Types of HVAC Filter

The HVAC filters play an important role in your house’s cooling and heating system. That makes sure that the air that you breathe is clean by filtering pet dander, pollen dust, and other harmful particles. If these particles with harmful germs are not filtered, they’ll circulate across your home. The market is filled with many HVAC filter types, and it becomes a challenging task to choose the right option. This article will help you to understand the different air filter types for your HVAC system. So, let’s dive into it.

Air Filter Types HVAC

The efficiency of any HVAC filter is directly proportional to its MERV rating. The efficient filter also protects your HVAC systems from damage by keeping the larger particles away. That’s why using the right type of HVAC filet is important. The following are the most common types of HVAC filters that you can use for your residential places.

Fiberglass Air Filters

If you're on a very tight budget, then a fiberglass filter might suit you the best. This type of fiberglass air filters come with the lowest straining ability and the most affordable prices. As compared to screening pollutants and dust, fiberglass air filters work better to protect the AC system. In simple words, you most probably will be prone to respiratory issues while using this type of air filter.

Pleated Filters

Pleated filters are most effective in filtering pollutants and dust particles. They are made of cotton folds or polyester fabrics. In order to get better filtering performance, we recommend you to choose the pleated filters with more pleats.

Washable Air Filters

If you can afford to spend a little more money, then consider getting a washable air filter. Its longer service makes your high upfront cost worthwhile as instead of replacing it; you can clean it whenever you want. It's recommended to read the manufacturer's guidelines to wash and maintain this type of filter. It's also better to go for a regular cleaning cycle a little ahead of time. Moreover, never use a washable air filter when it’s not completely dry to keep it from bacteria buildup and mold growth.

Electrostatic Air Filters

As the name suggests, this type of filter comes with an electrostatic charge that attracts the airborne particles and dust. Its state of the art mechanism keeps the pollutants from spreading across your home. Some of the electrostatic air filters are also washable, which allows you to save a handsome amount of money in the long run.

HEPA Filters

If you’re highly sensitive and prone to allergies and respiratory diseases, then using the HEPA (High-efficiency Particulate Air) filter is best for you. They can filter all types of contaminants with an average efficiency of 99.97 percent. That’s why the Department of Energy of the US recommends it.

UV Filters

It’s yet another air filter that offers a great level of efficiency as it kills viruses and bacteria by using UV (Ultraviolet) light. However, they are not as efficient as HEPA filters to screen pollutants and dust particles. If combating microorganisms is your main concern, then using a UV filter can be a great option.

Final Word

These are some of the best HVAC filter types that you can use for your home’s HVAC system. We hope that this guide will help you to find the right filter according to your unique needs.
