Under the dome, in the haze, when "breathing" becomes unbearable pain in life, where should we go? How can we protect ourselves in the face of smog, a vicious and ubiquitous enemy? As a kind of cloth clothing, we can do nothing to change the general environment. We can only try our best to change the small environment around us, and try to prevent ourselves from being exposed to high concentrations of PM2.5. The lowest threshold and more effective measures are to use masks and air purifiers, which can separate us from PM2.5 as far as possible outdoors and indoors respectively.

Today, the author would like to introduce a household air purifier product - new oxygen air purifier. It uses nanometer photocatalysis technology to completely decompose formaldehyde, and imports 3M filter element to remove pm2.5. It is equipped with industrial grade sensors, which can display PM2.5 and tvoc values in real time with a 7-inch LCD touch screen. It can also be remotely controlled by human-computer interactive APP no matter where you are, The machine can be turned on or off, and mode switching, wind speed adjustment, timing switch and other operations can be carried out. When you are not at home, you can also care for your family to breathe.

With it, you can finally breathe freely under the dome.

The body of the new oxygen air purifier received by the author is white, which looks clean and tidy. According to the official introduction, there are other colors to meet your personal needs. The rectangular shape shows maturity and steadiness. On the oblique section above the front is a large 7-inch touch screen, where almost all information and operations are displayed and carried out. Next to the screen is a round on/off screen key, which is the only physical key on the whole body. At the bottom of the front is the air inlet; There is a handle on both sides of the upper back of the product, which is convenient for the user to move the machine. The nameplate information of the product is in the center, and the bottom is the power cord plug. If four universal rollers can be designed at the bottom, it will be easier to move the machine.

Take a closer look at the bottom air inlet. The air inlet grille is designed with a primary filter screen, which can "keep hair, large particles, etc. out of the door"; The air outlet is designed to the top of the product, which is behind the oblique section where the touch screen is located. The clean air after layer upon layer of purification is continuously released from here, allowing you to enjoy the beauty of free breathing.

There are sensors on both sides of the machine and side doors for replacing internal consumables. According to the official introduction, the built-in sensors of the machine include two types: dust sensor (PM2.5) and odor sensor (TVOC). The former can sense cigarette smoke, pollen, dust and other particles, and detect the degree of air pollution; The latter can sense the odor of cigarettes and pets, and is also very sensitive to the odor of pesticides, cosmetics, sprays, alcohol, or sudden changes in temperature and humidity.

When the consumables inside the machine reach the upper limit of service life, we need to replace the consumables in time. At this time, we need to open the side door. The side door is designed with force points, which can be easily opened.

In addition to the primary filter screen designed at the air inlet, the new oxygen air purifier also has three built-in filters: HEPA high-efficiency filter screen, activated carbon filter screen and the exclusive nano catalytic screen, each of which has its own advantages. Specifically, HEPA filter screen made of laminated boron silicon micro fibers can effectively remove 0.1 micron and 0.3 micron particles; Activated carbon is a common odor adsorbent, and it can well absorb formaldehyde.

The unique nano catalytic network of the new oxygen air purifier generates chemical reaction through the irradiation of the internal catalytic light source to generate hydrogen and oxygen free radicals with strong oxidation, which can decompose almost all organic substances and some inorganic substances harmful to human body and the environment.

After the new oxygen air purifier is powered on, it is accompanied by wonderful startup music. The system starts about 30 seconds later. You need to click the round virtual key on the screen to start the purifier. For the first use, you need to set the WiFi network connected to the purifier, and bind the purifier activation to the mobile phone.

It has to be said that this touch screen equipped with the new oxygen air purifier is absolutely a highlight. It has great visual impact, which is not only beautiful but also practical. It can display the indoor PM2.5 and TVOC concentration in real time, and then convert the indoor air index, which can be displayed intuitively in numerical form. All operations are operated through this screen. Touch has been accepted by everyone for a long time, so it's very friendly to start with.

In addition to the large screen of the new oxygen air purifier itself, it also has a second screen, that is, your mobile phone. As long as your mobile phone and the purifier are bound through the APP, you can remotely control the Flesch in your home through the mobile phone APP at any time and anywhere. Of course, the premise is that your purifier is normally online.

The color matching, function setting, display content, etc. of the mobile phone APP interface matching the new oxygen air purifier are very close to the built-in screen display layout and content, which are very intuitive. Personally, it is convenient to check the use of the purifier filter screen through it. If the filter screen needs to be replaced, the APP will automatically remind you. Personal suggestions can be added with timing function.

Of course, the convenience of intelligent control can add more points to the new oxygen air purifier. However, as a purifier product, its core competitiveness is naturally its ability to purify air, followed by power consumption and noise, which are also some indicators worthy of attention by consumers. The relevant parameters of this product found by the author on the new oxygen air purification organ website are shown in the figure above, of which the two most worthy of our attention are the air clearance and formaldehyde removal CADR. In terms of parameters, the purification capacity of this purifier is still considerable.

Due to the limited evaluation conditions of the author, it is impossible to make a very professional evaluation on all aspects of this purifier. Now I will mainly evaluate it from four aspects: actual purification capacity, wind speed (which can reflect its purification efficiency laterally), noise, and power consumption.

