The AprilAire 813 prevents airborne allergens from circulating through the air in your home by trapping common airborne allergens as they pass through the MERV 13 filter including dust, mold spores, pollen, bacteria, dust mites, and pet dander.

• Up to 93% of airborne viruses that pass through the filtering system are captured.
• Used for basic air cleaning, reduced vacuuming, dusting, allergy sufferers, and allergen removal.
• Better performance thanks to the patented AprilAire Self-Seal Technology which minimizes the amount of air bypassing the filter.
• Your HVAC system is protected from airborne particles, which helps lower energy costs, and can prolong the life of equipment.

MERV means Minimum Efficiency Reporting Value, it is a number assigned to a filter based on its minimum tested efficiency data at a known test condition. The higher the MERV rating the higher the efficiency the filter media is at catching smaller particles in the air.
