What a furnace filter does

Furnace filter protects the furnace, specifically the blower fan from all the dust and debris that is pulled there by the return vent.

Although furnace filter does help to keep air in the house clean, however it is not its direct purpose.

The main task of the furnace filter is to catch the dust that is traveling in the air flow and to keep it out of your home and out of the furnace.

While it catches all the dust and debris , they of course get collected on the filter by itself and that’s why it is highly recommended to change filter on a regular basis, monthly could be ideal.

Dusted and clogged furnace filter will not be able to catch any more dust particles and will not allow air conditioner and furnace work properly, it can even cause air pollution.
