Toyota uses a cabin air filtration system to remove pollen, dust and debris from the air, before it enters the passenger compartment of 2001 Highlander. The keystone of this system is the cabin air filter. Located behind the glove box, the filter traps a wide variety of airborne debris before it makes its way in to the ductwork that feeds the interior vents. Toyota recommends replacing this filter every 30,000 miles, but it's best to inspect it more often and replace when you can no longer see light shining through it.
