Billowy CF11966 Cabin Air Filter with Nutshell Activated Carbon – Fits Chevy/GMC/Buick/Cadillac 2016-2025

Experience cleaner cabin air with Billowy CF11966

The Billowy CF11966 Cabin Air Filter with Nutshell Activated Carbon combines a melt blown electrostatic layer, a HEPA-like filter, and a carbon core to help keep cabin air fresher. It is designed to trap fine dust, pollen, and everyday odors so that you can enjoy a more comfortable ride, whether you're commuting, running errands, or hitting the highway.

Strong filtration, built to last

A high-density electrostatic electret layer works with a honeycomb design to maximize the filtration area. The Nutshell activated carbon layer targets odors and VOCs, supporting longer service life and stable airflow between replacements.

In real-world driving, you may notice fewer dust settles on surfaces and a more even climate control feel, especially on dusty roads or during pollen season. Odors from city traffic or cooking odors can be moderated, contributing to a more pleasant cabin experience.

Built for a broad range of models

The CF11966 is compatible with many Chevrolet, GMC, Buick, and Cadillac models from 2016 to 2025. Examples include Silverado 1500/2500 HD, Equinox, Malibu, Tahoe, Suburban, Traverse; GMC Acadia, Canyon, Sierra; Buick Enclave, Envision; Cadillac Escalade, XT series, XTS; and more. Please enter your year, brand, and model to confirm compatibility before purchasing to ensure a proper fit.
