The fabric pre-filter extends the life of the primary filter, catching large airborne particles such as dust, lint, pollen, and pet hair. And the color can be customized to fit your space.

The built-in LED warning system glows red when it's time for a change. For optimal performance, we recommend replacing every 6 months.
