Merv 13 efficiency rated furnace filters and AC filters can clean your home's air of pet dander, microscopic allergens, virus carriers, pollen, household dust, cigarette smoke, mold spores and more. Electrostatically charged HVAC filters contain both negative and positive charges in the fibers and are designed to attract airborne particles such as dust to keep your home's air clean. Indoor air quality can be even more polluted than outdoor air from mold, household cleaning products, pet dander and more. Given people spend almost 90% of the time indoors, make sure to change your home air filters regularly to avoid the long-term negative health effects of breathing in dirty air.
