    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. Pet dander, mold, secondhand smoke, household cleaning products and more all contribute to dirty air inside your home. The fact that people spend 90% of their time indoors, and that the air inside is often more dirty than the air outside, led the EPA to name Indoor Air Quality (IAQ) as a top five environmental health risk. Change your home air filters regularly to prevent temporary and long-term negative health effects from breathing in dirty air.
