    Merv 13 furnace filters and AC filters can greatly improve indoor air quality by removing household dust, cigarette smoke, microscopic allergens, virus carriers, pollen, pet dander, mold spores, and more. Electrostatic HVAC filters are different than regular home air filters. Negative and positive charges in the filter fibers attract dust and other airborne particles. This helps keep your home's air cleaner and safer for you and your family's long-term health. Indoor air quality has been named as one of the top 5 environmental health risks by the FDA because of pollutants such household cleaning products, mold, smoke and more. Change your home's HVAC filters regularly to ensure your home's air is clean year-round.
