By the end of 2015, the number of private cars in China had reached 0.172 billion, and the number of private cars in 40 cities across the country exceeded one million, of which 11 cities including Beijing, Shanghai, Chengdu and Shenzhen had a private car ownership rate of more than two million. It can be said that private cars have become one of the necessary means of transportation for people to travel today.

Because the interior space is a relatively closed space, it is very easy to produce some air pollution problems that are difficult to detect, such as toxic and harmful gas pollution, microbial pollution and so on. Although these air pollution problems are not easy to be detected, they are far more harmful to human health than PM2.5 pollution. In order to solve the problem of air pollution in the car, people have invented an air purifier suitable for the car.

At present, there are more than 800 car air purifiers on the Chinese market, and at least 300 brands are producing car air purifiers. The mainstream air purifier brands have car products. For example, the internationally renowned brand Agcen has a net bully X series air purifier dedicated to the car.

Although the principle of car air purifiers is basically the same as that of home air purifiers, the purification environment is also different due to the different causes of air pollution in the car and indoor air pollution. Therefore, the new national standard for air purifiers with indoor air purifiers as the main service objects is not applicable to the car air purifier market. So, what if you buy a car air purifier? We recommend starting from six aspects.

First, safety performance. Safety is the primary consideration for car air purifiers. Because when the car is running at high speed, any items installed in the space of the car may endanger the safety of drivers and passengers. Therefore, the air purifier in the car must be installed firmly to ensure that the safety of the people in the car will not be affected in an emergency.

Second, it is easy to install. The car is a whole product, and various safety related factors have been referenced during the design. Therefore, the car air purifier must consider whether the installation is convenient, and achieve the result of not damaging the interior decoration under the premise of ensuring performance.

Third, power design. Limited to the power supply energy in the car, the energy consumption of the car air purifier must be kept at a low level, so as not to affect the normal operation of the vehicle.

Fourth, the shape volume. The space in the car is generally narrow, which also limits the size of the car air purifier. If the volume is too large, it is easy to cause inconvenience to the activities of the people in the car.

Fifth, design. The car is a medium and high-end product, so the appearance of the air purifier in the car should not be too cheap, otherwise it will destroy the overall decoration environment in the car.

Sixth, manufacturing materials. Due to the lightweight requirements of automobiles, the weight of materials entering the car should be reduced as much as possible, so the car air purifier should also pay attention to its own weight control and try to choose products with lightweight materials. At the same time, the environment in the car often has a large temperature difference, which also needs to be considered.
