With the coming tide of urbanization and industrialization, more and more people are concentrated in large and medium-sized cities. With the increase of city size, motor vehicles also increase. In addition, green vegetation decreases after winter, most northern cities face severe air conditions after winter. Although the air quality has improved to a certain extent in recent two years, many consumers still choose to purchase an air purifier to improve the air in their homes for their own health. Therefore, in just a few years, the air purifier has become one of the necessary small household appliances. Today, we will take you to see the KJ400G-E33 air purifier that looks like Zimei.
Appearance and purification experience
Although the biggest role of the air purifier is to purify the air, make our living environment more healthy and reduce the risk of respiratory diseases, as a household appliance that has been placed in the living room or bedroom for a long time, its appearance is very important. As a consumer market product of Midea, KJ400G-E33 has a very simple appearance design, The slender straight tube design of the cuboid makes its circumference only 29 * 29 * 81cm, which can be easily placed on the edge or gap of various furniture.
In terms of body structure, Midea KJ400G-E33 is mainly composed of a base, a body and a control panel. The base is mainly responsible for maintaining the level of the body to reduce the vibration and noise of the motor during operation. The body is where the main mechanical structure and filter screen are located, and the top panel is where the function buttons are located.
The display screen and speed indicator light are on the front of the fuselage. Compared with the H32 we have evaluated before, the design of this model is relatively simple. The white light display screen equipped with this model is most important for displaying the current PM2.5 index, which is also the most important index for an air purifier. Although this kind of design is relatively less scientific, simplicity creates another kind of beauty. Do you think this white light display screen is a little bit fresh.
The filter structure of the machine is relatively common. The bottom of both sides of the machine body is the air inlet, and the air enters the machine body through the mesh baffle on both sides. With the guide plate filtered through the filter screen, the air is discharged from the air outlet on the top of the machine body, and the fresh and clean air is regenerated.
Open the buckle at the bottom of the left panel of the fuselage to replace the filter element. KJ400G-E33 adopts a multi-layer composite filter screen with ring design. The filter element adopts a weighted design. There are five layers of composite filter materials, namely, primary filter layer PET filter layer, coconut shell microporous activated carbon layer, imported H11 HEPA filter layer and PET double filter layer can filter particles of different sizes from large to small, and can effectively remove inhalable particles, bacteria, organic pollutants, etc. in the air.
Among them, the core filter material is HEPA filter layer from 3M/Toray brand, and the long-term electrostatic electret process is adopted, which integrates filtration and adsorption, and can effectively remove particles above PM0.3, which is also one of the most important indicators affecting our daily use. Every winter in northern cities, air quality will inevitably decline due to the decrease of air pressure due to the change of monsoon and the reduction of green vegetation, which will reduce the ability to deal with harmful gases.
In December, most areas began heating, and the solid particle emissions generated by coal increased, which made the air quality worse. In this part of pollutants, particles with a diameter of less than 2.5 microns can be inhaled by the human body, causing great harm to health, which is also an important reason why we should pay attention to the filtration capacity of PM2.5.
In addition to solid particles, it can also filter organic pollutants in the air. The so-called total organic pollutants not only include the common organic substances in our lives, but also include various aldehydes, ethers and other pollutants emitted from furniture. For users who newly decorate or purchase new furniture, this kind of invisible killer is the most lethal.
Midea, which has many years of experience in the production of air purifiers, obviously will not let go of such details. Its filter element has made targeted measures for PM2.5, total organic pollutants and bacteria, which is also the reason why KJ400G-E33 is equipped with a five layer filter element. In terms of parameters, the composite filter element KJ400G-E33 has a PM2.5 CADR of 405m ³/h, a formaldehyde CADR of 280m ³/h, a gaseous organic compound CADR of 260m ³/h, and a toluene CADR of 280m ³/h. Such filter element parameters are quite sufficient for ordinary family living rooms or bedrooms.
