the 20 to 50 mcg/ml range which all of the simple generators offer. 

The HTU-500 is also a great solution if you are more of the DIY type.

4. Buy more affordable accessories

For most of the accessories there are more affordable alternatives.

Example: gas washing bottles instead of bubblers and traps. You can buy a gas washing bottle for 1/4 of the price of the more expensive equipment. (You may have to experiment which tubing to buy to fit the outlets.)

Catheters: buying them in bulk from this place for example can push the price down to $0.85 per catheter instead of $2 to $4 at the ozone suppliers. 

5. Reuse it

Another solution: sterilize and reuse catheters. Especially catheters used for vaginal insufflations can be easily rinsed out and utilized again.

Catheters which have been used for rectal insufflations, should undergo a more thorough cleaning: some people soak them overnight in 3% H2O2, rinse them out with water really well before re-applying again. 

6. Use your creativity – DIY it!


Instead of a water bubbler, just use an empty and clean wine bottle to ozonate water. Or a water jug. Just make sure to leave the room while the water is being infused with ozone.

Use a check valve instead of a trap.

Or simply use gravity and put the container with the liquid well below the ozone generator (I would pair this with at least another method to prevent backflow.)

Or save on both trap and check valve, but make sure that you disconnect everything in the right order: first, turn off the ozone generator, then disconnect the glass ware with the liquid, and as a last step turn off the oxygen. (This is risky. If you forget the right order, it may result in oil getting into your ozone generator after which the machine is useless).

Another solution: use the direct method of doing rectal and vaginal insufflations instead of bags or syringes. Just insert the catheter while it's attached to the ozone generator.

With RI, this direct approach should be only used with very low oxygen flows of 1/16 or 1/8 LPM and you should use a timer to make sure that a certain amount of ozone gas isn't exceeded.

7. Buy ozone packages

Promolife, SimplyO3, and Longevity all offer extensive ozone packages. Buying all the ozone equipment and accessories as a bundle is often more economical than when buying everything piece by piece.

8. Use payment plans

While buying ozone set-ups through payment plans does not reduce the total amount spent, they allow you to stretch out your expenses and make it more realistic to purchase. If you don't have the whole sum ready, you can pay it off in installments.

Promolife offers this option through their PayPal Credit plan.

9. Sign up for affiliate programs

If you are happy with the ozone equipment you bought, you can become an affiliate and start promoting your favorite ozone company.

Promolife, SimplyO3, and Longevity all offer partner programs. Once you have singed up, you can earn between 5 and 10% on sales you have facilitated. This is how I made thousands of $ over the past few years – without even being a prolific writer!

Or you can suggest your favorite equipment in emails to friends and other people who may inquire about it. 

Affiliate programs are a great way to get back the money you have spent on your ozone equipment.

Sending emails doesn’t cost anything!

Or start blogging about your ozone adventures. There are many blogging services which allow you to start your own website for free. By embedding affiliate links in your blog posts you could create a side income for yourself. 

10. Buy in bulk!

Some companies, like for example Longevity, offer price reductions if you buy more than one machine. Do you have friends who also want to buy an ozone generator? If so, get together and place the order as one person – Longevity will give you $145 off on the EXT50 (so you'll pay $850 instead of $995 per machine).


Buying an Ozone Generator in Australia



The most convenient way to buy at least 99% pure oxygen is an industrial oxygen bottle from Bunnings

You pay a $200 fully refundable deposit and $69 for a filled 2,100 L bottle. Promolife offers matching pediatric regulators.

Other options include opening accounts at Onegas or BOC and buy medical oxygen. You may need to show a doctor's letter to be able to open an account.

At BOC you pay a monthly rent of AU$11.5 and a new refill costs AU$35. For a medical bottle you will need a medical regulator.

You can also buy a used oxygen concentrator on Ebay.

Ozone generator and accessories

Naturalozone is an online shop located in New Zealand which serves the Australian and New Zealand market. They offer a great ozone generator for personal use for $ 1,500 NZD. You can also buy the most important ozone accessories in their online shop.

The next best solution is through either Promolife, SimplyO3, or Longevity. All of those companies offer matching accessories like glass ware, catheters, connectors etc.

Truly Heal is also located Australia. Here you can read my review of their ozone package.

Alternatively, you can also buy gas washing bottles on Australian Ebay.

