The word "haze" has been known by people in recent years. With the worsening of air quality, the number of cities affected by haze weather is increasing year by year. More and more people have been able to feel the harm of haze to their daily life, and it seems to be a luxury to breathe fresh air. The optimization of outdoor environment can not be changed in a short time, which requires a long-term process. However, the appearance of air purifier can let us enjoy a pleasant breath at home. As people pay more attention to environmental issues, the air purifier has grown rapidly in recent years and has begun to enter more and more families. At the hammer press conference a few days ago, Lao Luo (Luo Yonghao) introduced a smooth breathing intelligent air purifier in addition to bringing us a new nut Pro 2, Whether this air purifier can continue the "craftsman spirit" of Hammer Technology, and whether it can really make the indoor air "shua clean", I will take you to find out in detail.

Unpacking:

The package of Changqi intelligent air purifier is very simple. My first impression is that it is big, and then it is heavy. I moved from the first floor to the fourth floor alone. I still had two breaks in the middle before I finished. The front side of the package box is the brand logo and product name that can breathe freely. There is a clasp on both sides, which is not only convenient for users to carry the purifier, but also has other functions.

The way to open the package box of the Changqi air purifier is very interesting. It is slightly different from other air purifiers. The user only needs to cut off the packing belt, and then clasp the clasps on both sides to lift the whole box, and the air purifier can be taken out.

The upper, lower and four sides of the packing box are provided with foam protection, which can effectively prevent the purifier from being damaged during transportation. The instructions for use and power lines are placed at the bottom of the packing box. In fact, compared with the packing box, the air purifier for smooth breathing is much smaller. Didn't you see the parts? The smooth breathing air purifier has been assembled from the factory. After receiving it, the user can say that it can be used with power on. Of course, it should not be directly plugged in for use. It still needs to be handled slightly.

On the top of the purifier is a piece of paper printed with key logo and quick use instructions, which enables users to quickly master the basic use skills even if they do not read the instructions. Moreover, there are many simple use instructions and notes behind the introduction, and it must be said that the hammer official did a good job in these small details.

appearance:

The overall design of the smooth breathing intelligent air purifier is mainly simple and adopts a white cuboid vertical design. Here, we first use a dynamic diagram to give you a general understanding of its body structure. The corners of the machine have been arc treated, so the whole machine looks very beautiful, and it is easy to integrate into various home environments.

The product size of the smooth breathing air purifier is 384mm * 384mm * 819mm, and the net weight is 17kg (including the filter element). The volume is relatively large. As a high-power purifier with 800 CADR, it is incomparable to those small and portable air purifiers.

There is a circular display screen near the middle of the upper part of the front of the breathing air purifier. The white background screen is used to display the real-time PM2.5 value. When the screen is off, it can be integrated with the body. Compared with the black background screen, it is really more beautiful. In addition, it is equipped with a background light, which has three colors of green, orange and red. You can judge the current air quality according to the color.

There is an icon of "five trees" near the bottom of the front of the fuselage, and a small line of Spanish "Jose Tronco" below it. This is the brand logo of breathing freely. The green icon and the air purifier are very compatible.

The top of the fuselage adopts a grid design, which is the air outlet of the air purifier. Although the grid is relatively large, the authorities have also placed a layer of fine filter screen under the air outlet, which can be used to prevent some debris, dust, hair, etc. from falling in. It is very useful for users with bear children at home.

The official ingeniously placed the key on the top frame, which neither occupies extra space nor affects the overall beauty of the body. There is a mode switch key and six LED indicators on the front frame. Click the mode switch key, you can cycle between extreme speed, sleep, automatic and manual.

There is a light sensor on the top rear frame, which can automatically adjust the brightness of the front display according to the surrounding light intensity. Below the sensor is the power key, which can be clicked to turn on/off the purifier. There is also a WiFi key on the left side of the power key, which is needed for network connection.

The smooth breathing air purifier adopts an innovative three side air intake design, which can provide greater air intake. Except the front, the three sides of the fuselage are occupied by dense meshes. However, only the lower half of the meshes on both sides of the fuselage are air inlets, and the upper half is only for decoration.

On the back of the fuselage, there is a buckle near the upper part. The green prompt of "opening the cover" is very conspicuous, which can facilitate the user to open the rear cover. Below the buckle is the PM2.5 sensor vent, and in the middle of the lower part is the power socket. In addition, there is a plug direction sticker. The details are very careful.

There are four universal rollers at the bottom of the purifier, which can facilitate the user to move the machine easily and move between rooms as required. The hidden roller design is adopted, so that you can hardly find its existence in daily use, improving the integration of the body.

