Today, many cities have air quality problems, and the value of air purifiers is becoming more and more necessary. It is difficult for ordinary people to enter the home of purifiers that are often worth tens of thousands of yuan. Xiaomi priced the second generation of air purifiers at 699. Even if he wanted to try, the cost was not high. When an air purifier reaches the second generation, it at least indicates that the reputation and sales volume of the first generation product are good. Xiaomi air purifier 2 can almost be said to be the mini version of the first generation product. What is valuable is that the performance increases without decreasing, and more parts are installed in the smaller body.

-Pure white appearance-

The package of Xiaomi Air Purifier 2 is much smaller than expected. Although its volume of 240 * 240 * 520 is known, it is still surprising to see such a small package, because ordinary air purifiers are not so small and light.

Open the box, and the millet air purifier 2 inside is covered with a protective cover. The linen cloth is relatively thick, which can protect the millet air purifier 2 from being worn during transportation. The instructions on the top are printed with "To be a moving household appliance", which is aimed at moving people. I hope Xiaomi can carry out this idea to every generation of products.

The design of Xiaomi's hardware products is high-end and grand, and Xiaomi's air purifier is no exception. Although there is no metal shell of Xiaomi's mobile power supply, the texture of frosted pure white plastic, made of plastic materials from Samsung, South Korea, and Toray, Japan, is also unknown. Compared with the piano paint surface, the frosted surface of Xiaomi Air Purifier 2 can avoid scratches to the greatest extent during moving.

With the appearance of a square cylinder, the second generation of Xiaomi air purifier is more mini than the first generation in height, and the overall volume is 40% smaller than the first generation. This is due to the fact that Xiaomi air purifier 2 changed the design of the first generation of double fans to single motor+double fans, which greatly saved internal space. The advantage is that it doesn't look so silly anymore. It is smaller and more refined. At the same time, it is easier to move in terms of mobility. This size and weight can be handled by one person.

Xiaomi air purifier redefines the appearance of the purifier. The previous air purifiers look very bulky and have a general sense of design, or are very complicated to create the so-called sense of technology. Xiaomi has created a clean and simple air purifier with minimal effort.

The air inlet is on three sides of the fuselage, and the air outlet is on the top. The air inlet holes on the three sides have a sense of design. They become smaller from bottom to top, just like the change of bubbles from the bottom to the surface. This design can be seen on some speaker products, but it is still very rare on the air purifier. Each air inlet hole is about 3mm, which looks exquisite. All sides are of the same design. The 240 * 240 cube looks neat.

The fan grid of the air outlet is a common design. The color matching is the second color on the body, light gray. This combination of light gray and white is common in Xiaomi products. In the middle is Xiaomi's logo, and on one side is a power switch and wifi indicator light.

The three LED indicators on the side of the fuselage represent the automatic mode (automatically switching the operation mode according to the indoor air quality), the sleep mode (ultra-low noise operation to create a comfortable sleep environment), and the favorite mode (set the use area through the mobile phone app, customize and select the purification intensity).

All LED indicators of Xiaomi Air Purifier 2 are designed to be very small and dim green light, and the light sensor on the body can adjust the brightness of the indicator light according to the indoor light, which is intentional. As a household appliance that may work continuously at night, if the LED is too bright, it will definitely affect the normal rest of users. The air quality indicator light is designed to be only 7.5cm away from the ground, which is far below the height of the user's bed.

Xiaomi air purifier 2 "hides" the power cord in the filter element door at the back, and can be opened with one click. The blue filter screen can be seen inside. According to the data, Xiaomi Air Purifier 2 is still a three-tier purification 360 ° bucket filter design, with Toray H11 high efficiency filter, activated carbon filter screen, and integrated high-quality primary filter screen. At the same time, Xiaomi also provides enhanced filter element for formaldehyde removal, and the formaldehyde removal rate has reached 92%.

The dust sensor and the light switch are above the door. The power interface is more hidden, at the lowest end of the air purifier.

There are four rubber feet at the bottom to fix the fuselage. Xiaomi air purifier 2 is very stable on any plane.

-Air purification capacity-

The most important air purification capability of an air purifier, Xiaomi Air Purifier 2 is equipped with a 9-piece mixed flow fan design, which has the design effect of axial flow fan and turbine fan. It has the advantage of generating large air pressure and absorbing more and farther air. Axial flow fan blades can increase the wind speed. The wind comes in from the side and pushes out from the bottom, thus forming a 360 degree cycle. The air in the whole room can be purified.

The advantage of Xiaomi Air Purifier 2 is that it provides two operation modes. Users can choose whether to use an app or not. As for the Xiaomi smart home app, it is an app that integrates many Xiaomi smart home hardware and can manage all Xiaomi's hardware in a unified way. The connection method is very simple.

The Xiaomi smart home app can first display comprehensive air quality information. The first page is the real-time reference value of air quality PM2.5, as well as the curve changes of filter residue, outdoor and indoor indexes. Pull up to display real-time temperature, humidity percentage, comfort, operation time, purified air volume and other information. That is to say, with the Xiaomi air purifier, we no longer need those detection equipment, because air quality, temperature and humidity can be seen here.

The Xiaomi air purifier 2 can be remotely controlled on the app. The contents that can be controlled include the switch on/off and mode selection. When operating on the mobile phone app, Xiaomi Air Purifier 2 responds quickly, which can be said to give feedback in a second.

In particular, the three modes of Xiaomi Air Purifier 2, the automatic mode and the sleep mode, need not be explained too much. Automatic mode: automatically switch the operation mode according to the indoor air quality; Sleep mode, ultra-low noise operation, creating a comfortable sleep environment; Favorite mode is the most special mode. You can set the use area through the mobile app, customize and select the purification intensity. For example, the area that can be selected is from 1 square meter to 37 square meters, and the wind force is gradually increasing. During the adjustment process, you can clearly hear the sound of the wind force increasing.

For other functions, the alarm of abnormal operation and blue sky can be turned on in the settings, that is, the alarm of good window opening for outdoor air. The light of the purifier can be adjusted to bright light, dim light and off. If users do not like or are not accustomed to using the app, they can also watch the air quality through the air quality LED indicator under Xiaomi air purifier 2. Green is the best, orange is in the middle, and red is poor. The user can also adjust the purification mode according to the indicator light.

As for the purification effect of Xiaomi air purifier 2, after the author started the machine, the air quality PM2.5 index displayed on the app was 31. Start the favorite mode and set it to 22-25 square meters. One minute later, the PM2.5 index dropped from 31 to 26, two minutes later to 22, four minutes later to 16, five minutes later to 10, occasionally showing 9, and then back to 10, almost stable at about 10. Although the sensory perception of the change from 31 to 10 is not very obvious, the purification effect of Xiaomi Air Purifier 2 is very good.
