The news that swept the home appliance circle and the technology circle last week was definitely the autumn release of the hammer on November 7. At the meeting, not only the nut Pro2 mobile phone but also the breathing air purifier was introduced.
Telling the truth, as a home appliance editor, I have always kept the home appliances introduced by technology companies. In the usual purchase and recommendation, I also pick some professional brands with strong professionalism. I think an air purifier first The skills you need should be: Purify the air! All other functions are built on the ability of an excellent air purifier, otherwise everything is empty talk.
The official data of this breathing air purifier shows that the most important feature is that the CADR value is as high as 800+. No matter whether it is PM2.5, formaldehyde or pollen, it can be cleaned up.
In addition, the official also said that in addition to excellent purification capabilities, the air-purifying air filter CCM reached 50,000+mg, formaldehyde CCM reached 4000+mg, far exceeding the new national standard. At the same time, there is excellent noise control and high-quality filter elements with high dust holding capacity. More functional and sophisticated intelligent control, good-looking but not rushing versatile design. The performance of the 10,000-yuan machine is only 3,499.
I am used to the various flicker of the company, I have doubts about the effect of this breathing air purifier. This week, this "Net Red" product came to the China National Grid Evaluation Center. Let us pass the actual test to see if the "passer-by" user is not worth buying.
Minimalist versatile look
The first feeling of getting a good breath air purifier is to be honest. Although the weight is not small, the workmanship is very meticulous, using a simple white design, the overall simple and round, very close. There are no complicated buttons, the function keys are mostly at the top of the front, and the working mode is switched by pressing the “Mode†button at the top, including speed, sleep, auto and manual. The child lock button on the right side of the mode requires pressing the mode button and the switch key at the same time. The filter indicator sounds when the filter needs to be replaced.

The switch and WIFI button are on the back. Download Chang breathing APP, long press WIFI can hear the sound of "drop", connect in the 2.4G network environment, the connection process is smooth, compared to some used smart home appliances, I think the hammer in the APP connection and experience well done.
The mobile phone interface not only displays indoor air quality, but also the air quality of the user's area.
The operating mode of the air purifier can be switched by the bottom button.
You can also use the APP to modify the purifier name, turn off the display, and switch the child lock button, which is much simpler than before by pressing the key + mode button.

Ultra-high purification efficiency stems from solid workmanship
To achieve a CARD of more than 800 m3/h, the air purifier must have an excellent motor, a high air volume, and a low-noise air duct to match the high-efficiency filter.
Let's see how breathing is done:
It uses a high-quality DC brushless motor with a life of up to 20,000 hours. It adopts a backward centrifugal wind wheel and a three-side air inlet top air outlet in the air duct design, which provides a more abundant air volume for the air purifier. The material is fully considered for noise reduction, allowing it to provide greater purification at the same noise level.
In terms of filter configuration, the outermost part is the dust filter, which can be disassembled, which is very convenient when cleaning. Open the back cover of the fuselage, we can see that the high-efficiency composite filter for removing formaldehyde is supplied by 3M and Toray. The filter element is about 305mmX305mmX370mm and weighs 3.4kg.
In order to achieve ultra-high filtration efficiency, the filter element of the breathable air purifier should have three layers in total for each use requirement. The first layer is a 60-mesh PET filter, which can effectively block particles and hair with a diameter of 60 mesh (0.3) or more. Pet dander and dust; second layer H13 high efficiency HEPA filter, which can effectively filter PM2.5, pollen, allergens, bacteria, viruses, second-hand smoke, etc., and single filter efficiency for particles larger than 0.3 microns in diameter It reaches more than 99.97%; the third layer is activated carbon filter, the activated carbon content of the particles reaches 1.1 kg, effectively removes harmful gases such as formaldehyde and toluene, volatile organic compounds and various odors. This composite filter element basically takes care of your family's use. Situation.
On the whole, the smooth breathing purifier uses solid materials and meticulous workmanship. So what is the actual use effect? In the evaluation room with an initial environment of PM2.5 of 17μg/m3 and PM10 of 39μg/m3, we closed the room door and window and then ignited a large number of cigarettes indoors, so that the indoor PM2.5/PM10 concentration increased rapidly. , simulating a bad indoor air environment.
After turning on the purifier, we can see the process of the front display quickly changing from green to orange and then red. The air purifier was manually adjusted to the extreme speed mode. After 21 minutes, the indoor air changed from the original heavily polluted state to healthy. At this time, the PM2.5 reading was 5 μg/m 3 and the PM 10 was 13 μg/m 3 .
It can be seen that the effect of CARD over 800 is really good. During the test, even in the corner of the room, we can feel the wind volume and working noise. However, compared to its purification efficiency, working noise is definitely within the tolerable range.
Basic parameter test performance is excellent
Speaking of noise, the hammer studied the working mode of many air purifiers and found that although many products have high CADR values, the working noise is hard to bear. This is the applicable area under acceptable noise (ERSANL). )".
In order to make the product run quieter, the breathing is DC. Compared with some other purifiers, it not only highlights the noise reduction effect, but also has excellent performance in reducing energy consumption.
At the same time, they have optimized the noise control on the structural design and material selection, adding a mute material to the fuselage to ensure a quiet operation while providing a powerful purification capability.
After testing, under the premise of environmental noise of 32dB, the measured noise of the breathing air purifier under sleep is 34.4dB, and the measured noise in the extreme speed mode is 67.5dB, which is already very good compared with its 800+CADR value.
In the low noise, it also guarantees ample air volume. In the extreme speed mode, the maximum wind speed of the air outlet is 4.11m/s. More humane, in the sleep mode, although the purifier is still working, you can hardly feel it. its existence.
Through actual combat testing, we found that all aspects of the breathing air purifier are above the standard, basically can meet the various usage scenarios in the home, compared to the price of 3499, can be said to be value for money. According to incomplete statistics, there are currently more than 500 air purifier brands on sale, but many consumers still don't know what to choose when purchasing air purifiers. If your home is large enough, this breathing air purifier can give you a pretty good experience.
