Vehicular air purifier, also called vehicular air purifier and automobile air purifier, refers to the air purification equipment dedicated to purify PM2.5, toxic and harmful gases (formaldehyde, benzene series, TVOC, etc.), peculiar smell, bacteria, viruses and other car pollution in the air of the car.
After the Industrial Revolution, heavy industry developed in many parts of the world, leading to plummeting air quality and serious threats to human health, including the famous "Los Angeles photochemical smog event". In order to improve air quality, in addition to the introduction of long-term air governance policies, many scientific research institutions are also actively developing air purification technology, in the first time to bring healthy breathing experience for consumers. Of course, none of this technology was originally used in cars. After a long period of concept transformation, when people realized that the air inside the car also has serious pollution, the on-board air purification technology specifically for cars gradually got attention.
Many countries have strict controls on the air quality inside cars. In this regard, On March 1, 2012, China also issued "Guidelines for Air Quality Evaluation in Passenger Cars", the release of which has played a great role in promoting the development of in-car air purification products in China. Not only domestic brands, many well-known foreign brands have also landed in the Chinese market.
When choosing a car air purifier
1. Pay attention to the standard value of particulate matter clean air quantity and purification energy efficiency of products, and choose products with higher values.
2. Attention should be paid to the clean air quantity of formaldehyde, TVOC, benzene and other pollutants of the product as well as the standard value of purification energy efficiency, and the product with higher value should be selected.
Understand the purification function of the filter
Tips:
The key component of vehicle air purifier is filter screen. The filter screen needs to be replaced regularly, otherwise it will become a source of air pollution and produce secondary pollution. Therefore, it is important to change the screen regularly.
The key to the purification effect of vehicular air purifier lies in its internal filter performance. The screen used in the vehicle air purifier is usually HEPA screen, activated carbon screen or composite screen.
1.HEPA filter is mainly aimed at particulate matter in the air, and achieves purification effect by filtering and intercepting particulate matter in the air.
2. Activated carbon filter mainly through the adsorption capacity of activated carbon, to achieve the adsorption of gaseous pollutants so as to achieve the purification effect.
3. The composite filter can not only purify particles, but also remove gaseous pollutants. From the comparative test, most of the products sold at present use composite filter.
When using
1. When using the car purifier, do not open the window and use internal air circulation.
2. When you do not need to use the car air purifier or do not drive for a long time, pay attention to unplug the power cord of the car air purifier.
3. Clean the filter screen regularly and replace the filter screen in time to ensure the purification effect.
4. The purification of the air in the car can not completely rely on the air purifier in the car. A variety of means should be used to solve the problem of air pollution in the car. In good weather, open the window ventilation is a very good way to purify the air inside the car.
After-sales service
1. Purchase should also understand the convenience of after-sales service. Include installation, complete machine warranty time (1 to 2 years have), product cleaning, filter cleaning, replacement and replacement filter cost, filter whether to buy convenient and so on.
