Do your nostrils itch whenever you turn on your car’s A/C? Does your cabin have this moldy smell even with air fresheners? Then you probably need to change cabin air filter.

A clogged air filter not only lowers the quality of air in your cabin; it can also bust the A/C blower. So be sure to regularly clean or replace your cabin air filter every year or every 12,000-15,000 miles.

Changing cabin air filter is so easy you can do it in less than an hour. For a guide on how to change cabin air filter, watch the video below.
