Ametek US Filter has discontinued the Ametek CT-10 countertop system and the replacement water filter. We have been unable to find an interchangeable replacement filter from any manufacturer due to the unique size and shape of the filter. We recommend purchasing a new countertop system that uses standard 10" L x 2.5" W filters. Many manufacturers make the 10" x 2.5" standard size filters so we will always have replacement filters available.
The countertop system that looks similar to the Culligan CT-10 is the CTW-10-WF
