New concept of health, vehicle air purifier
With the improvement of the quality of life, more and more friends pay attention to the health problems in the car.
We all know that the on-board air purifier can purify the air in the car. However, it is difficult to buy the on-board air purifier. There are many brands of on-board air purifiers on the market, with complex models and prices ranging from hundreds to thousands. How to choose?
How to choose a good on-board air purifier? In short, you can look at the parameters, the efficacy and the certification.
1. Cadr is the key performance parameter of on-board air purifier, which refers to the amount of clean air per unit time, which is divided into the Cadr value of particulate pollutants and the Cadr value of gaseous pollutants.
We are familiar with PM2 5. Dust and smoke belong to particulate pollutants, formaldehyde and benzene belong to gaseous pollutants. The larger the Cadr value, the stronger the purification ability in this field.
2. General air pollution is divided into PM2 5 as the representative of particulate pollutants and gaseous pollutants represented by formaldehyde. Whether an on-board air purifier is effective depends on whether it can effectively filter a variety of pollutants.
3. An excellent on-board air purifier generally needs to be tested and certified by a third-party organization, which also shows the quality of the product. At the same time, the product removes PM2 5. The purification ability of bacteria, viruses and nicotine has also passed the test of a third-party authority.
