This time, we played with Amway, and it was a new fan, the AirmX Pro 1S, which was used as a supporting unit for IKEA's model room. It is said that "if I have money, I will buy it", "if it is expensive, it is worth it", "I regret not having bought the series earlier", and "I cannot go back after using it".
What is the fresh air system?
The safe concentration of PM2.5 given by WHO is 10 (10 μ g/m three ）Among the top 100 cities in the world, the PM2.5 of the last one is 4. As a comparison, Beijing PM2.5 has a daily average of about 100, and Shenzhen PM2.5 has a daily average of 20-30. The moon in foreign countries will not be particularly round, but the air in big cities in China is certainly not good.
What if the air is bad? Everyone's first reaction is the air purifier, but actually there is a scheme called fresh air system above the purifier. The penetration rate of fresh air fans in European and American countries is close to 100%, but it is less than 2% in China, where the air quality is worse. According to the rhythm of intelligent toilet lid and dishwasher, the popularization of fresh air system will be a big chance.
What's wrong with the purifier? Its core life gate is that the space is closed, and hypoxia easily leads to "clean but not fresh air". In addition, formaldehyde and other indoor pollution gases that cannot be handled by the filter element will be more likely to exceed the standard of formaldehyde if the purifier is used to close doors and windows.
The idea of fresh air system has a feeling of "this should be". The core of fresh air is air exchange. By filtering the outdoor air and delivering it to the room, the original indoor air is squeezed out of the room to keep the indoor air clean at all times.
Such a scheme has many benefits. The ventilation problem is solved. The external circulation is not a closed system and is not afraid of hypoxia and carbon dioxide accumulation. Since then, there is no need to open windows regularly and be afraid of dust. It also "solved" the problem of accumulation of formaldehyde and other volatiles. The pet smell and decoration odor that cannot be removed by the purifier can also be solved.
There is a saying that the whole room fresh air system is the ultimate solution for indoor air and dust problems. Once the tail is broken, there is no need to deal with the air problem later.
appearance
The AIRMX Pro 1S is obviously a totally white and simple Nordic style, with elegantly and restrained design. The top surface of the fuselage is basically full of air outlets. After careful calculation, there are 792 small openings in total.
AIRMX Pro 1S is 45 * 39 * 129 cm in three dimensions, covering an area of 0.17 ㎡, and 59kg in bare metal. This specification is almost the same as that of a small refrigerator, but the appearance is very light. No matter what the decoration style of the home is, no matter where it is placed, it is not abrupt.
The machine adopts centralized button, switch, AI mode, air volume control, electric heating, and all interactions are clear at a glance. Even the button light is also "invisible" design, which will light up only when sensing the human body.
Another special point in industrial design is that it comes with a split Bluetooth detector. This is probably one of the most beautiful detectors in history. Aluminum alloy body, large touch screen (finer than the dwarf screen of iPhone SE), even with its own light sensor.
The system operates smoothly and various customized projects seem to be running Android, which is really cost free. In addition, it uses Bluetooth. For pregnant women, infants and other users who need to worry about the high WiFi radiation, this should be very palatable.
Terrible filter element and cracked motor
Turn on the machine, and the hardest and most violent part comes. As strong as AIRMX Pro 1S, you will find that even IQAir, the king of air purifiers, is too conventional. AIRMX Pro 1S adopts triple tower filter design, and the air duct passes through G4 primary filter element, modified activated carbon and noble HEPA13 glass fiber filter element from bottom to top.
In the field of fresh air and air purification where top filter elements and motors are extremely "thick", size and weight are top symbols. On AIRMX Pro 1S, these three layers of filter elements alone add up to nearly 5.5 kg, which is burning funds.
Three layer filter element
This G4 primary filter cotton with a surface area of 0.7 square meters has very high dust capacity but very low wind resistance compared with common primary filter paper. The official said that even in Beijing, the air volume of 300 cubic meters per hour can be kept working for half a year.
The modified activated carbon filter element adds 800g of activated carbon to the honeycomb like grid. Compared with common activated carbon, the main improvement is that the specific surface area is higher, which improves the adsorption capacity of formaldehyde, tVOC and other harmful gases and small particles. The CCM level of formaldehyde has reached F4, which can deal with the odor that cannot be handled by common filter elements such as toilet ammonia, decoration toluene, outdoor soot, and automobile exhaust.
