Disconnect the electricity supply before getting started. Clean the outlet channel first by removing the dust and debris. A dry, soft-bristled brush will be helpful in this regard. Remember, soft not anything rough. Going rough could do some serious damage.

Open the front grill according to the manual, and see if it requires any deep wash. If so, try some warm or soapy water, should the manual allows.

Some device comes with washable pre and a HEPA filter. If yours one happen to be that kind, apply only water. If things seem really messy, soak it in warm water for a while and clean. Let it dry properly afterwards. For non-washable, a vacuum cleaner will be handy.

Place the filters inside and setup your device. Use dry clean cloth to wipe out the outer surface. Your device is cleaned and ready for next use.
