What does clean-air mean in a car?
2 Answers
The display of clean-air in a car refers to air purification, which is a function within the car's air conditioning system. More related information is as follows: 1. The car air conditioner is a very important comfort feature in a vehicle. It can cool and heat, as well as filter out impurities from the outside air. The clean-air function in cars is an air purification feature, typically found in mid-to-high-end vehicles. Moreover, the clean-air button is merely an indicator and cannot be manually pressed. 2. Clean-air can adsorb more harmful substances onto the filter element through negative ion air purification. By generating plasma via a high-voltage circuit, the protein membrane on the surface of bacteria is destroyed by positive and negative ions, causing them to lose vitality and die, thereby achieving the goal of eliminating bacteria in the air.
The Clean-air button we press while driving is actually the air purification mode. This function activates the purification device in the air conditioning system, blocking external impurities like pollen and dust from entering the car. I always turn it on during smoggy days or when passing through construction sites, and the air inside the car becomes noticeably fresher. Some high-end models even include a negative ion generator, so you won't feel stuffy no matter how long you drive. However, it's important to note that this function mainly relies on the filtering effect of the air conditioning filter, so regular inspection and maintenance are necessary. Especially during pollen season in spring or for families with children, using this feature can make the ride much more comfortable.
