Introduction

I believe that you are still very impressed with the documentary film "Under the Dome", a public interest survey on air pollution two years ago. Chai Jing, the host who left CCTV, shot this large-scale documentary at his own expense, which revealed in detail and deeply the serious damage of haze to our lives. Every year in late autumn and early winter, Tianjin, the northern city where the nap is, will be shrouded in such a cloudy weather. There are countless babies who wear masks when going out, dare not open windows at home, and have colds and coughs in children's hospitals; The reason is that whether it is a large number of automobile exhaust emissions, industrial pollution in Tianjin, Beijing and Hebei, or the trend of desertification in the north, these are beyond the intervention of ordinary people; Although "APEC Blue" and "All Transport Blue" have occasionally appeared, we have to say that our living environment and health index have become increasingly severe. If we want this situation, we still need the intervention of the national government. What we can do is to minimize the damage caused by this environment.

This 352 X50 air purifier is a daily necessity created by Beijing 352 Environmental Protection Technology Co., Ltd. with the idea of returning healthy breathing to each user. The product appearance design maintains the concept of simplicity, and the characteristics of small size and high appearance can be perfectly integrated with the modern home environment; In terms of performance, CARD value up to 500m ³/h, H13 grade high-efficiency filter paper, 950g activated carbon, low noise and power saving, APP remote control and many other characteristics can be regarded as the benchmark of the air purifier industry, providing a layer of health protection for home life. The new house in the nap home was decorated some time ago, because there is a 10 month old baby at home, which has been in the stage of putting off flavor. In order to move to a new home earlier, choosing such an air purifier can not only filter the air effectively, but also reduce harmful decoration gases such as formaldehyde, creating a healthy growth environment for the baby.

Simple unpacking: simple appearance and small floor area

First of all, thank you Love to play computer games Valuable evaluation opportunities given by the platform; The 352 air purifier is packed in an environmentally friendly cardboard box with thick foam inside for protection, which can effectively protect the collision during transportation. The drawback is that there is no slotting design on the surface of the box, which makes it difficult to carry. The "efficient, intelligent and silent" on the surface of the box is also the best summary of the performance of this product.

On the top of the open package is all the accessories of the purifier, including power cord, remote control, user manual, warranty card, APP installation guide and a quality inspection certificate. In general, the accessories are in good order, and the configuration of the remote control is a highlight; In addition to controlling the purifier through the control buttons on the body surface and the mobile phone APP, it can also be realized through this small remote control; It is very convenient to sleep at night without having to switch on or off the machine or adjust the working mode of the machine when getting out of bed.

On the quality inspection certificate, the air volume values of different gears of X50 purifier were actually tested, and the product was inspected by comparing the standard air volume with the allowable range. The air volume from 154m ³/h in gear 1 to 510m ³/h in gear 5 is strictly controlled, and the data is recorded by hand, which shows great care. In the instruction manual, the performance parameters, control panel, machine maintenance and precautions for use of the purifier are clearly described, and users can read them carefully before use.

The front and back of the 352 X50 air purifier are displayed. The whole body of the machine adopts milky white and gray as the main colors for matching, and there are no too many decorative elements on the surface; The front gray panel seems to have the effect of a longitudinal metal wire drawing process, but the actual material is still plastic. The milky white shell on the back is also frosted, which feels good. On the whole, the shape of this purifier maintains a simple and fashionable style, which can be integrated into various styles of home effects. The overall dimension of the machine is 310 * 310 * 763, and the small size covers an area of less than 0.1m ³, which is very suitable for small family use. The whole machine weighs 11kg, but it is inconvenient to move because there is no wheel design at the bottom.

It is believed that before the user buys a desired air purifier, the performance effect is an intuitive factor to measure its cost performance, especially the purification capacity and control mode. The concept of clean air output ratio, the so-called CARD value, should be popularized here. It is also an intuitive reflection of the performance of air purifier products. The larger the clean air output ratio, the higher the purification efficiency of the purifier. The CARD value of 352 X50 is 500m ³/h, and there is a formula that the area S (square meter)=12F/60H, where F is the CARD value, and H is the room height (generally 2.7m); The calculated trial area of X50 is about 35.7m ³, and the official trial value is 35-60m ³, which also takes into account the effective volume of the room and other factors. That is to say, this product can be used in our bedroom, study or living room with larger area. For the performance test of the X50's purification effect and power consumption, the nap will be tested in detail in the following chapters.

