HVAC filters are essential to keeping a clean and healthy indoor environment. Experts recommend cleaning or changing them every few months to ensure dirt or dust won’t build up and inhibit function.

4 Types of HVAC Filters

When shopping for HVAC filters, you’ll likely find a number of options to choose from in varying types. sizes and efficiency ratings. If you’re thinking of upgrading to a more efficient filter, here’s a simple guide to four types of HVAC filters you’ll find on the market. Air Pro Heating & Air Conditioning Inc., a trusted provider of heating and cooling services, discusses the features of these HVAC filters to help you learn more about your choices.

HEPA Filter

HEPA filters offer the highest level of protection against a variety of airborne particles. They have the capacity to trap particles that are as small as 0.3 microns and catch 99.97% of airborne particles. In addition, HEPA filters have a MERV rating of between 17 and 20.

This type of filter, however, usually doesn’t fit residential HVAC systems that have sizing and airflow restrictions to consider. If you’re keen on getting HEPA filters for your home, modifications will have to be made by an HVAC contractor.

Reusable Air Filters

Reusable are filters are washable filters that can simply be cleaned up and used again. This type of filter is typically more expensive than the disposable kind, and have a low MERV rating of between one and four. This makes reusable air filters prone to mold or mildew growth.

Flat-Paneled Fiberglass Filters

This type of filter is disposable, and is layered with fiberglass and a metal-reinforcing grate. It also has a low MERV rating, so it won’t do much for your home when it comes to air purification.

Pleated Media Filter

These filters are disposable. Typically, they have a MERV rating of between five and 13. However, pleated media filters also have high-efficiency versions that have a MERV rating between 14 and 16. The design of this type of filter is intended to increase the surface area, which improves its filtration efficiency as well.
