[Preface]

After winter, according to the past practice, the air purifier came on the scene. As we all know, in some parts of northern China, the previous winter was affected by the haze weather, and the air purifier came into being. However, unlike the past, Hammer Technology has also set foot in the field of air purifier this year in addition to mobile phones, ChangBreath Air Purifier is the first smart home work of ChangBreath Technology, a brand under its name. The new product has attracted many fans of Laoluo before it was launched. Laoluo also said that he was very satisfied with ChangBreath Smart Air Purifier. So what about this air purifier? Experience it with the author!

[Unpacking and Uncovering Secrets]

When I received the express delivery, I was shocked by this huge object. The outermost film protection, kraft paper packaging box surface printed with five pine trees, it is not difficult to see the concept of close to nature.

It was thought that the large volume of the box was to protect the internal host. After unpacking, the volume did not decrease much. Length: 384mm, height: 819mm (including casters), width: 384mm, net weight: 17kg (including filter element). Fortunately, considering the weight, wheels are installed to facilitate the placement. The overall white tone is mainly used, and a round white LED screen is collocated. It looks very comfortable, and the colors are versatile at home. This is why most smart home products are mainly white, and the edges are cleverly rounded. Although the size is too large, But it is not eye-catching; In addition, there is no elevator in the old house. Thank the express master for helping us move up to the sixth floor.

The difference between the front and the back is that the content of the back is more abundant. The green decoration and the grid design of the lower part make the whole look more comfortable than the slightly monotonous front.

The opening of the rear shell can be seen through the mark that it is detachable, and the humanized design of the groove is convenient for operation.

There are air inlets on both sides of the Changbreathing air purifier, which are full of orderly grids. The layout is reasonable only to inhale more air in a certain time and effectively purify. This is related to the huge volume. Later, the author will explain why the volume of Changbreathing air purifier is far more than that of similar products on the market.

The layout of the air outlets at the top is not much different from that of the fuselage. Of course, the air inlets at both sides are much larger than that of the fuselage in a limited space. At the edge are several mode indicators and the only mode switch button. The indicators can be roughly divided into: extreme speed mode, sleep mode, automatic mode, manual mode, The right side is the child lock indicator light and the filter element status indicator light. The biggest highlight is that the design of the mode switch button is almost integrated with the edge, which is smooth without convexity, and the pressure is moderate.

The opposite back is the power on/off button, WiFi indicator light and button.

At the bottom is the power interface. The rated voltage is 220V, and the rated power is 98W. Of course, there are differences according to the power under different modes. The specific power will be revealed below.

Many people will feel that the whole machine is too large, and the weight is up to 17KG, so it is really necessary to install a universal wheel at the bottom for home use. It slides smoothly and is very quiet, but it can not be fixed. There is another big toy with a bear child in the house, but the four wheel design does not have to worry about the situation of falling down and pressing people due to the push of children, The design of wheels also greatly facilitates the adjustment of placement position.

The external structure is basically the same from top to bottom. A simple summary: the white and versatile colors, together with the round appearance design, make the appearance really good, and the home display also has a little more simple style. Moreover, the wind enters from three sides, and the LDE small screen displays on one side. The whole machine is designed generously and appropriately. Next, let's look at the internal structure.

The back cover can be removed by fastening the back cover buckle without any tools. The integrated design of the back cover does not have any screw holes. In addition to the buckle fixation, the two magnets on the panel also contribute a lot.

The most important thing about a purifier is its filter element. The smooth breathing air purifier filter element is placed at the bottom, and the surface is equipped with a dust screen to filter large particles of dust and hair, which can greatly extend the service life of the filter element.

Fasten the clasps on both sides to remove the dust filter screen, and the holes are dense. Although it does not play a decisive role in air purification, the effect of filtering large particles of dust before filtering is excellent. It can also effectively prevent animal hair from being sucked into the filter to block the filter element, and ensure the normal operation of the filter element.

Before taking out the filter element, push the filter element knob to the far right to take out the filter element.

According to the official data of Hammer, the long-life high-quality filter element used by Changxing Intelligent Air Purifier is provided by the world-famous professional manufacturers 3M and Toray. Most of the reasons for the strong purification capacity are inseparable from this strong filter element. Not only that, but compared with the carbon cloth filter screen used by other similar products on the market, The smooth breathing intelligent air purifier adopts a columnar carbon filter screen, which can effectively avoid the sour odor caused by long-term use.

The white outside of the filter element is HEPA filter paper, and the black area is an activated carbon filter element that can effectively filter and purify formaldehyde. The activated carbon content of the filter element is 1.1kg, and the spread area is about 154 standard football fields. If you have seen the relevant interview of Lao Luo, you know that he is quite satisfied with this; Generally, the service life of the filter element is 6-12 months. When it needs to be replaced, its replacement indicator light will always be on, and the purifier will continue to emit a special sound to remind the replacement. However, the service life is related to the service environment, and this data is for reference only.

After looking at the bottom filter element, it can be opened in the upper part of the fuselage. This position can be additionally equipped with a "formaldehyde removal super activated carbon filter element" according to the environment. Generally, it is very practical when new or old houses are just decorated.