The back panel of the smooth breathing air purifier adopts the magnetic suction design. There is a magnet on the top and two sides, which is very firm and more convenient for users to remove and install.

Dismantle the rear panel of the purifier. There is an empty filter cartridge at the top, which can be used with the formaldehyde removal super activated carbon filter cartridge to provide a stronger formaldehyde removal effect. Of course, this is not a standard configuration, and users who need it need to purchase another one; The laser PM2.5 sensor provided by Phantom Technology below the filter cartridge bin can quickly and accurately detect the PM2.5 concentration, and nearly half of the lower area is occupied by the standard haze and formaldehyde removal composite filter cartridge.

For an air purifier, the filter element can be said to be the most important accessory. The smooth breathing air purifier is equipped with a haze and formaldehyde removal composite filter element as standard. The outer layer of the filter element is also equipped with a dust screen, which can effectively remove particles, hair, pet dander and dust with a diameter of more than 0.3mm, and can effectively improve the service life of the filter element.

The haze and formaldehyde removal composite filter element of the smooth breathing air purifier uses the H13 level advanced HEPA filter screen, which is provided by the world-famous professional manufacturers 3M and Toray. It can filter PM2.5, pollen, allergens, and second-hand smoke. The single filtration rate for particles with a diameter of more than 0.3 microns is above 99.97%. Compared with the H11 or H12 level HEPA filter screen, it not only has a more efficient filtration efficiency, Moreover, the cost is much higher, so it is recommended that the purifier should be equipped with H13 HEPA filter screen; The innermost layer of the filter element is the activated carbon filter screen, which can remove harmful gases such as formaldehyde, toluene, volatile organic compounds and various odors. There is also a ring of rubber gasket on the top of the filter element, which can play a good sealing role.

There is also a filter element lock with sliding design under the filter element inside the purifier. The left side is unlocked, and the right side is in working status. The label is very clear. The user can understand it as soon as he reads it, and the user manual can be discarded.

In addition to the filter element, the fan is also an important part of the air purifier. The breathing air purifier adopts a DC brushless motor, which has a service life of up to 20000 hours. With a backward centrifugal fan, it can not only provide sufficient air volume, but also have a lower noise level.

This is the end of the introduction about the appearance and internal structure of the smooth breathing air purifier. Now we will enter the practical use experience stage.

Experience:

The installation of the breathing air purifier is very simple. As we have said before, it is basically just a matter of plugging in directly for use, but you can't really start with power on. Before that, there is still a small work to be done. The plastic film on the surface of the filter element needs to be removed first. If it doesn't have any effect of purifier, then it can really be powered on for use. Basically, each step of the operation instructions are labeled on the accessories or around the socket, which I believe can be easily installed even by small white users.

After power on, click the "On key" to start the machine, and then you can use the "Mode switch key" to cycle between extreme speed, sleep, automatic and manual. In daily use, we just need to switch to the "Automatic mode". The machine will automatically adjust the appropriate wind shield according to the PM2.5 concentration of the current environment to carry out purification work, which is very easy.

The smooth breathing air purifier also supports intelligent control. After the purifier is turned on, long press the "WiFi" button on the back of the body Press the "key" to enter the pairing mode, and then open the "Smooth Breathing" application on the mobile phone, and add the device according to the system prompts. After the pairing is successful, there will be a prompt on the application interface, and an icon of the "Smooth Breathing Air Purifier" will also appear on the "Device" interface of the application.

Enter the main interface of "Smooth Breathing Air Purifier", you can not only view the current operating status of the purifier, but also view the indoor PM2.5 index PM10 index, temperature, humidity and outdoor air quality forecast can see that the local air quality will be heavily polluted in the next few days. It's really time for this breathing air purifier to come here and breathe at home. This interface can also carry out remote control of the air purifier, and can switch between on-off, extreme speed, sleep, automatic and manual modes. Users can also manually adjust the six speed wind speed as required.

In the "Purifier Settings" interface, we can customize the name of the purifier, and also switch the front panel display screen and child lock function of the purifier. The purifier also supports firmware upgrade. The system lake will push new versions irregularly to keep the purifier in the latest operation state.

In the "Breathing" application, there are also three options: help, shopping mall and personal. The "help" option is divided into unpacking and installation, introduction to mobile phone application functions, user instructions, and common problems and solutions. It is introduced in detail in a video or graphic way, which is more detailed than the paper user instructions, If users encounter problems during use, they can first find solutions here.

