If you’re looking for an air purifier, the Honeywell HPA300 ($200) is more than enough four our three bedroom house (despite the 465sq ft rating).

I want to be able to recommend the Bissell Air400, as it is quieter, has a built in PM 2.5 meter, auto adjusts to pollutants, and the filter works at least as well.

Unfortunately, it randomly turns itself off. This seems to be a design flaw, as many other people report the same thing. Also, it doesn’t seem to use a PID control loop to set fan speed, so the automatic speed controller sets itself far too low for our house. On the bright side, it is frequently on sale for 50%+ off, since it has a terrible reputation.

In practice, I leave the honeywell on, and use the bissell if there’s a problem (cooking smoke, allergies, wildfires, etc). In tandem, the two are able to lower PM 2.5 by over 90%, which is more than enough for fire season.

Edit: In hindsight, I would have bought the HPA 300, and a standalone sensor like the ones from purple air.

Do you have something that measures the PM level?
