Method for cleaning the air filter
a. The air filter can prevent the dust or other particles from
entering the unit. If the filter is blocked, the unit will not work
well. Clean the filter every two weeks when you use it regularly.

filter often.
c. Replace the filter if it is too dusty to clean (the replaceable air
filter is an optional fitting).
1. Open the unit
Open the unit by placing your fingers under the notches on the sides
of the cover and moving the cover outwards. Open the cover fully to
allow sufficient room to remove the filter.

2. Dismantle the filter
Gently push the filter upwards to release the notches, then pull the
filter out.
