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. An electrostatic HVAC filter has fibers that are charged both positively and negatively. This helps the air filter attract airborne particles such as dust and makes your home's air cleaner and safe to breathe in long-term. 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.