Buying an Ozone Generator in Europe



In many European countries medical oxygen can be bought easily without a doctor’s prescription.

There are several online shops which offer filled oxygen bottles plus low flow regulators.

This is true for Germany, Netherlands, and France, see here.

In Italy, many pharmacies refill oxygen bottles.

In Poland, you can buy technical or 100% pure oxygen online and have it delivered to your home.

In Germany, several companies sell pediatric regulators.

Ozone generator and accessories

The best solution to buying an ozone generator for Europe is to purchase it from one of the North American sellers.

As far as I know, there are no known German or EU based manufacturers who sell ozone machines to the general public.

Ozone therapy is quite popular or it’s gaining in popularity among doctors in many European countries including Germany, Italy, Spain, Austria, Switzerland, and Poland, but it’s unheard of for people to treat themselves at home with ozone. Most patients go to their doctor or natural health care practitioner for ozone treatments instead.

Luckily, all the recommended US and Canadian producers of ozone generators are also catering to an international crowd: all their ozone generators run on universal voltage. Check out the online shops of Promolife or SimplyO3

And all of them offer low flow regulators which fit European and Australian tanks.

Take note that you may have to pay customs fees when importing ozone generators. How much – this depends on the country you’re in.

Buying an Ozone Generator in the UK



Buy industrial oxygen tanks online from BOC. You can order them online and they will be delivered to your home. If you have an old empty tank, then it will be swapped out for the new full tank. The E size tank holds 680 L of oxygen and is a perfect size. Promolife sells the fitting pediatric regulators. 

Other options are buying used oxygen concentrators on Ebay or here.

Ozone generator and accessories

Just like with Australia and the EU, the best option appears to be buying the ozone machine and the accessories from either Promolife, SimplyO3, or Longevity, all of which have international customer services.

Frequently Asked Questions


How important is it which materials the ozone generator is made of?

The materials which are used inside the ozone path are very important. Ozone is highly corrosive and it will break down as good as every material. There are just a few exceptions, like: stainless steel, titanium, aluminum, glass, ceramic, silicone, kevlar, and a few others.

Is it important for you to know which of those materials are used in your ozone generator?

In my opinion – no.

Just like you don't have to know all the heat resistant materials a grill is made of before you buy it. 

It's enough that the manufacturer knows that. It's clear that no producer of grills will use materials which will be destroyed by heat at the first use of their product.

The same thing applies for manufacturers of ozone generators: it's clear that they will only use ozone resistant materials, otherwise the machine would break down very soon and no one would buy it.

In spite of the obvious logic, I'm aware that the thought may still appear controversial to some.

Many people have bought into the idea that the only acceptable type of ozone generator is one which has an ozone chamber made entirely out of glass (a so called dual dielectric ozone generator). And that ozone should never get in contact with metal, not even with highly ozone resistant metals like stainless steel, titanium, or aluminum.

What few are aware of is that this belief emerged solely thanks to the tireless efforts of the main manufacturer of all-glass ozone generators.

True medical grade ozone generators, so machines like Herrmann, Humares, Ozonosan, or Sedecal (Ozonette), some of which cost up to $15,000, are made of ozone chambers which allow stainless steel and other metals to get in contact with ozone. These machines have to satisfy the highest quality requirements since they’re true medical devices according to European regulations. This means that the manufacturers had to prove that they do not pose a risk to human health. 

This fact alone renders the argument of the all-glass purists mute.

All the ozone generators on this list are made of ozone resistant materials.

What about the ozone generators on Alibaba?

On alibaba you can find a whole selection of Chinese ozone generators which cost between $200 and $250. They claim to be medical grade, they have an output chart printed on top according with the oxygen flow, and look like some of the generators sold by US retailers. Looks legit and like a great way to save some money, right?

There is one big problem though: their ozone output charts can’t be trusted.

Here is why you should be careful when buying an ozone generator on alibaba: many of those generators have a chart printed on top which distinguishes between two different oxygen sources: tank and concentrator.

The oxygen purity between an oxygen concentrator and an oxygen tank which is used for an ozone generator should differ at most by 10%. Since oxygen concentrators used for therapeutic ozone generators should put out oxygen of at least 90% purity, and oxygen tanks contain oxygen of at least 99% purity.

Consequently, the ozone output between those two oxygen sources should also vary by at most 10%.

