What does cleanair mean in a car?

[SanGemma]

Cleanair in a car refers to the air purification function. When the driver turns on the internal or external circulation, this function automatically activates, filtering harmful gases to ensure clean air inside the vehicle. Cleanair generates plasma through a high-voltage circuit, which disrupts the protein membrane on the surface of bacteria with positive and negative ions, causing them to lose vitality and die, thereby eliminating bacteria in the air. The car air conditioning is a crucial comfort feature in a vehicle, capable of cooling and heating, as well as filtering out impurities from the outside air. If the air conditioning system is not cleaned for a long time, turning it on may produce an unpleasant odor. Therefore, it is important to clean and maintain the air conditioning system regularly.

The day I picked up my new car, I immediately noticed the CLEANAIR button on the center console. The salesperson told me this is the onboard air purification system. When activated, the car's fan will start running, filtering out dust, pollen, PM2.5 and other pollutants from the air through specially designed filters. Living in a northern city where haze is particularly severe during winter and spring seasons, I've noticed a significant improvement in air quality inside the car after using this feature. It's especially helpful when driving my parents around - elderly people with sensitive respiratory systems no longer need to wear masks in the car. The system can automatically detect air quality too. When stuck in traffic with heavy exhaust fumes, it automatically boosts its operation, which is really convenient.

Last time I took my daughter to the children's hospital, she kept coughing on the way back, so I turned on the CLEANAIR mode. This feature is mainly designed to improve in-cabin air quality, and its working principle is actually similar to that of a household air purifier. There's a small sensor on the roof that detects PM2.5 and harmful gases, and then the system automatically adjusts the air circulation between inside and outside. The most considerate part is that it releases negative ions to neutralize residual smoke or food odors in the car. It's especially suitable for parents like me who frequently shuttle kids to and from school, as children are less likely to develop allergies or sneeze in the enclosed space. Plus, it operates very quietly without affecting music playback.

I used to feel dizzy while driving, and later realized it was caused by the unpleasant odors inside the car. The salesperson suggested trying the CLEANAIR mode. As soon as I pressed the button, the dashboard displayed that the air purification was activated. The principle involves a three-layer filtration system: the primary filter traps large particles, the activated carbon layer absorbs odors, and the HEPA filter captures fine pollutants. Now, I always use this function when driving, especially after refueling during long trips when there's a gasoline smell inside the car. It only takes about two minutes to restore fresh air.
