About this item

• Purifies Large Rooms with Ease - With 520 m3/h CADR, the AC3221 covers rooms up to 1453 sqft (135 m2 NRCC) or 670 sqft (62 m2 GB/T), built for bigger living spaces.
• 3-Layer HEPA NanoProtect Filtration - Captures 99.97% of particles down to 0.003 microns, 100x smaller than standard HEPA filters. Uses an electrostatic charge to attract pollutants, cleaning up to 2X more air than traditional HEPA H13 filtration.
• Quiet Even at Maximum Power with SilentWings - Stay quiet even on Turbo power, so purification never disrupts your day.
• AeraSense Smart Sensing with Color AQI Indicator - Tracks PM2.5, Temperature, and Humidity in real time, with a color-changing light ring that glows blue for clean air and red as pollution rises, plus an exact PM2.5 number on display.
• Dual Fan, 30% More Purifying Power - Two fans work together to purify 30% faster than a single-fan purifier of the same size, so bigger rooms get clean, fresh air sooner.