But that’s not the case with the cheap Chinese models.

There, the ozone concentration differs by up to 150% between oxygen concentrator and oxygen tank.

Testing performed by SimplyO3 revealed that those numbers are indeed not correct.

Other ozone machines sold on Alibaba have an output chart which shows one ozone concentrations for pure oxygen source and one for air as feed gas. Which shows that they were not made for therapeutical purposes. Which is fine, only that they are often advertised as medical devices.

Yet other ozone generators claim to have a design “Made in Germany” and engineering “Made in Italy”. Only someone not familiar with the European culture would advertise such a thing. And it shows that the sellers are willing to post no matter what outlandish claim about their machines in the hope of attracting buyers.

Which of those claims is true is for most people impossible to verify.

Cold, hot corona, or UV light: which type of ozone generation is the best?

When reading the technical specifications of various ozone generators, you will find that different manufacturers seem to want to outbid each other in whose machine is the coldest. Every one of them claims to build machines with a cold corona or a true cold corona or the truest cold corona generator ever.

Why is it important whether an ozone generator produces heat or not?

Heat destroys ozone. The hotter an ozone generator gets, the more unstable its ozone output will become. Which means that with prolonged running time the produced concentration will start to decline sharply. 

Every type of ozone production generates heat to some degree. There is no such a thing as a completely cold ozone generation.

This is why most manufacturers of ozone machines have found solutions like low ampere, ceramic cells, or fans inside the machines.

Is the type of ozone production important for the outcome of ozone treatments?

No, it’s not. Ozone is ozone, it’s still O3. It does not matter whether it was produced by a corona discharge or UV light as long as it was produced from pure oxygen.

Do oxygen concentrators produce harmful nitrogen oxides?

Some ozone experts claim that one should only use oxygen tanks for the production of ozone and never oxygen concentrators. Oxygen concentrators produce oxygen of around 90% to 97% oxygen. But what are the remaining 3% to 10%? Ozone experts say it’s mostly nitrogen which then converts to harmful nitrogen oxides.

I wanted to find out if that was indeed true and contacted three different producers of oxygen concentrators. Two of them responded. They explained that:

Oxygen concentrators have zeolite filters. The main function of zeolite is to pull nitrogen from the air.

  • One said that the remaining 3 to 10% which is not oxygen is a combination of argon and CO2, not nitrogen.
  • The other said that the remaining 10% are maximum 5% nitrogen, the rest is argon and CO2.

So is it possible that the maximum 5% nitrogen could cause harm when exposed to ozone?

Unlikely, here is why:

There are three potentially problematic nitrogen byproducts:

1. NOx, which stands for NO and NO2, or nitric oxide and nitrogen dioxygen.

NO plays an important physiological role in our bodies, it’s a vasodilator and neurotransmitter. This is one of the reasons why people take L-arginine which produces NO.

NO and NO2 have been implicated in various health conditions. They are considered part of smog and are taxed or regulated by most Western governments.

After looking in depth into the issue, which included reading studies cited by the World Health Organization in its report on nitrogen oxides, I had to come to the conclusion that there is no evidence to support that NO or NO2 have any negative health impact on humans or animals at levels of 10,000 times of urban NOx levels. See my Facebook post on the matter.

NO and NO2 are produced 90 to 95% by trees, soils, and volcanoes. Only 5 to 10% are produced by humans. [1] [2]

There is no evidence that neither NO nor NO2 are harmful to human beings.

In spite of the facts and countless studies which prove that they are harmless or even beneficial [3] [4] [5] [6] [7] [8] [9] [10] even at multiple times of normal atmospheric levels, governments have nevertheless decided to tax and regulate them.

Together with similar approaches towards CO2 [11] and ground level ozone, all of which are naturally occurring parts of air and are overwhelmingly produced by nature, not humans, this type of government sanctioned and government promoted misinformation serves more to highlight the current Orwellian push towards totalitarianism at the hands of “towering geniuses“, and has nothing to do with the actual risk of those molecules.

2. HNO3, or nitric acid, is a highly corrosive acid that can damage even stainless steel.

Is it then possible that ozone generators which use oxygen produced from oxygen concentrators produce nitric acid?


