preface
I always feel that in recent years, haze has erupted inexplicably! In fact, long ago, while we were developing the economy to catch up with the pace of industrial society, the problem of air pollution has emerged, but we did not know about "haze" The terms "PM2.5" also do not understand the harm of haze, so air purifiers, as new products, have attracted great attention. How effective is it in improving the indoor air environment, and whether the publicized data is reliable? What aspects do you need to pay attention to when purchasing air purifiers?
The author has been paying attention to the air purifier products because of the preparation of the second child at home, and has summarized some tips for you to use for reference. First, choose brands. New products will have some products that make up the number. It is reasonable to recognize the public's choice; Second, the parameters can reflect the product performance to some extent, not to mention the data fraud; The third is to look at the test report. The air purifier products will post the third-party test report on the detail page. If you can't see it clearly, ask the customer service for it; Fourth, you can go to the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) and the General Administration of Quality Supervision, Inspection and Quarantine of all provinces to check the sampling report of relevant products, or you can find the introduction on the purchase of air purifier products in TV programs such as Consumer Proposition.
Unpacking
Just received the express delivery, I was really shocked by the size of this big guy. The packing box was more than one meter high, and the back seat of the car was full of its own. I had to take a rest when I moved to the middle of the third floor alone.
Inside the package is a thick layer of shockproof inflatable bags and up and down cushioning foam plastic. Under the unspoken rule of violent sorting, throwing and flying, the consumers themselves are the victims who do not pay enough attention to the packaging.
The exterior of the product is mainly made of aluminum alloy. No wonder the whole product is so heavy. In terms of color matching, the mainstream silver black tone is adopted, which is easier to match with various decoration styles. As a "white household appliance", the air purifier does not want to be so eye-catching. It is its mission to turn on the power and put it in the corner to silently complete its work.
Appearance details
The appearance design of the Outlanders KJ950F-H9 air purifier completely follows the principle of symmetry, and the appearance of the sides around is almost the same. It is a metal shell with a black air intake grille in the middle, so the whole lower part is surrounded by air inlets.
The top is also a symmetrical geometric division, the middle black is the LCD screen, and the rest is the top air outlet. The bottom air inlet and top air outlet can form efficient air circulation.
Generally speaking, a family will only buy one air purifier, except for local tyrants. They will be placed in the living room during the day and moved to the bedroom at night. The bottom has only four corner rubber foot pads and is not equipped with universal pulleys, which will be very inconvenient to carry.
The power interface is located at the bottom corner. There is a small episode here. During the initial installation, the author did not pay attention to the prompt text above. There was no response after the power was turned on. After searching the machine body and the manual, I did not see any places similar to the power switch. The internal filter elements were originally designed with dust-proof sealing packaging when they left the factory, When the filter element is not installed in place or the machine is overturned, the power supply will be cut off protectively to prevent product damage or personal injury.
What needs to be pointed out is that the installation position of the filter element in the instruction manual is at the bottom of the machine. The author almost didn't remove the bottom plate of the machine. Usually, replacing the filter element would not be too complicated, so a careful inspection found the opening on the back.
Inner structure of filter element
Remove the fixing tape and pull the handle to open the position of the filter element.
The key to air purification is the filter element. Generally, the volume of the filter element determines the purification effect to some extent. The filter element of Outlanders is heavy in the hand, and its volume accounts for almost half of the product.
The thickness is also quite full visually. After all, the filter element is expensive, so the author will not carry out a destructive profile display. The following is an official introduction: the first layer of primary effect layer is composed of antibacterial fiber mesh cloth and sterile non-woven cloth, which intercepts and filters large particles such as dust, hair, dander, etc. The second layer of the sixth generation hapteptide bacteria HEPA can adsorb formaldehyde, benzene, ammonia PM2.5、 Bacteria, viruses, etc., and decompose harmful substances. The third AC efficient activated carbon layer adsorbs volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene, etc.
The bottom of the filter element is a manual fixed chassis, which forms a seal through the chassis and the sealing strips around the filter element, so that all the incoming polluted air passes through the filter element.
The basic principle of the air purifier is that the fan moves the air so that the polluted air is filtered and purified through the filter screen, and then the purified air is discharged and re enters the space circulation, just like the blood in the human body, in which waste is discharged. Therefore, as the "heart" of the air purifier, Outlanders has all adopted fans from F1 racing suppliers, and the specific performance will be shown in the later test session.
user's experience
Although the principle of the air purifier is simple, it is not necessary to find a supplier to provide the filter element, and then find a supplier to provide the fan. A customized housing is enough to be marketed. Think carefully about the principle of refrigerators and washing machines. Isn't it simpler? Therefore, a set of intelligent control and operating system is the most intuitive aspect for users to use.
The main panel of the Outlanders air purifier is rich in information, and the PM2.5 concentration, pollution level, temperature and humidity can be displayed through the internal sensor.
In terms of function, in addition to the purification effect of the filter element, a negative ion device is also added to remove odor by continuously releasing negative ions.
In terms of control, intelligent mode, manual wind speed, timing mode, sleep mode, child lock, etc. are provided for panel and remote control operation.
It is worth mentioning that Outlanders also supports APP remote control. Through simple networking settings, you can perform all operations, including switching on and off, and the power consumption in standby mode is only a few watts. However, when using the newifi route plus hammer M1L, the author needs several attempts to connect successfully. If the router is turned off, it also needs to be connected again. The networking experience is poor. However, as long as the networking is successful, the remote control of various functions is very smooth.
