What is a Prefilter and how does it work?

The prefilter is the fabric layer that covers the exterior of your filter to capture larger particles such as dust and hair. Think of it as the first line of defense against airborne contaminants.

  • On the BreatheSmart 75i, the prefilter is a white screen material.
  • All other Alen BreatheSmart purifiers use a black felt-like material. These prefilters attach to your filter using Velcro-like strips for easy removal and replacement. We recommend cleaning by vacuuming, but not washing.

Alen prefilters are now stronger, longer-lasting, and easier to clean. Committed to innovation and improvement, we believe durability goes hand-in-hand with purifying performance.
