When I recall the happy time of my childhood, the sky is blue and the wind is light, and the air is always mixed with the fresh taste of soil and flowers. Now living in Shijiazhuang, where the haze is serious, it has become a luxury yearning to breathe fresh air every day. When the winter heating season comes, the annoying PM2.5 will arrive as scheduled, and sometimes it will cover the color of the sky. Although the state's control over environmental protection has continued to increase in the past two years, air quality has indeed improved to some extent. But there is still a long way to go to get rid of the haze. Therefore, in order to protect the breathing health of the whole family, a reliable air purifier is very necessary.  

Initial JOSE TRONCO  

With the increasing attention of consumers to respiratory health, air purification products have become hot, and many "laymen" from other industries have also been attracted to take a share. Not long ago, Lao Luo, who was "not working hard", unexpectedly brought an air purifier made with feelings at the hammer new product release conference. Surprisingly, it is not called the hammer air purifier, but a very foreign Spanish name "JOSE TRONCO". The brand logo of Wukesong looks fresh and beautiful. But the Chinese name of "Chang Breath" doesn't sound so good to me, just a little bit like "feel" in the urban-rural fringe.  

Regardless of whether the name "Chang Breath" sounds good or not, the CADR value of 800+is really impressive, which is also the first point that attracted me. CADR value is an important indicator of air purifier, which is related to the overall purification efficiency. Naturally, the higher the value, the better. I have experienced almost ten air purifiers, and few of them have a CADR of more than 500. On the market, CADR can reach 800 other products. You can also search on the Internet. Most well-known brands will break the price of 6000, 7000 or even higher. The official price of the JOSE TRONCO breathing air purifier is 3499 yuan.  

Of course, judging the advantages and disadvantages of an air purifier is not limited to the CADR value. Such as: air duct design, motor specification, noise level, human-computer interaction, filter element structure, which are also the key points to be considered one by one, will reflect our final use quality. The difference between air purifiers with hundreds of yuan and thousands of yuan is also the distance between these projects and details. If the air purifier can make the air "shush clean" as Lao Luo said at the press conference, let's take a look at its actual performance.  

"Simple figure and extraordinary temperament"  

Big, really big! The smooth breathing air purifier belongs to that kind of large air purifier, and this image is consistent with its 800+CADR value. The height is 81.7cm, and the weight is 17kg. Fortunately, there is a roller for moving at the bottom, which can be easily moved indoors. However, such a large size figure is still too conspicuous for my two bedroom room with an area of 95 square meters, which will occupy some valuable space at home. I think breathing freely is more suitable for friends with more comfortable living space. If it can slim down again, it may be more suitable for small and medium-sized houses. I hope that there will be a small version in the future.  

The hammer's industrial design skills are obvious to all. Although the air purifier is a relatively functional household appliance product, the overall impression of breathing air purifier is simple and elegant. The whole body is designed as a columnar cube, and the edges are transited in an arc shape, so that the whole body presents a soft and beautiful visual impression, which can be well integrated into different home decoration styles.  

In terms of workmanship and materials, the hammer has always been of a high standard, and the details are handled in a good way. Even a simple power cord is designed with a sense of quality.  

The four pulleys at the bottom are also very particular, and are stored in circular grooves. In this way, it is difficult to find the existence of the pulley outside, which will not affect the overall beauty of the purifier. When it is necessary to move the position, the pulley moves smoothly and quietly.    

"Simple function layout"

There is no fancy design in the functional layout, and it is very simple to use. Function keys and indicator lights are hidden at the top edge without any conflict. One key and one mode key can complete all operations.  

Although it seems that the air purifier for breathing freely is very mechanical, its essence is a highly intelligent product. In addition to operating through the body buttons, you can also use the special APP for smooth breathing, and can manually adjust the air volume in six gears. APP can view the real-time indoor and outdoor air quality, and can query the air quality forecast in the next few days.  

In terms of air quality detection, Changqi is equipped with a laser PM2.5 sensor, whose precision is significantly better than the infrared sensor equipped with some air purifiers on the market. The sensor is located on the upper side of the back of the machine, which has less interference and can evaluate the air quality more objectively. However, Changxing is not equipped with TVOC, formaldehyde and other volatile organic compounds detection modules. From the functional point of view, it is more suitable for use in haze areas.  

