The most terrible thing in the world for me is that the disaster has come before you are ready. I always thought that only Beijing was the worst hit area by smog. Unexpectedly, I, a small city in the middle of the north and south, would also be hit by smog. It really makes me feel sad. The last piece of pure land is about to be conquered. Compared with the weather, we human beings are too small, But give up? No, haze is nothing! I have "artifact" to help! Haha, it seems to be a bit far fetched. It is true that the situation of smog is serious now, and the number has increased sharply. I don't think it will be long before almost every city will be seriously affected by smog. I believe everyone knows the harm of smog. It seems that there is no other way for us to clean the air except through scientific and technological products. At present, the price of purifier products is high, but the quality is low, It's hard to find a product that is satisfactory. Can Xiaomi Air Purifier 2, which costs 699 yuan, help me drive away the haze? Let's watch the evaluation together!

This Xiaomi Air Purifier 2 is a trial product provided by the Miui Geek Show, so some stains were caused in the packaging during the separate transportation, so I will not shoot the packaging and unpacking parts for you, and will go straight to the topic. I will introduce the appearance of Xiaomi Air Purifier 2 to you. What impressed me most is that the seal inside the package has a touching home appliance, This sentence impressed me deeply. This is what Xiaomi aspires to.

Taking out the dust-proof foam, we can see that the purifier is placed horizontally in the package. According to the actual situation, it took about 2 days to transport the purifier from my hand. During this period, except that the package is a little dirty, there is nothing wrong with the purifier. The compression resistance of the package is still reassuring. In fact, the appearance of Xiaomi Air Purifier 2 is not very different from that of Generation 1, which makes me feel very simple. The whole fuselage of the purifier has many air exchange holes, each of which is in regular order, and looks very clean. The air exchange holes around the whole fuselage are the air inlets, that is, the air begins to be sucked in from here.

Now that there is an air outlet, there is also an air inlet on the top. Purify the air through the air inlet, filter element, and then discharge fresh air from the fan grid of the air outlet. This is the purification process of Xiaomi Air Purifier 2. The design of the body is also very simple. The whole purifier has only one button to operate, that is, the button next to the fan grid on the top.

There are three operation mode indicators in the upper right corner of the front of Xiaomi Air Purifier 2, and these three indicators represent three modes: automatic, sleep, and favorite (custom). The purification capacity of each mode is different, and the noise emitted by the fan is also different. I will give you an in-depth evaluation on the noise problem later.

(A close-up of the air exchange hole of Xiaomi air purifier 2, and we can also see that there is an LED indicator light at the bottom. Xiaomi has designed this indicator light to be the same size as an air exchange hole, which is very creative.)

Xiaomi Air Purifier 2 has an overall height of 50cm and width of 25cm. The compact cuboid design is suitable for any place in the home. Personally, although the overall design of Xiaomi Air Purifier 2 is simple, it gives people an unspeakable feeling. Maybe this is what others call simplicity and beauty.

Let's take a look at the back. The back of Xiaomi air purifier 2 is the filter door and dust sensor. In addition, if the protective cover of dust sensor is opened, the filter door must be opened first. The density of all dust particles in the air must be sensed by the dust sensor! In addition, above the dust sensor are the light brightness adjustment and filter element reset keys.

The dust sensor needs to be maintained and cleaned for a certain time.

The cleaning of the dust sensor and the operation method of replacing the filter element are printed on the filter element door, which is a very practical design, so that users can see it at a glance when using it.

After opening the filter element compartment door, we can see the shape of the filter element into the air purifier. This filter element is also the most critical thing in the whole purification process.

It is very simple to replace the filter element. You can pull out the filter element by gently dragging the gray cloth strip.

There are also some instructions engraved on the shell of the filter element. In addition, it seems that the space in the middle of the filter element can be equipped with a filter element of other effects.

The close-up of the fan inside Xiaomi Air Purifier 2 looks very exquisite. The fan blades of Xiaomi air purifier 2 adopt axial flow fan blades, which can spray the purified air from bottom to top in the form of vortex airflow. According to the set area, it will spread to the whole room at the fastest speed to quickly complete the purification.

