the loose plug caused by the movement of the purifier may affect the
energizing; Secondly, check whether the air inlet grill and air outlet grill of
the purifier are assembled properly. This appliance is provided with a
disassembly protection function. If the air inlet grill and air outlet grill are
not assembled properly, the product cannot work.
Firstly, check whether the foreign bodies block the air inlet grill and air
outlet grill; if any, remove those foreign bodies; Then, check whether
the Pre-Filter becomes dirty or reaches the end of its service life; if any,
clean the Pre-Filter; Finally, check whether the HEPA filter is full of dust

When the appliance is operated for the first time, it smells slightly plastic,
which is normal; If this appliance works in places (like smoking area or
rotisserie, etc.) with strong smell for a long time, you need to change the
filter element frequently and reset it. Check whether the air inlet/outlet
grill and Pre-Filter are full of dust or dirt; if any, maintain the appliance
and clean the dust and dirt on the air inlet/outlet grill and Pre-Filter.
Yes, tilt the machine at a small angle and pull them out with a little effort.
If not, try to pull the wheels out while rotating them.
The wet environment has a greater impact on the filter element, and the
mist produced by the ultrasonic humidifier may cause abnormality in
the PM2.5 detection of this appliance, so that simultaneous operation is
avoided as much as possible.
