“Why do mechanics always ask about replacing the air filter but not usually the cabin air filter?” This question from a viewer is a good one.

Many mechanics also aren’t aware of the cabin air filter’s replacement intervals or those intervals may be so far apart that many people don’t actually remember when the filter was swapped last. I’ll answer those questions and more here.