The round LCD on the front of the fuselage is particularly conspicuous, because it is not the traditional black, but the same white as the fuselage. With a very high aesthetic degree, it must be another masterpiece of Lao Luo's "obsessive-compulsive disorder". The screen display effect after opening is also very good. Different air quality levels are distinguished by red, orange, green and three colors.  

When When the PM2.5 value is lower than 75, the screen will be displayed in green, representing good air quality. When the value is between 75 and 150, it indicates light and moderate pollution, and the screen is orange. When PM2.5 is greater than 150, it means that the air is polluted seriously, and the screen will also turn to striking red. The brightness of the screen will change with the intensity of light humanized, and there will be no dazzling light pollution in the dark night.      

"Air purification"  

Although the working principle of the air purifier is relatively simple, there is a lot of internal knowledge. Reasonable filter screen structure and efficient air duct design are essential. Thanks to the smooth breathing and tall figure, it can meet the requirements of tower air duct layout, and the airflow circulates from bottom to top. The downward wind energy can effectively capture the dust floating on the ground, and the filtered clean air will be ejected from the four way air outlet on the top, fully driving the indoor air to circulate efficiently.  

The filter structure is composed of a dust filter screen and a hollow cube shaped composite filter element, which can be seen by opening the back plate of the machine body. The outer filter screen can block some relatively large particles, such as hair, dander, floating objects, etc.  

The huge composite filter element is made of raw materials provided by 3M and Toray, and is divided into two layers. The white part of the outer layer is the H13 HEPA filter screen, which can capture the PM2.5, smoke, dust and other small suspended particles above 0.3 μ m in the air. The black part of the inner layer is modified activated carbon, which can remove formaldehyde, toluene and other volatile organic compounds and various odors.

complex The particle CCM (cumulative purification amount) value of the filter element is 50000+mg, which is almost four times higher than the national standard P4 standard; The CCM value of formaldehyde is 4000+mg, which is almost two and a half times higher than the national standard F4. The larger adsorption capacity also determines the long service life of the Changxing filter element. The official recommendation is that the replacement time is one and a half years, which is considered as a relatively long-lived filter element at present. However, the filter element price of 799 yuan is a little expensive in my opinion.  

The air inlet below the smooth breathing air purifier adopts a three sided air inlet structure, while the filter element is four sided. This design may be designed to make the front look more finished and beautiful, but it also wastes a certain filter capacity. The use of four side air intake will not be worse than it is now, and the filtering efficiency should also be slightly improved.  

There is also a slot reserved above the fuselage for the formaldehyde removal super activated carbon filter element. The filter element here is not standard. If necessary, it will cost 699 yuan to purchase additionally. After installation, it can have a more prominent filtering effect on volatile organic compounds such as formaldehyde, which is more suitable for use in newly decorated environments. The operation mechanism works with the help of PM2.5 detection results, because the standard filter element has certain formaldehyde filtering ability, it is believed that most consumers will not add another filter element. It is better to make the air purifier smaller, which may have better effect.

Up to 800+CADR value cannot be separated from a strong heart. The DC brushless fan used is still very powerful. With the backward centrifugal fan, the air volume of 205 CADR can be obtained even in the minimum air volume sleep mode. Then you may ask me whether the noise is big, and I will tell you that it will be big under the strong wind. But under the same noise conditions, the smooth breathing air purifier has a stronger filtering efficiency. For example, cars have four wheels, but the driving experience is different. Audi and Alto are essentially different. Alto may have been torn to death when it reached 120Km/h at high speed, while Audi may have just started to exert its power at this time. There will be great differences between the two in terms of power and comfort, and the difference in the sound of air purifier is the same.  

Actual environment test  

A powerful fan can bring about effective air circulation, but it is also a double-edged sword, which may cause unpleasant noise problems. Now let's do a small test to see the noise and power consumption level of the smooth breathing air purifier under six different air volumes in the actual environment. A mobile phone APP is used to test the noise, and a power meter is used to test the power consumption.

The ambient background noise is 27, and the power consumption in standby mode is only 1.6W.

The first gear air volume power is 7.5W, and the noise is 32.4dB. Almost no sound can be heard, even if you rest at night, you will not be disturbed.

