6  Replacing the 

air purification 

filters

Understanding the 

healthy air protect lock

This air purifier is equipped with a 
filter replacement indicator to make 
sure that the air purification filter is 
in optimal condition when the air 
purifier is operating. When the filters 
need to be replaced, the filter code 
displays on the screen and the filter 
replacement alert (   ) lights up red.
If the filters are not replaced in time, 
the air purifier will stop operating 
and automatically lock to protect 
the air quality in the room. Replace 
the filters as soon as possible 
according to the filter code.

Replacing the filters

• 

The air purification filters are not 
washable or reusable.

• 

Always turn off the air purifier 
and unplug from the electrical 
outlet before replacing the 
filters.

• 

Do not clean the filters with a 
vacuum.

• 

If the pre-filter is damaged, 
worn or broken, do not use.
