What Are the Different Types of HVAC Filters?

HVAC Filters

As with many things in life, your HVAC system has many different filter options to choose from. Understanding the different types of filters available and how they work is necessary for choosing the right one to fit your needs. Here are some of the most common options that you'll encounter at the store:

Fiberglass Air Filters

These filters are made of fiberglass screening that works to filter the air going through the ductwork in your home. While these filters are great for filtering out dirt and larger particles, they fall shy of adequate filtering of things like bacteria, pet dander, and pollen. If you or your family members have allergies, then you should consider a higher quality filter. Fiberglass filters tend to be the most inexpensive filter on the market.

Pleated Filters

These tend to be made of cotton folds or polyester fabrics. The pleated fashion of this filter allows it to filter dust and smaller pollutants. For those who have respiratory problems, this type of filter is recommended because it filters out pollen, pet dander, and bacteria throughout the air in your home. Pleated filters will cost more than traditional fiberglass air filters but they allow for more filtering power.

Washable Air Filters

Most HVAC filters are meant to be used once and thrown out when they reach the end of their lifespan. Washable air filters are meant to be cleaned when they become full and reused in the future. These can be convenient in the sense of not having to pay for a new HVAC filter every two to three months. However, you have to be careful that your filter is appropriately cleaned and dries out fully before installing it. Any excess water left in these filters can cause bacterial buildup and/or mold growth in your system.

HEPA Filters

At the top end of HVAC filters come in the HEPA filter. This works to filter out 99.97 percent of contaminants that lie in the air circulating throughout your home or office. This type of filter is highly recommended by the United States Department Of Energy for those who are dealing with severe allergies and respiratory problems. HEPA filters are the most expensive HVAC filters on the market because they do provide the highest filtering possible for your HVAC system.
