    Merv 8 efficiency rated furnace filters and AC filters can clean your home's air of dust, dust mites debris, lint, pet dander and pollen. 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. The EPA has named Indoor Air Quality (IAQ) as one of the top 5 environmental health risks. Today, people spend almost 90% of their time indoors exposed to air contaminants such as household cleaning products, pet dander, secondhand smoke, mold and more. Change your home air filters regularly to avoid temporary discomfort and the long-term health effects of breathing dirty air.
