    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. Negative health effects from indoor air pollutants such as mold, secondhand smoke and household cleaning products can be experienced soon after exposure or even years later. Because people spend up to 90% of their time indoors, the EPA has named Indoor Air Quality (IAQ) a top five environmental health risk. Change your home air filters at least every 3 months to keep the air in your home safe to breathe.
