The U.S. Department of Energy recommends that consumers clean or replace window air conditioner filters often to conserve energy and save money. Many HVAC specialists suggest that you swap or clean re-usable filters every four to six weeks to keep your AC in top condition. Frost King recommends that you change or wash your air conditioner filter at least every sixty days. If you already have a Frost King re-usable window air conditioner filter, you rarely need to change it. Simply remove it, clean it with warm water, let it dry and re-attach it to your AC unit. Replacing or cleaning re-usable air conditioner filters is essential for effective and efficient indoor air cooling throughout the summer. Not only does it improve AC performance—which helps lower skyrocketing energy bill costs—it improves indoor air quality. Did you know that indoor air pollution is one of the top environmental health risks for children and adults? By changing or washing re-usable air conditioner filters every four to eight weeks, you're removing dust and pollutants from the air to protect your family from airborne allergens and illnesses. Since all Frost King air conditioner filters are washable and re-usable, you don't have to worry about the cost of replacement every few weeks. Cleaning your re-usable air conditioner filter with pan of warm water and a little dish soap is easy. Simply follow the included instructions. Frost King air conditioner filters are available in polyurethane foam, fiberglass, electrostatic and carbon. They can be trimmed to any size that fits almost any air return.
