Is it not necessary to replace the air conditioner filter in winter?

Under normal circumstances, the maintenance cycle of a vehicle's air conditioning filter is about once every half a year, and it is best to add an extra maintenance every time the seasons change. Take autumn maintenance as an example. After summer, when using air conditioners, unpleasant odors are likely to occur. At this time, the air conditioner filter needs to be replaced to ensure that the warm air in winter is not affected. The air conditioner filter is like the lungs of a person. When you turn on the external circulation of the air conditioner, the air conditioner filter can block the invisible fine particles in the air, such as dust and dirt, as well as various unpleasant odors. Ensure that the air entering the vehicle is clean. If the air conditioning filter is very dirty and its filtering function disappears, these invisible bacteria and fine dust will be blown into the car through the air conditioning air and sucked into the lungs.

Many car owners believe that air conditioners are only used in summer and it is sufficient to clean them in advance. In fact, it is not the case. When using warm air in winter, it also needs to be purified through the air conditioning filter. If car owners use their vehicles frequently, they can replace it once before winter comes. If you feel that the cooling effect is poor during daily use or if the vehicle model lacks an air conditioning filter, try to use the internal circulation as much as possible to reduce the entry of dirty air.

Winter is a season when smoggy weather occurs frequently. In the just-passed October, smog in the central and eastern parts of China showed a high incidence. Among them, Heilongjiang, Liaoning, Hebei, Shandong, Shanxi, Henan, Anhui, Hunan, Hubei, Zhejiang, Jiangsu, Chongqing and Tianjin had the most smoggy weather in the same period of history. The PM2.5 index seriously exceeded the standard, and smoggy weather caused great damage to the lungs. If not prevented, it is easy to induce bronchial, respiratory tract and lung diseases, etc.

The function of the air conditioning filter element is to prevent haze in the air from entering the air conditioning system. As a result, moisture and dust will remain on the filter element, which is very likely to breed bacteria. After starting the air conditioner, it not only affects the intake air volume but also causes pollution to the fan and pipes, leading to a series of problems. Therefore, in winter, never forget to replace the air conditioning filter.
