The US-EZ-4 Culligan Under Sink Water Filter System installs easily beneath your kitchen or bathroom sink to deliver filtered drinking water right to your tap! The Culligan US-EZ-4 contains everything needed to remove bad tastes and odors, the taste and odor of chlorine, class I particulates, sediment, turbidity, lead, mercury, VOCs, MTBE, cysts such as cryptosporidium and giardia. The US-EZ-4, unlike the Culligan US-EZ-1 and US-EZ-3, will also filter our chloramines from your water, which more and more municipal water supplies are using as a disinfectant. To remove Chloramine, you need a genuine chloramine filter a carbon filter that filters chlorine from your water will not remove chloramines in your water. This filtered drinking water is then dispensed from a faucet devoted exclusively to your filtered water. This separate faucet will extend your filter life, since you can still wash dishes with unfiltered water and use the filtered water for drinking and cooking. Not only that, but this lead free faucet contains a built in filter life indicator so that you'll always know when to change your filter.

This Culligan under sink filter is an easy change filter, meaning the replacement filter cartridge is changed with a simple twist of the wrist. Installing the Culligan US-EZ Filter System is similarly easy, due in large part to the filter head's built in bracket. You'll never have to buy bottled water again when you have filtered drinking water on tap! This Culligan US-EZ-4 is tested and certified by NSF International to NSF / ANSI Standard 42 for the aesthetic reduction of chlorine taste and odor and nominal particulate class I, and chloramines, as well as to Standard 53 for the reduction of turbidity, MTVE, VOCs, Mercury, Lead and Cysts.
