Third-Party Verified Performance
“Air is a continuous biological signal to the body, and most indoor environments carry far more particulate load than we realize. Lichen Air uses hospital-grade HEPA-14 filtration at a level that meaningfully reduces that burden. I’ve never experienced indoor air this clean. It’s not just noticeable, it’s foundational. This is the highest level of air quality I’ve seen made practical for the home.”

The Air In Your Home Could be 5x Dirtier Than What's Outside
The Air In Your Home Could Be 5× Dirtier Than What's Outside
Everyday activities — cooking, cleaning, candles, even furniture — release ultrafine particles that linger for hours.
Add mold, pet dander, and city pollution, and your home becomes a hidden source of fatigue and inflammation.
We breathe 20,000 times a day, and each breath impacts how we think, sleep, and feel — yet most purifiers barely touch the problem.
