Choosing between the various HVAC air filter types can be a difficult task. There are many different types of AC filters on the market, each with its features. As a result, it’s vital to consider your home’s requirements and MERV recommendations. If any of your family members suffer from allergies, choose a filter with a higher MERV rating.

Fiberglass Air Filter

UV Light Air Filter

However, they can potentially convert oxygen molecules into ozone molecules, which can cause coughing and chest pains in small amounts.

Electrostatic Filters

HEPA Filter

A high-efficiency particulate air (HEPA) filter is one of the most efficient HVAC filters. AC service in Whittier CA, experts suggest that they can remove up to 99.97 per cent of pollutants and allergens from the air. These filters are popular among people who suffer from allergies to air conditioners or other respiratory issues.

Washable AC Filter
