Our fabric pre-filters extend the life of primary filters, catching large airborne particles such as dust, lint, pollen, and pet hair. They're colorful too, and can be customized to compliment your space.
seconds
Up to five available colors let you add a splash of color or a shade to compliment your space. Choose from Arctic Trail, Winter Reed, Archipelago Sand, Aurora Light, and Night Waves.
While this pre-filter is designed to be compatible with the 411 Auto, it may also be used with Blue Pure 411 and MINI models at a slightly increased noise level. Pre-filter is not compatible with the 411+ model.
For quick cleaning, use the brush attachment on your vacuum to clean the exterior of the fabric pre-filter of visible dust and dirt between washes.
Designed to be reused when the pre-filter requires a deeper clean, washed on a gentle, low-temperature cycle in the washing machine. Hang to dry.
A hidden velcro-panel in the fabric pre-filter holds the power cord, keeping it close to the body of the air purifier and out of sight.
We designed our new premium fabric pre-filters in an earthy color palette inspired by our Swedish heritage and Scandinavia's natural landscapes.
