  2. Remove Filters

    There will be two curved mesh filters under the cover.  They are set in behind a plastic tab.  Push up and over the tab then gently pull downwards.  They should slide out.

  3. Wash and Dry

    In a large sink or outside under a tap, run water over the filter while dabbing gently with a sponge on each side.  The mesh can be easy to damage so you will need to take care.  Leave to air dry.

If your air conditioner is in a kitchen and the filters feel greasy you may need to use dish washing detergent mixed in warm water.  Gently dab it onto the filter with a sponge then wash off with clean warm water.
