Today my Wyze Air Purifier upstairs in my house set to Auto is running very fast and says the AQI is Moderate at 88, with the outdoor pollutants for PM2.5 as unhealthy at 37 ug/m3. Yet, when at the IQAir site for my city it shows the air quality is good with PM2.5 at 7 ug/m3. My area normally has really good air quality due to off shore winds from the ocean. I know at night it’s normal for the air quality to be worse upstarts than downstairs in my house but, not by this drastic of a difference. I unplugged the purifier to reset it and made sure there were no spider webs on the outside of it. Maybe this is just a one off thing but still odd. I know a few years ago when I had it downstairs it started running on high for no apparent reason when the outside air quality was good and nothing had changed on the inside of my house, like cooking bacon or something. I checked all the upstairs rooms, so there wasn’t a fire or anything either. Any thoughts?
Using a Plug-in Air freshener? Someone take a shower? (humidity counts as particles in the air that get detected)
I would try relocating it somewhere else. If you have more than one air purifier, put them near each other and see if they both react the same way.
You could try a factory reset, though it’s possible a hard restart is sufficient (unplug for 10+seconds and then plug it back in).
Try spraying nearby an air freshener or any other kind of spray that disperses in the air and see if it changes the air quality and the fan speed (this is to check if the sensors are properly functional and recognize a change in air quality and react up and then down when it clears).
Those are things I’d consider and try
No air freshener or shower near it. I already did a reset as I said before. Spraying an air freshener near the sensor does make the numbers go up and the fan speed increase, so the unit is working correctly. Not sure what the issue is with it because today it didn’t do a crazy run up like it had.
