This is the Wix Filters 24780 Cabin Air Filter, a cabin air panel filter designed to be a direct-fit replacement (OE replacement) in specific GM vehicles. It captures airborne contaminants such as dust, pollen, soot, and provides enhanced protection against musty odors via activated carbon media. The filter combats the ingress of leaves, bugs, dirt and other debris that negatively affect the HVAC system’s heater, air conditioner and defroster functions.
The construction features a panel style filter media that is of the particulate type with activated carbon additive for odor reduction. The media is enhanced with Microban® antimicrobial technology to inhibit growth of odor-causing bacteria and mold on the filter surface. Dimensions are precisely confirmed as 11.28 inches (length) × 7.19 inches (width) × 1.19 inches (height).
In real-world use this filter is intended for light-duty service to maintain clean air inside the cabin, improve HVAC performance and reduce allergens and odors. It’s ideal replacement for drivers seeking better odor control and air quality in compatible Buick, Chevrolet, Oldsmobile and Pontiac models during normal and severe driving conditions.
