The ability of the filters to grab these fine particulates also improve your home’s indoor air quality. Selecting the right air filter is critical for keeping your home comfortable. With so many air filter choices on the market, that selection can be difficult.

All air filters have an efficiency rating known as the minimum efficiency reporting value, or MERV. The higher the MERV rating, the more efficient the ability of the air filter to capture microscopic particulates.

Which Air Filter Is Right for Your Sarasota Home?

  • Fiberglass air filters are the most basic model on the market. These filters are made of a web of fiberglass fibers in a cardboard frame that measures about 1 inch in thickness. They primarily protect the HVAC equipment and don’t improve air quality. They usually have a MERV of 1 to 4.
  • Pleated air filters are the next step up. These filters are made of pleated cotton or paper held in a cardboard frame. They can capture up to 45 percent of the air pollutants in your home. They normally have a MERV of between 8 and 13.
  • High-efficiency air filters are made of layers of folded paper or cotton fibers. They can remove up to 85 percent of air pollutants and have a MERV of between 14 and 16. Unless used in a special air cleaning system, these filters aren’t usually seen in residential applications.

It’s critical that any air filter¬†used in a system doesn’t restrict airflow. Poor airflow can strain the HVAC system, causing higher energy bills and more repair costs.
