Product review (5 stars): Don't bother with any other...
Best filter out there by far, you will really notice the difference after you install it. Speaking of which, it is just a screw in cartridge that takes all of ten seconds to remove and replace. Don't bother with the cheaper generics offered by some along side this one. Have tried one and it wouldn't even screw in properly and restricted the flow to a trickle. Total waste of money. Stick with this one, you'll never have a problem...
