Most vehicles have two air filters: one for the engine and one for the cabin. They both capture pollutants before they can make their way into either the engine parts or the HVAC system.

What Air Filters Do

The engine air filter sits near the air intake, where it traps contaminants and dirt before they get into the motor.

The cabin air filter is typically found behind the glove compartment or under the front cowling. It collects irritants and allergens before they can make their way through the air vents and foul the cabin atmosphere.

Unfortunately, those air filters will either eventually get clogged up by the pollutants or begin to degrade. When that happens, your engine performance will begin to suffer, and HVAC trouble can occur.

How to Identify Failing Air Filters

Signs of problems include:

Your engine misfires
The "Check Engine" dash light comes on
You begin to lose horsepower
You notice dark smoke coming from the exhaust
You have difficulty maintaining a consistent cabin temperature
You hear whistling sounds coming from the air vents
