What does a car air filter do?

Your car’s air filter prevents mucking up your engine’s air supply by keeping out insects, dust, debris, sand, and particles because your engine needs clean air for combustion.

How often should I change my car’s air filter?

According to your vehicle’s maintenance schedule as listed in your owner’s manual.

In general, you should inspect the air filter every 15,000 to 30,000 miles to see if it needs replacing.

You may have to replace the air filter more often if you frequently drive in dry and dusty conditions, such as in a desert climate.

How much is an air filter for a car?

Air filters are one of the least expensive things to buy for regular car maintenance at an average cost of $15 to $25. Costs depend on the size needed, and the air filter size depends on the size of your vehicle’s engine.

How do I know if my car needs a new air filter?

Look for these signs:

1. A dirty or discolored air filter is the top sign your car needs a new one. Look for dark and dirty splotches and patches on the air filter.
2. Spitting or popping noises when your car is idle. This may be a sign of a clogged filter somewhere, so you should check your car’s air filter for obvious signs of clogs, dirt, or debris.
3. Poor engine performance. If you notice any sudden changes in how your car performs, such as struggling to get up a hill or when accelerating, a dirty air filter may be one cause.
4. Worse gas mileage. If you are filling up your gas tank more often than usual, the air-fuel mixture in the combustion chamber could be off. This issue makes your car use more gasoline than normal.

What is a car’s air filter made of? 

They are constructed of a plastic frame that holds a pleated, fibrous material that traps dirt while letting air through. The pleated material is typically some kind of cotton, synthetic paper, or even foam.
