The purifier is not working

Firstly, check whether the power cord is plugged 

into the power socket, 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 machine cannot work.

The purifier has a small amount

of air and is noisy

Firstly, check whether the foreign matters block 

the air inlet grill and air outlet grill. If any, remove 

those foreign matters;

or reaches the end of its service life; and clean the 

Pre-Filter;

Finally, check whether the HEPA Filter is full of 

dust or reaches the end of its service life. This 

time the replacement

of the HEPA Filter is required.

The air outlet smells odorous

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