Talk about details: ingenious process, simple operation

An air purifier suitable for home life should not only have outstanding appearance, but also its performance is more important. As the saying goes, details can be found in the real chapter, and every industry has its own unique performance. For the 352 X50 purifier, the hardware determines the hard strength of a product, and the design of its details determines whether consumers have an impulse to buy at a glance; Let's take a closer look at this product from the product details.

1. Air inlet and outlet, three in and one out more efficient

First, let's take a look at the air circulation mode of the X50. Both sides and the back of the fuselage are designed with louver shaped air inlets, which can ensure that the surrounding air enters the purifier at a large flow rate for filtering; In use, it should be noted that the distance between the three air inlets and the wall should be more than 30cm to avoid affecting the air intake. The design of the air outlet is more artistic. Instead of using a hollow structure, it uses a mesh grille effect as the air outlet. The visual effect is more beautiful. In brief, the purifier is the process of pumping air into the interior through the following three air ducts, filtering the filter element and then flowing out from the top to form a 360 degree air vortex, gradually purifying the indoor air.

2. Display and control, PM2.5 data is intuitive

The black area on the front panel of the machine can digitally display the PM2.5 value in the surrounding environment, so that users can have a more intuitive understanding of their living environment. As the purifier works, the value will also decrease and change in real time. Unfortunately, there is only PM2.5 on the display panel, and there is no formaldehyde, air temperature, humidity, PM10 data display. It is recommended that the manufacturer can add relevant sensor detection equipment. Data such as temperature, humidity, and formaldehyde are still critical for families with small children. Below is the 352 metal LOGO and an X shaped working status indicator light, which is orange in standby and green in operation, giving the impression of an X war alarm sign.

The upper surface of the machine contains all the control keys and the working status prompt chart, and the keys are realized by touch. Including power key, mode key, child lock key, light key and air volume adjustment key; The display area can remind the working mode (automatic, sleep, rapid), WiFi connection status, filter life, linkage status, etc. In general, the control of the X50 is very simple, and it is also very convenient for users to use it. The functions of the machine itself, the remote control, and the mobile phone APP are the same. For the three working modes of the purifier, they are differentiated by the size of the air volume. The purification effect will be fast under the extreme speed mode, but the noise is relatively large; Automatic mode is automatically adjusted according to the monitoring value of PM2.5; The sleep mode windscreen will be low and the noise will be low.

An LED light source is designed on the rear side of the control panel, which can not only be used as a night light at night, but also as an indicator of air quality. If the PM2.5 value in the environment is high at the beginning of startup, the red light indicates poor air quality, and the orange light indicates average quality. After purification for a period of time, the green light indicates good quality.

3. Core component, H13 filter element

The X50 is equipped with a semiconductor laser detector and a micro sampling fan behind the machine, which can detect particles and dust with a diameter of less than 0.1 μ m and ensure the accuracy of PM2.5 numerical detection. The sensor can be disassembled to facilitate subsequent upgrade and replacement. In this case, why not add formaldehyde, temperature and humidity detection sensors?

The replacement and removal of the filter element are also simple. The air inlet at the back of the machine is actually a removable cover plate, which can be easily removed through the upper hand buckle. A contact switch is designed at the connection part of the cover plate, which means that even when the purifier is working, opening the cover plate will immediately cut off the power supply to ensure safety. After opening the cover plate, you can see the white barrel shaped filter element. There is a stretch switch below. When you stretch the filter element outward, it will drop a short height. Drag the pull cord to take it out. The back of the cover plate is also provided with the disassembly and installation diagram of the filter element, which is convenient for users to view.

352 X50 is a mechanical air purifier product, which is simply to filter the air through a fan and a filter element; The performance of the fan determines the rate of air purification, and the quality of purified air depends entirely on this seemingly simple barrel filter element. The X50 uses the H13 level HPEA filter screen, so we have specially popularized the science for this nap. The X50 filter core is composed of three parts: the first is the outermost plastic woven plain mesh, which mainly serves to fix the filter paper in the middle and intercept the larger particles in the air; The second middle layer is 4 square meters of H13 filter paper. As for the concept of H13 nap, I will not talk about Baidu's introduction here. If you are interested in it, you can find out about search by yourself. In short, H13 is not the best. Maybe the manufacturer takes more price factors into account. The last layer is to add 950g activated carbon between the filter paper and the internal iron mesh, which can adsorb organic gases such as formaldehyde in the air.

