In case you're curious how this does with wildfire smoke -- Oakland 1 bedroom, put a 14"x20" MERV 13 (filtrete blue) filter on a box fan (covering the extra 6" with paper). Had a PMS5003 from adafruit monitoring before and after. In the span of 3 hours indoor PM2.5 dropped from 25 to 5 ug/m3 and has stayed low since. https://imgur.com/IxdxhV2 |
