    Product Description

    Blueair Pre-filter in Arctic Trail color for the Blue Pure 411 Auto air purifier. The pre-filter may also be used with Blue Pure 411 and MINI models at a slightly increased noise level (2 dB). Pre-filter is not compatible with the 411+ model. Form meets function in Blue Pure 411 Auto's colorful pre-filters. The fabric allows you to customize the color to match your style, as well as extend the life of the primary filter, catching large airborne particles such as dust, lint, pollen, and pet hair. Vacuum the exterior of the fabric pre-filter to remove visible dust and dirt as often as you'd like. Removable, washable, and reusable the pre-filter is designed to be used again and again. When it requires a deeper clean, throw the fabric in the washing machine on a gentle, low-temperature cycle. Hang to dry. A hidden compartment in the fabric pre-filter keeps the power cord hidden out of sight. Available in five pre-filter colors inspired by natural Scandinavian landscapes; Arctic Trail (gray), Winter Reed (light gray), Archipelago Sand (pink), Aurora Light (green), and Night Waves (navy). Pre-filter in Arctic Trail color comes standard with air purifier.
