and remove the front panel.
2. Pinch the handle under the air filter and make the air filter
arched, remove it from the slot from underside to upside.
3. Clean the filter with warm water. The water
should be below 40 C to prevent distortion of the filter.
4. Rinse off and gently shake off excess water from the
filter. Allow the filter to dry before re-install it. To prevent
distortion of the filter, do not dry it in direct sunlight.
CAUTION

Always keep the top or bottom blades in horizontality. This can
