Purifies your room in 10 mins

Xiaomi innovative air pressurization design allows the Mi Air Purifier 2S to provide fast & powerful air purification without taking up too much space. With a Clean Air Delivery Rate (CADR) of 310m/hr, it can effectively clean air in a space of up to 37m






3-layer filtration for maximum purification

360° cylindrical 3-layer filter

The outer layer removes large airborne particles such as dust and hair.
The middle layer uses H11-grade filtration technology from TORAY, Japan. This layer removes micron-sized particles and catches harmful bacteria.
The inner layer, made of high quality activated carbon, effectively removes formaldehyde, other harmful substances and odour.






Efficient tower-structure design

The classic tower-structure design, proven effective by two generations of air purifiers, ensures maximum efficiency while keeping a compact design. 943 intake holes help in increasing the air intake space and forming a 360° cyclical air filtration pathway.








Smart control with Mi Home App

Control the xiaomi mi air purifier 2s from anywhere using Mi Home App. Check the air quality, temperature and humidity, adjust the fan strength and set a timer to power on the purifier. The App also automatically notifies you when it’s time to replace the filter.








Silent and energy efficient

The Mi Air Purifier 2S is meticulously designed to reduce noise. In sleep mode, the sound produced is almost imperceptible. Equipped with Nidec motor from Japan, the purifier consumes only 4.8W power in normal mode, which is less than that of a fluorescent light bulb.
