With the continuous improvement of people’s living standards, industrial pollution has been aggravated, and our ever-present environmental quality has experienced an unprecedented crisis. In recent years, major bustling cities have been covered by haze for a long time, PM2.5 explosions, and various The news of lung diseases is increasing day by day. When we urge everyone to take good care of the environment, we also have to think more about our own health.
As a result, various types of smart air purification and detection equipment are widely used as an aid in people's homes; whether they are air purifiers for home use or air detectors that are small enough to carry, they can give us good health. Provide a certain degree of protection.
The DNC Dongyan Breathing Purifier that Xiaobian showed to everyone today is a healthy travel product created by the China Health Industry Leader East Research Group in line with the concept of innovative services and caring for the health of users. This breathing purifier differs from traditional masks in appearance. It uses a medical-grade silicone face mask to better fit the face and isolate the outside air. In terms of performance, the motor and filter in the interior of the respiratory purifier have a common role in achieving a more thorough purification of the air; the next step is to start the evaluation tour with Xiaobian.
Unpacking
The DNC Breath Purifier is packaged in a classic white gift box. It is a gift to care for health and it is very good for family and friends. The front of the box is the name of the product and the appearance of the logo. The back is the function of this breath purifier. The features and working principle are briefly described, allowing users to learn about the product for the first time.
The packaging box adopts the opening method of the flip cover, and it can be seen that the purifier and the accessories are placed inside the box with a separating fault. The visual effect is relatively neat and maximizes the use of space resources within the box.
In addition to the breathing purifier itself, the accessories section also includes a spare filter, manual, four detachable lanyards, charging cable, and storage bag. In general, the accessories section is still quite satisfactory, but the spare filter can be used as a bright spot to extend the use of electric masks.

Show details
At the bottom of the upper cover of the respiratory purifier is the LOGO logo of " DNC ." " Natural Life " also reveals the original intention of this product to protect life with technology; the above is an array of densely ventilated and ventilated holes through which outside air enters. Breathing purifier to go. The outer frame of the mask is made of ABS material, which is not only a beautiful appearance value but also a touch feel.
The product is called an electric protective mask because it not only works on the principle of filtered air, but also contains a high-speed rotating motor to increase the air filtering effect; the small button on the edge of the fuselage is the motor power. The switch button can realize two-speed switching of the motor rotation speed. Each speed mode corresponds to a different use environment of the mask. For example, different speeds can be switched under slow walking and running conditions.
A layer of medical-grade silicone mask is designed around the outer ring of the electric respirator. This material is soft and comfortable and fits closely with the face. Compared with the traditional mask, it avoids the disadvantages of retaining the gap on the edge of the mask. After wearing it for a long time, this silicone material does not have the same discomfort.
The outer cover of the respiratory purifier is fixed to the host by three magnets, which can be easily disassembled; after dismantling, the green and high-efficiency filter on the machine can be seen, which can effectively filter fine particles in the air. Dust, PM2.5 and other harmful substances, and send fresh air to the inside of the machine.
The filter can also be directly disassembled by hand. Generally , it can be used for 5-7 days in an environment where the PM2.5 value is around 200. The warmer part of the breathing purifier is provided with a replaceable filter. After removing the filter, you can see that a motor with a turbine structure is installed inside the machine to increase the flow of air. A detailed introduction to the small series will be given later in the dismantling section.
The edge of the respiratory purifier is designed with a USB interface, the time for connecting to the power adapter for charging is about 2.5 hours, and the full battery life is about 5 hours. In addition, the purifier also supports the use of a mobile power source for charging. Solve the user's dilemma of using a mask suddenly out of power outdoors. During the charging process, the status indicator light on the front of the breathing evolver will appear red.
Under normal working conditions, the indicator's color is green flashing.
The four elasticized lanyards in the accessories can be used for both the earhook and the headgear of the electric mask depending on the length; the personal test of the wearing style and the traditional mask is not much different. After use, there will be a sense of discomfort at the root of the ear; it is recommended to increase the width of the lanyard and wear it in a head-to-head manner. This will reduce stress and resolve the above problem.
The respiratory purifier can be carried in a storage bag and has high portability; the user can carry it along on the way to and from work or on the go, so as to prevent the wearer from using when the air pollution is severe.
Detailed disassemble
Xiaobian, but a DIY person, coupled with the nature of the work, how can we hold back and do not open to understand the internal working principle? In the dismantling process, everyone must pay attention to the fact that dirt and other contaminants cannot be mixed into the machine.
Unscrew the six screws on the edge of the machine, and gently open the back cover part to see the circuit structure inside. Xiao Bian thinks the space inside is still quite large, and it can fully accommodate the next air quality detection device. Let users always understand the air quality around them, so as to achieve a multi-functional machine, do not know why the manufacturers did not design? May be the cost of the cost of it.
