Fortunately, modern air filter manufacturing has produced air filters that achieve more and stay clean longer. Most present-day air filters can last at least 10,000 miles and many can be used as long as 30,000 miles.

However, your 2 air filters – the cabin air filter and the engine air intake filter – still need to be replaced periodically. In fact, regularly changing your air filters can drastically improve your car’s ability to perform.

Here are the 4 biggest benefits to replacing your vehicle’s air filters:

1. Protect your AC system

When your cabin air filter is worn and clogged, accumulated debris can build up on the AC system. This waste can restrict airflow to the air conditioner and heater, hindering performance. According to Rich White, executive director for the Car Care Council. “Checking the cabin air filter is a simple preventive maintenance step that goes a long way toward protecting passengers, as well as the vehicle’s HVAC system.”

2. Avoid unnecessary repair costs

When a dirty air filter obstructs airflow to the ventilation system, an amateur auto mechanic may mistake the issue for an air conditioning or heating problem. If your car is brought into an auto repair shop who inspects the AC system or cooling system without first evaluating the cabin air filter, you could end up being charged for unnecessary repairs. At Christian Brothers Automotive Montgomery, our ASE-certified technicians thoroughly assess the entire car before suggesting a repair.

3. Avoid engine performance problems

While a dirty cabin air filter can harm the AC system, an old engine air filter can cause engine performance issues. As the engine filter clogs with airborne particles, it’s harder for air to flow into the vehicle. This affects the engine’s performance and the car’s ability to properly accelerate.

4. Increase gas mileage

According to the Car Care Council, replacing a dirty filter can improve gas mileage by as much as 10%. Considering your car’s engine can require more than 10,000 gallons of air for every gallon of fuel, clean oxygen is crucial to efficient engine operation. A clean air filter allows pure air into the fuel-air-mix while a dirty air filter restricts airflow and decreases fuel efficiency.
