Features and Benefits

Polluted air first passes through Alen's washable Pre-Filter to capture large particles, extending the life of the filter. In the second layer, air moves through a unique, electrostatically charged HEPA type material that attracts and captures dust, pollen, light smoke, mold spores and other airborne pollutants. In the final layer, clean air passes through a layer of Alen's Activated Carbon, reducing light odors and chemicals commonly found in the air from cleaning products, light smoke, cooking, and various other household materials.
