Three years ago the first World Internet Conference was held in. in the frame of this conference Lei Jun, Xiaomi CEO and Jack Ma, Founder and Executive Chairman of Alibaba Group attended a meeting. At the scene of the summit, Lei Jun talked about the vision of developing mobile phones in the next ten years. However, Ma said: ‘the air and water are polluted. What’s the use of mobile phones?’ This had a great impact on Lei Jun, and a month later Xiaomi released the first-gen Mi Purifier.
The Xiaomi Mi Air Purifier was considered as an entry-level product. But this feature mainly refers to the pricing and not to the specs. Later the company came in with the Pro variant. Last year the company launched the Xiaomi Mi Air Purifier 2 that performed quite well.
In 2017, this market has enlarged and became attractive to more manufacturers. Each of them wants to get its own piece of the pie. But with the launch of the Xiaomi Mi Air Purifier 2S this manufacturer clearly showed it will continue aiming at entry-level models with a low pricing not leaving a chance to others. It’s priced at only 899 yuan ($136) that means we are dealing with one of the cheapest air purifiers in the world. Of course, this is a Xiaomi product, which simply means this purifier sports a stylish and minimalistic design, good hardware, some ‘smart’ features, and an overall great performance. But this niche is growing rapidly, and the manufacturer should look forward not to skip forward companies such as Ecovacs that has already announced the world’s first walking air purifier dubbed as the Atmobot AA3.
Xiaomi Mi Air Purifier 2S Appearance
This model looks almost identical to the previous air purifiers, though the company has canceled the indicator in the upper right corner. However, there is still an OLED display for all important info to be viewed.
The small screen on the front displays real-time PM2.5 concentration, temperature, humidity, Wi-Fi connection, and working mode.
The back clip opens easily and with no efforts.
Staring the second generation the Xiaomi Mi Air Purifier comes with a comfortable design allowing to get off the filter and replace it manually. There is also a small ring to ensure the air tightness after the replacement.
Actually, there are a few variants of the filter such as enhanced version and antibacterial version. The Purifier comes with the standard version by default.
The standard version filter uses a three-tier structure. The outermost surface of the filter is for large particles such as hair and dust. The middle one is the most important filter dubbed as HEPA (High-efficiency particulate air), which mainly removes small particles such as PM2.5. And finally, the third one is an activated carbon to remove formaldehyde and other harmful substances such as odor.
The Xiaomi Mi Air Purifier 2S still continues using the tower air duct structure, which forms a three-dimensional cycle of purified air, while the circular filter can make good use of the entire filter to achieve a better filtering effect.
Such an appearance allows the purifier to purify the air to the level of human breath quickly. However, if you place this air purifier too close to the wall, it will obviously affect the efficiency of air purification.
The overall design and dimensions are quite acceptable. Its height is only 52cm, while the width is 24cm. there is also a power cord with a length of 1.6 meters.
Xiaomi Mi Air Purifier 2S Control
Once the Xiaomi Mi Air Purifier 2S is connected to the power, you can push the only button on it and use it. There are no other keys to control. So everything is implemented via that single key to start, shut down, and switch between modes. However, if you want to use all of its functions, you have to use the APP.
Once you open the Mi Home app, it will automatically find the purifier and attempt to connect to it via WiFi. You only have to select the home router and enter the password.
Now the APP will display the current indoor and outdoor environmental pollution index and other info about the indoor temperature, the active mode, and so on. So you can easily adjust any setting and control the purifier remotely in the real-time.
Generally, the filter can be used up to 145 days. But there is an RFID chip inside the filter that provides a real-time data to the APP, which calculates and shows how long the filter still can be used.
The Xiaomi Mi Air Purifier 2S can automatically detect the pollution of the room to control the wind speed itself. But you can control it manually by choosing any purification range varying from 2 to 39 square meters.
The APP also allows setting timers for starting or turning off the purifier, real-time monitoring and so on.
Xiaomi Mi Air Purifier 2S Performance
This purifier is ideal for rooms with an area of 21 to 37 square meters. But the CADR (Clean Air Delivery Rate) is only 310 square meters. The performance has been tested in a room with an area of 24 square meters. To show the purification effect we lit cigarettes in the room.
After the second lit cigarette, the PM2.5 index reaches 600.
So the purifier switched from the minimum speed to a certain purification speed. After two minutes the PM2.5 index dropped to 400. After 5 minutes of work, it reached 202.
So once the index dropped below 200 the Xiaomi Mi Air Purifier 2S began working way slower.
It took 15 minutes to purify the air and show an index of 64.
After 20 minutes the PM2.5 index dropped to 36. So we can state it takes about 15-20 minutes to purify the entire room.
Xiaomi Mi Air Purifier 2S Power Consumption
There are three modes available to switch between – automatic, sleep, and manual. The first one adjusts the wind speed depending on the air pollution state. So the power consumption can’t be measured for this mode.
The ambient noise is 40dB, while the noise made by the Xiaomi Mi Air Purifier 2S is 41.3dB. The power is only 2W.
Maximum Purification Speed
At its full speed, the noise reaches 74dB. Thus it makes noise that should interrupt sleeping. Fortunately, this speed is enabled only when the room air is too polluted. Finally, the power consumption is 29W, which is quite acceptable.
As we guess, this is one of the best offers if taking into account the price-over-hardware ratio. The Xiaomi Mi Air Purifier 2S is perfect for small rooms. It doesn’t consume much, but it is capable of purifying the entire room in 15-20 minutes. Moreover, it works noiselessly that means you can use it all the time without worrying about your interrupted sleep.
