The temperature in early winter is not very low, but the oncoming wind still makes people tremble. In order to prevent colds, the office doors and windows are closed and the air conditioning warm air is turned on early. However, the air is not circulating, the smell is bad, and Nanjing is humid and mellow.
Falling in love with a city full of haze, the body can't stand tossing.
Thinking that this is not enough, air quality has a great impact on health, so I put the matter of buying an air purifier on the agenda. At the domestic Mate 20 series mobile phone conference, Huawei released a Huawei intelligent ecological product 720 full-effect air purifier, which integrates four purification technologies: haze removal, aldehyde removal, sterilization and freshness.
We made a multi-product comparison chart. As long as the price of this configuration is 1299, it can't be played. It's beautiful! I confirmed my eyes. That's him.

After two days of tenacious struggle in the smog, this air purifier finally arrived late and quickly unpacked. The entire outer packaging is mainly white, and Huawei intelligently chooses four red characters, highlighting that this is an ecological product compatible with Huawei smart home.
Open the box, the air purifier is covered with a canvas bag, which is convenient for users to take out the purifier, and it can also provide dust protection for the machine when it is not in use, and it is no longer afraid that mother will buy an air purifier cover.
After opening the canvas bag, the body of the whole air purifier appears, which conforms to the simple white body of Internet product design, and the rounded design around it not only low-key matches most home decoration styles, but also plays a role in preventing bumps. The circumference of the machine is 325*325*650mm, so this design does not occupy space, and it will not appear abrupt at home or in the office.
Above the front of the machine is the logo of Huawei HiLink, which is also an air quality indicator. It displays the current air quality through three different colors: green, yellow and red. Below the sign is a hidden display screen, which can show the PM2.5 content in the air and the current air volume level.
At the bottom of the front is the brand logo. Maybe you are new to 720 health technology. This is a company concerned about environmental health. In addition to purifiers, there are also products such as detector fresh air systems, which are highly professional in the vertical direction. Otherwise, Huawei Zhixuan will not choose to cooperate with this company.
According to official data, the air intake area of this air purifier exceeds 38,000 square millimeters, which lays the foundation for a larger air output.
On the back of the machine is a detachable back cover for removing the filter element, and a special handle is designed for easy removal.
At the bottom, there is a power socket. The position of this jack is designed to be hidden, which ensures the aesthetics in the actual use scene.
The top of the machine is the air outlet. The grille design ensures a large air outlet area of 465,438+0,000 square millimeters, which not only has the function of mute and noise reduction, but also can prevent children from reaching out or foreign objects from falling in more safely.
There is a status indicator next to the air outlet, which is also a touch button. I have to praise this design. The function display and control are integrated, which makes the control more intuitive, and there are no redundant buttons, which ensures the appearance. It can be said that it is one of the best designs of purifiers on the market at present.
At the bottom of the machine is the nameplate and rubber pad of the machine.
Four oversized foot pads have good shock absorption effect, reducing noise and vibration when the machine is running.
Open the movable backboard on the back, and you can see the inner filter element.
A detachable small cover plate can be seen in the upper part of the filter core bin, which contains a sensor for detecting air quality, that is, the high-precision laser sensor mentioned in the propaganda, which can accurately distinguish particles above 0.3 micron.
At the top of the filter bin is the core component of the purifier, a huge fan driven by a motor.
The bottom of the filter cartridge bin is a movable bottom plate, which is matched with the limiting groove to ensure the filter cartridge to be installed in place, and at the same time, the sealing performance during use is improved, so that the purifier has better effect.
Purifier, start!
The appearance of Huawei's intelligent ecological product 720 full-effect air purifier is a very mainstream design in the market, and it also has its own characteristics in touch and other details. So what is the purification effect? Can it achieve the four purification functions of smog purification, aldehyde removal, sterilization, refreshing and purification? Don't worry, keep looking down.
The CADR value of particulate matter is as high as 500m3/h, and the CADR value of formaldehyde is as high as 200m3/h, which is even better than many top brands of air purifiers on the market in terms of parameters.
Transparent mist
Just two days ago, there was a very serious smog in Nanjing. According to the actual measurement, the content of PM2.5 decreased from 109 to 1 1 after the original 20 square meters were used for10 minutes, which was heavily polluted and almost closed. From the data point of view, the effect of purifying PM2.5 is still very good.
