Ionization, Basic Function - GF83.80-P-9901A

Model all (CAR) 

with code P21 (Air quality package) 

Overview 

This document contains information on:

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 (1) is located on the air duct leading to the driver's side air vent.

Function 

The ionizer (1) binds dust. 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 (1) then filters this cluster more easily than individual particles.
