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 early effect filter; Finally, check whether the HEPA Filter is full

the composite HEPA Filter is required.
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.

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.
