The EPA says a MERV 13 furnace filter can remove as much as 95% of the particles that pass through it, including wildfire smoke. This can be especially important during smoky periods to remove the fine particle pollution from smoke in your home’s indoor air.
Air filters should be replaced every 60-90 days, or more often if you suffer from allergies or if you have children or pets.
FST Air Filters are made in the USA using high quality materials, and are long lasting so you can breathe better. All filters 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.
