Types of Filters for your HVAC System

Let’s just for a second ignore the fact that reusable or “cleanable” HVAC filters exist. Now if we’re talking replaceable filters, like the majority of us have, there are plenty of filter types to discuss. But first off, let’s talk about MERV…

What is the MERV Rating?

Many years ago, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers established a rating system to determine the energy-efficiency and effectiveness of individual filters. This rating system takes into account energy-efficiency, air-quality effectiveness, and the impact of your filter on home health.

So you might assume the higher the MERV, the better the filter, right? Unfortunately, it’s not quite that cut and dry. Many filter types (HEPA, for instance) are impractical or downright unusable for central and heat pump air conditioning. This is because they, frankly, filter too much and constrict air flow, causing a variety of issues that result in air conditioner repair.

What Types of Filters are There?

With the MERV business out of the way, let’s talk materials and types:

  • Fiberglass air filters. These are the most common filter type you’ll see in any given home or apartment. They do a serviceable job at filtering large particles and maintaining your system, but have no impact whatsoever (or at least a negligible one) on air quality. These are often chosen for simplicity, or because of the sheer low-cost involved in utilizing them.
  • Pleated, or polyester filters. While a bit pricier, these filters boast a considerably higher MERV rating (while still being residential system friendly), and will have a noticeable impact on the cleanliness and air quality of your home.
  • HEPA filters. While HEPA filters provide some of the best air quality control and HVAC safety available, they are entirely impractical for residential use. Using a HEPA in your central system is more likely to break something important, and will actually drastically reduce the quality of comfort and cooling in your home. These are generally seen used in large industrial facilities.
