This replacement filter works just fine with my Xiaomi Compact 4 Smart Air Purifier
works just fine with my Xiaomi Compact 4 Smart Air Purifier. For those who could not get it to work below are the instructions. Don't forget step 6! 1. unplug the air purifier 2. turn the whole air purifier upside down 3. turn the handle you see counterclockwise to take out the old filter and clean out any visible debris 4. insert the new filter turn it clockwise to lock it in 5. turn the whole air purifier right side up 6. plug it back in BUT before turning it on press and hold the power button for seven seconds to reset the filter. 7. you should be all set to turn it on now. That's it! I verified via my app that the filter was now showing 100%
