Clean-air buying guides
Picked by tested clean-air delivery rate (CADR), noise and running cost, from independent test labels. No brand pays to be listed.
Air purifiers that keep up with wildfire smoke and winter smog, ranked by verified smoke CADR, with the room each one clears on a smoky day.
Good HEPA air purifiers under $200 at the makers' own prices, compared on verified clean air, room size and what the filters cost each year.

Frequently asked
Airleaf measures 1 city in Saint Helena. Jamestown reads AQI 70 right now.
Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
