How To Choose the Best AC Filter for Allergy Season?

Discover 3 HVAC Filter Options That Help Keep Allergies Away

Spring has sprung, and with it comes beautiful flowers, rain showers, and, unfortunately, allergy season. If runny noses, itchy eyes, and sore throats are common in the house, it may be time to consider a new type of HVAC filter. 

Sure, most furnaces and air conditioners come with a filter, but not all filters are made alike, and some do a better job fending off allergens indoors. Choosing the right filter can make allergy season easier on the entire household. Keep reading to find out the different types of air filters and how they can help keep allergens out of the home!

Option 1: Fiberglass Filtersfilter

Before exploring HVAC filters, it's essential to understand what MERV means. MERV stands for the "minimum efficiency reporting value" of a filter and indicates how well the filter removes airborne particles from the air. 

When it comes to fiberglass filters, the MERV Rating isn't great. The average MERV rating of fiberglass filters is between 1-4 on a scale of 1-16, with 16 being the best at filtering out pollutants and allergens.

Though fiberglass filters are cheap, they are incredibly inefficient and require more frequent replacement than other filter types. Fiberglass filters may allow for better airflow when filters are new and clean. Still, unfortunately, they also allow more allergens and pollutants to slip through the large filtration screen into the ductwork for occupants to breathe in.

Option 2: Washable/Reusable Filters

Washable filters are an eco-friendly solution for air filtration. Washable filters work by using electrostatics that charge air particles through friction, leaving the pollutants stuck to the filter. However, washable filters tend to have a lower MERV rating around 1-4 as well. These filters are reusable and require regular washing to operate efficiently. 

Washable, reusable filters cost more than fiberglass options initially, but a home typically only needs one or two for the entire life of an HVAC system, meaning they are cheaper in the long run. Maintenance for reusable filters typically means a run through the washer and drying entirely before being reused. 

Option 3: HEPA Filtershepa

HEPA filters are the gold standard of air filtration for any household. HEPA filters, or High-Efficiency Particulate Air Filters, are so good at cleaning the air they're recommended by the U.S. Department of Health because of their efficiency. HEPA filters remove at least 99.97% of airborne pollutants and allergens from the air. Their MERV score sits at an impressive 16, meaning they are the best filter for protecting an allergy-prone household from the hazards of allergy season. 

Bear in mind the HEPA filters are great for removing allergens, dust, and mold spores, but they aren't great for fumes, gases, and odors. Additionally, they require regular replacement throughout the year to maintain their efficiency and become less efficient if clogged or dirty. But in terms of allergy protection, HEPA filters are some of the best filters around. 

When choosing the right air filter, it's essential to keep in mind the filter's efficiency and cost. Whenever questions regarding the right filter come up, homeowners should reach out to a local HVAC expert on the right product to suit their situation.