Close up of three filter elements
The core is the military HEPA13 glass fiber filter element. It can be said that many of the changes in the industrial design of AIRMX Pro 1S began with the decision to use this most powerful filter element. The outer layer of HEPA13 glass fiber filter element is protected by a metal mesh, which is very thick and heavy, and the woven aperture is as small as 0.1 μ m, so it has a strong ability to capture particles. It was first used in the Manhattan Project (the first atomic bomb in mankind) to isolate radioactive particles, and then used in the operating room and chip manufacturing and other occasions that need ultra-high sterile environment. This most powerful filter element in history has a filtration efficiency of more than 99.97% for PM2.5.
For the filter element, each parameter is so perfect: large capacity, long life, and never decay. Even in Beijing level air conditions, it can work 17000 hours (about 708 days) for a 100 square meter house. It is higher than the "low-grade filter+electrostatic" HEPA13 filter elements that decay quickly and have pollutants falling off.
In order to deal with the HEPA13 glass fiber filter element that can not be blown through by the normal fan, the AIRMX Pro 1S is equipped with a burst motor. How awesome is this motor? Germany ebm is the only fan supplier in the world that can handle HEPA13 glass fiber filter element. The fans of ebm are divided into three series: AC, DC and EC according to low, medium and high.
We often hear about IQAir, the king of air purifiers, which only uses DC series motors at the middle end of Germany's ebm, while AIRMX Pro 1S is equipped with top class EC series energy-saving external rotor brushless backward centrifugal fans, whose air volume per hour can reach more than 1300 cubic meters, which is a number several times higher than the common specifications
Purification effect experience
Although we know that the filtering effect of AIRMX Pro 1S is very powerful, we only know how exaggerated it is when we see it with our own eyes. In normal cigarette test, there is only one cigarette, and the pressure is too light. We directly add five cigarettes and connect them near the air inlet. The detector is linked with AIRMX Pro 1S for AI automatic operation.
40cm away from the air outlet, the smoke seems to be sucked into the range hood from afar. Cigarettes can make PM2.5 outside explode at once, and the tVOC can reach more than 2.4.
However, AIRMX Pro 1S seems to have no cigarette in mind, the wind speed has not changed, PM2.5 at the air outlet has no impact, it is still below 10, and TVOC has directly "halved" to 1.25.
We directly served the smoke cake. The amount of smoke was really frightening, but the air suction speed of AIRMX Pro 1S was even more exaggerated. Before the test, I was worried that the smoke alarm would be triggered, but the experiment proved that I was completely over worried. After the high air volume is triggered, the distance is also 40cm, and the smoke will become a "horizontal line" when it floats 10cm outside the air outlet. The large air volume can really do what you want.
Although the smoke cake formation is very scary, it also triggered the machine to adopt a larger air volume, resulting in the PM2.5 and tVOC readings of the detector being inferior to cigarettes (the smoke has no time to stay). Even so, it has increased carbon dioxide concentration 10 times.
On the air outlet side, after the air volume increases, PM2.5 is also pressed around 10, and tVOC is also pressed to the normal level, even lower than that during cigarette testing. However, the high carbon dioxide air polluted by the smoke cake cannot be reduced by any filter element. But because of the principle of the fresh air system, it can suck in fresh air and directly reduce the concentration of carbon dioxide, which is something the air purifier can't do in a lifetime.
Even if it is a cigarette cake, the test pressure seems too light. But when you think about it, this is a new air blower that can handle 200 square meters of space. The air volume is large enough to breathe 72 times a day for the house. No wonder the official dare to promise to refund and compensate when PM2.5 is higher than 10 (2000 when PM2.5 is higher than 10 in every room of the whole house when PM2.5 is lower than 150 square meters).
In fact, after AIRMX Pro 1S filtration, the indoor air has never been so fresh, clean and transparent, and the window opening can not achieve this effect. And our test site is still in the house near the street in the downtown area. The air here can also cause extreme comfort and emotion.
Active noise reduction of High level
The child's math score is not good. You work as a manager in the bank to maintain customer relations. There are house loans and car loans, with a monthly mortgage of 5000 yuan. Your wife works in the company. She doesn't love you. When you were young, you thought you could become a career, but now it is the same. Friends are better than you. Hang up the customer's phone and beep, the world suddenly quiets down. It's too quiet. There are few quiet moments in your life. You plan to stay for ten minutes before eating chicken. The above is the evaluation of AIRMX Pro 1S noise reduction effect.
