Increase the frequency of cleaning if the unit is installed in a
room where the air is extremely contaminated.
(As a yardstick for yourself, consider cleaning the filter once a
half year.)
If dirt becomes impossible to clean, change the air filter. (Air filter
for exchange is optional.)

Grip the suction grill on one side, and open by pulling toward
yourself while holding it up.