Here is Jeol Leusink's answer from the company Oxidation Technologies explaining it. His company specializes in the production of industrial ozone generators some of which run on air as feed gas (air contains 80% nitrogen):

“(…) if ozone is produced from air as opposed to oxygen, and that air is not sufficiently dry, then HNO3 can be produced from the nitrogen and hydrogen found within that air. 

To eliminate HNO3 production in the ozone generator remove all hydrogen in the air supply by drying the air, or use oxygen feed-gas. 

The danger in HNO3 production with an ozone generator has much more to do with the longevity of the ozone generator, and parts in the gas stream prior to the water.  The HNO3 production rate is very low, and will not affect the water in any measurable amount.  However, HNO3 production within the ozone generator and piping will cause reliability problems very quickly, within weeks, or days of operation.”

The oxygen produced by oxygen concentrators is extremely dry. Concentrators use several air filters including zeolite filters. They extract all humidity from the air, to the point that patients who are prescribed oxygen machines for lung conditions like COPD are instructed to use humidifiers to not hurt their lungs.

Conclusion: There are no harmful nitrogen byproducts generated during the production of ozone with oxygen from oxygen concentrators.

On a personal note:

During an ozone course in Nizhny Novgorod, Russia, I witnessed the use of oxygen concentrators for any type of ozone applications. Ozone medics in Nizhny Novgorod are pioneers in the field of ozone therapy. This is where the ozonated saline IV aka “Russian method” was developed. Oxygen concentrators are regularly used in Russia without apparently causing any problems.

  1. Dennis Hannon

    Hi Paola
    I have almost everything I need.
    However I require a low flow regulator to attach to my concentrator. And preferably from Australia, to save on exchange rate and international postage.
    Thanks for your advice.
    Kind regards

  2. John

    Hi Paola, After viewing your videos and reading your comments and fabulous advice re the benefits of Ozone I decided to take the plunge and started to put together a kit from different sites such as Promolife, NaturalOzone, Amazon etc. Now being in Australia you recommend a New Zealand Company Natural Ozone and they do have great customer service and are very helpful but I do have a slight concern where you recommend their Ozone Generator the site sells (NZ$1500 – Ozonode) which looks exactly like an item you can find on AliExpress for NZ$300 some NZ$1200 cheaper – Manufacturer for this is Aquapure) with exactly the same specifications. The NZ site also sell an Oxygen concentrator which looks identical to one on eBay except for the labelling for (NZ$1000 whereas the one on eBay sells for around NZ$300 – Now I noticed in some blog that you actually don't recommend the oxygen concentrator, but I was wondering on your comment where you say Chinese made Generators such as found on AliExpress are inferior where the generator I found has exactly the same configuration, dimensions, outlets, knobs, buttons etc., that Naturalozone sells. German design, quartz corona discharge cell with titanium electrode technology features Italian made glass giving stable and long lasting pure ozone output levels. I take it you haven't purchased one of these Ozonode generators from NZ but would appreciate your comments on how I can test the Ozone output of the $300 machine I purchased on AliExpress as to me it looks identical. It is shown on youtube (AOT-MD-520 Medical Ozone Generator) They also have a digital model that can be used for Blood IV as has a vacuum pump (AOT-MD-500A) – These look like great alternatives so would appreciate any comments you have on them. a big thank you for all the great information.

      Hi John,

      that is true, I haven't tried those ozone generators out.
      But not everything that is Chinese made must be bad … If they have a local (meaning New Zealand) place where you can come to them with problems that they can fix, then this would be a big plus, I think.

      As to the oxygen concentrator, I took a look at it. It is not fit for ozone use, in my opinion. It produces too low oxygen purity (80%) at a flow of 2 LPM. You need to have 90% or above at that flow, so that you can feed it into the external low flow regulator:

      You can test the output of the ozone generator by either buying your own ozone analyzer (between ca. $1,500 and $5,000) or send it into Promolife's testing service:


  3. Wesley Lounsbury

    Hello Paola,

    I currently own a Dr. O Solutions ozone medical grade generator. Can you tell me why this machine is not recommended for anything other than ozonating fruits and vegetables and water? Thanks for all you do, you are beautiful human being.

    • Paola Dziwetzki

      Hi Wesley,

      I don't recommend the machine because of its obvious low quality. I don't think I would feel comfortable using it for anything else, given that it has been designed with non-medical air-fed protocols in mind.

      But if you use it with oxygen, you may be OK …. I personally would not use it for much more than fruits and vegetables.
