In recent years, Xiaomi has continuously expanded its product line. Since the introduction of intelligent routing into the field of smart home, it has successively launched a number of smart home products with high cost performance, such as smart TV, water purifier, air purifier, and so on. These products used to be traditional home appliance enterprises. As an Internet company, The huge price advantage of Xiaomi has obviously caused great pressure on traditional manufacturers. A few days ago, Xiaomi Air Purifier 2 had just been released, and it was revealed on the Internet that the APP was fake, which was proved to be malicious smear after actual measurement, which on the contrary caused more attention to this new product.

So whether this air purifier has real material, what are its features and characteristics in use, and whether it is suitable for your family? Let's see the evaluation of Bug.

Unpacking: product style and 1 Come down in one continuous line from generation to generation

As we all know, the new regulations for air purifier products will be released on March 1. All manufacturers have started the promotion and goods dumping mode at the end of the year. Xiaomi Air Purifier 2 is also on the hot line in this gap period. The nominal CADR value of 330m3/h and the noise value of a single fan are as low as 31dB. The price is only 699 yuan. The price performance ratio is the same at the moment. It is reasonable to sell out of stock.

Kongjing Generation 2 still uses millet style packaging, which can be easily lifted through the top handle, while stacking and unpacking are horizontal, which can ensure safety and facilitate opening.

It is worth mentioning that the one-time damage sticker is used for sealing, which seems to be more common on the digital camera packaging box, and the anti-counterfeiting effect is very good.

There is also a layer of cardboard when opening the box cover. The method of taking out the filter element and power cord is printed. Inside the box is the host computer clamped by two pieces of foam. The document package is pasted on the protective bag of the host computer to make a touching household appliance. The first impression of Slogan is very warm, but it can be touching only if the product is really good.

The host uses a non-woven dust-proof bag to avoid scratches, and this bag can be used as a storage bag to play a certain dust-proof role in daily use.

There are many quick guides, instructions and San Bao certificates in the document package. The style is still typical of Xiaomi's simplicity. Although the operation and use of the machine are not complicated, it is recommended to read them carefully before use.

The overall style still follows the characteristics of a generation of products. The simple square column appearance and matrix dot holes, although not stunning, are more compact and unique, and match most of the decoration styles.

Details: beyond the level of this price

The overall panel of this product adopts the main color of warm white, matched with gray decorative color, slightly frosted feel, and few buttons. All the designs reflect the characteristics of simplicity and ease of use, and the workmanship of each detail is quite up to standard. At this price, it is also a conscience.

The air outlet at the top is designed with sunflowers, but children's fingers can be extended in the larger area outside. If there are children at home, be sure to avoid being injured by the wind blades.

Wifi indicator light and mode switch button are set at the front right corner of the top surface, and mode status light is designed at the top right corner of the front surface.

The whole front and the lower half of the two sides are full of air inlet mesh, while the environment status light is designed at the middle and lower part of the front mesh, and the back is equipped with a light adjustment key, a sensor compartment, and a rear cover. Considering that the purifier is generally placed against the wall, the rear cover is only designed with a solid cavity decoration.

The cover can be opened and closed easily through the rear cover switch. The power cord of the new product is placed in the purifier compartment. It is more intimate that the schematic diagram of replacing the filter element and cleaning the dust sensor is printed on the back of the rear cover

The filter element is designed with a handle, which can be easily pulled out. The elderly can also easily replace it. The disc at the bottom of the cabin is slightly elastic, ensuring the sealing of the filter element.

The filter element of the air purifier is directly related to the use effect. The filter element of Xiaomi Air Cleaner 2 is composed of PET primary filter screen and H11 HEPA filter screen. It can also be replaced by the formaldehyde removal filter element with upgraded catalyst activated carbon layer. This universal design allows the equipment to be used more flexibly. The filter element is also printed with a record of the initial use date, which can be filled in by yourself, It is also a small detail.

The rubber seal ring is used at the connection of the fan on the upper part of the filter element compartment to ensure that there is no gap between the filter screen and the fan. The fan blade is composed of 8 blades, which is quite stable in operation. The single fan design makes the purifier smaller in shape and lower in energy consumption.

The buckle of the dust sensor compartment is located in the filter element compartment, which is easy to open. The yellow knob of the internal sensor can be turned with a screwdriver for sensitivity adjustment. It has been calibrated in the factory, and generally does not need to be moved.

Anti slip pad is designed at the bottom of the purifier, which is relatively stable. The power interface is located at the back of the bottom. The quality of the power cord is good, and it also includes a rubber band. Anyone who has bought Xiaomi patch board and other products knows that this seems to have become the standard configuration of Xiaomi.

Experience: simple operation, but not simple functions

Xiaomi Kongjing 2 has only two physical buttons, and has basic mode switching and light switching functions. Other operations and settings are carried out on the APP. This design reduces costs on the one hand, and on the other hand, it also conforms to the positioning of Xiaomi's smart home product ecological chain.

Connect the air purifier through the mobile phone APP Xiaomi smart home. Under the same LAN, it is easy to face. If you have used Xiaomi smart home products, you will be more handy. Xiaomi has already lost a big part of its rivals in the development of the smart home product ecological chain, and will introduce the application of the smart scene of Kongjing 2 in detail later.

