Furnace Air Filters: What's The Big Deal?

Furnace air filters are often overlooked when considering a home's overall indoor air quality, but this is a mistake a homeowner should quickly learn to rectify. Not only will your furnace run more efficiently with a clean, high-quality filter, a good filter will help you maintain a clean, dust-free environment. The best filters of this type use electrostatic charges (static electricity) to pull harmful particles from the air, before they reach your lungs.

How do these filters work?

Most furnace filters include a layer of static-prone fibers resembling a maze; when air flows through the maze, an electrostatic charge is generated. We've all seen the way static electricity can cause fabrics to cling together, or make our hair snap and crackle on a dry day as we comb it. Similarly, tiny particles of dust, allergens, pet dander, and the like are drawn to the static on the air filter, and stay there until washed away during cleaning.

How do I know which electrostatic filter is best for my furnace?

That's why we're here. Our goal is to make the search for top-notch filters as easy as it can be. Our merchants will provide you with air quality information on all types of High Energy Particulate Air (a.k.a. HEPA) filters for every type of furnace out there to help remove dust, soot, pollen, and other tiny particles from your home's air before recirculating it. The best HEPA filters are washable and can be reused for over a year.
