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. The result is a form factor 40% smaller than its predecessor, yet retains a high Clean Air Delivery Rate (CADR) of up to 310m3/h.
Assembled inside is a Nitec DC motor that changes speed levels seamlessly. Ultra-quiet and unobtrusive, it also consumes very little power
so you can leave it running while you sleep. Smart phone controls allow you to adjust air flow rate, just the way you like it.

About the air pressure system

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, Toray EPA 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 310m3/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
Favourites 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 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 2 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
motors consume just 4.8W, which reduces noise especially on Night
mode. Just like the sound of a gentle breeze, Mi Air Purifier 2 helps you
drift off to sleep.

At 4.8W, power consumption is 58% and less than 0.12kWh①

4.8W   8W   

Takes up less floor space than an A4 paper.
