healthy air protect lock
This air purier is equipped with a
lter replacement indicator to make
sure that the air purication lter is
in optimal condition when the air
purier is operating. When the lters
need to be replaced, the lter code
displays on the screen and the lter

If the lters are not replaced in time,

and automatically lock to protect
the air quality in the room. Replace
the lters as soon as possible
according to the lter code.
