What to do if PM2.5 readings of the Xiaomi Smart Pet Care Air Purifier are abnormal or inaccurate?
When encountering inaccurate or abnormal PM2.5 readings, check if the particle sensor cover on the back of the device is dirty or clogged. If it is, use a non-sharp tool to open the particle sensor cover and clean it with an air blower or a hair dryer (do not use hot air). Gently brush the particle sensor cover with a used toothbrush dipped in clean water. After cleaning and drying, reinstall the door and test.
If multiple air purifiers show different values in the same environment, this could be due to factors like different heights, which can cause different readings. You can test them in sleep mode and with different levels of smoke. If the error increases linearly, it indicates a malfunction of the particle sensor. If the error stays within a certain range, it is normal.
