Your HVAC system keeps you warm during the cold season and cools during the hot summer. It also keeps your indoor air free from pollen, dust, pet dander, and other small particles. The HVAC system removes these small particles using its air filters, but did you know there are different types of HVAC filters?
Consulting with an HVAC contractor can provide insights into the best filters for your specific system based on its requirements and your indoor air quality needs. Read on to understand the types of HVAC filters that are most suitable for your HVAC system.
Mechanical Air Filters
The most common type of air filter used in most HVAC systems is the mechanical air filter. This type of HVAC filter traps small particles and debris in indoor space using synthetic fibers. Often, the synthetic fiber is folded or pleated to increase its filtering capacity and its surface area. If you are looking for the most efficient mechanical air filter, look out for one with a high Minimum Efficiency Reporting Value (MERV).
MERV ratings range from 1 to 16, and the higher the rating, the more likely the mechanical filter will trap the smallest particles. However, a higher rating also means that your mechanical air filter will experience more airflow resistance, which will strain the HVAC system.
Fiberglass Air Filters
Fiberglass air filters are disposable, which also means they are the least expensive. They are most suitable for keeping large dust particles and debris out of the HVAC system, but they do a poor job of filtering out smaller contaminant particles. Usually, a fiberglass air filter has a MERV rating of 4.
Pleated Air Filters
Pleated air filters are a type of HVAC air filter made from polyester or cotton folds. These materials explain why pleated air filters are more costly compared to fiberglass filters. However, pleated air filters are worth their price as they are the most effective in filtering smaller dust particles and other elements, like pet dander, mold spores, and pollen—the more wrinkles, the more effective the filtration capacity. Pleated air filters usually have MERV ratings ranging from 5 to 8.
Ultraviolet (UV) Filters
UV filters are usually built into the HVAC system, and they use ultraviolet light to kill viruses, bacteria, and other microorganisms floating in the air indoors. Unfortunately, UV filters will do a poor job of filtering out dust, pet dander, and other small particles from the air, leaving you with great concerns for the quality of air in your indoor space.
