What Are the Different Types of HVAC Filters?

August 14, 2020
One key part of your heating and cooling system is the filter. The truth is, you may not think about it too much. HVAC filters are vital to your system. They keep dirt and debris out of your ducts and equipment. Plus, they boost your indoor air quality. When it comes to filters, there are many types that you can use. Here's what you need to know about the HVAC filter options.

Fiberglass Air Filters

These filters are great at protecting your system. These also help keep the system efficient. But, they're not as good at filtering out pollutants and particles. You will also need to change these filters every 30 days or so.

Benefits:

  • Disposable
  • Easy to find and replace
  • Affordable

Pleated Filters

If you have allergy or respiratory issues, we recommend pleated filters. They often use cotton folds or polyester fabrics. These filters keep dust and other pollutants out of indoor areas.

Benefits:

  • Increased efficiency and cleaner HVAC coils
  • Less dust
  • Fewer HVAC repairs

Washable Air Filters

These filters are a bit more of an investment, but they can pay for themselves over time. Instead of replacing these filters, you clean and reuse them. There's no need to replace them often. When cleaning these filters, follow the directions. Make sure you let your filter dry before reinserting it. This can prevent mold growth in your HVAC system.

Benefits:

  • Good for the environment
  • Often includes a lifetime warranty
  • Available in custom sizes

Electrostatic Air Filters

These filters use a type of filter media that creates static. The electrostatic charge attracts dust and other particles. This is what keeps them out of your system and home. Some of these filters are washable, but some you will need to replace.

Benefits:

  • Good air filtration
  • Improved air quality
  • Cost-effective if you get the washable ones

HEPA Filters

If you have concerns about indoor air quality, we recommend HEPA filters. These are a type of mechanical air filter. HEPA filters block out almost all contaminants (99.97%) by forcing air through a fine mesh.

Benefits:

  • May provide allergy relief
  • Capable of blocking out cigarette smoke and other sources of household odors
  • Improved indoor air quality

UV Filters

Ultraviolet (UV) light kills bacteria and viruses that could get into your home. These filters are not as good at blocking dust and other pollutants. But, these filters still provide protection against many microorganisms.

Benefits:

  • Eliminates allergens
  • Reduces instances of fungal contamination
  • May reduce household sicknesses
