Review: Water Tastes Great! - The taste of our water has improved greatly since utilizing this water filter.

This water filter has been a great addition to our house I will definitely purchase this water filter again. ## Features - 【Compatible models】: Interchangeable with Culligan RC-EZ-1, RC-EZ-3, RC-EZ-4, compatible with IC-EZ, US-EZ, RV-EZ system; DuPont WFQTC30001, WFQTC70001, WFQTC90001. - 【High-efficiency filtration】: Effectively reduce chlorine, heavy metals like Taste and Odor, Sediment, Rust and reduce Chloramines.