In order to test the filtering effect of KJ400G-E33, we used cigarettes to simulate the effect of pm2.5. The original PM2.5 in my test environment was about 30. After a cigarette was burned out, the indoor PM2.5 had broken through 300. At this time, Midea's high speed gear was turned on. In a few minutes, the indoor PM2.5 recovered from more than 300 to about 30, and the filtering effect was quite reassuring.
In general, although the appearance of KJ400G-E33 is not very brilliant, its simple appearance design+large size slightly hazy display screen adds a bit of new meaning to the relatively monotonous body, which is absolutely above the passing grade. It has no problem with the integration of most homes and is very versatile. As a competitive player, the KJ400G-E33 is obviously not comparable to those products that are strong in the outside but weak in the inside. Its filter element with a conscience of material gives it a lot of points. A full 1.2KG filter element gives you a very practical feeling when you hold it in your hand.
Use experience and APP experience
First of all, let's talk about the experience of the body itself. The functions of the KJ400G-E33 are relatively simple, so the operation logic is also very straightforward. All the operation keys are located on the top of the body. Power, speed, negative ions, automatic mode, sleep. A few simple touch keys are all of the KJ400G-E33. After starting up, just touch it gently to start the corresponding functions.
In the daily trial, the automatic mode can solve most problems. It can choose its own speed according to whether the air quality is good or not, so as to purify the indoor air under the most reasonable operating state. In addition to the automatic mode, it is not necessary to mention the sleep mode. In addition to the well-known feature of silence, Midea also added a photosensitive sensor on the operating panel. The purifier will automatically switch to the sleep mode when it senses that the ambient light is darkening. It is quite humanistic, and every bit of it can show meticulous consideration.
Ambient noise -- maximum speed noise -- minimum speed noise
In addition to the air filtration capacity, noise is also a key factor affecting the user experience. Therefore, we conducted a special test on the noise of KJ400G-E33. First of all, we tested the ambient background noise. The ambient decibel is about 40 decibels in a quiet state. We tested the minimum speed and maximum speed in decibels. At the minimum speed, the noise only hit 43 decibels, which is still quite quiet. At the maximum speed, the noise only reaches about 60 decibels. Although the noise from the purifier can be clearly perceived, it is still in a relatively reasonable range of control.
Of course, with the tide of intelligent hardware sweeping all aspects of life, air purifier is also one of them. Midea has developed its own smart home platform, which includes almost all of Midea's products, from traditional appliances such as air conditioners and refrigerators to small appliances such as fans and air purification. Today's KJ400G-E33 we experience is one of them.
After matching the air purifier with Meiju APP, Meiju can be used to control the air purifier. All operations that can be completed on the body can be operated on the APP, which is very convenient. For example, if you want to get clean indoor air when you go to work, you can open the purifier in advance through the mobile phone APP, The moment you go home and open the door, you can welcome a fresh and good mood.
summary
As Midea has many years of experience in the production of small household appliances, the air purifier is obviously a handy product. The KJ400G-E33 we tested this time has also demonstrated enough skill. Although it is small, it has no compromise in terms of purification performance. It can achieve a purification rate of 91% in 10 minutes and 99% in 20 minutes within an area of 30 ㎡, which is quite outstanding. In addition, Midea adopts scientific standards, not only pm2.5 standards, but also TVOC monitoring, and comprehensively and scientifically purifies air quality. Midea is a small expert in comprehensive air purification.
As a product of Midea competing for the mainstream consumer market, Midea air purifier KJ400G-E33 focuses on the small and medium-sized family market, and is suitable for the space of 28-48 square meters, such as the family living room or bedroom. Its slim shape allows it to be easily placed in various corners, minimizing the occupation of space, which is valuable for first-line cities with a lot of land. On the whole, as a household purifier, Midea KJ400G-E33 not only has strong purification capacity, but also has a good appearance and ease of use. After starting the automatic cruise mode, it can be used once and for all. It can be said that among the products of the same grade, Midea KJ400G-E33 has strong market competitiveness.
