Increased haze days, air-conditioning filters need to be replaced twice a year is appropriate


This winter, a wider range of haze attacks the country, and more and more people are accustomed to wearing masks while driving. They also need “masks”—that is, air-conditioning filters—to reduce the concentration of particulates in cars. Vehicle maintenance experts, usually owners are only in the car care when replacing the air filter, but with the increase in haze and dust, it is recommended that owners regularly replace the air filter, a year is best to replace twice Filter.

Air conditioning filter manufacturer MANN+HUMMEL introduced the test results show that if there is no air conditioning filter, the concentration of pollutants inhaled by the driver is much higher than the pedestrians on the road, just like the vacuum cleaner, the air inhaled by the vehicle ventilation system. Contains contaminated particles and harmful gases, and up to 420,000 liters of air per hour enter the interior of the vehicle through filters, air conditioners, heating systems, and bellows. The developer of the MANN brand filter introduced that, as time goes by, the filter core will become gradually blocked, and the capacity of the bellows will be reduced by 50% to 70%. In order to ensure completely effective air filtration and good ventilation, air-conditioning filters should be replaced on a timely and regular basis. Therefore, regular replacement of filters is a necessary health investment for drivers who often drive or run for long distances.
