Oxygen for Home Ozone Treatments

When you're getting ready to do ozone treatments at home, you will need an oxygen source in order to produce ozone.

You have the choice between oxygen concentrators and oxygen tanks.

Both have pros and cons. A concentrator offers independence, an oxygen tank offers a higher purity.

There are medical oxygen tanks (CGA 870) and industrial oxygen tanks (CGA 540). Both require low flow (pediatric) regulators. Industrial tanks can be filled at welding shops. Medical tanks require a doctor's prescription.

Oxygen Tank vs Oxygen Concentrator: Pros and Cons

Every ozone generator used for home ozone treatments has to be fed by an oxygen source.

There are two basic options: concentrator or tank.

Noise level Moderate None
Consumes electricity Yes No
Requires refills No Yes
Requires filter changes Yes No
Requires regular maintenance/testing Yes Yes
Risk of injury Minimal, unless placed too close to a fire source when on Tank is under extreme pressure; should not be placed close to a fire source when open; should be out of children's reach
Cart Not needed Highly recommended
Nitrogen content 3% to 10%   0
Oxygen purity Varies, usually 90% +/- 5% 99% and up
Low oxygen flow

Needs to be remodeled or used with an external regulator for $150

 Pediatric regulator for $20 to $120
Cost High upfront cost, low running costs for power consumption Low upfront cost, higher running costs for refills.


Concentrators take in the ambient air which is made out of around 78% nitrogen and 21% oxygen, put it through filters and a compressor and out comes a gas mix of around 95% (+/-) oxygen, some argon, nitrogen and CO2.

Most concentrators produce O2 flows between 0 and 5 liters per minute which is too high for ozone therapy. Ozone applications require extremely low flows between 1/32 to max 1/2 liter per minute. Concentrators with low flows are more difficult to find and often cost more than concentrators with higher flows.

An external low flow regulator can be attached to a high flow oxygen machine, and so “remodeled” into a low flow concentrator.


Concentrators fit for ozone therapy should produce oxygen of at least 90% purity.

Nearly all concentrators use zeolite filters which filter out most of the nitrogen. The remaining 5% to 10% are a mix of argon, some carbon dioxide (CO2), and nitrogen left-overs. 

Protocols like insufflations, ozonating water, ozone saunas, bagging and in general everything that is not invasive can be performed with oxygen concentrators.

Oxygen concentrators do not require refills like tanks. With access to electricity, one has a near unlimited and continuous supply of oxygen. Concentrators have filters which should be exchanged regularly.

In order to buy a new oxygen concentrator, most states require a prescription. Refurbished concentrators can be acquired without a prescription.

Oxygen compressors are a great solution for people using ozone at home for non-invasive applications like insufflations, ozone saunas, or to ozonate water.

Oxygen tanks can be either medical (CGA 870), industrial (CGA 540), ultra high purity (CGA 540), or pre-filled (O2Ready).

The best option for home ozone users are ultra high purity, scientific grade oxygen tanks. They contain oxygen of 99.994% content which makes the gas of higher quality than medical oxygen. They do not require a prescription or license, and come with a certificate which proves that each batch has been tested.

Ultra high purity oxygen tanks can be acquired at Airgas. They come in CGA 540 bottles and require CGA 549 low flow regulators.

Filled medical tanks can be ordered at omssupply.com without a prescription and are the second best option after ultra high purity oxygen.

Having a filled tank at home comes with some risks: the gas inside the cylinder is under extreme pressure. A mishandling could turn it to a missile and hurt humans and damage property. Consequently, it is of utmost importance to secure an O2 tank by keeping it in a cart, or bolt it to a wall, keep it out of the reach of children and away from heat sources.

A tank needs to be regularly inspected to make sure the valve is still intact.

It does not consume electricity, does not create noise, but requires regular refills.
