How To Recognize Air Filter Problems

Drive clean with cabin air filter and engine air intake filter replacements

In the past, auto mechanics knew car air filters needed to be replaced every 3,000 miles. Fortunately, present-day air filters are made to perform better and last longer. In most cases (and under the right driving conditions), your air filters can last up to 2 years! Even with longer-lasting filters, periodic checks will let you know when they need to be replaced.

There are many benefits to air filter replacements and it’s important to recognize the warning signs of a filter ready to be changed.

Most modern cars contain 2 distinct air filters – the cabin air filter and the engine air intake filter.

The Cabin Air Filter

If your car has a cabin air filter, regular replacements can greatly improve the performance of your AC system. Asthe cabin air filter eliminates allergens, pollen, bacteria and mold spores from the air, it accumulates waste. Over time, the filter clogs with debris. This can cause problems with the heater and air conditioner.

If you notice ventilation issues and take your car to an inexperienced auto mechanic who fails to check the air filtration system, they could mistakenly diagnose an AC or cooling system malfunction. An improper diagnosis could end up costing you in 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 inspected
  • You notice a dirty or musty smell from the air vents
  • You’ve observed heating or cooling inefficiencies
  • You’re experiencing breathing problems, headaches or allergic reactions while driving

The Engine Air Intake Filter

A dirty cabin filter hinders the AC system’s performance, but a dirty engine air filter can cause acceleration problems and decrease fuel economy. As the intake filter clogs with airborne debris, bug bits, tree sap and other pollutants, airflow to the engine is restricted.

A decrease in airflow forces the engine to work harder, impacting acceleration power and wasting fuel. In fact, according to the Car Care Council, replacing an old 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 inspection
  • You frequently drive down dusty rural roads or streets with heavy construction
  • You’ve noticed a loss in engine power
  • You experience hesitation during acceleration
