The air filter of your HVAC system performs an important function of filtering out dust, pet dander, pollen, and other tiny particles that can enter the space’s air circulation. Breathing air that’s laden with these particles can be detrimental to your health. So, the air filter is one of the most vital components of an HVAC system that maintains the quality of the air that’s circulating within the space.

If you are planning to buy HVAC air filters, then you are likely to come across a variety of them. However, you should always know that air filters with a higher MERV rating show more efficiency compared to their lower-rated counterparts. To buy the best air filter, you should know types of HVAC air filters well. Check them out below:

UV air filters

UV air filters form a part of air cleaners that come with HVAC systems. These air filters use ultraviolet light to kill bacteria, viruses, and other microscopic contaminants that can reduce the quality of air. But the catch is these air filters are not as effective in removing dust. You can still go for them if indoor air quality is a concern for you.

Pleater HVAC air filters

These air filters are either made of polyester or cotton. The cost of these components tends to be skewed towards the higher side, but they are worth a try because of their effectiveness. They are capable of shielding out dust, dirt, and other contaminants from entering your space and being recirculated. These air filters often have a MERV rating somewhere between 5 and 8.

Fiberglass air filters

One of the most affordable HVAC air filters is the fiberglass version. They are disposable and put less pressure on the air conditioner system while sucking in the air. However, they tend to be less effective in barring the entry of contaminants. They aren’t the best option to go for if you suffer from allergies because they have a MERV rating of 4.

HEPA filters

High-efficiency particular air (HEPA) filters are great options to consider if you or anyone at home suffers from respiratory problems and allergies. They can be slightly costlier than the above two options, but rest assured, these HVAC air filters can effectively remove dust, pollen, pet dander, bacteria, and other contaminants.

The above are some HVAC air filters that you can consider for your next replacement and air conditioner service. Make sure you buy products from a trusted source and check the MERV rating of the air filter you are buying to get the maximum value for your money.
