Quick Guide to HVAC Filters

HVAC Filters
Posted on in Blogs

Looking for a new HVAC filter can be a daunting task. There are so many different options on the market, each with its own unique number and rating, perhaps making it difficult to choose the right one for your needs.

Check out our quick guide to HVAC filters to gain some insight into the types of HVAC filters available and see which is right for your Beaumont, Texas, home.

What Types of HVAC Filters Are Available?

  • Fiberglass: Most HVAC systems come with fiberglass filters, which remove large dust particles from the air. They are cost-effective and disposable.
  • Pleated: Pleated filters work two ways. They prevent dust and other particles from entering your system, and they remove large particles from the air. They are slightly more effective than fiberglass filters.
  • Electrostatic: These filters are very effective against airborne allergens and dust particles and use static electricity to clean the air in your home.
  • HEPA: High-efficiency particulate-arresting (HEPA) filters capture the smallest particles of dirt and debris, typically used in hospitals and healthcare facilities. To qualify as a HEPA filter, it must be able to remove 99.7 percent of particles from the air.

What If I Want Better Filtration?

If you want better filtration than what you currently have, it's as simple as upgrading to a filter with a better rating. The MERV numbers on your filter will tell you what kinds of particles your current filter removes, so for better air quality, just go for a filter with a higher rating. Generally, filters with a MERV of 7 or 8 are suitable for most homeowners. Just make sure your system is compatible with the type and MERV number of filter you choose.

How Often Should Filters Be Changed?

If you have a pleated or higher efficiency HVAC filter, it should be changed once every three months for maximum efficiency and indoor air quality. During periods of high use or during allergy season, you should inspect your filter and replace it sooner if it looks dirty.
