General

Air ionization makes it possible to refresh and clean the air in the vehicle interior. Interior air ionization is odorless, as such vehicle occupants cannot directly perceive it. Ionizers are controlled by control of the climate control.

Location

The ionizer is located on the air duct leading to the driver side air vent.

Function requirements

Climate control switched on
Ionization active
Blower switched on

Function

The ionizer is dust binding. This effect is based on the fact that charged ions attach to dust particles in the air. As a result of their electrostatic interaction, they encourage integration with other particles to form a larger cluster. The ionizer then filters this cluster more easily than individual particles.
