Under the "Ten Faces of Haze", air purifier emerged as a product of the times. Although we would not like to see it, this industry is booming. Babyface air purifier is a product of Yiliang Technology after its segmentation of the air purifier market. It focuses on use scenarios such as baby room, and has its own targeted design. How do you feel when you use it? Let's have a comprehensive experience together.

The packing box of the baby square is simple in primary color, the thickness and strength of the paper shell are fairly good, and there are barreled foam blocks at the top and bottom, so there is no problem in transportation protection. It is the first time to see a product embellishing the "quality guarantee certificate" with a paper cover. It looks very exquisite, which also reflects Yiliang's confidence in product quality. The instruction manual is large, easy to read, rich and detailed. It is a good habit to read the instruction manual first when unpacking.

The power cord of Baby Fang Kongjing is 1.5 meters, which is normal level. The normal household placement is basically long enough. To be sure, it supports AC 100~240V 50HZ wide voltage, and the power plug is three-phase, which makes it safer.

Because of the positioning of Baby Fang Kongjing, its volume is much smaller than that of our commonly used purifier, with a height of about 37 cm and a width of about 32 cm, which can be called "Baby" in the empty space. The picture below is a comparison with the Yadu Double Sided Hero in my living room. The baby is obviously several sizes smaller.

The baby's empty appearance is white and plump, with a large number of radian designs. The style is round and simple, without any edges and corners. Moreover, the shape of the upper part is small and the lower part is large, plus the anti-skid rubber strip on the base, there is no need to worry about the baby bumping or knocking down during play. It is good that the appearance design fully considers the use environment of product positioning.

In terms of function, the indicators of baby's empty net are VOC PM2.5、 More than 99% formaldehyde and toluene. The VOC and PM2.5 sensors are arranged in the center of the back of the fuselage, and the protective cover is provided with air holes at the top and bottom. After a long period of use, the sensor can be cleaned and maintained with a cotton swab or vacuum cleaner. Although it is not commonly used, the back cover is a bit difficult to open. It would be better if there were special tools available, or the buckle could be redesigned.

The baby side uses 360 degree surround inhalation, and the vertical grille surrounding the lower part of the fuselage is the inhalation part. Therefore, when placing the empty space, keep it away from the wall or obstacles for more than 30 cm, so as to have a better airflow effect.

The structure of the baby square is special, and the replacement filter screen is also special. You need to press the switch at the lower part of both sides of the body, take off the shell, and you can directly see the round filter screen.

The upper body of the air cleaner is the touch screen, air outlet, motor and wind wheel module, and is also the final part of the whole machine. The lower body is the filter screen, suction and power module, which are connected and communicated through metal contacts. It can be seen from the disassembly that the details of the work are very good, and there is no impatience. Moreover, the air outlet is not vertically upward, but blows to the side wall and then bounces upward, so that you do not have to worry about directly damaging the fan after dropping something from the top air outlet.

The filter screen is also the core component of air cleaning, and each manufacturer will pay attention to promoting its own high-tech filter screen. The same is true for Baby Fang, which has a "three-layer professional filter screen system. The first layer is a microfilament pre-treatment screen, which can intercept hair, fine debris and other large suspended solids; The second layer is HEPA filter screen, which is made of Japanese Toray high-density PP and PET materials. It can absorb PM2.5, PM0.3, pollen and other inhalable particles harmful to human body, with an effective filtration rate of more than 99% for PM0.3 and 99.9% for PM2.5; The third layer is the deodorization filter screen, which uses the Japanese prince catalyst corrugated paper deodorization filter screen to effectively remove formaldehyde, toluene, ammonia and other harmful gases. " The front and back sides of the filter screen module in the following figure are the second and third layers of the filter screen system.

The following figure shows the first layer of microfilament pretreatment screen, which can be removed and cleaned for reuse after a long time of use. However, the professional filter screens on the second and third layers of Babyface are disposable like other air cleaning products and need to be replaced after 4-6 months. Therefore, the filter screen determines the long-term use cost of air purification products.

However, there is no purchase link and quotation in the filter accessories column on the official website of Yiliang, and there is no other filter on third-party platforms such as JD and Tmall. Moreover, the round filter screen of the baby square is a special product, which is not suitable for third-party manufacturers now. In this case, I'm a little worried about the cost of later use.

There are two ways to interact with Baby Fang Kongjing. One is to use the touch screen on the top of the machine, which can switch the power switch, the "intelligent, sleep, spray" operation mode, the four speed manual adjustment, LED light display switch and other operations, as well as PM2.5 value, WiFi connection, filter replacement and other prompts. Long press the wind speed key for two or three seconds can also activate the child lock to prevent children from accidentally touching.

A circle of LED air quality monitoring indicator light is designed around the touch screen. Light blue indicates excellent air quality, green indicates good air quality, pink indicates air quality pollution, and red indicates heavy air quality pollution. Moreover, in the intelligent mode, if the air quality is always good, the baby will automatically enter the standby mode to save power consumption. In general, the interaction and display of the touch screen are relatively intuitive, and there is almost no difficulty in starting.

The other interaction mode is the popular mobile phone APP. The operation interaction options are basically the same as those of the touch screen. With more timing options, the filter screen replacement prompt has also been replaced by a life percentage, which is more intuitive. The connection process of mobile APP and Kongjing is much the same as that of other products. The connection process prompts are in place, and the WiFi connection speed is also fast. However, the manual said that it was possible to check the ambient humidity, but I didn't find it.

As for wind speed and noise, I made unscientific tests with anemometers and noise meters. The wind speed test result was 0.3 m/s and the noise test result was 20.3 dB at the level 1 wind speed of the baby side. The impact of wind was almost not felt, and a slight motor running sound could be heard near the machine.

At the level 2 wind speed, the wind speed test result is 1.7m/s, and the noise test result is 21dB. The sound of wind can be heard when the breeze is gentle.

At the level 3 wind speed, the wind speed test result is 3.1 m/s, and the noise test result is 39.2 decibels. With the increase of wind speed, wind noise can be heard clearly.

At level 4 wind speed, the wind speed test result is 5.5 m/s, and the noise test result is 55.9 decibels. The wind noise is beginning to make people noisy.

I smoked two cigarettes in a 15 square bedroom with the door and window closed. In the meantime, the value of PM2.5 in the baby square screen soared from more than 20 to more than 120, and the intelligent mode also gradually increased from level 1 wind speed to level 4 wind speed. After no smoking, after 13 minutes, the wind speed gradually decreased. After the PM2.5 value dropped to 50 safety value, the wind speed became Level 1. In addition, the infant's PM2.5 value began to rise when he vomited his first cigarette, and his response was relatively sensitive.

In a word, Babyface has accurate positioning, compact and smooth body, a nominal applicable area of 30 square meters, excellent wind noise control, simple and effective operation interaction, and is very suitable for use in the bedroom. The only concern now is the cost of the filter screen used subsequently.
