BLUEAIR Blue Pure 311 Auto Gray Pre-Filter, Washable Fabric Traps Pollen, Pet Dander & Dust, Arctic TrailOnline

COMPATIBLE WITH BLUE PURE 311 AUTO: Genuine Blueair Replacement Pre-filter in Arctic Trail (gray) color for Blue Pure 311 Auto air purifiers

FILTER LIFE EXTENSION: Colorful fabric pre-filter extends the life of the primary filter, catching large particles such as dust, lint, pollen and pet hair

NO COMPARISON: Genuine Blueair pre-filters are specifically designed to enable optimal air flow and performance over time; When combined with electrostatic filtration, this results in faster and quieter cleaning than traditional HEPA filtration

CLEAN WITH EASE: Vacuum the exterior of the fabric pre-filter to remove visible dust and dirt as often as you’d like and as-needed based on indoor air conditions

DESIGNED FOR REUSE: When the pre-filter requires a deeper clean, wash on a gentle, low-temperature cycle in the washing machine

DISGUISES CORDS: A hidden compartment in the fabric pre-filter keeps the air purifier’s power cord hidden out of sight

CUSTOMIZE WITH SWEDISH-INSPIRED COLORS: 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)
