How Often Should HVAC Filters Be Changed?

FST Air Filters are made in the USA using high quality materials, and are long lasting so you can breathe better. All our HVAC filter sizes are pleated to provide more surface area to trap particles, and the frames stay rigid through temperature and humidity changes.
Replacing your air filter is an easy, inexpensive step to improve your indoor air quality and extend the life of your heating or cooling system.
