Air is one of the important conditions for our human existence. In recent years, China has made great efforts to develop its economy while ignoring environmental protection, which has led to a sharp decline in air quality. Especially in the northeast, factories are everywhere to revitalize heavy industrial bases, and the air quality is extremely poor. Two minutes of breathing makes the nasal cavity pitch black. In this environment, it has also promoted the birth of a new industry, the air purifier. This small device filters pollutants in the air through the principle of filter element filtration, providing a pollution-free air space for families or specific semi enclosed spaces. This trial product is produced by Yiliang Technology - Baby Square Air Purifier.

Unpacking and details

Air purification is also a kind of household appliance for users, so the volume is relatively large, which makes the outer packaging must be the standard configuration of the outer packaging of household appliances - paper case. The outside of the package is the caricature style physical picture of the product, LOGO, parameters and other information, and it is also the purification purpose of Babyface air purifier quietly.

The accessories are very simple. There is a trial manual of the device, and the rest is the power cord of the power supply. The 1.5m power cord is also the standard length of the power cord, which is enough for general household use. The standard three plug with input voltage of 100~240V is also a standard input configuration.

The main body of Babyface purification is only 360mm high, which is probably the origin of this product name. Compared with most air purifiers, Babyface purification has the absolute advantage of small size. Most of the purifiers on the market have a usable area of no more than 50 m2, while Babyface purification has a usable area of 30 m2, which is standard.

The control panel of Babyface is in the center of the air outlet at the top. The panel function control adopts LED touch screen. Only the function keys with signs have touch functions. The functions are: mode selection, wind force selection, light on, and the switch on/off key of the equipment. The function is simple and convenient.

The area behind the purifier where there is a removable panel is the VOC and PM2.5 sensor of the baby side. The parts in this area are relatively exposed, so it is forbidden to wash them with water. It is best to clean them with a hand-held vacuum cleaner and a cotton swab, so as to achieve accurate measurement and complete purification.

The baby square adopts the design of up and down separation, which is composed of two parts: the filter center power unit at the bottom and the wind turbine motor system at the top. The baby square can be divided into two parts through the separation button at the bottom, mainly to replace the filter element.

Separate the two parts and look at the bottom of the upper part. According to the official product structure, the wind turbine system in the upper part is composed of BLDC36V motor, motor fixed support, centrifugal 11 blade wind turbine and wind turbine core. The main feature of its design is to provide purification wind power quietly, with power consumption of 1.5W at least and 40W at most.

The filter screen in the lower half is mainly the filter part, which is composed of a 3-layer filter screen system consisting of deodorization treatment screen, pre-treatment screen and HEPA substrate. It mainly removes harmful gases in the air, including formaldehyde, benzene and ammonia. Large suspended solids include hair and fine particles. It can also absorb PM2.5, PM0.3, pollen and other inhalable particles harmful to human body. The air purifier can also be said to be a blessing for patients with pollen allergy. The purification rate of harmful gas is as high as 90%, and the purification rate of particulate matter is as high as 99%. The replacement time of filter element is 4-6 months.

The power module is located at the bottom of the filter element and is powered by four contact current interactively, so the contact must be aligned after each disassembly.

Usage

Infants have adopted two sets of methods for handling and using, one is the direct control of the touchpad, the other is the indirect control of the APP. Let's start with the touchpad control.

Let's start with mode selection. There are two main parts of the touch panel, one is the display module, and the other is the function module. The display module mainly displays the current PM value, as well as the mode and wind force. The display effect is very general, the displayed Chinese characters are almost invisible to the naked eye, and the number of wind force is also ambiguous, which may be the reason for saving costs in this regard, so the display effect is not ideal. The function module includes mode selection, wind setting, screen display and light switch. Mode selection includes four modes: intelligent, sleep, jet and standby. In fact, only the first three modes can be selected for manual control. The intelligent mode monitors the environment according to the PM value. If the PM value is lower than 56, the silent mode, that is, low speed, will be used. If it is higher than 56, the wind will be adjusted according to the size of PM.

In terms of wind power selection, only 1~4 levels of wind power are available. Level 4 wind power is equivalent to the jet mode, which is the highest power level. In daily life, if there are smokers at home, it is better to use level 4 wind power to quickly remove smoke and other harmful substances in the air after smoking. It should be noted that long press of the wind force selection button will enter the device locking mode and then long press to unlock. This function is for the safety of children. The function design is very careful.

There is nothing special to say about the light. Click the switch PM to monitor the light and the touch panel displays the light.

The purification effect of the purifier can be summarized in one word: fast. My test tool is naturally smoke. After smoking a cigarette, the indoor pollution level is catastrophic pollution. It can be seen that the indoor PM value breaks through 400 instantly. In the case of serious pollution, the infant's prompt light is red, and when it drops to general pollution, it is blue, In the normal range, the prompt light turns green, while in a small space of 30 ㎡, it takes about 4 minutes for the baby to reduce the PM value below the normal standard, so the smokers can know the destructive power of smoke. The standard of normal PM value in China is higher than 75, which is not up to the standard. However, WHO (World Health Organization) believes that the PM value below 10 is safe, so try not to smoke in the house. The rise of PM value is terrible.

APP

In terms of APP, the APP side of Babyface air purifier is simplified and biased. For WIFI settings, long press the device mode selection button to make the WIFI indicator light flash. At this time, configure the network. I pondered this for a long time when I first started using it. The sleep mode of the control panel gave me the wrong guidance, which was only understood after reading the manual repeatedly.

After the equipment is connected, the APP function can be used. The function is basically the same as that on the control panel. There is an additional purification time option to select the time to be purified. Here, I hope the manufacturer can enrich the functions of the APP, such as timing switch, setting the time period of the daily timing switch, so that the purifier will not be controlled repeatedly.

summary

My overall score is very high for Babyface air purifier. First, its small size. For ordinary families, the space occupied by household appliances is also an important factor to consider. Second, the diversity of functions and the choice of several modes make this product closer to life. And once it is turned on, it can automatically adjust the purification intensity according to the environment. Finally, APP remote control can control the purifier outside as long as the device is connected to the network. If today's haze PM value is too high, you want to leave the haze if you want to return home. It is convenient to control the purifier outside. Of course, there are also some minor flaws, such as the blurring of the screen display and the single function of APP. However, these are not the main problems of the performance of the purifier. The acceptable price of 2099 is also absolutely worthy of this price. I believe that the public users are also clear in their minds, and it is absolutely the best choice for the infant side of the purifier.
