With all the options on the market, do you know what type of HVAC air filter to buy?
Air filters for your heating and air conditioning system are essential for several reasons. First, they protect your HVAC from dust and debris that can damage the moving parts. Second, they help keep your indoor air clean when they trap airborne pollutants. When it comes to air filters, the question for most homeowners is, what type should I buy for my home? Here’s a quick guide to help you decide.
Pleated
Pleated filters are the most common for home HVAC systems. The pleats help increase surface area to trap small particles, including mold, dander, pollen, dust, dust mites, and household chemicals. They’re made of polyester or cotton, so they’re usually reasonably priced and you can change them frequently without it taking a toll on your wallet.
HEPA
Most people with allergies know about HEPA filters. They’re commonly used in vacuums, HVAC systems, and air purifiers and are ideal for use in hospitals, schools, and homes. They trap smaller particles than pleated filters with effectiveness ratings of 99.9%. As a result, they’re great at reducing irritants and contaminants in the air that cause allergies or asthma symptoms, such as mold, dust, pollen, and even bacteria.
Fiberglass
Fiberglass filters are the least expensive of the three types we’re mentioning. Because the material is more porous than the other filters, more particles can get through, which can put your HVAC system at risk and won’t work as well to improve your indoor air quality. However, they are inexpensive to produce and, as a result, aren’t as effective as pleated or HEPA. A clean fiberglass filter is still better than a dirty pleated filter if your budget is tight.
