"Clean" + "air" means purifying the air. Here is a detailed introduction about Volkswagen CleanAir: 1. Function of Volkswagen CleanAir: When the driver turns on the internal or external circulation, the CleanAir function will automatically activate. As an air purification function, it naturally filters harmful gases to ensure clean air inside the vehicle. 2. Principle of CleanAir air purification: Air conditioning filter with activated carbon. An additional activated carbon layer can adsorb more harmful substances onto the filter, although the price of this filter is several times higher than that of a regular one. Negative ion air purification. High-voltage circuits generate plasma, which disrupts the protein membrane on the surface of bacteria, causing them to lose vitality and die, thereby eliminating bacteria in the air.