Apart from the filter element, the fan can be said to be the biggest highlight of the smooth breathing air purifier. The DC brushless motor backward centrifugal wind wheel is used. The wind wheel is equipped with EPP environmental protection materials. Lao Luo's most satisfied 800CADR relies on this powerful mechanical core, and also because of this rapid purification effect, the smooth breathing air purifier has attracted much attention.

It can be seen from the working principle diagram that the smooth breathing air purifier adopts an innovative three side air inlet design. The overall structure is not complicated, with large air volume, fast purification efficiency, and it is said that the operation noise is very low. So many highlights, the author can't wait to experience.

Experience

After the power supply is turned on, the LED display on the front panel of Breathing Free brings two kinds of information, the value is the PM2.5 concentration index, and the excellent indoor air quality is represented by more intuitive three color changes. The "green, orange and red" air quality is getting worse in turn, and the specific changes can be witnessed together next.

As a smart home product, it is basically used with the corresponding APP, and the smooth breathing air purifier is no exception. After downloading and registering through the official two-dimensional code, network pairing is carried out in the current use environment to achieve real-time monitoring, remote operation, etc. The whole matching process is also relatively simple, but does not support 5G networks, so users of dual band routers at home, Remember to select 2.4G network for pairing.

After matching successfully, you can not only see the indoor air quality, but also know the outdoor air quality and the weekly air quality forecast through the APP. Both the color matching and the data display style are relatively fresh. This point, whether it is the Wukesong LOGO or the green color matching, gives a feeling of environmental protection, green, fresh, and flat data display style is also very intuitive.

In addition to viewing data on the APP, it can also perform mode switching, switching equipment, etc., which is the same as the operation of the equipment itself. By clicking the corresponding mode at the bottom, it can perform quick switching. From the first gear to the sixth gear of extreme speed, sleep, automatic to manual, it can directly and quickly operate. The difficulty factor is zero. Through the APP, you can also learn about PM2.5 PM10、 Temperature, humidity, purification time, purified air volume and other relevant data are collected comprehensively.

Of course, in order to test how magical the smooth breathing air purifier is, the author lit the cigarette for a month and felt really good, but when he saw the value and the red indicator light, he definitely did not want to experience the second time. From less than 10 seconds of cigarette lighting, the value soared from single digits to three digits, and the color of the indicator light also changed to a conspicuous red, It would be more perfect if it was equipped with an alarm tone.

The test process also found that the APP value was different from the host display, and the author understood that the purifier had purified the surrounding air through the purifier in a short time from the time when the value was collected by the purifier to the time when it was transmitted to the APP. The APP value has a delay, which on the one hand reflects the high efficiency of the purifier, On the one hand, it also feedback that the numerical transmission process is closely related to the network of the current use environment, and the host display should be the main display.

If you are a regular smoker, please consider your family when you see this value. The harm of a cigarette is far greater than what you think. The whole process is automatic purification, PM2.5 has recovered from a value close to 600 to a green and healthy state in about 10 minutes. Such efficient purification speed benefits from the strong 800+CADR, which can purify 800 cubic meters per hour. Some people may wonder whether this value means that the noise is also very strong?

In the automatic mode, the noise value detected during high-speed operation is 51.8 decibels. Of course, there is an error between the environmental impact and the detection instrument, but the deviation is not very large. It is almost the same as the manual third gear noise value given by the official. Every five minutes, a space of 13 m ² is cleaned. The author places the living room with an area of about 20 m ². It takes about 10 minutes from serious pollution to good quality, The noise hovers at 50 decibels; Then the question comes again. Many people will ask, it is not always necessary to run at high speed at home. What about the data of sleeping at night and sleeping mode? How much is the power consumption?

Through the smart socket with power detection function, you can see the various values of the smooth breathing air purifier in the sleep mode. The power consumption is 7.5W, and the noise is 37 dB. I remember that a brand said when promoting the power consumption, that the power consumption is as low as one kilowatt hour a night, while in the smooth breathing sleep mode, there is not even a fraction of a night, and one kilowatt hour power can be used for several nights.

The power consumption reference of gear 1 and gear 2 is about ± 1W due to acquisition by non professional equipment.

3rd and 4th gear power consumption reference.

5th and 6th gear power consumption reference.

The first gear is equivalent to the sleep gear. The purification capacity is 205 CADR, which is also the lowest level of power consumption. The fast gear is the same as the sixth gear. The purification level of 800+CADR is the highest level. The power consumption is about 100W, and only one kilowatt hour is used for 10 hours a day. The energy consumption level is truly energy-saving and efficient.

In addition, practical functions such as child lock and tilt power-off also take into account the use environment of different families, which is very thoughtful. Undoubtedly, Laoluo has created a good home product that is truly suitable for all kinds of people.

Summary

Experience more than a week, and breathe freely. The appearance of the air purifier gives you a simple and comfortable feeling. Although it is a little big, the versatile design is not unusual in the home. Being a craftsman, with a high face value, it can bring fresh air, health and good mood; The structure design is generous and decent, the operation is also very simple, and the efficient 800+CADR purification effect is also completely marked with a cost-effective label. The reasonable design of the three side air inlet makes reasonable use of space, and the power consumption is also low, environmental friendly. Both the purification speed and the noise level are very pleasing. In addition to mobile phones, Lao Luo has entered the field of smart home, And the first product I think is quite successful
