HEPA type replacement filter with Pre-Filter for dust and allergen removal and a thick layer of Activated Carbon for chemical and odor control.
Designed for the Alen BreatheSmart HEPA Air Purifier, the Alen HEPA-FreshPlus Filter combines three layers of filter technology to purify and freshen the air in your home. 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, smoke, mold spores and other airborne pollutants. In the final layer, clean air passes through a thick layer of Alen's Activated Carbon (3 lbs), reducing odors and chemicals commonly found in the air from cleaning products, smoke, cooking, and various other household materials.
There is no warranty for Alen filters.