Of course, for an air purifier, various functions can only be regarded as auxiliary, and the purification effect is the time to test the strength of an air purifier. The smooth breathing air purifier has an ultra strong purification capacity of up to 800 CADR and a minimum noise effect of 34 dBA. The official data is that it only takes 4 minutes and 30 seconds to clean a room of 25 square meters at a time. Whether it can really be "clean with a swish" or not, we will now enter the actual test phase.

Here, the noise of the purifier is tested. The initial ambient noise is 37.7 dBA. When the test instrument is directly placed at the air outlet, it can be seen that the noise in the sleep mode is 46.7 dBA. Of course, since the test is conducted in the home, this value is also for your reference only, and it is impossible for us to put our ears close to the air outlet in daily use.

Here I simulated the daily use process, and conducted the noise test again at a distance of about 1.5m from the purifier. This time, the noise test was conducted at the sixth gear wind speed of the purifier. The initial ambient noise was still 37.7dBA, the first gear wind speed noise was 37.4dBA, the second gear wind speed noise was 38.3dBA, the third gear wind speed noise was 41.7dBA, the fourth gear wind speed was 52.2dBA, and the fifth gear wind speed noise was 57.7dBA, The wind speed at gear 6 is 59.5dBA, and there are few air purifiers that can reduce the noise at 60dBA. At this distance, you will not feel the operating noise of the purifier under the first gear wind speed (sleep mode) and the second gear wind speed, and you will not feel the operating noise of the purifier until the fourth gear is above.

Through the air detector in hand, the PM2.5 display value of the smooth breathing air purifier and the primary air purification capacity were tested, and the PM2.5 display value of the tested purifier was basically consistent with the air detector; Continue to test the primary air purification capacity of the air purifier. The current indoor PM2.5 value is 75 through the air detector. When the air detector is placed at the air outlet, it can be seen that the PM2.5 value rapidly drops to 1, so the primary purification capacity of the air purifier is very good.

Here, the purification capacity of the smooth breathing air purifier was actually tested. Since the purifier had been running for a period of time, the indoor PM2.5 value was at a low level, so a cigarette was ignited for testing. In a room with a test environment of 10 square meters, the doors and windows are closed. When a smoke is burned out, turn on the purifier again. It can be seen that the PM2.5 value in the room is 324, which has reached the standard of serious pollution. This also proves that the harm of second-hand smoke is obvious. For people like me who do not smoke, The choking smoke smell has been clearly felt in this confined space. At this time, the screen background indicator has also been displayed in red.

First of all, we use the commonly used automatic mode. The initial PM2.5 value is 324. After starting up, the purifier automatically adjusts to the maximum windshield operation. After one minute, the PM2.5 value quickly reaches 190. After three minutes, the PM2.5 value has dropped to 75. The screen background indicator changes from red to orange, and finally to green. At this time, the indoor air quality has reached an excellent level, After 5 minutes, the PM2.5 value dropped to 35. At this time, the purifier has been automatically adjusted to operate at the first gear wind speed, and the operation of the machine is hardly felt.

In order to test the maximum purification capacity of the smooth breathing air purifier, a smoke was ignited again here, which is still a 10 square meter confined space. Here, the "extreme speed mode" of the purifier is used to test the purifier's capacity. When the smoke is burned out, the current indoor PM2.5 value measured by turning on the purifier is 382, and the maximum purification mode is turned on.

When the "extreme speed mode" of the purifier is turned on, the noise is still obvious, but the purification efficiency is also very strong. After only 2 minutes, the indoor PM2.5 concentration has rapidly decreased from the initial 382 to 126. After 3 minutes of operation of the purifier, the indoor PM2.5 value has dropped to 55. After 4 minutes of operation, the PM2.5 value has reached 17. After 8 minutes of full effect work, The indoor PM2.5 value has reached 1, which is consistent with the test data of the hand air detector. At this time, the indoor air quality has reached the optimal level.

Conclusion:

    As an air purifier launched by Hammer Technology for the middle and high-end market, the ChangBreath air purifier not only has the super purification capacity of 800 CADR, but also has a noise as low as 34dBA. Compared with similar purifiers, it has a high cost performance. Of course, it would be better if the price could be cheaper. Moreover, after the actual use experience, the smooth breathing air purifier is very good both in terms of actual purification capacity and noise control. In addition, its simple and round appearance makes it easy to integrate into various home environments, which can be regarded as the last purifier product with both appearance and strength. If you have to say that it has any shortcomings, it is relatively large, and you can't ignore its existence anywhere, especially in a small bedroom or study, which still takes up more space. Of course, the choice of air purifier should be determined according to the actual needs of individuals. Pay attention to the CADR value of the purifier, noise control and filter element level. I wonder if you like the first purifier of Hammer Technology. Let's talk about your views.