It should be noted that the products sent by the manufacturer for the first time failed in the trial, and the products sent by the manufacturer for the second time were pink color matching, so some purifiers evaluated below are pink.

The living room in my home covers an area of about 30 square meters, which is just one of the applicable areas of the new oxygen air purifier (30-40 square meters). Light three cigarettes and two incense sticks. Within a few minutes, the whole living room becomes smoky.

In the above figure, the left side shows the indoor air quality before lighting a cigarette. The PM2.5 value measured by 360 Air Testing Master is 100, and the new oxygen air purifier screen displays 120. The difference between the two values is acceptable; On the right side are lit cigarettes and incense for about ten minutes. The values measured by 360 Air Testing Master can be seen from the color displayed. At this time, the indoor air quality has dropped to the red alert state, and the pollution is very serious. At this time, start the new oxygen air purifier and let it run at full speed.

The above pictures are taken by the author in four different periods when the new oxygen air purifier is working. At first, I set it to sleep mode, and the machine speed is slow. Then I set it to strong mode, which can obviously feel that the wind speed of the machine is greatly increased, and the noise is also increased. Finally, I set it to automatic mode, and it is obvious from the screen display that with the operation of the purifier, The polluted indoor air changed from heavy to medium, good, and finally excellent, and the whole process lasted about 20 minutes from heavy to excellent. Such purification ability is relatively efficient.

Another hardware indicator that determines the air purification capacity of the purifier is the working efficiency of the built-in fan. The international standard is to ensure 5 air changes per hour in the applicable area. In terms of parameters, the new oxygen air purifier can change air 10 times per hour in a room of 30 square meters. Although I have no equipment to test the air volume of the fan, testing the wind speed of the fan through the anemometer can also reflect the working efficiency of the built-in fan of the purifier from one side. There are six working modes of the new oxygen air purifier: automatic, sleep, quiet, comfortable, efficient and powerful. The above figure shows the wind speed values measured by me in five modes except the automatic mode, The results are 1.321, 2.140, 2.942, 3.336, 4.432 respectively, with the unit of m/s. The maximum wind speed in the strong mode is still a certain distance from the maximum wind speed of another brand of purifier in my home, and the performance of the fan of the new oxygen air purifier is in line.

During the noise test, because my home is located in the center of the downtown, and there are a lot of cars and streams outside, the environment itself is quite noisy. At about 3:00 p.m. during the test, the ambient noise measured was 55.9 decibels. The noise under the five working modes of the new oxygen air purifier were 57.1, 58.7, 62.3, 68.6, and 74.5, respectively, The working noise in the strong mode is basically the same as that in the strong mode of the purifier of another brand in my home. In the actual experience, when you rest at night, put the new oxygen air purifier in the bedroom and start the sleep mode, the noise emitted by the purifier when it works is almost negligible.

The last part is the power consumption test. The figure above shows the measured power of the new oxygen air purifier in each mode. The measured data is somewhat different from the official parameters, and is slightly smaller overall. The high efficiency mode and the strong force mode are consistent with the official parameters. The strong force mode is 65.1 watts, which is the maximum power of the new oxygen air purifier. It is calculated according to the maximum power, Keep the purifier running in the strong mode 24 hours a day, the daily power consumption is 1.56 kilowatt hours, and the daily power consumption is 0.87 yuan based on the electric charge of 0.56 yuan per kilowatt hour. Of course, in real life, it is impossible and unnecessary for the purifier to keep the high level running state all the time. The most common mode is the automatic mode. If the indoor air pollution is serious, the power consumption may be higher at the beginning. After the indoor air quality improves, the purifier will automatically reduce the working power, and the power consumption will naturally decrease, so its power consumption is completely acceptable, Even if it is used frequently.

Through this trial, I think that the new oxygen air purifier has two advantages over similar products on the market: the first is its stronger purification capacity. The filter element of general purifier products is activated carbon and HEPA filter screen. Although this combination can purify dust, particles and other pollutants in the air, However, the purification effect on other pollutants in the home environment, such as formaldehyde, benzene and other harmful substances volatilized from furniture, is extremely limited. At most, they are absorbed by activated carbon, but they will still volatilize in some cases. The new oxygen air purifier has an exclusive built-in nano catalytic network, which can completely decompose formaldehyde, benzene and other pollutants without secondary pollution; The second advantage is the remote control function. Through the mobile phone APP, you can know the air condition at home at any time and anywhere, and then remotely control the working mode of the purifier according to the needs. It is very convenient. This networked remote control function will also be the development direction of such products in the future.

To care for the health of your family, you should first pay attention to the indoor air quality. After all, our home is the place where we stay most every day. Today, the problem of air pollution is becoming more and more serious. It has long been a strong need for Chinese people to buy an air purifier for their families. If you also want to purchase an air purifier product to improve the air condition in your home, the new oxygen air purifier is a good choice. It will help you remove all kinds of pollutants in the air of your home, so that you and your family can enjoy the beauty of free breathing again.

With the new oxygen air purifier, you can breathe freely under the dome.
