    AC filters and furnace filters with an efficiency rating of Merv 8 are able to remove pet dander, dust mites debris, lint, dust and pollen from the air. HVAC filters with an electrostatic charge have fibers that contain both negative and positive charges in the filter fibers. The charged fibers attract dust and airborne particles to make your home's air clean and safe for you and your family. 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.
