Requires simple replacement only once or twice per year, depending on your usage. No moving parts to break.

The filter media is not cleanable and must be replaced a minimum of twice a year, once in the heating season and again in the cooling season. If your home only has heating, the filter must be replaced annually. Please note, if you have shedding pets, or live in a dusty environment, you will need to replace the filter media more often.
