Cabin Air Ionizer 

The Cabin Air Ionizer is a convenience technology that aims to provide higher air quality for drivers and occupants of its vehicles.

The purpose of the cabin air ionizer is to provide higher air quality in the vehicle compared to vehicles without the feature. Specifically, the feature delivers cleaner and fresher air, eliminates odors and provides higher air quality.  It helps address external and internal odors and reduce bacteria, viruses, dust, debris and pollen, while also helping improve driver alertness. 

The air ionizer works by producing negatively charged particles that attract air-borne contaminants and break down their structure, cleaning the cabin air.  The air ionizer requires no maintenance or filter replacement. 

This feature is now standard or available on most Buick models.
