More about Passenger Cabin Air Filters
The passenger cabin air filter removes contaminants from the air that is circulated by your car's heater and air conditioning system, as well as the air that those systems draw into your car. Passenger cabin air filters were first used on luxury cars in the late 1980s, but are now found on many vehicles. If the passenger cabin air filter becomes clogged with contaminants, your heater, air conditioning system and defroster may not operate at full strength, and window condensation could become a problem. Even if no problems are evident, most experts recommend replacement of the passenger cabin air filter once a year or every 12,000 miles.
