A few days ago, such a picture caught fire on Weibo because the blogger brought a household air purifier of XX brand on the high-speed railway, and in addition to the super smog that enveloped the whole northeast of North China in December, the air purifier, which was not part of daily life, has been hailed as one of the new three major items, and what kind of air purifier is worth more, 352 I will tell you.

The first choice of 2500 -- 352 X80

Packaging&Appearance

352. Although I was prepared, I was still shocked when the logistics arrived. The size of the 352 X80 outer package is almost similar to a small water heater, and the 22.5kg weight can also be counted as a large part of a household appliance. Like many household appliances, the 352 adopts a double-layer packaging design, that is, the outer packaging of the machine has an extra layer of transportation outer packaging, which strengthens the overall protection of the machine body.

After opening the first package, you can see the real guarantee inside, which is very simple. The logo of 352 and X80 are on the top, and the empty product picture is on the bottom.

The product information is marked on the side. It can be seen that the clean air volume (CADR) is 750 cubic meters per hour, and the noise is 37-68dB.

After opening the upper cover, the first thing you can see is a test report. It can be seen that each 352 delivered from the site has been strictly inspected to ensure that each is a qualified product.

Next is the accessories layer, which includes four universal casters (two brake casters), power cord, remote control and user manual.

The user manual is large in font and color printed, and the overall introduction is clear in logic. The elderly and children can also learn it quickly.

It is a very small and thin remote control with a total of seven buttons. At first, I felt a little disappointed when I got it. After using it for a while, I learned that the retention of these seven buttons has condensed a lot of efforts of engineers. It feels good and uses button batteries for power supply.

The standard national standard three item plug has thick and tough wire.

Then there are four universal wheels, the last of which is the brake caster.

Next is the host part. Remove the foam plastic at the top of the accessory layer, and you can see that an important prompt card is attached to the upper panel of the purifier. In fact, it is convenient for those who use the appliance without reading the instructions.

According to the instructions, the first step is to install the four universal casters and power cord at the bottom, which is very easy to install. If your family has bought a computer ergonomic chair, the same is true.

After installation

Snap on the bottom of the side panel

When the machine is upright, you can see the main panel, which is gray and black in color contrast design. There is a display screen and 6 function keys below, and the right side is the power key.

There is a groove on the top, which is officially designed as the storage space for the remote control. But I want to say that the hard plastic has no cushion design, so there should be scratches visible to the naked eye soon, and it is the kind that cannot be repaired. I hope the manufacturer can improve the design in the future.

352 does not have an APP, but has pasted a QR code of WeChat service number in the lower right corner.

Then down are the air status indicator and the air outlet.

352 logo, power status indicator and ebmpaost fan built-in logo.

Dust sensor on one side

The back plate on the other side and the unloading handle are connected by the snap inside, and can be opened with slight force.

The overall diagram after the panel is uninstalled. The following describes the use of each layer.

The top is the air status indicator light and air outlet. This design is also worth thinking about. Making the status indicator light into a downward prominent streamlined shape is not only convenient for blowing clean air around, but also the height of the air outlet is at the height of people's general sofa or seat, which meets the primary needs of the human body. However, the design of upward direct blowing will inevitably lead to loud noise due to high wind resistance when the air volume is large. But this must be the reason why engineers design this indicator light like this. Aerodynamics is more professional. I just want to take you to think about it.

1， H080A high efficiency passenger air filter, with pleated design, is the layer closest to the air outlet, which must be the main force to remove the smallest particles, and can filter PM0.3.

2. High efficiency odor filter T080A, honeycomb design, should contain a large number of effective activated carbon components, which can clear formaldehyde, toluene, etc. in the air.

3， Since the EBM centrifugal fan is not a turbine, the noise is certainly low.

4. Medium and small air filters M080A filter pollutants between the smallest particles and large particles. Like H080A, they are designed with folds.

5. The lowest part is the primary air filter, and the left and right parts are used to filter dust and other sundries.

The three filter elements with models need to be replaced as needed, and the bottom primary air filter can be cleaned on time.

use:

After startup, 352 will automatically detect the air quality of the current environment and show it in the air status indicator light and the power indicator light below. Green indicates good, orange indicates medium, and red indicates poor. Generally, the maximum value outside the room is about 150 PM index. For example, as shown in the figure, the meter has exploded outside on the same day, and the PM index inside the room is 139, Then the air purifier will intelligently adjust the air volume according to the current demand. Of course, you can also manually adjust the air volume, which is divided into six gears: 120, 240, 360, 500, 610, 760 cubic meters per hour.

In addition to manually adjusting the air volume, you can also adjust the operation mode of the purifier. There are three levels: sleep, automatic and rapid. There is no need to say more about automatic. The air volume at night is 120 cubic meters per hour. Turn off all power indicators; Rush is to use 760 cubic meters of air per hour to quickly remove pollutants. Of course, the big air volume will inevitably lead to loud noise.

In addition, you can also close the 352 regularly, but it's a bit incomprehensible that there is no appointment to open it. After all, not everyone will be connected to household appliances 24 hours after leaving home. Baomi must have done a good job in this. Compared with Internet companies, of course, there are light control, copper lock and filter element inspection, which need not be introduced too much.

As for the effect of air evolution, it is impossible to control all variables because it is a personal test. The data and results here are only for your reference. First, let's explain the test environment, Shenyang in Northeast China, one of the major smog areas in China. The haze, which is not easy to spread, becomes more reckless after heating in winter. Although the AQI index reported by the meteorological observatory is only more than 200, it easily reaches the limit of 500 after the individual uses the instrument to measure outside the balcony window, which can also explain why the voice is still uncomfortable at home, and the AQI in the house has reached the moderate pollution level of 139. Well, the book goes back to the original story. The house is a bedroom with an effective area of 20 square meters, which must be similar to the use environment of many people (please detour, just buy more in large space). The air detector measures every minute at a distance of 2 meters from the air purifier. This is because most people's air purifiers must be placed at the end of the bed, In China, the average bed is 2 meters long, so it almost simulates the use environment in daily life. The air purifier uses an automatic gear. The air detector is a master of 360.

Then again, everyone's use will be different. This is just a reference.

352 impressed me deeply. 3524 can be reduced to about 50 in 5 minutes, and even to about 30 in 10 minutes. In the night sleep mode, it can always ensure that the AQI in the room is in the single digits, and the operating noise is also about 30dB (this is also measured at 2m, mixed with the ambient bottom noise).

summary

The test results have been said at the beginning, and will not be repeated. Just put aside the test, there are still many things worth our reflection. Just like the words on the cover of the Leopard rice manual, "I hope one day, we will no longer need the purifier". Let's work hard for it!
