Wildfire smoke doesn't stop at your front door
During US smoke events, indoor PM2.5 routinely tracks 50-80% of outdoor levels within hours. Closing the windows slows it down. It does not stop it.
Wildfire smoke is not ordinary dust. Burning forests, homes and vehicles release ultrafine soot alongside benzene, formaldehyde and acrolein — particles small enough to cross into your bloodstream and reach your brain.
What's in the smoke you're breathing

“Air is a continuous biological signal to the body, and most indoor environments carry far more particulate load than we realize. Lichen Air uses 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.”
