Recently, the Shanghai Bureau of Quality and Technical Supervision released a random inspection and supervision result of air purifiers, which attracted wide attention once it was published ENVION、 A total of 4 batches of products of three dada and millet were judged as unqualified, and the main problems involved noise, solid pollutants, clean air volume, etc. Among them, the quality problem of the well-known millet purifier is the most serious. The unqualified items involve "clean air volume of solid pollutants" and "noise", which are marked "serious quality problem" by Shanghai Quality Supervision Bureau in the remarks.

At the moment when the air haze is getting worse, how to correctly identify the quality of various air purifiers on the market has become a core concern. I was lucky to participate in a 720 Environment Treasure Plus air quality intelligent detection box on Lei Feng.com, which can accurately measure the temperature, humidity PM2.5 value, noise level and formaldehyde content, it is very convenient to use 720 Enviro Bora to test the quality of the selected air purifier.

The package box of 720 Environment Treasure is very emotional. Instead of using traditional product photos or product words on the front, it uses the slogan Slogan "the best gift for life" to arouse the writer's curiosity. Only one 720 logo is printed on the upper left corner, which is full of literature and art.

The side of the box is marked with the relevant information of 720 Environment Treasure Plus. The one I received is shell white, and the model is EM1001.

In terms of the configuration list of the whole machine, 720 Environment Treasure is also very simple. There is only one instruction manual, Micro USB power cord, Environment Treasure host and sticker. An additional sticker gives cold and cold technology products a warm feeling of naivety.

In terms of data cable, 720 Environment Treasure uses a common Micro USB interface, which is common to the Android data cable in daily use, and is very convenient.

The shell white host adopts a simple design style, with only one 720 logo printed on the front. The groove on the upper right corner is the air inlet. At the same time, the upper right corner is also equipped with a built-in LED light. When charging, white light will be emitted, which echoes the shell white, simple and clean.

720 Environment Treasure is equipped with indicator status bar at the top, which is respectively noise detection microphone, Bluetooth indicator, PM indicator, formaldehyde indicator and noise indicator. During the air detection process, each indicator will flicker according to the item being detected.

The column at the bottom of the fuselage is printed with the introduction of relevant parameters of the product and the fence type opening. It can be seen from the introduction of parameters that the rated voltage of 720 Environment Treasure is 5V, the rated current is 1A, and the built-in battery capacity is 3600mAh.

On the right side of the fuselage are four hidden LED indicators, power switches, and Micro USB charging ports, USB At the output port, in the charging state, four hidden LED indicators will jump and flash, which can display the remaining power of 720 Environment Treasure. To solve the portability problem, the host integrates the mobile power function and ambient air detection function, so that users can not only use 720 Environment Treasure to detect the air quality, but also use it as a mobile power to charge mobile phones and other portable devices in an emergency, One machine can be used for many purposes. It is very powerful to carry with you.

Download the app "Environment Review" of 720 Environment Treasure, and the software guide page prompts several application scenarios of Environment Treasure: testing PM2.5, testing the environmental hazards of smoking, testing the values of formaldehyde after the decoration of new houses, etc. Users can check the ambient air quality at any time through the 720 Environment Treasure they carry, and choose to enjoy the fresh air environment.

When using Environment Treasure for the first time, you need to connect the power supply to charge the Environment Treasure. You can activate the device in the charging state. When the device is activated, you can pair the mobile phone and Environment Treasure again. Environment Treasure is used for device interconnection and data transmission through Bluetooth mode.

In consideration of the improper operation of the user's first matching, the Environment Review kindly prompted the solution on the pairing failure interface to reduce the user's learning cost. The user only needs to operate according to the solution prompted by the software, and then the correct operation can be achieved. After the pairing is successful, the page will prompt.

In terms of the operating guidance of the app, the environmental review is very good. Before each step of operation, a targeted text introduction will be given, so that the user can understand the specific role of each function button. At the same time, on the help information page, several commonly used data range definitions are also built-in, and each data is basically classified according to the national standards, It is convenient for users to intuitively understand the assessment of air environment quality.

Before use, the author first extracted a set of official data built in the weather forecast software. The data was from Chinese weather. At this time, it showed that the outdoor temperature in our region today was 7 °, the somatosensory temperature was 7, the air quality was 53, of which PM2.5 was 34, PM10 was 53, and the outdoor humidity was 95% in rainy days.

The author starts monitoring indoors with 720 Environment Treasure. The whole detection process takes 10 minutes. After starting the detection, Environment Treasure will focus on temperature, humidity, noise PM、 There are five values of formaldehyde in total for environmental testing. During the testing process, the data will fluctuate. After the testing is completed, the data will take the average value, which is relatively accurate. Through the author's indoor environmental data testing, the final display temperature is 13.7 ℃, formaldehyde 0.07 mg PM 56, humidity 66%, noise 73 db, which is roughly the same as the data extracted from the weather forecast in advance by the author, especially the PM and humidity values are very similar. Considering that the official data is the outdoor mean value in rainy days, while the value extracted by the author is the indoor value, 720 Environment Treasure performs very well in terms of accuracy.

720 Environment Treasure supports two air detection modes, namely comprehensive measurement and formaldehyde special detection mode. Users can select corresponding modes for air quality detection according to their own needs, which is very convenient.

Here are two simple tests for 720 Environment Treasure:

Negative ion air cleaning test I:

Test environment: Air purification detection in the packaging box

Equipment: 720 Environment Treasure+Air Angel anion air cleaner

First, the author opened 720 Environnement Treasure to extract the ambient air data before anion air purification. After extraction, the author started to open Air Angel anion air purification. At the same time, in order to use the method of packaging box coverage, negative ion air purification was carried out in the closed environment. At the same time, the air comprehensive detection function of 720 Environnement Treasure was opened again.

The results of test 1 show that before the anion air purification, the PM in the nearby air environment is 34. When the anion air purification of Air Angel starts, The PM value dropped rapidly. Finally, the comprehensive test data of 720 Enviro Bao showed that the PM in the air inside the box was 0. During the whole process of air purification and 720 comprehensive test, it was very intuitive to see that the PM number continued to decline. During the whole air test process, 720 Enviro Bao was unusually sensitive and the air quality test sensitivity was high.

Adsorption filtration air cleaning test II:

Test environment: Indoor air purification test

Equipment: 720 Environment Treasure+three dads adsorption filter air purifier

Test 2, the author used adsorption filter air purifier to test. Three father air purifiers used bottom air intakes. Indoor air was filtered through the bottom air intakes of the air purifier. Pollutants in the air were filtered through the internal filter screen of the air purifier, and purified air was discharged from the top air outlet of the air purifier, The author places 720 Environment Treasure at the air purification air outlet for air detection. First, open 720 Environment Treasure to open the comprehensive air detection. First, detect the relevant data before purification, and then open the air purifier. You can see the data changes detected by Environment Treasure very intuitively.

During the use of adsorption filter air purifier, there will be noise. 720 Enviro is very sensitive. In addition to the intuitive change of PM value, the temperature and noise values will also change directly during the detection process. In the whole purification process, 720 Enviro also performs exceptionally well, and each value change is very sensitive.

Experience summary:

As a household air environment intelligent detection box, the 720 Environment Treasure Plus has various functions, including temperature, humidity, noise PM、 The one key quick detection function of five air indicators of formaldehyde can synchronize the detection results with the mobile phone screen by matching with a smart phone, and combine the functions of the mobile charging bank into one, further improving the portability of 720 Environment Treasure. When users travel, it is very convenient to use one machine for multiple purposes.
