HEPA filters create cleaner air
for a healthy life

Continuing our legacy of self-developing more effective air pressurization systems, we equipped the Mi Air Purifier 2H with HEPA filters, which are so effective that at least 99.97% of particulate matter of size 0.3μm or larger is filtered on the first pass-through. The air becomes so clean that it can help alleviate allergies and asthma symptoms, helping to make beautiful spring days a bit brighter.

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 home(1). 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

Mi Air Purifier 2

Purifies room air in 10 minutes High performance 310m3/h CADR


CADR (Clean Air Delivery Rate) is the international standard for measuring air purifier effectiveness. Mi Air Purifier 2's CADR is measured under specified test
and capacity conditions with targeted pollutants (particulate and gaseous) with measurement units in cubic meters per hour (m3/h).

  1. Results according to Guangzhou Industrial Microbiology Testing Centre's CADR test report. Takes 10min to circulate clean air in a 21m2 room, 2.4m high.
  2. CADR is affected by room area and height. Mi Air Purifier 2's effective area is based on the GB/T 18801 Air Purifier standard: Effective area=CADR x (0.07-0.12). Data taken from Guangzhou Industrial Microbiology Testing Centre's CADR test report.
  3. Install the Mi Home app to control Mi Air Purifier 2 remotely. Noise levels on High-speed mode will be higher than Normal or Night mode.
  4. Toray EPA filter removes extremely fine particles and contaminants including airborne allergens (pollen, dust mites, pet dander, mold, etc.) as well as bacteria and some viruses.
  5. Results according to Guangzhou Industrial Microbiology Testing Centre's CADR test report.
  6. Mi Air Purifier 2 uses 58% less energy than Mi Air Purifier when both devices are on High-speed mode. 4.8W power consumption takes place when in Normal mode.
    Appearance details may vary slightly with different production batches, and may be subject to change without prior notice.

PET Primary filter

360° cylindrical filtration

Made with PET (polyethylene terephthalate), the outer layer is 3 to 5 times tougher than comparable models. It has high flexural strength and is resistant to folding, grease, fats, acids, alkalis and most solvents. The cylindrical shape provides 360° filtration of dust, hair and other larger floating particles.

Filter replacement is a breeze

Change filters in 10 seconds

Typical air purifiers require you to change filters layer by layer. Mi Air Purifier 2H simplifies this by integrating all three layers. Simply pull out, and push in. It's that easy.

Alerts you to change filters Monitor filter usage in real time

All filters lose effectiveness over time and must be replaced promptly. Filters not replaced on time may not block harmful substances or may cause secondary contamination. Contrary to what others may advertise, cleaning old filters with water or a vacuum cleaner does not guarantee that the filter will regain its effectiveness.

We recommend you change filters every six months or less, depending on usage. Use the Mi Home app to monitor filter lifespan and receive notification reminders when your filter needs replacing.

The beauty of aerodynamics

Air flow optimization at its best

Inspired by aircraft engines, our engineers set to create a powerful aerodynamic system that uses pressure to let clean air soar across the room. Assembled inside is a Nidec DC motor that changes speed levels seamlessly. It manages to clean 260m³/h while staying ultra-quiet and consuming very little power. As soon as you power it on, a steady flow of air begins to fill the whole room. Smart phone controls allow you to adjust air flow rate just the way you like it.


Axial fan

Increases wind speed, propels air evenly upwards for a powerful 360° room circulation.


Brushless DC motor

The custom brushless DC motor is the ideal engine for seamless speed transitions. Supplied by world-renown Japanese manufacturer, Nidec, the high-quality motor also lasts twice as long as typical brushless DC motors.


Mixed flow blades

The 9-blade design uses a mixture of axial and turbine blades to generate high-pressured gusts of wind. It draws unclean air through the base and propels air through the top of the air purifier.


Tapered air ducts

The smaller, tapered air ducts allow for a compact design. Created with high-quality plastic from Samsung and Toray, the air ducts are extremely smooth to create better air flow.


Triple-layer filtration

The custom cylindrical filter has a full 360° air intake. The triple-layer filter uses a primary filter, HEPA filter and activated carbon filter to remove airborne particles while letting clean air pass through.


Clean air comes full circle

Large 360° circulation, up to 260m3/h CADR

Uses aerodynamics to optimize wind flow. Air suction takes place at the base and is expelled forcefully through the top using a pressurized system. Select Favorites via the Mi Home app to enter high speed mode, and purify your room in a matter of minutes.


Going with the flow

Even a fan blade just 1mm thick can have a significant impact on airflow, that’s why Mi Air Purifier 2H has been meticulously designed to minimize air resistance and energy loss as air flows through each section.


Intake Grille

Faces the same airflow direction and slices it
up for even circulation. Rounded sections
reduce wind resistance and noise.


Fast and steady

The best fans remain stable and precise even at full speed. Every fan is tested for precision and balance at high rotation speeds for the most stable performance.


Parallel fan design

Both fans at the top and bottom work together in sync to provide a uniform air passage.


Senses with accuracy

The high-quality Japanese SHINYEI particle sensor calculates indoor PM2.5 quality and displays it on your phone. It also informs Mi Air Purifier 2 to adjust wind speeds when air gets bad.

So dim and quiet, you won't even realise it's there

Mi Air Purifier 2H is designed simply, with minimal aesthetics, buttons, and lights. The notification light hovers exactly 7.5cm from the ground to avoid glare when you're resting on the bed or couch. The low-power Nidec motor consumes just 4.8W, which reduces noise - especially on Night mode. Just like the sound of a gentle breeze, Mi Air Purifier 2H helps you drift off to sleep.

At 4.8W, power consumption is 58% and less than 0.12kWh

4.8 W

Takes up less floor space than an A4 paper.
