Your car's air filter plays a vital role in keeping the engine clean and free of dirt and debris. A dirty or clogged air filter can lead to a variety of problems, including reduced fuel efficiency, increased emissions, and even engine damage.

When to Check and Change Your Air Filter

Recommended Intervals

It is generally recommended to change your car's air filter once a year or every 15,000 miles, whichever comes first. However, if you drive in particularly dusty or polluted environments, you may need to check and replace it more frequently. Regular checks can help you catch issues before they become serious problems.

How to Check Your Air Filter

Checking your air filter is a simple process that you can do yourself. Here’s how:

1. Locate the Air Filter: The air filter is usually found under the hood, near the engine. In newer cars, it is often rectangular and located near the radiator or fender wells. In older cars, it is typically round and located near the engine.
2. Remove the Air Filter: Open the air filter housing. This may involve unscrewing a few screws or unclipping some clips.
3. Inspect the Air Filter: Hold the filter up to a light source. If you can see light clearly through it, the filter is still good. If the light is obstructed, it’s time to replace the filter.
