Review title: works just fine
Product review: This air filter stayed one year in my 2003 Prius and still looked pretty new. I would occasionally take it out, tap it on the driveway, and then run my shop-vac across it. I guess I'll get another one. It seems strange to give five stars to a product this simple - what could it do that is exceptional? So I think four stars will be just right.