Like the purifier, the fresh air system must be equipped with a powerful motor when equipped with a powerful filter element. The motor is stronger, and the sound insulation and mute should also keep up. The sound insulation cotton is put on the ground layer by layer, and the high frequency noise is suppressed by stacking materials. After opening the "refrigerator door" of AIRMX Pro 1S, you can see that there are thick sound insulation foam inside the door panel and filter element. Officially, these are the best sound absorption sponges used in nuclear submarines and high-speed railways. In the test of Germany's EBM acoustic laboratory, the minimum noise is only 22 decibels.
To further develop, it is necessary to solve the problem of low-frequency sound with strong penetration ability. Then Mixin unexpectedly used active noise reduction on the new fan... The principle of active noise reduction is to use the sound of the opposite wave band to offset the noise. The AIRMX Pro 1S uses a six microphone array. After the AI computing unit processes the noise information, it uses two sets of Hi Fi speakers to emit the reverse sound wave equal to the noise.
Helicopters and Cadillacs have also used similar technologies to deal with low-frequency noise, and the AIRMX Pro 1S should be the first new fan on the earth to actively reduce noise, or even the first in the field of household appliances. However, in the open environment, 3D noise reduction is not a bit more difficult than that of earphones. In addition to the response time being controlled at 0.00029 seconds, the noise has also become a spherical wave, which is difficult to predict. What will the actual effect be?
The test ambient noise is about 43.6 decibels, which is the noise level of most households. The silence mode of AIRMX Pro 1S is about 45 decibels. I can't feel it working without listening closely to my ears.
When the power is fully turned on, the noise is 53 decibels, which is lower than that of many small empty machines. The passive sound insulation effect of the machine is quite obvious. When the noise reduction mode is turned on again, it can reduce 5.4 dB. When the acoustic unit is 3 decibels, the sound power will be doubled. The difference of 5.4 decibels is very obvious.
How do you describe the feeling of noise reduction? It seems that some switch was suddenly turned off, which is a bit unreal and unbelievable. Just like the unreal perception error when touching unconventional materials such as diatomite, ceramics and magnesium aluminum alloy for the first time. Oh, yes, the same is true for the first time when listening to the awesome noise reduction earphones. In normal use, I can hardly hear the fresh air blower running. I'm not joking. It's really quiet.
Non influence intelligence
On AIRMX Pro 1S, there are all designs that try to be "insensitive". You may not think of a new air blower. Why are there NFC, Bluetooth, light sensor and distance sensor? The light sensor is used to automatically control the brightness of the indicator light at night. The distance sensor will automatically light the button and indicator light when people are close to it. The filter element with NFC can sense whether it has been replaced, has its own life record, does not need to be reset manually, and is not afraid to buy fake products. Even electric auxiliary heating can be automatically started and stopped according to the inlet air temperature.
Oh, by the way, the distinguished German ebm EC series centrifugal fan also "comes with" the function of stepless speed change, which can be adjusted freely in the app.
Its AI mode uses various air sensors to sense the air index and internal and external pressure difference, automatically calculates the optimal ventilation volume according to the outdoor environment, user room area and floor, and always maintains a slight positive pressure. It does not fix the air volume like ordinary fresh air. It is always resistant to the outside dirty air, which greatly extends the service life of the filter element and controls energy consumption and noise.
Seriously, this kind of interaction design is worthy of being called non sense.
summary
AIRMX Pro 1S has non electrostatic electret HEPA13 filter element, original EC fan imported from Germany, 100% air intake area and ventilation pipe, split detection, medical grade differential pressure sensor, electric auxiliary heating, NFC filter element, and active noise reduction, only 16999. Yes, you heard me right, only 16999. At first glance, this price may exceed many people's psychological expectations.
But its purification effect is four IQAirs (18700 × 4=74800), and one 200 square villa is also available. The price of 16999 suddenly seems a little fragrant. The distinguished German ebm EC series brushless centrifugal fan saves a lot of power, and rounding off the electricity cost equals no money. However, a set of 1100 filter elements, which are replaced every two years, have lower use costs than hundreds of pieces of air cleaner on average.
For users whose children have just been born, who have just been decorated or are about to be decorated, or who live on the roadside or in the city center, this may be the equipment that you regret not buying earlier. Why don't you think about it in one step? If you find something wrong, you will make progress immediately. There is not so much waiting in life.
