Air Filters for Allergies

Many people, even those unaware they're sensitive, suffer from allergies triggered by pet dander circulating in their homes. While up to 30% of allergy sufferers react to cats or dogs, most pet owners aren't using the right filters or replacing them often enough.

The good news is that a quality MERV rated air filter, recommended by ASHRAE for its ability to capture pet dander, mold spores, and dust mites, can bring quick and noticeable relief. Our experience in numerous pet homes confirms that even a simple, cost-effective switch to a MERV rated filter, like the Filterbuy 12x26.5x1 pleated air filter can lead to major improvements in air quality and reduced allergy symptoms.
