What is a furnace filter?

A furnace filter is an essential component of a heating or cooling system that helps to trap and remove particles, dust, and other contaminants from the air before it is circulated throughout a home or building.

Furnace filters come in various types, including disposable filters, washable filters, electrostatic filters, and HEPA filters. Disposable filters need to be replaced regularly, while washable filters can be cleaned and reused. Electrostatic filters use static electricity to attract and capture particles, while HEPA filters are highly efficient at trapping very small particles, such as allergens and pollutants.

It is important to select the right size and type of furnace filter for your specific heating or cooling system to ensure effective filtration and optimal performance. Regularly changing or cleaning the furnace filter is also important to maintain good indoor air quality and extend the lifespan of the heating or cooling system.
