I bought 4 meanwhile, one for each room, after being very satisfied with the results, I also always double check with two different PM2.5 meters, which confirm the speed of cleaning the air.

This is very misleading and makes the auto mode useless (if it’s not useless already with the problems mentioned earlier). Or is it really possible that my ultrasonic humidifier emits that much of “particles” which count as pm2.5? It doesn’t look to be dirty, I tried… Read more »
