Your 101 Guide to Different HVAC Filters

Are your springtime allergies kicking in? The solution to your sneezing and itchy eyes may not be medication—it might be as simple as changing or upgrading your HVAC system’s air filter. Choose from one of the four levels of protection offered by these different filters.

Furnace Air Filter

Fiberglass Filters

The most basic variety of HVAC filter, fiberglass filters are primarily designed to block large dust particles. While they help to slow down HVAC inefficiencies from setting in, they provide minimal protection. However, they’re also the cheapest HVAC filter available, making them the most popular.

Pleated Paper Filters

Pleated filters provided greater protection because they have greater surface area. The folds of a pleated paper filter can trap up to 45% of the dust, allergens, and other particles in the air. According to the American Lung Association , high-efficiency pleated filter models do a better job of trapping the particles that cause asthma and allergies than standard models. Pleated paper filters can last slightly longer than fiberglass filters but can restrict airflow if they get clogged.

Media Filters

Thicker media filters are typically designed for use directly in your furnace or air handler. Like pleated paper filters, media filters are texturized for maximum protection from dust or allergens. These filters are usually around four inches thick, which means that they only need to be replaced two or three times every year.

Electronic Filters

If you’re looking for the most modern solution to poor indoor air quality, an electronic filtration system is your best option. These systems are installed in your HVAC and capture dust, allergens, and other particles as they float by using an electrostatic force. These filters can be cleaned and reused, making it easy to keep your HVAC system clean and efficient throughout the year.
