The US-EZ-1 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-1 contains everything needed to remove the taste and odor of Chlorine and particulates (class III) from 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.

This Culligan undersink 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-1 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 III.

Culligan has been a trusted water filtration brand since 1936. Get Culligan water treatment without calling the Culligan man!

Filtering works well but the fixture turns in the mounting whole when turning the water off & on.
