When buying

1. Pay attention to the marked value of the product's particulate clean air volume and purification energy efficiency, and choose a product with a higher value.

2. Attention should be paid to the clean air volume and the marked values of purification energy efficiency of pollutants such as formaldehyde, TVOC and benzene, and products with higher values should be selected.

Understand the purification function of the filter

Tips: The key to the purification effect of the car air purifier is the performance of its internal filter. The filters used in car air purifiers usually include HEPA filters, activated carbon filters or composite filters.

1. The HEPA filter is mainly aimed at the particulate matter in the air, through filtering and intercepting the particulate matter in the air to achieve a purification effect.

2. Activated carbon filter mainly achieves the adsorption of gaseous pollutants through the adsorption capacity of activated carbon to achieve the purification effect.

3. The composite filter can not only purify particulate matter, but also remove gaseous pollutants. From the comparison test, most of the products currently sold use composite filters.

when using it

1. When using a vehicle-mounted purifier, do not open the window and use the internal air circulation.

2. When you do not need to use the car air purifier or when you are not driving for a long time, please pay attention to unplug the power cord of the car air purifier.

3. Clean the filter regularly and replace the filter in time to ensure the purification effect.

4. The air purification in the car cannot be completely dependent on the car air purifier. To solve the problem of air pollution in the car, a variety of methods are required. In good weather, opening windows for ventilation is a very good way to purify the air inside the car.
