Your car's air filter is very important since it maintains some parts of your car system clean and free of dirt. If your air filter doesn't work properly and dirt enters your car this might make it go through different problems, and therefore it is important that you check the filter and change it when necessary.

It is recommended that you change your car's air filter once a year or every 15,000 miles . But, if you can check it once in a while and replace it as soon as it needs it this would be much better. Checking it is a very easy thing to do and replace it is not complicated once you learn how to do it. If you wish to check your car's air filter yourself, you can do so by using a light from inside pointing outside and check how bright it looks through it. If you see the light clearly, then your air filter is still good, but if you can't see much of the light then it indicates the filter needs to be changed.

If your car is rather new, its air filter is probably rectangular and you might find it located under the hood, near the radiator area or the fender wells.

If your car is older, the air filter will probably be of a big round shape and located near the engine area. It might probably be screwed, and all you might need to do is to unscrew the cover, let the air filter come out, and place the new one instead of it.
