Bought an air purifier, it was supposed to have a sensor and you could put it on auto.
It's clearly wrong lol, PM2.5 shows 001 which is unrealistically clean and it says it's 27c in the room which is just impossible I even think it's a bit cold atm.
Even tried spraying some deodorant in front of it and nothing, it only changed to like 005 and went back to 001 after a few seconds after I opened and closed the door.

I looked into it and saw someone else from Sweden too who had contacted support and they said that it's basically working as intended, and that the sensors just aren't very sensitive they're designed for China and other countries with poor air quality...
I feel a bit scammed lol.
It's a good purifier it's just sad that the sensor doesn't work and you have to use the app to manually change the speed.
But I dunno if I even believe the explanation because the temp and humidity is very clearly wrong.
I am pondering whether to return it and get something else or just keep it, the control thing is really my only issue outside of that and dunno if I can even get one with a sensor for auto-mode for that price I got it on when it was on sale.
