Understanding the Different Types of Air Filters

Changing out filters is an essential part of any air conditioner repair and maintenance plan. Experts recommend changing or cleaning your HVAC filters at least once every 90 days; however, depending on your usage, you may need to do it as often as once a month. With the need for new filters so great, it’s important to understand the various different types of filters available so you can be sure to always choose the right one.

Let our HVAC experts at A STAR Air Conditioning and Heating teach you about some the basic types of air filters to help you make the right choice for your own heating and cooling system.

Reusable Air Filters

The advantage of reusable air filters is that they can save you from having to buy new filters, which in turn saves you money. Be wary, however, of using newly-washed filters in your system, as the high moisture content in damp filters could increase your indoor humidity, as well as lead to mold and mildew growth. Contact your cooling and heating company for dehumidifier options to help minimize this problem.

HEPA Filters

A high-efficiency particulate air (HEPA) filter is one of the best filter options available today. These filters are often utilized in commercial and industrial settings, but more and more homeowners are finding reasons for their residential use. Boasting some of the highest MERV ratings in the industry (a measure of filter efficiency), these filters are effective at trapping bacteria and viruses and removing them from air circulation. Be sure to first consult the manufacturer’s instructions, however, as well as a qualified HVAC technician, as some systems aren’t rated for filters with such high MERV ratings.

Fiberglass and Other Media Filters

For many homes, the low MERV ratings of fiberglass and similar types of filters are more than sufficient for their needs. Despite their comparatively low rate of performance, they beat most other types of filters in terms of affordability and availability. Fiberglass filters are by far the most common kind found in many local home improvement stores. Their versatility lends itself well to a wide variety of applications, and they can be used for heat pump repair, air registers, furnaces and of course air conditioners.
