HVAC Filters Explained

This entry was posted in HVAC Systems, Uncategorized on by .

With hay fever season approaching rapidly, it’s a great time to showcase one of the most integral components of your HVAC system—the air filter. HVAC filters help keep your home clean and healthy. But there is more than one option when it comes to choosing a filter. Here are the types of air filters to choose from and a few details to help you make the right choice for your household.

Fiberglass

These are the most common and most affordable option. Fiberglass air filters are effective in helping to keep your system efficient, but they’re not the best choice for removing dust and pollutants from your indoor air. If you’re prone to allergies or other respiratory problems, you may want to consider a higher-grade filter.

Pleated

Fabricated from polyester or cotton folds, pleated air filters are more effective at filtering particulates than those made from fiberglass. Filtering performance of pleated filters is determined by the number of pleats. The more pleats, the greater the performance. Both fiberglass and pleated filters should be swapped out at least once a quarter. Here in the desert, it’s a good idea to get on a regular monthly schedule of changing your air filter.

Washable

Although more expensive than disposable fiberglass or pleated filters, washable filters can save you in the long run. They can be easily cleaned, so you don’t need to replace them. It’s important to clean them according to the recommended schedule determined by the manufacturer. You’ll want to ensure the filter is completely dry before using it to prevent mold and bacteria growth.

Electrostatic

Electrostatic air filters attract dust and airborne particulates through electrostatic charge, preventing them from being blown through your home. These filters come in both washable and one-use models.

HEPA

High efficiency particulate air (HEPA) filters are a good choice for homeowners with allergies and respiratory conditions. They have been proven to be effective in screening up to 99.97% of contaminants. The US Department of Energy recommends this type of filter in homes and businesses.

UV

Using ultraviolet light to kill bacteria and viruses, UV filters have become more popular since the start of COVID-19. However, it’s important to note that these filters are better at killing microorganisms than screening dust and other pollutants. This is why some recommend using a UV filter in conjunction with a standard air filter.
