The DefendAir HEPA 500 combines advanced clean air performance with the ultimate, most functional features to help make the restorer's job easier. * Built-in MICROBAN® antimicrobial product protection to inhibit growth of bacteria, mold, and mildew that can cause stains, odors, and product deterioration * Advanced filtration technology, available through exclusive partnership * Daisy chain capability—link up to 3 units on 1 power outlet * Variable CFM on each unit * Stackable, lightweight, and easily transportable True HEPAThe DefendAir HEPA 500 delivers true High Efficiency Particulate Air (HEPA) filtration of 99.97% against 0.3-micron oily aerosol particles at 500 CFM—the typical airflow level demanded on restoration jobs. The HEPA 500 has been independently tested and verified, so you can feel confident about the filtration efficiency you're really getting—at the airflow you'll use.Maximum CADRThe HEPA 500 offers the assurance of the maximum Clean Air Delivery Rate (CADR), an official standard set by the Association of Home Appliance Manufacturers (AHAM). The HEPA 500 meets the maximum standard set by AHAM (450 CFM). Independent testing (using AHAM protocols) also verifies that the HEPA 500 exceeds AHAM standards by delivering 500 CADR—achieving 99.97% efficiency at 500 CFM.Designed for RestorationWith user-friendly and versatile features, the HEPA 500 is ideal for handling indoor air quality needs on every restoration job. Any job that involves sewage, mold, or fire damage clearly involves significant amounts of particulates and smelly gasses—a direct result of the damage itself.But clean water damage environments are also a concern. The high-velocity airflow needed for drying can stir up particulates that have settled in carpet or on other materials. The HEPA 500 can address indoor air quality quickly and efficiently, and help restore any environment to a pre-loss condition—the ultimate goal of every restoration job.
