On November 8, Xiaomi low-key launched a new air purifier product - Xiaomi Air Purifier 2S on its official website. From the appearance, there is little difference between Xiaomi Air Purifier 2S and Xiaomi Air Purifier 2. The biggest difference between the two is that Xiaomi Air Purifier 2S has one more OLED display screen than Generation 2. In terms of parameters, the specifications and data displayed on Xiaomi's official website are basically the same. Is the difference between the two just that 2S has an additional OLED screen? In addition to this screen, where else has the 2S been upgraded? Now let's experience this Xiaomi air purifier 2S.
appearance
Open the outer package of Xiaomi air purifier 2S, and you can see that there is a body of Xiaomi air purifier 2S and its instruction manual. Xiaomi air purifier 2S does not need to manually assemble the filter element, and it is ready to use immediately. Its power cord is placed in the filter element bin like the 2nd generation.
Millet air purifier 2S adopts the same long barrel design as Generation 2. The body size of both is 240mm × 240mm × 520mm. The weight of 2S is slightly lighter than that of Generation 2. The 2S weighs about 4.5KG (including filter element), and Generation 2 weighs about 4.8KG (including filter element).
The body of Xiaomi air purifier 2S is mainly made of plastic, and the air inlets are distributed in the lower part of the body. The tower air circuit design is adopted, which can provide 360 ° efficient air inlet purification. The filter element inside the fuselage is Mijia air purifier filter element, which adopts 360 ° integrated barrel design, and is equipped with two layers of filter screens (primary filter screen: filtering large particles; the second layer of Japanese Toray H11 high efficiency filter) and one layer of activated carbon.
The biggest difference between Xiaomi Air Purifier 2S and Generation 2 is that the former is equipped with a round OLED display screen, which can display information such as mode, PM2.5 value, humidity, temperature and WiFi status.
experience
Xiaomi smart products have always adopted the main color of off white. The off white Xiaomi air purifier 2S can be well integrated into the home scene when placed at home.
Xiaomi air purifier 2S uses Mijia App. In the App interface of the air purifier, the most concerned indoor air PM2.5 value occupies a large screen. The author (Mo Changyou) lives in Shenzhen, where the air quality is very good. Xiaomi air purifier 2S measured that our office indoor PM2.5 value is only a single digit.
In the main interface of the air purifier app, we can see more data: the remaining use percentage of the filter element, the remaining usable days of the filter element, temperature, humidity, geographical location and other related information.
In fact, the App interface of Xiaomi Air Purifier 2S is very simple. In addition to the data display, it has only four actual function keys (on the bottom bar). From left to right, there are the On/Off key, the Automatic Mode key, the Night Mode key, and the Favorite Mode key (Power Mode).
Automatic mode
Night mode
Favorite (strong) mode
In terms of noise, we tested the noise of Xiaomi air purifier 2S in three different modes, and its noise performance is basically the same as that of Xiaomi air purifier 2. Since the current air quality in our environment is relatively good, the noise of Xiaomi Air Purifier 2S in the automatic mode is only 40+dB from the night mode when the PM2.5 value is 60+, which is within the normal and acceptable range. Such noise will not affect our daily life and work.
When we turn on the favorite (strong) mode, its sound is obviously more than that of the night mode. The noise test result is 70+dB, which is loud and already belongs to the category of noise.
The official CADR value of Xiaomi air purifier 2S is 310m ³/h, which is consistent with the second generation. During the test, we selected a room with an indoor area of about 12 m2 as the test environment, and the PM2.5 value in the room is 30+. Then we lit a Marlboro double explosive cigarette. When the cigarette burned out, the PM2.5 value in the room had reached 500+.
In the actual test, in a room of about 12 square meters, the millet air purifier 2S can reduce the PM2.5 in the room from 500+to about 100 in about 10 minutes. This process is relatively fast, and it takes about 17 minutes to really reduce the PM2.5 in the room to the initial state (before smoking, the PM2.5 in the room is 34).
summary
On the whole, Xiaomi Air Purifier 2S is not very different from Generation 2, especially in terms of its air purification capacity, which can be said to be the same level. The main purpose of this OLED screen on the 2S is to make it easier for users to understand the indoor air conditions more intuitively and quickly. It is left to click on the mobile phone App to view this step.
After all, Xiaomi Air Purifier 2, which costs 699 yuan, is very cost-effective, and the extra screen of 2S can really bring a better user experience. As for the upgrade value, is it worth paying 200 yuan more for it? Different people have different opinions.