The X50 integrated filter element can be said to have both advantages and disadvantages. The advantage is that the replacement is simple and the price is believed to be relatively cheap, but the degree of air separation may be inferior to the more high-end product (multiple separation design filter element). Many netizens may not know much about the performance of the filter element of the air purifier just like the nap, but the emergence of domestic air purifier products such as Xiaomi and 352 in recent years has really broken people's fear of the price of the air purifier. Some people may say that more than 1000 products are absolutely incomparable with more than 10000 purifiers, but after a nap, they think it is enough for ordinary people to use such products with higher cost performance.

4. Streamlined appearance, elegant and fashionable

The outline frame of the X50 is a highly circular arc structure. The streamlined line transition not only has a fresh and beautiful visual effect, but also ensures safe use. For those who have babies at home, such as napping, they are most worried about the products with marginal corners. It is very dangerous for children to bump into them carelessly.

Test performance: PM2.5 purification effect is obvious, formaldehyde effect is slightly poor

The next step is to actually test the performance of the 352 X50 air purifier. As we mentioned earlier, the new house for nap has just been decorated, so the test environment is put in the new house. Before the test, all the windows of the house were closed for two days to let formaldehyde, wall emulsion paint, cabinets and other pollution source gases release and remain, and the comparison effect will be more obvious.

The main equipment used in this test includes 720 environmental reports (mainly testing formaldehyde, PM2.5 and PM10), 360 air detection master (testing PM2.5), decibel tester (testing the operating noise of the purifier) and electricity power meter (counting the energy consumption of the purifier). As the saying goes, a mule is pulled out by a horse. Next, we will experience the performance of the X50 through multiple test environments and multiple sets of test data. The purifier uses extreme speed mode, which can evaluate the best performance of the purifier.

1. Living room test (PM2.5)

The total area of the living room and dining room of the new nap home is about 40 ㎡. During the test, the doors and windows of the dining room, bedroom and bathroom were closed. In order to highlight the effect of the air purifier, the nap also smoked a cigarette in the living room.

It can be seen that the value on the screen of the purifier is 458 μ g/m ³, and the value displayed by 360 Air Testing Master has been in the burst state (500 μ g/m ³). It seems that the PM2.5 brought by smoking is really amazing, and it is also very harmful to children. In the future, we should make up our minds to quit taking naps.

After 5 minutes, PM2.5 dropped to about 200 μ g/m ³, and after 10 minutes, the value dropped to about 100 μ g/m ³; It is good to have such a fast purification efficiency in a space of 40 square meters. When PM2.5 reaches 200, the purification rate begins to decline.

After 30 minutes, the PM2.5 value in the living room dropped to 27 μ g/m ³, and the status indicator of the purifier turned green. In general, it takes quite a long time to purify the air pollution caused by a single cigarette. If it is used in an ordinary home environment, the PM2.5 in the room air is about 100. In the extreme speed mode, it takes about 10 minutes to reach a healthy level, and the speed and effect are very good.

2. Master bedroom test (formaldehyde)

Next, test the purification effect of the master bedroom. The size of the room is about 25 ㎡. Because the wall of the room has just been painted with latex paint and the newly customized wardrobe and other furniture, the formaldehyde content must exceed the standard. Because the main function of the X50 is to filter PM2.5 in the air, the purification effect of formaldehyde was not good at the beginning of the nap.

PM2.5 in the master bedroom was 53 μ g/m ³ before purification, which was basically kept at a normal level. The formaldehyde content in the room passing the 720 Environment Treasure test is 0.12 ㎎/m ³, which is already in the danger level. After the purifier worked for half an hour, the content dropped to 0.08 ㎎/m ³, and after one hour, it reached a healthy level of 0.05 ㎎/m ³; It seems that the purification effect of X50 on formaldehyde is also good, but this is only the test result in a 25 ㎡ airtight room. If you want to use it to purify the formaldehyde in the whole house, it is still very laborious. In addition, it takes time to remove formaldehyde, so it will be better to have more ventilation and windows.

