This filter is only half of the system. The other part is a nozzle that is installed under the kitchen sink on the cold water line. Together they make the best filtered water I've ever tasted. It also filters out all the bad. I'm certainly no plumber, but I installed this entire system in 30 minutes with just a wrench. The filter is changed every six months, so the price is good there too. Should have done that many years ago.
