How Cabin Air Filters Work
Like an engine air filter, your 2011 Silverado air filter is made with layers of fabric or paper pleats. Between the layers is activated charcoal to neutralize odors and capture particles just a few microns in size. It's installed in an air duct inside the truck underneath the dash like a sentry for dust, pollen, mold, and any other allergens. The air that passes through the cabin filter is cleaner, smells fresh, and helps you stay healthier.
When to Replace an Air Filter
Cabin air filters collect debris, dust, and other contaminants and trap them in the folds. Eventually, it becomes restricted or damp and needs to be changed. If you notice a mildew smell, less airflow from the vents, or you can see there's debris in the filter on visual inspection, it's time to change it. A cabin filter for 2011 Silverado models should be changed at least once per year.
