Breathe Healthy

New OLED screen displays the quality of air you breathe

The newly added OLED display allows you to check PM2.5 levels in the room and
keeps track of how clean your air is. It also shows the temperature and humidity levels.

AQI display Favourite modeSleep modeAuto mode

Automatic brightness adjustment

The Mi Air Purifier 2S display automatically adjusts its brightness according to ambient light,
so that your sleep is not disturbed

High-precision laser sensor

The highly accurate Particulate Matter (PM) sensor detects
particles as small as 0.3 μm[1] and instantly displays the AQI
on the OLED screen

Purifies your room in 10 mins* with a CADR of 310m³/hr

Our 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)[2] of 310m³/hr, it can effectively clean air in a space of up to 37m²[3]

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[4] 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[5]

Control the 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[6].
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.

[1]CADR (Clean Air Delivery Rate) is the international standard for measuring air purifier's effectiveness. Mi Air Purifier 2's CADR is measured under specified test and capacity conditions with targeted pollutants (particulate and gaseous) having measurement units in cubic meters per hour (m³/h).
[2]CADR value is calculated according to the inspection report provided by China Home Appliance Inspection, inspection report number: WCk-17-50468WCk-17-50468
[3]CADR is affected by room area and height. The Mi Air Purifier 2S effectiveness area is calculated as CADR x (0.07-0.12). Relevant CADR data is obtained from the inspection report by China Home Appliance Inspection.
[4]The filtration technology provided by Toray is able to remove minute particles from the air, including common allergens (pollen, dust mites, pet dander, mold, etc.) as well as bacteria and some viruses.

[6]Using the Mi Home app, the mode can be chosen according to your needs. When using higher modes, noise produced by the device may increase. Noise testing was provided by Shanghai Environmental Protection Product Monitoring and Inspection, report number: 2017120-35-1208815001.
[7]*Results according to Guangzhou Industrial Microbiology Testing Centre's CADR test report. Mi Air Purifier 2S takes 10 min to circulate clean air in a 21m2 room, 2.4m high.
