What does cleanair mean and what button is it on the car?

[MacDaisy]

The cleanair in a car refers to air purification, which is a function within the vehicle's air conditioning system. The car air conditioner is a crucial comfort feature in automobiles, capable of cooling, heating, and filtering out impurities from the external air. More relevant information is as follows: 1. Air Filter: Most air conditioning systems are equipped with a filter that requires regular replacement. If the air quality in your area is poor, you can purchase a filter capable of filtering PM2.5 to ensure the health of the vehicle's occupants. The air conditioning system also needs regular cleaning and disinfection after prolonged use. If not cleaned, the system can harbor numerous bacteria, which may affect the health of the car owner. 2. Note: If the air conditioning system is not cleaned for a long time, there may be an unpleasant odor when the air conditioner is turned on. When cleaning the air conditioning system, it is advisable to use high-quality cleaning agents, as inferior ones may damage the blower motor bearings, leading to noise during operation.
