There are various air purifiers, car air purifiers, to solve the indoor air quality. So, what is the effect of car air purifier? What should you start with when buying?

1. CADR and purification energy efficiency of particulate matter, the higher the CADR value of particulate matter, the faster the purification rate. The higher the value of purification energy efficiency, it means that the product is energy-saving and the purification effect is better, which is an important indicator for purchasing car air purifier.

2. The CADR and purification energy efficiency of formaldehyde, TVOC and benzene. The higher the CADR value, the faster the purification of gaseous pollutants. The higher the purification energy efficiency (η) value, the stronger the purification ability.

3. The accuracy of the nominal value of the rated power. The input (or marked rated power) power of the purifier is small, which does not mean that its purification capacity is low. The purification capacity is mainly based on the clean air volume (CADR value) of the car air purifier.

4. The cost of later use, the key component of the car air purifier is the filter. The filter needs to be replaced regularly, otherwise it will become a source of air pollution and cause secondary pollution. Therefore, it is very important to replace the filter regularly.

You can consider buying a car air purifier from the above aspects. Here are a few tips about car air purifier, I hope it will be helpful to you.

1. Don't buy cheap car air purifier, which can't purify the air and may have a counterproductive effect;

2. It is possible to buy and use some big brands of car air purifier products with quality assurance, but these products cannot independently achieve the goal of purifying the air in the car. At the same time, the filter element of the car air purifier is very small, so the daily use will be scrapped quickly;

3. Under normal circumstances, the air-conditioning internal circulation mode can effectively and quickly reduce the PM2.5 pollution in the car;

4. It is necessary to pay attention to cleaning the car air purifier regularly and replacing the filter element;

5. The internal circulation cannot solve the pollution generated by the interior of the car, and the long-term lack of ventilation will also cause the carbon dioxide concentration in the car to increase. If you feel the air quality is not good, you can turn on the external circulation mode of the air conditioner for ventilation, and then switch back to the internal circulation to filter particulate pollutants.
