Blueair Blue Pure 311 AUTO

The Blue Pure 311 Auto air purifier takes a simple approach to air quality management with an integrated particle sensor, Auto mode setting, and LED air quality display. The air purifier delivers high performance with one-button control and customizable pre-filter colors in a lightweight, compact package. Independently evaluated for performance by the AHAM Verifide® Program for room air cleaners for a Clean Air Delivery Rate (CADR) of 250 for fine smoke particles, 250 for pollen particles, and 244 for dust particles. Recommended for medium rooms like a master bedroom, living room, or playroom with a 360° air intake to completely filter room air about every 12 minutes (about 5x an hour at 388 ft²) on high. The 3-step filter works with Blueair’s HEPASilent™ filtration technology to remove 99.97% of airborne particles down to 0.1 microns, like pollen, dust, pet dander, mold, bacteria, viruses⁰ and more, while a layer of activated coconut carbon traps light household odors. The one-touch enabled Auto mode setting automatically adjusts to real-time conditions reported by the integrated particle sensor while the LED air quality display updates with one of three colors indicate air quality. Cleans the air with noise levels equivalent to a whisper on low (23-53 dB), and ENERGY STAR certified energy efficiency (3-35 W). Change color in seconds with five fabric pre-filters inspired by Scandinavian nature. The pre-filter catches larger particles and extends the life of the primary filter.