3. Secondary recumbent test (PM2.5, PM10)

The last room tested was the second bedroom, about 15 ㎡ in size; Before the test, the ground was cleaned after a nap. The values of PM2.5 and PM10 were 150 μ g/m ³. After opening the purifier for 5 minutes, the values dropped to 10 μ g/m ³. It seems that the purification rate of a 15 ㎡ small room is amazing.

Through the display panel of X50 purifier, you can also visually see the change of purification value; According to the test of three environments, this purifier is suitable for use in a single room, with an area of 30-40 m2. The filtration of PM2.5 or formaldehyde harmful gas is very good, but the use environment of larger units may be a little inadequate. Taking a nap is to prepare to put the X50 on the second bed where the baby will live, which can bring more healthy air to the growth of the baby.

4. Electrical performance test (noise, power consumption)

The above two groups of data are measured by the decibel tester at a distance of about 1 meter from the purifier, and the noise conditions of the X50 under extreme speed mode and sleep mode are 57.8 dB and 44.8 dB respectively; Basically, it is close to the official data. Sleeping at home in the daytime or at night will not affect normal life.

The above two groups of pictures show that the power consumption meter tests the power consumption of the purifier in the extreme speed mode and automatic mode. The power consumption in the extreme speed mode for one hour is 0.034 degrees, so it is 0.82 degrees in 24 hours a day; The power consumption of the purifier is 0.082 degrees after 12 hours of continuous operation in the automatic mode. At this time, the power of the purifier is 6.8W. It can be seen that the power consumption of the purifier will also decrease with the improvement of air quality in the automatic mode, saving power for users.

Find out the highlight: smart APP, which can be purified before going home

One of the highlights of the X50 is the addition of the smart WiFi module, which can remotely start and adjust the purifier through the mobile phone APP, so that the purifier can be turned on on the way to work, and the room is already a clean air environment when you get home. Download and install the "352Air" software APP through the QR code or app store on the manual, and bind the WiFi in the home according to the purifier model. The whole process is very simple, and you can operate according to the steps prompted by the software.

The main interface of the APP is simple and clear, basically covering all control functions on the operation surface of the purifier, including power switch, air volume adjustment, mode selection, light status and real-time display of PM2.5 values. The software can also plot the working condition of the purifier into a curve, which can be displayed in real time, hours and daily time periods, so that users can understand the changes of air quality in their homes.

In addition, the software also has some common basic functions, such as message notification, fault repair and online shopping mall; Because the X50 product has just come into the market, it is not yet available to purchase the filter element. After a nap, I inquired about the filter element of the official purifier, which can normally work for about a year. By then, there must be an X50 filter element in the mall, and the price is about 299 yuan.

Set up a scene: versatile, suitable for living room, bedroom and study

The X50's own beauty is relatively high. With simple lines, small floor space, and fashionable scientific and technological texture, it can be placed in the study, living room, or bedroom. With some smart appliances and furniture in the home, it can not only bring a clean air, but also improve the home style.

summary

About this 352 X50 evaluation post, the nap has brought so many things to everyone. There may be some things in the article that are not detailed or the evaluation is not comprehensive. Please comment and correct more. In general, because of its fashionable and simple appearance design, as well as its excellent purification effect on PM2.5, efficient speed, low power consumption and many other characteristics, this purifier, as a necessary household appliance for northern families, is sure to have a good sales market space. Especially for families like napping, which have just been decorated and have babies at home, it is necessary to have such an air purification equipment.

In the evaluation process, Nap also found several shortcomings of the product, which are summarized as follows. I hope the manufacturer can consider the suggestions of the small editor.

1. There is a lack of pulley at the bottom of the purifier, so it needs to be lifted to change the use environment, which is relatively difficult.

2. The purification effect of the purifier on formaldehyde is average. I hope the manufacturer can make some improvements on the filter element. After all, formaldehyde is also very harmful to human health.

3. The display panel only has the value of PM2.5. I hope more detection sensors will be added to display the temperature, humidity and formaldehyde of the air in real time.
