Climate control air filter
The climate control air filter installed behind the glove box filters the dust or other pollutants that come into the vehicle from the outside through the heating and air conditioning system.

A: Outside air
B: Recirculated air
C: Climate control air filter
D: Blower
E: Evaporator core
F: Heater core
If dust or other pollutants accumulate in the filter over time, air flow from the air vents may decrease. This leads to moisture accumulating on the inside of the windshield even when the outside (fresh) air position is selected. Have the climate control air filter replaced by an authorized Kia dealer.

-
Replace the filter according to the Maintenance Schedule. If the vehicle is being driven in severe conditions such as dusty or rough roads, more frequent air conditioner filter inspections and changes are required.

When the air flow rate suddenly decreases, have the system checked by an authorized Kia dealer.
