You know it’s important to change your HVAC air filter for many reasons. Air filters capture dirt and debris that would build up on HVAC system parts. Filters capture particulates that are harmful for your health. Furthermore, filters will help your AC run more efficiently this summer — but which HVAC filters should you choose? What follows are popular filter types that can help you select the right one for your needs.
HVAC Filter Types: Fiberglass Air Filters
Fiberglass air filters are old-school filters that are usually blue in color. Fiberglass air filters are disposable and last about one month. Fiberglass filters don’t offer the best protection for HVAC equipment when it comes to dirt buildup on equipment, nor for energy efficiency. As dirt builds up on coils and the blower, efficiency is reduced. Therefore, fiberglass HVAC filter types shouldn’t be used.
HVAC Filter Types: Pleated Filter
Pleated HVAC filters offer a larger media surface than flat filters. This allows pleated filters to capture more particulates and contaminants, and it gives them a higher Minimum Efficiency Reporting Value (MERV) rating, which runs from 1 to 20, with 20 being the most efficient filter. Pleated filters often have MERV ratings of between 8 and 13. Pleated filters with MERV 13 can remove viruses, bacteria, mold spores, smoke, and many other contaminants from indoor air. Pleated filters are a great choice for most homeowners.
HVAC Filter Types: Washable Electrostatic Filters
Electrostatic filters are a reusable filter system that can be washed. Electrostatic filters are a metal-frame unit installed in the HVAC system that use electrostatic attraction to remove airborne particles from the air. In addition to being washable and reusable, another advantage to electrostatic filters is their longevity. They may be used for several years before they need to be replaced. When washing the metal plates of these HVAC filter types, be sure to let them dry completely before reinserting them.
