After a Kuwait dust storm, indoor air can stay bad for days while everyone assumes closing the windows solved it. This reads PM2.5, PM10, CO2, temperature and humidity on one screen, so you can see when to run the purifier and when to open up. During a March storm we measured indoor PM2.5 at six times the calm-day level with every window shut.

Questions people ask
What PM2.5 number is bad?
Above 35 µg/m³ is where most guidance says act. In a Kuwait dust storm we've measured indoor readings far past that.
Does high CO2 matter at home?
In a closed bedroom with the AC recirculating it climbs overnight, and that's the stuffy-headache feeling in the morning.
