How often should I have my air filter replaced?
Vehicle manufacturers vary on their recommendations for how often air filters should be replaced. Many recommend changing it every 15,000 to 30,000 miles. Checking your owner’s manual will give you the specific mileage for your vehicle. You can also consult your local mechanic for a recommendation based on your driving habits.
Driving conditions and climate can affect the lifespan of an air filter. If you often drive on dirt roads, do a lot of stop and start driving or live in a dusty and dry climate, you might need to change your air filter more often. To keep track of when to change the air filter, many people rely on a visual inspection to help determine when to replace it.
