Did you know? The space we live in is polluted with filthy air, which may contain harmful gases, dust particles, smoke, smog, and other elements that contaminate it. Our respiratory organs are not made for tackling these kinds of circumstances where the air becomes unbreathable. According to the Centers for Disease Control and Prevention, 1 out of every 12 people have asthma, which is an alarming number, and we should try to control it. Additionally, contaminated air also damages your lungs and heart causing them to go through possible organ failure.

Considering the facts now, we know that clean air is as essential as a healthy meal; air purifiers are the only solution left for making your space neat and pollutants-free. They are used to clean the air around us by removing pollutants, allergens, and bacteria. Today we present to you a futuristic and highly efficient air purifier for you; the Xiaomi air purifier is a high-performance air purifier with a comparatively high CADR of up to 406 m³/h.

Key features of Xiaomi air purifier

Below are the few key features of the Xiaomi air purifier mentioned; we will discuss them in detail to allow you to make an informed decision before buying this air purifier.

  • High CADR
  • 360° cylindrical design
  • 3 step filtration process
  • Smart remote control
  • Different operating modes
  • Air quality indicators
  • Child safety lock


CADR is a standard for measuring the efficiency of an air filter. Clean air delivery rate is defined as the amount of clean air delivered to a room in cubic feet per minute divided by the amount of clean air required to dilute or remove all particles from a room. Xiaomi Air purifier is capable of cleaning Cleans 406m³ of air per minute which makes it stand out of all cleaners from this league.

It takes up to 12 minutes to purify the air in a room-sized between 28.4m²~48.7m². The Effective area is based on the CADR and may be affected by factors such as room height and plot ratio. Xiaomi Air Purifier’s effective area is based on the GB/T 18801 Air Purifier standard: Effective area=CADR x (0.07-0.12).

360° cylindrical design

Xiaomi Air purifier comes with a 360° cylindrical design like other top air purifier manufacturers use in the US. This cylindrical design allows the air to enter the air purifier from all dimensions resulting in increasing the air intake of the purifier as well as the overall speed of the cleaning process. The outer body of this air purifier has 5732 tiny holes for air to enter it from all angles.

Most air purifiers use only one fan for intake and output, which reduces the flow speed of the air that passes through the filters and air ducts. Instead, Xiaomi Air Purifier uses an independent blower to boost airspeed and has a 9-blade fan for even and consistent output. These 9-blade fans are powered by a Smart brushless DC motor made by Nidec’s Japanese manufacturer. The built-in driver circuit of the brushless DC motor delivers seamless speed control and has twice the lifespan of comparable models.

3 step filtration process

Xiaomi air purifier is equipped with 3 steps to filter the air to ensure its quality is up to the mark. The filtration processes are mentioned below; let’s get into the details one by one.

  1. Primary filter
  2. HEPA filter
  3. Coconut activated carbon filter

Primary filter

It is the first layer of filtration; the outer layer of this product is made from PET, which is more resilient to various types of fluids and is designed to resist folding, grease, acids, and alkalis. Its cylindrical shape provides 360 filtrations of dust and other floating particles.

HEPA filter

The second step of filtration includes an Ultra-dense H11-grade HEPA filter which filters up to 99.3% of PM0.3 and is often used in hospitals and laboratories for high-efficiency removal of small particles such as dust and pollen. The Xiaomi Air Purifier uses a combination of a Toray PP and PET filter to effectively remove 99% of airborne particles, such as PM2.5 and PM0.3 from the air.

Coconut activated carbon filter.

It is the third and last step of filtration; quality coconut for the preparation of this filter is sourced from South Asia. This filter eliminates the harmful gases from the air that the HEPA filter is unable to filter. Xiaomi Air Purifier’s coconut activated carbon is among the most effective of its kind. It is combined with an anti-formaldehyde formula that effectively absorbs harmful chemicals such as formaldehyde, benzene, ammonia, and odours and smoke.

Smart remote control

Mi smart air purifier application is available on both the Google play store and Apple store. You can control and monitor the functions of your air purifier with a tap of your finger.

  • Different modes available
  • You can monitor the air quality.
  • Reminds you to change the filter
  • You can turn ON/OFF the air purifier.

Different operating modes

It offers three operating modes, discussed below.

High-speed mode

The high-speed mode maximizes the air purifier’s performance; by enabling this mode, the fan speed increases, which may cause higher power consumption. It can filter out all the air within the room-sized 48.7m² in just 12 minutes at the rate of 10000 litres per minute.

Night mode

When you turn on the night mode, the speed of the fan will decrease, which ultimately minimizes the noise production. Night mode lets the Mi Air Purifier run quietly in the background, allowing you to enjoy clean air while you sleep.

Auto mode

There is a built-in air quality detection sensor present Xiaomi air purifier; it detects current air quality and optimizes the settings accordingly. It reduces your electricity cost and enhances the performance of an air purifier.

Child safety lock

They do not mention any child safety lock function in their product specification. However, the air purifier shuts down its fan in case of accidental removal of the top grill, making it safer for children.

Other salient functions

  • Light sensor: turn on night mode when detecting low light.
  • Wi-Fi indicator light: indicates the connection with Wi-Fi.
  • Air quality indicator light: ensures the working of the air quality indicator.


Xiaomi air purifier has a lot to offer in terms of features and specifications; in our opinion, you should definitely go for it because it has three filtration steps which ensure to give you maximum pure air. Additionally, it has a good design and speedy cleansing capabilities.