Measured experience
Before the test, first look at the product parameters of Outlanders. First, the most important parameter CDAR value of the air purifier refers to the ratio of clean air output by the air purifier. The higher the CADR value, the higher the purification efficiency of the purifier. The maximum CDAR value of the national standard is only allowed to be marked with 800, while the value of Hollandes is 980, followed by the value of formaldehyde CDAR. Most domestic mainstream high-end brands are around 400, while Hollandes is 610. From the parameter point of view, the price of more than 7000 is good among imported air purifiers.
Noise wind speed
Before the noise test, the ambient sound test was carried out first. The author specially selected a time when the ambient noise was more than ten decibels in the dead of night. The highest value of 24 decibels was the sound of the camera motor. You can refer to it for comparison.
From the sleep gear to the fourth gear of the highest speed, the author tried to avoid the impact of external noise. The reason why the test was not taken on the same screen was that the display screen and the air outlet were on the same top, and the mobile phone would have a very loud wind noise when placed on the air outlet, so it could only be tested when it was away from the air outlet position, while we usually did not use an air purifier nearby, So the noise perception will be lower than the test effect, of course, the test did not use professional instruments and professional environment, for reference only!
Sleep gear: Breeze, noise up to 25 decibels, in fact, only 10 decibels, the sound of the camera motor is unavoidable. In this mode, you can only hear the sound like a clock ticking.
First gear: Breeze, the highest noise is 29 decibels. In fact, there is almost no difference between the listening sense and the sleep gear. That is, the display screen is closed when the sleep gear is turned off.
Second gear: A small amount of wind, the highest noise is 37 decibels. The wind noise at the air outlet can be heard at this wind speed, but it is not obvious.
Third gear: The fan in the normal gear can feel the breeze three meters away. The noise is up to 50 decibels. The wind noise is obvious. At this time, if you watch TV, you will notice the wind noise, but it is not noisy.
Fourth gear: similar to the high-end air volume of the hair dryer, you can feel the obvious air flow three meters away. The noise is up to 60 decibels. The wind noise is large, and the TV sound has some influence.
In the whole test, except for sleep and first gear, the sound of fans and motors is covered by the wind noise at the air outlet, which is unavoidable. Therefore, the noise of high-end products at the same price on the market is almost at this control level.
Purification effect
When it comes to purification effect, it is impossible to avoid the design of air volume and air duct. Under the same conditions, the more air passes through the air purifier in a unit time, the higher the natural purification efficiency. Single side air inlet and small outlet air outlet, even if the purification effect of the filter element is no better than the design of four side air inlet and full roof air outlet, so everyone must pay attention when shopping.
In this link, let's invite the author's collection of cigarettes. The author is a "smoker" who has smoked for ten years. Ha ha, he is very familiar with the harm of tobacco. In addition to producing a large number of particulate matter such as smoke and PM2.5, smoking will also produce harmful substances such as nicotine and tar, followed by the unique smell of tobacco, which can be said to be a necessary artifact to comprehensively test the purification effect.
The test environment is the living room of the author's house. Before the test, close all doors and windows to create a relatively closed space. At first, it was a natural experiment of cigarettes, but I couldn't resist a peck, and the result was that the watch exploded! Because only one puff was taken, the air quality became better more than 30 seconds after the meter exploded. At this time, the cigarette was still spontaneously combusting, because there was less smoke, the value did not rise. Of course, this is only the time to purify particles. The smell of tobacco still exists, but it is not so strong.
It seems that the amount of smoke from spontaneous combustion is not enough to reflect. In addition, the author's addiction to tobacco is disorderly. He lit another cigarette and started the test. He smoked a cigarette in less than two minutes. Ha ha, have you noticed that a good cigarette is a good cigarette, and the ash will not break! The power of two cigarettes, even in the large space of the living room, still has a clear smell of smoke, and PM2.5 has again exploded! It took 75 seconds to purify to excellent this time, wait! Why is the value over 60 again? It turns out that the author used the intelligent mode during the test. From the poor, medium, good and excellent air quality, the wind speed is automatically switched to the fourth, third, second and first gear. After all, it is equipped with the intelligent mode. Who needs to manually switch. So the author boldly speculates that when the wind speed is high, PM2.5 quickly gathers for purification, so the purification speed is very fast in the early stage. When the air quality is excellent, the wind speed drops to first gear, and the indoor air circulation becomes slower, leading to the slow entry of the polluted air in the distance. Then there are repeated values of more than 40 to more than 60, and this repetition gradually decreases like the amplitude, and tends to stabilize in about 30 minutes, and the smoke smell almost disappears in about an hour.
In addition to the purification test of particulate matter, there are no professional quantitative tools for other pollutants in the home environment after all, so the author would like to talk about some experience in using them. Generally speaking, after a night's sleep, the closed bedroom will have more or less the body odor of some people, while in the days I use it, the smell will be very light after getting up in the morning compared with the previous days.
Personal opinion
After a period of experience, in addition to some unfriendly experiences on the wifi connection, the Outlanders KJ950F-H9 air purifier has met the author's expectations in other aspects. Its most prominent feature is its large brand, large volume, large air volume, large parameters, and large application area. If you are a user of a three bedroom large house, you do not want to buy two air purifiers, Think about it.
