How are Alen® filters capturing contaminants?

Alen® filters use a dense network of randomly arranged fibers to trap tiny, harmful particles. This process is standard for filters using HEPA material, capturing particles like household dust, hair, pet dander, pollen, mold spores, bacteria, and much more. We also have filters that trap odors within a honeycomb layer, containing a blend of specially treated, proprietary granular carbon and odor catalyst beads.

What are the differences in Alen® filters?

All of our filters are made from medical-grade HEPA material, but some of our filter contain additional material to capture particulates beyond what HEPA captures.Pure: strictly HEPA material.Fresh: contains added carbon layer.VOC/Smoke: contains added carbon layer.Odor: added honeycomb layer that contains a blend of specially treated, proprietary granular carbon and odor catalyst beads.

How long do Alen® filters last?

Although a filter's lifespan depends on the level of usage and each environment, here is a general breakdown: Pure filters are the longest lasting and are rated and tested for 9-15 months. Fresh, Odor, and VOC/Smoke filters all containing carbon have a slightly shorter lifespan of 6-10 months. Dust Pollen Hair Bacteria Mold Smoke VOCs Smog
