Since there is such a wide variety of filter media options, it is important that you learn about some of them. This will help you choose the greatest.

The top models on the market today use a nanofiber filter media. This virtually guarantees that even the smallest particulates are caught before getting into your engine. The more effective your filter is at doing its job, the lower the chances will be of engine damage later on.
