But the system is the same as, for example, a sponge: The Recording capacity is not infinite. This creates the following problem: On the surface of the filter the most dirt If this with moisture through the air from outside, which promotes the formation of microorganisms. Germs spread inside the vehicle and switching on the air conditioning ensures that Mould fungi release their spores indoors.

Why clean the vaporizer regularly?

The more dirt the filter catches, the Logically, the filter effect is less strong and small particles can slip through the filter. The particles are then passed on to the evaporator, especially when the air conditioning is running.

The Evaporator is comparable in structure to a cooler and has small slats. Through the “condensation processes”, such as the ADAC writes, the evaporator surface is usually moist. In combination with the dirt particles, the moist air provides the perfect Breeding ground for microorganisms.

The interior of your car is small. Therefore, even a small concentration of dirt particles is enough to make the air in your car harmful. This can be made even worse by the recirculation mode.
