Blue Pure 411 Auto Pre-Filter
Where form meets function
Our fabric pre-filters extend the life of primary filters, catching large airborne particles such as dust, lint, pollen, and pet hair.
A hidden compartment in the fabric keeps the power cord hidden out of sight, and they're colorful — with different options to complement your space.
Switch color in seconds
Up to 5 Scandinavian-inspired colors let you add a splash of color or a shade to compliment your space. Night Waves and Arctic Trail Pre-Filters come as standard with your Blue Pure Auto air purifier.
Designed for compatibility with the 411 Auto. Can also be used with Blue Pure 411 and MINI models at a slightly increased noise level. 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.
When the pre-filter requires a deeper clean, wash on a gentle, low-temperature cycle in a washing machine. Hang to dry.
