Alen (TF30) HEPA-Fresh Replacement Filter for T100 and T300 Air Purifiers, 1-Pack (set of 2 filters);

Comes standard with the Allen T100 and T300 air purifiers, the Allen heap-fresh filter combines three layers of filter technology to Purify and freshen the air in your home. Polluted air first passes through Allen 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 style material that attracts and captures dust, pollen, pet dander, mold spores and other airborne pollutants. In the final layer, clean air passes through a layer of Allen activated carbon, reducing light odors and chemicals commonly found in the air from cleaning products, smoke, cooking, pets and various other household materials. Note: the heap-fresh (TF30) replacement filter includes two (2) filters. The Allen T300 air purifier requires both filters. The Allen T100 air purifier requires only one. Instructions for use: over time, the heap-fresh filter becomes Overloaded with particles, decreasing its filtration performance. We recommend Regular filter replacements, at least every 6 months with normal use. Rinse or lightly vacuum the removable black Allen Pre-Filter as soon as it develops a layer of visible particles. Allow it to completely dry before replacing. Washing or vacuuming the white HEPA style material will damage the fibers and is not recommended.
