Designed for the Alen A350 and A375 Air Purifiers, the Alen Odor-Tech Filter combines three layers of filter technology to purify the air in your home while destroying heavy odors at a molecular level. 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 layer of Alen’s Activated Carbon to reduce odors and chemicals commonly found in the air from cleaning products, smoke, cooking, pets and other household items. In the final layer, clean air passes through hundreds of cells filled with Alen’s patented Molecular Conversion Powder where tough odors like tobacco smoke are destroyed at a molecular level, leaving the air smelling fresh and pure.

• Over time, the Odor-Tech Filter becomes overloaded with particles and pollutants, decreasing its filtration performance. We recommend regular filter replacements, at least every 6 months with normal use.
• Rinse or lightly vacuum the removable black Alen Pre-Filter as soon as it develops a layer of visible particles. Allow it to completely dry before replacing.