The second gear air volume power is 12.1W, and the noise is 35.6dB, which is equivalent to the low-grade sound of the electric fan.

The wind power of the third gear is 20.6W, and the noise is 40.7dB, which is equivalent to the mid-range sound of the electric fan.

The fourth gear air volume and power is 41.8W, and the noise is 52.8dB, which is equivalent to the high-end sound of the electric fan. It will have some impact on watching TV.

The fifth gear air volume power is 84.8W, and the noise is 60.1dB, which is equivalent to the noise of the range hood.

The sixth gear air volume power is 102.8W, and the noise is 65.8dB higher than that of the range hood. It sounds annoying, and you can clearly feel the air flowing.  

If the automatic operation mode is selected, the fan will rarely run at full load, and most will run in the first two gears. At this time, the overall feeling is relatively comfortable, and will not interfere with daily life.

After two years of vigorous pollution control, the air quality has been significantly improved. Since winter, Shijiazhuang has not seen the weather of haze over explosion. However, in the national air quality ranking, it still did not jump out of the bottom 10. The outdoor PM2.5 value has been around 200 these days, so there is no chance to make the smooth breathing air purifier fully exert its power. But if there is no condition to create conditions, we should also go on~! So combined with the simple air monitoring equipment in hand, we set up a bathroom at home.  

The test method is relatively simple. Close the doors and windows in a 7-square bathroom, light a cigarette (I am a non smoker who showed up for the test) and open the air purifier when it burns out to test the actual filtering effect. The air monitoring equipment in hand is a phantom air box, which can test the PM2.5 value in the environment and compare with the detection value of the smooth breathing air purifier. There are also formaldehyde testers, but I gave up the test when the formaldehyde value at home was very low.  

"Duplicants" went into the bathroom, closed the doors and windows, and immediately began the test. First, open the breathing air purifier until the detected ambient background PM2.5 value becomes 0, and then close the breathing air purifier for cigarette lighting.  

After the smoke goes out, how about the effect of the artificial haze? Take the phantom air box and test it, OMG~！ It is already 999 high concentration haze! It turns out that second-hand smoke is so terrible. Hurry to open the Changqi air purifier to help me eliminate the haze, and see if it can make the air "swish clean".  

Let's record that the startup time for breathing is about 8:13, and the PM2.5 value on the screen reaches a high of 999, when the fan starts to operate at full speed with a roar.  

Within three minutes, after the fan shifted several gears, PM2.5 also rapidly dropped to the excellent level of 22, and the fan began to operate in a quiet low gear. But at this time, the smell of smoke is quite obvious.  

Three minutes later, the smell of smoke in the bathroom was much smaller, but still vaguely existed. The PM2.5 value displayed by smooth breathing reached 4, and the PM2.5 value of the phantom air box reached 9. The air was in a very ideal state. Through this simple test, it can be seen that smooth breathing is very efficient for PM2.5 filtration and has excellent filtration effect. However, since there is no sense and chemical organic matter sensor, the sense generated after smoking will not be purified by high-speed wind shield, and it will take a long time to achieve the effect of purifying the taste. If quick odor cleaning is required, only manually adjust the air volume for intervention.      

Experience Summary

From the appearance, I like the simple and fashionable appearance of JOSE TRONCO breathing air purifier. It doesn't seem to dominate at home. You can work quietly in the corner, which is very consistent with the positioning of white goods. The functional layout is also very simple, with a very good human-computer interaction experience. But the tall figure will still occupy a large space for display.  

From the performance point of view, smooth breathing is very prominent for the purification effect of PM2.5, and it is relatively quiet in operation. In my opinion, although the price of the filter element is still a little expensive, its service life is relatively long, and the use cost is equivalent to that of mainstream air purifiers. The smooth breathing basic version has the function of removing formaldehyde, and also has a formaldehyde removal super filter element that can specifically remove formaldehyde. It can be said that the effect of expanding the filter element in heavily polluted areas is better.  

In general, the air purifier for smooth breathing is a very sincere product of strength. Although it is more suitable for areas with severe smog, it can also effectively remove a variety of hidden pollutants in ordinary households. With the advantages of outstanding materials and excellent quality, combined with a little Laoluo's feelings, the price of 3499 is worth it, which can comprehensively protect the respiratory health of the whole family.
