In the past, car air filters needed to be changed every 3,000 miles. Luckily, present-day air filters are made to work better and perform longer. In some cases (under the right driving conditions), your air filters can last up to 2 years! Even with high-performing filters, frequent 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 present-day cars contain 2 distinct air filters – the cabin air filter and the engine air intake filter.
The Cabin Air Filter
If your car is equipped with a cabin air filter, periodic replacements can greatly improve the performance of your AC system. Asthe cabin air filter sifts out allergens, pollen, bacteria and mold spores from the air, it accumulates waste. Gradually, the filter clogs with debris. This can cause problems with the heater and air conditioner.
If you notice heating or cooling issues and take your car to an inexperienced auto mechanic, you could end up paying for unnecessary repairs. A mechanic who fails to check the air filtration system could improperly diagnose an AC or cooling system malfunction.
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
An old or congested 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, the engine does not receive adequate airflow.
Restricted 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 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
