How to use Volkswagen's clean-air?
2 Answers
The usage method of Volkswagen's clean-air is: The clean-air in the car is an air purification function. When the owner turns on the internal or external circulation, the clean-air function will automatically activate. Its purpose is to filter harmful gases and ensure clean air inside the car. The details on how Clean-air achieves air purification are as follows: 1. Air conditioning filter with activated carbon. An additional activated carbon layer can adsorb more harmful substances on the filter. Of course, the price of this air conditioning filter is several times higher than that of a regular one. 2. Negative ion air purification. High-voltage circuits generate plasma, which destroys the protein membrane on the surface of bacteria, causing them to lose vitality and die, thereby eliminating bacteria in the air.
Last time I drove my friend's Volkswagen Tiguan L, I specifically tried out this Clean Air function. You just need to find the 'Air Purification' icon on the central control screen and tap it, and the screen will display the real-time PM2.5 level inside the car. I found that it's best to open the windows for half a minute to ventilate before activating it, and once the value drops, it automatically switches to internal circulation. It's especially effective on rainy days, as it can remove the musty smell that causes fogging on the windows. Pay attention to the filter maintenance indicator light—my friend said he replaces the filter at the dealership every 8,000 kilometers, and after three years of use, the air conditioning still doesn't have any odors. On long trips, using it with seat ventilation makes the ride even more comfortable, but if someone smokes in the car, you'll need to manually increase the fan speed.