The whole APP interface actually inherits the style of MIUI. For Xiaomi mobile phone users, this overall feeling adds a lot of points to the experience, but what really brings surprises is the humanized function settings, such as timing on/off, various reminders, prompt tones and light brightness settings, Turbo mode, intelligent scene, etc. are very practical in practical use, but the latest learning mode seems to have to be enhanced in intelligence, and sometimes inexplicable settings are recommended.

The graphical status display of the main interface is slightly simple. There is basically no historical data query, while the indoor and outdoor PM2.5 trend curve is better than nothing. The three modes have their own characteristics. In the sleep mode, the interface background will turn blue, while long pressing the favorite mode can enter the setting of large and small purification space, which can be adjusted according to their own use environment.

When it comes to air purification, the principle is actually very simple. The particulate matter inhaled into the air purifier is intercepted through the filter screen to achieve the circulating filtration of indoor air. The removal rate of most purifier products is measured under the ideal closed laboratory environment, which is of little practical significance. Insects use the phantom air box to detect five PM2.5 values at the air inlet and outlet of the air purifier respectively, The results show that most of the PM2.5 at the air inlet is about 110ug/m3, and the air quality is relatively poor. The PM2.5 at the air outlet is between 2 and 20ug/m3. Of course, this only means that the PM2.5 at the two points of the air inlet and outlet is significantly reduced. The filter effect of the purifier is good.

For the purification of the whole indoor air, it has a lot to do with the use environment. For example, there is a lot of dust in the room, or there is no ventilation for a long time, then after the air purifier is turned on, the dust and fine particles left on the walls, floors, furniture and corners may be raised, and indoor PM2.5 will increase temporarily, while the indoor airtight environment is not good, which will also make the purification time longer, Bug opened the window and opened the purifier for testing. Even if the CADR value of this purifier reached 330m3/h, the indoor PM2.5 did not improve significantly. However, if the doors and windows were closed, the indoor PM2.5 would begin to decline about one hour after the automatic mode was opened. If the Turbo mode was used, the purification speed would be faster, but the noise would also be greater.

Smart scene: the essence of killing a crowd of high-end goods

As an enthusiast of smart home products, XiaoBug has used many smart home products, but the best integration of the ecological chain is XiaoMi. Take XiaoMi air purifier 2 for example, it can be linked with other smart home products in the home through APP, especially the Xiaomi smart home package, which contains a variety of sensors and wireless switches, It can be used together to maximize the effect.

Select the built-in recommended mode through the APP intelligent scene, or add it by yourself. Here, select the three scenes above for linkage test. Scene ① click the wireless switch to turn on the purifier, Scene ② double-click the wireless switch to turn on the sleep mode of the purifier, Scene ③ automatically turns off the purifier at the set time.

The above scene demonstrates such a life scenario. The air purifier is placed in the bedroom, the wireless switch is placed in the living room and the bedside table. Before going to bed at night, press the wireless switch in the living room, and the air purifier is turned on. When going to bed, press the wireless switch of the bedside table twice, and the purifier enters the sleep mode. After getting up in the morning, the air purifier automatically shuts down, Of course, there are many intelligent scene modes, which can also be linked with the door magnet and the human body sensor to realize the automatic window opening and closing purifier, or someone can automatically open the purifier in the sensing area and automatically close the purifier after no one passes by. In short, there are quite a lot of intelligent scene functions and usages, which are also very strong, provided that you have to use them flexibly, This may be the essence of all functions of Xiaomi Air Purifier 2.

Advantages, disadvantages and suggestions

From the perspective of actual use, Xiaomi Air Purifier 2 basically meets the needs of ordinary users, and its obvious advantages are as follows:

1. The appearance is not brilliant, but compact and simple, suitable for all kinds of home decoration styles;

2. The APP function is simple and clear, the setting is not complicated, and it can be controlled remotely;

3. The application of a variety of intelligent scenarios improves the intelligence of the product, which is easy to use;

4. The filter element is easy to replace, and can replace the formaldehyde removal filter element, with strong versatility;

5. Compared with similar products on the market, the price of 699 yuan is not high and the cost performance ratio is acceptable.

However, as a cost-effective product, it still has some shortcomings and needs to be improved in terms of functions and various details:

1. The light key is designed on the back, which is slightly inconvenient to operate. It is recommended to adjust it to the top of the front;

2. When the air volume is turned to the maximum, the purification effect is improved, but the noise is still a little high. It is recommended to adopt a better noise reduction design;

3. There are few buttons on the machine. It is recommended to add a remote controller for local use;

4. There is no complete historical data record in the APP, and the sensor detection data cannot be viewed when the APP is powered off, so it is impossible to automatically power on when PM2.5 is detected to be too high. It is recommended to add these functions iteratively as soon as possible;

5. Add voice broadcast and control functions to make it easier to listen to and operate the indoor environment more intuitively without turning on the mobile phone;

6. Since the formaldehyde removal filter element can be replaced, it is recommended to add TVOC and formaldehyde concentration sensor accessories, which can be connected with the air purifier through Xiaomi smart home.

epilogue

In general, Xiaomi air purifier 2 is not as versatile as other high-end purifiers, nor is it too gorgeous. But if you want only one air purifier with simple operation, convenient maintenance, remote control and scene linkage, the most important one is not expensive, and the effect is good, Then Xiaomi air purifier 2 will be a good choice.
