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. 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.
