Of the many components that influence the effectiveness of your air conditioner, few are more frequently overlooked than air filters. But, as the team at Comfort Tech Heating and Air Conditioning in Thomasville, NC, notes, the different types of filters available on the market can affect both your indoor air quality and your unit’s performance.

4 Common Filter Options for Your Air Conditioner

1. Fiberglass Filters

Fiberglass filters remain the most common filter option for residential and commercial air conditioners. These filters are designed using several layers of fiberglass fibers and a reinforced metal grating to trap dust, pollen, and other contaminants. While effective at preventing the circulation of these particles, these filters usually need to be replaced every three months. More frequent replacements may be necessary for individuals who have allergies.

2. Polyester Filters

As with fiberglass, polyester air filters use multiple layers to trap dust and other particles. However, polyester filters tend to offer higher dust trapping capabilities and airflow resistance, making them a good option for buildings with higher contaminant risk.

3. HEPA Filters

Also known as high-efficiency particulate arrestance filters, a HEPA filter uses a very fine filtration system to meet U.S. Department of Energy standards. Frequently used in aircraft, medical facilities, and motor vehicles, these filters can remove 99.97% of particles larger than 0.3 microns.

4. Washable Filters

While less common than other air conditioner filter options, washable filters are sometimes used for industrial processes that produce a lot of coarse dust. Dust accumulation actually helps these filters become more effective over time.
