All 2011-up Grand Cherokee vehicles come standard with a particulate air filter that helps purify the outside air entering the HVAC housing. The filter is mounted in the passenger compartment, behind the glove box bin.
The filter should be replaced at least once a year or every 15,000 miles (24,000 km) and checked if heating-A/C system performance seems lower than expected. The particulate air filter is labeled with an arrow to indicate the direction of air flow through the filter.
Regularly changing cabin air filters also can reduce build-up of debris and bacteria on the evaporator core of your car’s air conditioning and ventilation system, maximizing the life of the system. Cabin air filters stop most airborne particles, and to some extent are capable of reducing mild odors.
