How Can My HVAC Air Filters Affect My Seasonal Allergies?

Particles of pollen, dust mites, and mold spores affect the indoor air quality of every home. These particles can be especially troublesome to those suffering from seasonal allergies. It is important to take steps to reduce the harmful substances in the air and make your home a haven from the allergens outside.

What Can My Air Filter Do for Me?

Air filters have three main components; these make up the “filter triangle.” The first aspect of the filter triangle is capacity. This refers to the number of pleats a filter has. The more pleats, the more surface area for capturing particles in the air. The second component is the air flow allowed through the filter. If your filter has a high capacity but poor airflow, you will run into problems. The third component is efficiency, and this is where the MERV rating system comes into play. When choosing a filter to help with allergies, choose one with a MERV rating between 11 and 13. Higher MERV ratings equal superior efficiency.

I Installed a High-Quality Air Filter, Now What?

Proper maintenance of your HVAC system is key to keeping it running efficiently. A dirty and inefficient HVAC system will not help you with your allergies whatsoever. In fact, it can make them even worse. What can you do to ensure your HVAC continues to run efficiently and keep your indoor air clean? Consider these important maintenance tasks:


  • Change your filter every 1-3 months.
  • n

  • Dust or vacuum your vents.
  • n

  • Keep floor vents cleared of debris.
  • n

  • Clean the coils in your HVAC.

Bring in professionals to maintain and tune up your HVAC system at least once a year.
