Protect Your Engine's Lungs - The Importance of Air & Cabin Filters
Like you, your car breathes. To keep everything functioning properly, your car's filters must remain clean, just like your lungs. Despite being tiny, low-cost components, air and cabin filters have a significant impact on the comfort, efficiency, and performance of your car.
What Are the Functions of the Cabin and Air Filters?
In reality, your car has two primary filters that aid in its "breathing":
- By removing dust, grime, and debris that could harm internal parts, an engine air filter purifies the air that enters your engine.
- A cabin air filter helps you and your passengers breathe cleaner air by filtering the air that enters your car through the ventilation system and capturing pollutants, pollen, and odors.
- Both filters—one for you and one for your car—protect critical systems in the background.
Why Clean Filters Matter
- Better Performance & Fuel Efficiency
A clogged air filter restricts airflow to your engine, forcing it to work harder and burn more fuel. Replacing it regularly helps your engine breathe freely, improving power and gas mileage. - Cleaner Air Inside Your Vehicle
Your cabin filter traps dust, allergens, and exhaust fumes before they enter your car. A clean filter means cleaner, fresher air — especially important for anyone with allergies or asthma. - Longer Engine Life
Dirt is one of an engine’s worst enemies. The air filter keeps abrasive particles from entering the combustion chamber, preventing wear and tear that can lead to expensive repairs. - Odor Control & Comfort
If your A/C smells musty or the air feels stale, it’s probably time to replace the cabin filter. A new one helps eliminate odors and restores proper airflow through your HVAC system.
How Often Should You Replace Them?
Although it can vary based on your driving circumstances, most air and cabin filters should be changed every 12,000 to 15,000 miles. You might need to change them more frequently if you drive through construction zones, in dusty areas, or in areas with high traffic.
Common signs your filters may need attention include:
- Reduced airflow from your vents
- Musty or unpleasant odors inside the car
- Decreased fuel efficiency
- Hesitation or sluggish acceleration
Quick Tip
Ask your technician to check both filters at each oil change, and consult your owner's manual for the recommended replacement interval. It's among the simplest and least expensive ways to safeguard both your comfort and the functionality of your car.
