Mold spores are in your air. We fix that.
You can't see them, but you might feel them. The stuffy mornings. The lingering must. Air that never quite feels clean. The Air Purifier Max is lab tested to capture 99.95% of common household mold spores in 60 minutes. Independently verified. Not a claim, a result.

PURIFIER
99.95% of household mold. Gone in 60 minutes.
We put the Max in a sealed chamber, filled the air with Aspergillus (the most common household mold), and let it run one cycle. Sixty minutes later, 99.95% of the spores were gone. Tested at an independent lab, not on our own bench.*
One unit. The whole floor, up to 1950 sq ft.
Most purifiers guard one small room and quit. The Max is AHAM certified for spaces up to 1,950 sq ft. Think the open-plan living room, the studio, the primary bedroom. It cleans air that leaves other units running flat out and still falling short.
The only purifier designed with real bamboo
Most purifiers look like equipment. The Max is finished with a real bamboo base that's warm, renewable, and made to be seen. The rare piece of home tech you'll set out in the open on purpose.

You won't hear it work.
Two ways to sleep on it. Whisper mode drops to just 16 dB, quieter than a whisper and all but silent through the night. White noise mode holds a soft, steady hum for anyone who sleeps better with a little sound in the room.
You've been living with it. And calling it fine.
The stuffy mornings. The musty smell that never fully leaves the closet. The window you keep shut in spring. You've cracked the window, run the fan, wiped down the sills. Small fixes. Twelve small fixes that never quite added up.
It wasn't you. Standard filters simply miss mold. Spores run 2 to 20 microns and slip right through. HEPA 13 captures 99.95% of particles down to 0.3 microns. Smaller than any spore. Nothing to slip through.
