Chevrolet Cabin Air Filter Buyer's Guide

Most cars have a cabin air filter to keep the air clean inside the cabin. Some older cars do not have cabin air filters, and that is why they always seem dustier than new cars. If your GM has a cabin air filter, it pays to know when and how to replace it. That's what this guide is for.

In this guide, you'll learn all about cabin air filters and how to install them.

What's a Cabin Air Filter?

It's important to change your cabin air filter every 12,000 miles (give or take) or once a year. It's to keep the air inside the cabin as clean as possible. A cabin air filter is a square or rectangular pleated filter that serves as a barrier between the car's HVAC system and the cabin. It filters the air that comes in from outside of the vehicle before the air makes it into the cabin.

Checking Your Cabin Air Filter

It's important to replace your cabin air filter as soon as it becomes dirty in order to keep the air inside the cabin clean (especially during allergy season) and to keep the blower motor in good shape. A dirty cabin air filter will wear out the blower motor faster, and replacing a blower motor is not the most rewarding job.

If you're not sure if your cabin air filter needs to be replaced yet, you can take it out and visually inspect it. It's a pretty easy task because cabin air filters are readily accessible. This tutorial will walk you through the process: How to Diagnose a Failing Cabin Air Filter
