If the Wyze air filter can detect when a filter needs to be changed, why can’t it detect when a new filter is installed?
The purifier calculates the filters remaining life based on time, fan setting, and AQI. It cant actually check how dirty the filter is.
When replacing the filter, you can reset it with:
Press and hold the Power button and Auto Mode button until the air purifier beeps and the Filter Replacement Indicator starts flashing. The Filter Replacement Indicator will stop flashing to indicate that it has been reset.

What is the life of the filter ? I activated my air Purifier on August 11, 2022. Its in a bedroom, no smoke, says clean air in history for last two months. runs on auto. Today its says i need to replace soon. Down to 5%. How can this only last two months?

Great advice rulwiz 
Yea, generally when it tells you to replace the filter that’s just for best performance. If you know it didn’t get too much use, then you can just clean it out and reset

Also, the take the filter out and vacuum it tip isn’t just for rare use, You want to do that at least every 2 months, to remove the fur and fuzz and stuff that will clog it up. It’s on page 15 of the guide that comes with it.

I’m having the same issue. My AQI is normally below 10 and being on Auto the fan speed is mostly on low. So with these conditions a two month filter life is ridiculous, considering how expensive they are. And the fact that they can’t be cleaned with water and are thrown away just adds more trash to the landfill.
I ordered my first back in April in the preorder, scheduled for sleep mode 9 pm to 5 am, auto outside that. After the first few days aqi is usually down into the single digits, unless something like bacon is being cooked. I take out and vacuum off the filter when I remember to every couple of months, because that was somewhere in the instructions. I only got the replace filter light coming on a week or 2 ago.
I never saw anything in the instructions saying to vacuum the filter.
on vacuuming the filter, it’s on page 15 of the “quick start guide” that comes with it:
Use the brush or hose attachment of a vacuum cleaner to remove dust, hair, lint and other particles from the outside of the filter. Never use water… … We recommend cleaning the filter every 2 months.

I was referring to the paper copy that came with mine. Apparently there are at least 2 versions of the guide
I know its been a couple years and maybe someone already told you or you know already, but if you have a humidifier in your room, it will cause your air purifier to run on high. Air purifiers and humidifiers don’t mix. At night I turn my purifier to sleep mode. It sits in the living room and my humidifier is in my bedroom. If I keep the purifier on at night, it detects the humidity and starts to ramp up.
