Why Pet Owners Need to Rethink Their Air Filters
Living with pets brings joy—but it also brings dander, hair, and microscopic allergens that standard air filters often miss. If you're using a basic fiberglass filter, chances are it's doing little to capture the airborne particles that aggravate allergies and clog your HVAC system.
The Advantage of 12x20x1 Filters for Pet Households
The 12x20x1 air filter is designed to strike a balance between airflow efficiency and high-level filtration. When paired with a MERV 8 to MERV 13 rating, this filter size can effectively trap pet dander, hair, pollen, and even dust mites—all without overworking your HVAC system. Its compact yet high-capacity design ensures that even smaller systems don’t compromise on indoor air quality.
