Replacement Air Filter for Sub-Zero Refrigerators

When I shake the GLACIER FRESH Air Filter, why does it sound broken?

There is a small UV bulb within the air filter that helps to clean the air inside the refrigerator. When you shake the air filter, the charcoal inside may hit the light bulb, causing a sound that might make it seem like the device is broken. However, this is perfectly normal, and the unit is usually not actually damaged.
