Blueair 211+ Auto Air Purifiers White

The Blue Pure 211+ 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 ENERGY STAR® certified air purifier delivers high performance with one-button control and customizable pre-filter colors in a lightweight, compact package. Independently evaluated and third-party tested for performance as part of the AHAM Verifide® Program for room air cleaners, this air purifier has a Clean Air Delivery Rate (CADR) of 353 cfm for fine smoke particles, 380 cfm for pollen particles, and 347 cfm for dust particles. Recommended for large living rooms, family rooms, and playrooms with a 360° air intake to completely filter room air about every 12 minutes¹ (approx. 5x an hour at 550 ft²) on the highest speed.²​ The 3-step combination particle + carbon filter works with Blueair’s filtration technology to remove 99.97% of airborne particles down to 0.1 microns, like pollen, dust, pet dander, mold, bacteria, viruses⁴ and more. An additional layer of activated carbon traps light household odors.⁵​ Blue Pure 211+ Auto quietly cleans the air with less noise than a whisper⁶ on low (23 dB) and up to a normal conversation on high (56 dB) – while using less energy than a light bulb (4-38 W) on all speeds.⁷​ The one-touch enabled Auto mode is designed to help you maintain a comfortable home environment. When enabled, the setting automatically adjusts to real-time conditions reported by the integrated particle sensor. Stay up to date on your air quality with the LED display; it changes color to indicate good, moderate, or poor. Change color in seconds with five fabric pre-filter options inspired by Scandinavian nature. The fabric material of the pre-filter catches larger particles and extends the life of the primary filter. Plus, a hidden compartment in the fabric pre-filter keeps the power cord hidden out of sight. Vacuum the fabric or toss it in the washing machine whenever it needs cleaning. Pre-filter in Arctic Trail (gray) included; Additional colors available for purchase.At Blueair, our Swedish heritage inspires sustainability and quality at the heart of everything we do.
