Tri-Oxy® REFRESH Degasser Manual
The Tri-Oxy® REFRESH degasser lets you ozonate water safely by destructing excess ozone gas instead of releasing it into the room. This manual covers assembling the degasser, connecting it to your ozone generator, ozonating water, and caring for the diffuser.

Why degas
What the Tri-Oxy® REFRESH does
When you ozonate water, excess ozone gas bubbles out of the liquid. Because ozone gas should not be inhaled, the Tri-Oxy® REFRESH passes that off-gas through degassing granules that break ozone back down into ordinary oxygen before it reaches the room. The result is a safer way to make ozonated water at home with any compatible ozone generator, such as the Tri-Oxy® FRESH.
Assembly
Set up the degasser
1
Load the degassing granules
Pour degassing granules into the container on top of the pre-installed FDA-approved stainless steel mesh filter, then screw on the cap and leave it in place until it is time to replace the material.
2
Connect the diffuser
Connect the silicone tubing to the FDA-approved degasser diffuser of your choice (0.5 micron or 50–60 micron), then connect the other end of the tube to the male barb fitting on the bottom of the container.
3
Attach to the water jar
Screw the Tri-Oxy® REFRESH assembly onto the glass jar filled with water.
4
Connect the ozone generator
Connect a silicone tube from your ozone generator to the male barb fitting on the top cap.

Operation
Ozonate water and time the run
Turn on the ozone generator to ozonate water or another preferred liquid. Ozonate for approximately 1 minute per ounce of water. If you are using the 0.5 micron diffuser, you can reduce that time by 50%.
Always degas — do not inhale ozone
Run water applications through the degasser so ozone off-gas is destructed rather than released. Ozone gas should not be inhaled.
After use & maintenance
Clear the diffuser and replace the granules on schedule
After each use
When you are done ozonating, empty the liquid, screw the Tri-Oxy® REFRESH assembly back onto the glass jar, and run the ozone generator to blow the water out of the diffuser. Blow out the diffuser with ozone gas (or with your mouth) and let it dry so the pores do not clog.
Replacing the degassing material
Replace the degassing material when it no longer destructs ozone gas. Depending on how often you ozonate water, this can take 5 to 10 years.
Common questions
Frequently asked questions
How long do I ozonate the water?
About 1 minute per ounce of water. With the 0.5 micron diffuser you can cut that time in half.
Which diffuser should I use?
Either the 0.5 micron or the 50–60 micron degasser diffuser. The finer 0.5 micron diffuser dissolves ozone faster, so it needs about half the run time.
How do I keep the diffuser from clogging?
After each use, blow the water out of the diffuser with ozone gas or your mouth and let it dry. This keeps minerals from clogging the pores.
How often do I replace the degassing granules?
Only when they stop destructing ozone gas — typically every 5 to 10 years depending on use.
