how often should a auto cabin filter be
When to replace. Potter says replace the cabin air filter every 15,000 to 25,000 miles, or once a year. Roberts recommends replacement every 30,000 miles, but adds drivers should check their ownerâs manual first. Changing a cabin air filter is a do-it-yourself project, but it may be difficult to remove, Potter says. âYou have to remove the glove box to access it,â he says.
