Air Filters
Air filters should be inspected annually. If a filter is dirty or clogged, first tap it on 
the ground. If the filter is still dirty or clogged, then wash it with warm water and a 
mild detergent. A vacuum cleaner can be used if one is available. If there is no 
facility for washing or vacuuming the air filter, then replace the filter (Comcode

 below for more 
information on air filters and fans.
