Mi Air Purifier 2

The smart way to breathe
  • Real-time AQI monitoring
  • Mi Home app, smart remote controls
  • 400 sq. ft. coverage, 360° triple-layer filter

Clean each breath of air

Purifies room in 10 minutes
  • We know eating clean is better for the body, and the same applies to the air we breathe. Mi Air Purifier 2 is simple, elegant and has a new compact design that is 40% smaller than the first Mi Air Purifier. Despite this, it still offers a high 310m3/h Clean Air Delivery Rate (CADR) ② and takes just 10 minutes to circulate purified air in a 21m2 room. Go on, isn't it about time you give your lungs a treat?

Every way the wind blows

High air pressure, larger circulation
  • Send powerful gusts of air to the farthest reaches of your room. Inspired by aircraft engines, the aerodynamic pressure system created by our R&D team draws inward from the base and expels air upwards with great force. Smart phone controls let you switch on and off remotely, even when you are away from home③. That way you can always be sure to come home to clean air.

Covers all angles

360°triple-layer filter
  • The 360° cylindrical filter takes in air more efficiently from every direction compared to conventional air purifiers. Its triple-layer design removes particles larger than 0.3μm with a high-density EPA filter from Japanese manufacturer Toray, while an activated coconut carbon filter removes formaldehyde, bad odour and other harmful substances.④ Replacing the filter is simple and you will be automatically notified via the app when it needs replacing

Completely in control

Monitor air quality at a glance

Use your phone as a remote to power on, power off, and switch modes. The Mi Home app also lets you monitor home air quality from your phone at any time. Create schedules to power on, power off, switch to Night mode, and more.

The strong, silent type

Ultra-quiet and energy efficient

Sleep soundly with the ultra-quiet Mi Air Purifier 2. Advanced aerodynamics reduce noise and wind resistance so you can enjoy peace and silence at night. The custom Japanese motor from Nidec is extremely power efficient, consuming 58% less energy than Mi Air Purifier and using only 4.8W on normal mode - that's even better than energy-saving lightbulbs.⑥

310m 3/h
(Clean air delivery rate)
CADR (Clean Air Delivery Rate) is the international standard for measuring air purifier effectiveness. Rigorous tests are performed using dust, second-hand smoke and pollen to calculate the rate of clean air delivery per unit of time. The higher the CADR, the more effective the purifier.
21m 2~ 37m 2
Recommended effective area
Effective area is based on the CADR and may be affected by factors such as room height and plot ratio. Mi Air Purifier's effective area is based on the GB/T 18801 Air Purifier standard: Effective area = CADR x (0.07-0.12)
