Therasage TheraO3 Ozone Module Ozone & Ion Generator

TheraO3 Ozone Module is a portable, multi-purpose ozone and ion device. Its core advantage is portability: a rechargeable 18650 lithium battery delivers up to 8 hours of continuous use, with a compact 10-ounce form factor that fits easily in a hand or bag.

Inside a Therasage infrared sauna, the module amplifies ozone absorption through skin by up to 8-10x compared to ambient breathing. The heat-opened pores combined with direct ozone output produces a far stronger session than sauna alone.

Outside the sauna, the module switches to air-purification mode for cars, hotel rooms, planes, or offices. A second mode activates a built-in negative-ion generator for mood, sleep, and air-quality support without ozone output.

If you want a portable wellness tool that doubles as travel-air defense, the TheraO3 Module is built for that.
