[PConline Professional Evaluation] Recently, the Ministry of Environmental Protection has proposed that the analysis of PM2.5 sources in 9 cities currently shows that the primary source of pollution is motor vehicles. In some urban roads, there is a serious blockage. During the traffic jam, the car can not be extinguished, which leads to a continuous decrease in fuel efficiency and a significant increase in the emissions of motor vehicles. This is probably the source of air pollution. Exposed to the human body, the quality of the breathing air is already very poor, and the exhaust gas generated by the car will bring serious health threats to drivers and occupants.
The air in the car not only has PM2.5, but it will volatilize itself, such as TVOC, formaldehyde, toluene and other hazards will cause chronic suicide. Therefore, Xiaobian recommends that vehicle air purifier be considered. This time came to the evaluation room is the lung lung car insurance launched by Yuanda Kongpin Technology Co., Ltd. It is a large portable mini purifier.
Product appearance and details
Grand Air Products launched the car with lung protection, packaging box with kraft carton packaging, the center is the car with lung protection product appearance picture, the overall simple and generous, but also gives a mysterious and noble feeling. The back of the box indicates the various parameters of the car air purifier, removal of PM2.5, accessories included, etc.
The box uses a snap-in design. The front is a body-mounted lung treasure body. On the left hand side is a car cigarette lighter connector and a USB cable. A quick start guide is provided to help users quickly grasp the usage of this car air purifier.
Using a white square body appearance, the simple design is the current mainstream style. The use of a honeycomb design at the top air inlet increases the amount of air entering the wind surface and at the same time ensures the high strength of the fuselage surface.
The side of the fuselage is a clean air outlet through which clean air can be delivered to the vehicle/indoor. The fuselage has only one button, it can control the high-low third gear and switch of the car lung treasure. There are light tips on the buttons, but this light is hardly noticeable in the sun. It is probably convenient for users to use at night.
To meet the needs of the car, equipped with car cigarette lighter connector and power cord. At the same time, non-slip mats are also provided to ensure that the car air purifier does not slide down due to steering etc. during driving.
Summary: As a whole, the vast empty product car lung insurance, the use of a white square body appearance, simple design is the current mainstream style. The use of a honeycomb design at the top air inlet increases the amount of air that passes through the air inlet. Simple one-touch operation allows users to easily grasp.
Purifier filter system dismantling
Broad Air Products This car lung car air purifier uses HEPA filter construction. Contaminated air is sucked from the top of the fuselage through a fan, filtered through the HEPA filter to pollute the air, and then through the side air outlet to output clean air.
According to reports, this fan has been specially designed. Its maximum noise is 52dB, and in the low-range case, 28dB does not affect the quality of sleep.
It uses a HEPA filter like an ordinary household air purifier and uses an organ folding design. It intercepts airborne dust, bacteria, viruses, germs, smoke and other 0.3-micron-sized pollutants, and the interception rate reaches 99%. This filter is not washable.
This car air purifier uses a powerful fan, which speeds up the flow of indoor air, adsorbs particulate matter in the air, filters it into the HEPA filter, and outputs clean air. What is its true purification effect? Please see our purification test below.
Purification capacity test
The purifying effect of the RV is the key to determining the quality of the air purifier on board. This time we chose to test it in the car. Close all the doors and windows, light a cigarette in the car to make it fully burned, and let the secondhand smoke fill the entire car. Using the tester to test the PM2.5 index in the air, the indoor PM2.5 was detected every 10 minutes, and the purification effect of the car air purifier was detected at different times.
After 10 minutes of purification, Xiao Bian was also surprised by the purification effect of this car air purifier, because once again tested, the indoor 0.5-micron particles have been purified most of the air quality has become better, while the smoke has dissipated.
Summary: It can be seen from the test that the vast empty product car lung car air purifier, about ten minutes, the use of HEPA filter can quickly clean the air pollutants. The purification effect also shocked Xiao Bian. The purification effect was quite rapid.
Airflow and noise tests
Air volume test
Next, we will test the wind speed and use the three wind speeds respectively. The wind speed is an important factor in determining the CADR of the purifier. CADR is one of the metrics of purification ability. It can quickly recirculate the air inside the car and output clean air. The vast empty product this car air purifier, using the top of the air, side of the wind design, more suitable for the needs of the car.
Locomotive air volume test for lofty air cargo vehicles
Low speed wind 1.43m/s Middle speed wind 2.89m/s 
High-end wind speed 6.04m/s Noise test
Many consumers want their products to be as silent as possible, especially when driving. Both can filter without affecting mood. This time we also chose three gears to test. Because of the limited testing environment and the lack of soundproofing, we tested it in a 43dB vehicle environment.
Great Air Vehicles' Lung Safety Noise Test
Low-range noise 46.7dB(A) Mid-range noise 54.1dB(A) 
High-end noise 69.1dB(A) Summary: Broad Air Products This vehicle uses the air to protect the air purifier fan set output moderate, while the low-end position has a quiet design, in the noise test purification effect, especially in the silent mode basically did not feel the machine makes noise, but in The noise under the high grade is a little bit too big and it is not suitable for long-term opening.
This mobile lung is more efficient than ordinary masks, filtering PM2.5, and at the same time providing a positive air supply to make the user breathe more smoothly. And this mobile lung with HEPA filter can eliminate the virus and prevent the pollution of the air.
Full text summary: Simple body design, pure white body shape. The use of the upper side of the intake air outlet method is more convenient for the purification of the vehicle. The most surprising to Xiao Bian is its purifier capability. From the test, it can be seen that it takes only 10 minutes to filter the particulates caused by the smoke inside the car. It is definitely the first choice for home-use car air purifiers. . When you go out, you can use mobile lung insurance instead of ordinary masks to achieve more comprehensive protection.
