A replaceable device designed to remove dust, pollen or other foreign matter from the air passing through it.

It is designed to fit into air conditioners, ventilation systems and hot air furnaces. It may have facilities for radio frequency/electromagnetic interference shielding. The filter may be cleaned by the use of compressed air, blown through the filter element, or by using water and a suitable detergent for cleaning purposes which would extend the life of the filter.
