While many drivers know their vehicle contains an engine air intake filter, few realize their car likely holds a second air filter – the cabin air filter.

Cabin Air Filter

While rarely discussed, the cabin air filter can have a significant affect on your car’s ability to perform. The cabin filter, which typically sits right in front of the HVAC system, gradually accumulates dirt and debris. When the filter becomes too dirty, it can hinder the air conditioner and heater’s performance.

If you recognize ventilation problems and bring your car into an inexperienced auto mechanic, you could end up paying the cost of unnecessary AC system repairs.

Remember: always replace a soiled air filter. Don’t simply clean the filter and re-install.

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

Engine Air Intake Filter

While a dirty cabin air filter can damage the AC system, a dirty engine air filter can cause engine performance problems. As your car drives down the road, it’s sucking in airborne contaminants and shrapnel. These bits of debris can clog the engine filter, reducing airflow to the engine. When this happens, the dirty filter robs your engine of power.

A reduction in clean oxygen affects the fuel-to-air ratio, causing unnecessary strain on the engine. This impedes fuel efficiency and can cause a loss in acceleration power.

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

To keep your car operating at maximum efficiency, we suggest an air filter check every 3,000-6,000 miles. Regular checkups ensure both the cabin air filter and engine air intake filters are free of debris.

A visual inspection is free of charge, and evaluations keep the filters from hindering vehicle performance. And rest assured – we personally guarantee our ASE-certified technicians never suggest a replacement or repair unless it is absolutely necessary.
