How To Recognize A Problem With Your Car’s Air Filters

There are many benefits to replacing your air filter. It’s essential to be aware of the warning signs when a filter is ready to be changed.

Most modern cars are equipped with 2 distinct air filters – the cabin air filter and the engine air intake filter.

The Cabin Air Filter

If your car holds a cabin air filter, changing it regularly can improve the your AC system’s performance. The cabin air filter eliminates allergens, pollen, bacteria and mold spores from the air. While doing so, it accumulates waste and eventually clogs with debris. This can cause issues with the heater and air conditioner.

If you observe ventilation issues and call an amateur auto mechanic who neglects the air filtration system, they could mistakenly diagnose a compromised AC or cooling system. You could pay the price for unnecessary repairs.

A few signs your car is ready for a cabin filter change:

  • It’s been more than a year since your air filter was last checked
  • A dirty or musty smell is coming from the air vents
  • You notice heating or cooling inefficiencies
  • You’re experiencing breathing problems, headaches or allergic reactions while driving

The Engine Air Intake Filter

A dirty cabin filter affects the AC system’s efficiency, but an old engine air filter can reduce the car’s acceleration power and decrease fuel economy. As the intake filter accumulates airborne debris, bug bits, tree sap and other pollutants, airflow to the engine is reduced.

Restricted airflow forces the engine to work harder, hindering acceleration power and wasting fuel. In fact, according to the Car Care Council, changing an obstructed engine air filter could improve gas mileage by as much as 10%.

A few signs your car needs an engine air intake filter replacement:

  • It’s been 10,000-30,000 miles since your last filter check
  • You regularly drive down dusty rural roads or streets with heavy construction
  • You’ve observed a loss in engine power
  • You experience hesitation during acceleration
