Solve The Mystery: Why Is My Cabin Air Filter Making Noise?

When you turn on your car’s air conditioning or heating system, you expect to hear the gentle hum of the fan. But if you hear a loud rattling or whistling noise, it could be a sign that your cabin air filter is dirty or damaged.

A cabin air filter is a pleated paper filter that traps dust, pollen, and other airborne particles from entering your car’s interior. Over time, the filter can become clogged with debris, which can restrict airflow and cause the filter to make noise.

In addition to dirt and debris, a cabin air filter can also become damaged if it is not replaced regularly. A damaged filter can allow particles to bypass the filter and enter your car’s interior, which can cause respiratory problems for you and your passengers.
