The cluster ionizer helps clean odor in the vehicle or from the air-conditioner system.

When the ignition switch is ON, the inoizer runs a "CLEAN" mode and then a "ION" mode, switching between both modes.

In the “CLEAN” mode, the cluster ionizer generates negative and positive ions to help clean smells from the air

In the "ION" mode, the cluster generates negative ions and cleans inside air of a vehicle.
