Hi,
thank you for your work!

I was thinking of buying Xiaomi Air Purifier 2S, but before I decide to buy it I would like to measure air quality in our flat.

Just checked ebay offer and found couple of devices, but I am not sure are they ok or just a waste of money and would like to hear your opinion. Professional devices are just to expensive for me.

Thanks!

The old problem of reverting to auto mode was solved in newer firmware, so the purifier can keep running 24/7 at the level you set it to. So this whole conclusion that it doesnt clean is not valid anymore. The new versions run well, very good bang for buck. 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.

One more interesting thing what I found while using the 2s, which no one seems to have mentioned: Using it together with a (ultrasonic in my case) humidifier in the same room, the pm2.5 readings jump up to 100-120 almost instantly with the humidity increasing – it’s around 120 when the humidity reaches 50-52%. 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 »
