The Half of the System Nobody Talks About
Ozonating water creates two outputs: ozonated water, and excess ozone gas. Water treatment plants solve the second output with destruct units; most home setups ignore it entirely. This guide explains what an ozone destructor is, how industrial off-gas control works, and what the same job looks like at kitchen scale — so the gas you didn’t dissolve never becomes the air you breathe.
Bubbling ozone through a diffuser dissolves only about 15% of the gas — contact time is short and bubbles rise fast. The other ~85% breaks the surface and keeps rising, into the room. Every serious ozone system, from municipal plants to a mason jar on a counter, has to answer the same question: what happens to the gas that didn’t dissolve?
Municipal and industrial ozone systems capture off-gas from sealed contact tanks and run it through ozone destruct units — catalytic beds (or heat) that convert O₃ back to ordinary O₂ before venting. Engineered, monitored, and sized for grams-per-hour flows.
The same job at household scale: seal the vessel and route the rising off-gas through a medium that destroys ozone before the air leaves the jar. That is precisely what the Tri-Oxy® REFRESH degassing kit does — a glass jar, a diffuser, and a screw-on cap whose degassing material neutralizes the excess gas at the source.
When I started making ozonated water in the late 1990s, nobody talked about the gas above the jar — you smelled it, your throat caught it, and everyone pretended that was normal. My nuclear background would not let me pretend. If a treatment plant would never vent raw ozone, why should a kitchen? The REFRESH cap exists because the off-gas is not a side effect to tolerate — it is half the system, and it deserved engineering.

The Tri-Oxy® REFRESH kit destroys the excess gas right at the jar — so everything ozone offers ends up in the water, and nothing ends up in your lungs.