Aldehyde removal & freshness
As for the function of fresh air and in addition to formaldehyde, it is mainly accomplished by activated carbon and negative ions. In official website's introduction, the filter element of Huawei's intelligent ecological product 720 full-effect air purifier adopts imported coconut shell activated carbon, which can effectively adsorb formaldehyde, toluene, cigarettes and odor, and play a role in filtering odor and harmful substances in the air. On the other hand, this air purifier is also equipped with a negative ion generator, which can effectively absorb the odor and floating molecules in the air and achieve effective odor removal. In addition to formaldehyde function.
In order to verify the effect, we moved this purifier into the boss's office, which often smokes and smells like smoke all over the house. The air quality deteriorated instantly and the data began to soar.
So I started the purifier to the highest level to purify the air. After about half an hour, the whole office smelled of smoke. The purifier shows that the air quality has returned to normal level. It seems that there will be a meeting in the boss's office in the future, so don't worry about the smell of smoke after coming out. It can be seen that this function of purifying air is perfect.
disinfect
Sterilization function is rare in purifiers on the market. Spring and autumn are the high incidence periods of various epidemic diseases, which are easy to cause infection in closed rooms. This 720 full-effect purifier adopts 254 nm deep ultraviolet UVC sterilization method, which is also the most widely used sterilization method in disinfection industry at present. The inside of the purifier can effectively purify the air, kill bacteria, and prevent bacteria in the closed space from secondary infection through the air. Although it is not as thorough as ultraviolet lamp, it is better than working all the time, and it is not necessary to sterilize people like ultraviolet lamp.
noise
According to official website, the air volume of this air purifier has reached 500m3/h, and the purification effect with large air volume is better, but the noise will also be a big problem, especially for the elderly and children, or those who want the purifier to work while sleeping. To this end, we also specially tested the noise index of this purifier. The noise control of Huawei's intelligent ecological product 720 full-effect air purifier is satisfactory. After the purifier is adjusted to full load, the noise level measured at the distance of 1m is lower than 50 decibels, which is a little lower than that of ordinary people. If the sleep mode is turned on, the noise will not exceed 20 decibels, which is equivalent to the sound intensity in a quiet night and will not affect sleep at all.
We just moved the knife and started to dismantle it.
So what makes this purifier achieve such an effect? We decided to "find out" and look at the core of the purifier-the filter element part.
Disassemble the filter element first. The filter element of Huawei intelligent ecological product 720 total effect air purifier is quite thick, weighing 1.3kg,
It is heavier in the mainstream air purifier at present.
Brand logo is printed on the top of the filter element, and a sealing ring is designed to ensure better sealing effect.
The measured filter element has a diameter of about 270mm and a height of about 320mm, which is a whole circle larger than the diameter of 200mm and the height of 293mm in the universal version of Xiaomi purifier. A larger filter element represents a better purification effect and a larger air intake, which also means that a filter element can be used for a longer time.
The sealing layer is made of sponge and directly bonded to the filter element, which greatly enhances the sealing performance and can also absorb shock well during operation.
The filter element and the upper and lower plastic parts are assembled together in a fitting way, which is very firm. It takes two people to pry it open and tear it off.
After removing the plastic parts, we can visually see the overall structure of the filter element.
The thickness of the whole filter element is 4 1.74mm, and several filter elements are basically crushed, and each layer has different functions and functions.
The first layer of nylon mesh: used to filter out the big dust in the air, such as hair, fine chips, flocs and so on. And directly integrated on the filter element, which is more convenient for users to clean and replace.
The second filter layer: HEPA filter paper with high grade H 12 is adopted, and the folds *** 164 effectively increase the contact area with air and effectively filter PM2.5 to PM0.3 and suspended particles in the air.
The third layer of nylon mesh: fixed activated carbon.
The fourth and fifth layers of activated carbon are used to adsorb decoration pollutants, such as formaldehyde and TVOC. With the double-layer design, activated carbon is evenly placed on the net structure, which further increases the contact area with air and fully improves the evolutionary efficiency.
The sixth layer of nylon mesh: fixed activated carbon.
The seventh layer of diamond-shaped barbed wire: responsible for supporting the whole filter element.
Generally speaking, the filter element I consists of seven layers. From filtration, adsorption, deodorization and fixation, the design standard of the complete first-class filter element is complete. As an air purifier with a price of only 1299, such a high cost performance really exceeded my expectations.
