Great price. It does what it's supposed to do. Keeps my air flow clean. Super easy to install, I can't believe mechanics charge to do this. Once you see how easy it is, you'll save yourself that expense. The material is top-quality charcoal, so it cleans all the nasty mold particles from getting into the vehicle. There is no smell, and that is a plus.