The power interface at the bottom of Xiaomi Air Purifier 2 is relatively concealed, which is a very good design, thus greatly reducing the damage of the power cord.

In addition, here's a suggestion. People who are a little poor indoors can hardly see the LED light on the top of the air purifier. So why add a display screen? Although the display screen is not added and the current mode is prompted by LED lights, it is still troublesome for the user to constantly pull out the phone to see the mode and purify the values. Of course, it is easy for us young people, but it is troublesome for older people.

Now let's test how much noise Xiaomi Air Purifier 2 will make after running. First, the indoor noise is 40dBa, which is a feeling that you can't hear any noise at all, that is, the sound in our daily life.

After the automatic mode is enabled, the value is increased to 58dBa, and some noise can be felt at this time. (Note: I found that the exposed power source will reduce the beauty of the photos when I took this group of photos, so I blocked the power line with the packaging box to try to be beautiful! Instead of not connecting the power line!)

After changing to the sleep mode, the decibel meter test result is only 46 dBa, which means that the noise of the air purifier during sleep can not disturb you at all. In addition, the third mode may not be able to make an accurate evaluation, because it is based on your own preferences, so I will not do the decibel noise test, In general, the noise standard of Xiaomi Air Purifier 2 is well controlled.

(Xiaomi air purifier 2 is fully open, red is the worst air quality, orange is average, and green is the best)

Ok, let's take a look at the app! I will not introduce the connection process of the app. You should know how to use rice noodles! It's a simple connection method. After the connection is completed, you can click to see the current air quality and some air data. The third mode at the bottom is the one I introduced earlier. The biggest advantage of the app is to always pay attention to the filter element and the current purification quality. This is an experience that other air purifiers cannot achieve for the time being.

Other operations such as timing on/off, voice prompt, light prompt, etc. can be set. In addition, Xiaomi Air Purifier 2 supports online upgrade, so many small bugs can be solved in time. This is also the advantage of this product. No one wants to buy a garbage product that can't fix bugs in time.

The favorite mode can customize the range of purification space, which can support a maximum of 34~37m. In addition, from this picture, we can see that the air quality has improved. It was 89 just now, and it is 58 now.

However, whether Xiaomi Air Purifier 2 is useful or not, we still have to use a test to talk, so I decided to use a cigarette to test whether the purifier can automatically purify! Ok, now light a cigarette first.

When we pay attention to the APP at this time, we will find that the air quality data is declining from 58 to 79 and then to 96148.

After a while, the air purifier receives more and more air pollution index from cigarettes.

But after a while, the air quality pollution began to decline again, from 168 to 102, which shows that the millet air purifier really achieves automatic purification and intelligent purification! So those black texts on the Internet are broken without attack. What can't be purified? Let me say first, can a large company commit such a naive mistake? However, since there is no professional PM2.5 data detector, it is temporarily impossible to observe the air quality with the mobile phone terminal. If I have the opportunity, I will continue to evaluate such purification capability!

Finally, I also want to make a small test. Recently, many news reports say that Xiaomi Air Purifier 2 can be purified without filter element. Now I will test whether this is true. First, I have removed the filter element, and then turn on the automatic mode to clean for a while.

After a while, when I came back to see it, the air quality of the APP on the mobile phone did not show that it was purified at all, but it improved by 3 points. That is to say, it could not be purified without the filter element. If there was no filter element, the air quality displayed on the APP was declining, then there was a problem. In addition, here is a suggestion. If there is no filter element, the APP still shows that the filter element is 100%. This bug needs to be repaired, otherwise many people will think that even if the filter element is not installed, the residual rate of the filter element can be seen, which is easy to cause users to misunderstand!

Experience summary: Through a series of experiences, from appearance to app to actual purification, I really can't find out the problem with the RMB 699 Xiaomi Air Purifier 2. If I have to find out a problem, I hope to add more color choices. After all, white is too boring. But through this geek show, It also gave me a deep understanding of how an excellent product works. I hope that Xiaomi Company can make more moving household appliances, and also hope that Xiaomi Air Purifier 2 can help everyone to drive away the haze!
