What does "medical ozone" mean, and why do some sites use the term?

The definition we publish

The term medical ozone refers to ozone created from a medical oxygen source. If pure oxygen is not used, impurities pass through the ozone generator too. Our instruction is to always use an ozone sauna that creates ozone from a medical oxygen source.

Why an oxygen feed rather than room air

An ozone generator does not filter anything. It applies a high-voltage charge — normally a corona discharge, a cold plasma that splits O2 molecules so their fragments form O3 — to whatever gas passes through, so whatever is in the feed gas ends up in the output. Air is mostly nitrogen, so an air-fed generator also produces nitrogen oxides. A concentrated oxygen feed removes most of that variable.

Two practical consequences follow:

• Every model we make ships with a medical oxygen concentrator rather than leaving the feed gas to the buyer. The units we supply are 5 l/min at 93% purity, plus or minus 3%.
• Published output ratings only mean anything against a defined feed gas. A generator run on room air is not producing the same output.

It also implies materials

Ozone attacks most materials it contacts, so the gas path has to be ozone-resistant rather than natural rubber, latex or nylon. Ours uses 304 and 316 stainless steel and silicone. The same principle separates a purpose-built device from an improvised one.

What the term describes

“Medical ozone” describes how the gas is made. On its own it is not a statement about regulatory approval, clinical indication or licensing in your market. The useful specifics are the materials: 304 and 316 stainless steel and silicone.

We sell our ozone saunas as wellness equipment, not medical devices. Regulation of ozone therapy itself still differs between countries.