There are many rotating blades on the motor at close range. According to the aerodynamics principle, with the three-dimensional structure of the purified air duct, the exhaust gas can be effectively eliminated from the bottom without blowing the air flow to the face, so that the bacteria cannot breed. These functional designs are not visible in ordinary pollution prevention masks. Many times when we wear ordinary masks, we breathe in the air we just called out and the secondary pollution is serious.
The inside of the machine contains a circuit board for switching the speed and control indicator of the motor, and two lithium-ion polymer batteries. In fact, you can manually DIY yourself and replace this larger capacity battery with this one. Longer use time.
Many friends may mistakenly believe that when the motor inside the purifier rotates, it will produce vertical wind, which is not the case; according to the unique shape of the fan, the motor will generate horizontal swirling wind around it, in order to filter it. The completed fresh air exchanges perfectly with the exhaled exhaust gas of the population.
Speaking of this, Xiao Bian still has to put forward some reasonable suggestions. First of all, after a long period of use, the motor will inevitably have dust and impurities in it. The cleaning process is unavoidable; however, there is no standard cleaning fluid inside the packing accessories. Practical devices such as brushes need to be improved. Secondly, the six tiny screws used to purify the breath are difficult to dismantle. After many operations, there will be a situation where the screws are lost or slipped. It is also suggested that the mask be locked by a completely mechanical structure to reduce the disassembly troubles.
Test principle
The northern cities where Xiao Bian is located rarely have severe air pollution in the summer. When it is winter, it is often covered with haze. In order to verify the actual effect of this breathing apparatus, Xiao Bian ignites in a sealed environment. A cigarette was detected by a master of air detection with PM2.5 values ​​as high as 500 .
We all know that only fine particles of PM2.5 can't be blocked with activated charcoal or cotton cloth , and only H13 or higher HEPA can really filter it.
After lighting up and burning out a whole cigarette, after turning on the purifier for 25 minutes continuously , the PM2.5 value detected by the air master has been reduced to below 100. It seems that the practical effect of this machine is really good. Users can not only protect themselves against air pollution, but also get rid of second-hand smoke.
This gas diversion trough is the aerodynamic device previously mentioned by Xiao Bian. It can send the filtered air directly to the people's nose and mouth in one step; and creates a film on the front to ensure that the air flow will not be blown directly. Face, make the face more gentle and comfortable.
The bottom of the purifier silicone mask is also reserved a lot of vents, the purpose is to promptly exhaust exhaled exhaust.
Contrast display
Introduced so many this DNC electric respirator, then it compared to the market above the ordinary pollution prevention mask, what are the outstanding advantages ? Here we are through the actual comparison analysis, the comparison of products including respiratory purifiers, cotton cloth Masks and 3M disposable masks.

Another protective mask in the form of a cotton cloth also contains a filter that can be replaced and placed inside. Xiao Bian after using several times feel the drawbacks of such masks lies in breathing difficulties, especially when worn in winter, the exhaled gas is easy to cover the above spectacle lenses; if you adjust the lanyard on both sides to tighten a little, there will be breathing Difficult situation. In contrast, DNC has a natural presence in the breathing because it exists on the motor side.
In the end, the comparison of the lanyards of the three masks is basically a design that has no special appearance, and thus replaces this traditional way of wearing. If you let the user wear a mask like a hat, there will be no discomfort.
Use display
In general, this breathing apparatus is simple to wear and very comfortable. It is a good choice for outdoor travel or to prevent pollen allergies and secondhand smoke.
From the side effect of wearing, it is very close to the mask and face. Xiaobian suggested that some cosmetic elements should be added on the surface of the mask, such as the cartoon elements suitable for children's wear; the trend elements suitable for young people to wear, etc. Make it look more stylish fashion effect.
Compared with the actual wearing effect of traditional protective masks and respiratory purifiers, everyone can clearly see the difference between the two.
About this DNC electric respirator evaluation posts, Xiao Bian brings so much to everyone, the article may say that there is no detailed or incomplete assessment of the place, but also please a lot of criticism and correction. In general, this product has spiked many similar products in the market due to its beautiful appearance and practical performance; however, Xiao Bian also found some deficiencies in the evaluation process. The summary is as follows. I hope the manufacturer can consider it. Xiaobian suggestions.
1. The lanyard design of the breathing purifier is recommended to be replaced by a more comfortable wearing solution.
2. The purifier lacks an air quality detection function module. It is recommended to add a mini display on the mask surface to remind the user of ambient air quality.
3, mask removal is more complex, minus the screw fixing method to a simple mechanical structure, allowing users to clean, replace the filter more convenient.
4, hope that the latter part can increase the mobile phone APP function, such as adding some social functions, so that this breathing purifier is also becoming smart.
