2022 Guide, Different Types of Furnace Filters

Looking for the right furnace filter for your house? Check out different types of furnace filters and choose the right one for your system.


Furnace filters are a very crucial element of your heating and cooling system. This element of your house improves the air quality and protects your HVAC unit from airborne contaminants. However, different air filters work differently in trapping microscopic particles and pollutants. This essential guide will help you choose the right one from different furnace filters for your equipment. Additionally, we will explore how and when to change the filter to enjoy the best indoor air.

Different Types of Furnace Filters

Fiberglass Air Filters

If you’re looking for the cheapest air filter for your system, you can purchase fiberglass air filters of different layers. A metal frame supports several layers. Though they are famous for cheap rates, they could be more effective in trapping contaminants in a more extensive area. Another issue is that these air filters are less durable, and you need to replace them more frequently than other air filters.

HEPA Air Filters

HEPA stands for High-efficiency Particulate Air. It is good to choose HEPA filters if you are concerned about getting the best indoor air quality. No other air filters are as effective as HEPA filters in trapping almost all the airborne contaminants in your house. As they are the most efficient air filter type to catch the maximum microscopic allergens, you will have to spend a high price to purchase them. If you have family members with breathing difficulties, asthma, allergy, or respiratory symptoms, consider buying these filters to get the best output.

Pleated Air Filters

Pleated air filters are a better option than fiberglass 12x12x1 air filters as they are highly effective in catching microscopic allergens, even in larger areas. Furthermore, these air filters also have high airflow resistance. Therefore, if your pleated air filter has more pleats, it will clean the air more efficiently.

Activated Carbon Filters

Another popular type of furnace filter is an activated carbon filter. These can catch the maximum number of particles but are more commonly used due to their effectiveness in removing odors from your place.

UV Filters

UV filters are effective in trapping bacteria, viruses, and microbes. Still, you shouldn’t choose them if you are looking for an ideal air filter to trap a considerable number of airborne contaminants from your home. They are not as effective as other furnace filters, but you can install them to protect your family members with poor immune systems.

Reusable Air Filters

If you are concerned about your budget, pick a reusable air filter for your house. Reusable air filters are made of plastic materials that help them to be more durable than many other furnace filters, but they are not an ideal pick for an excellent air filtration service.
