You are correct that the PUR CTRF-5050 has been discontinued. Actually, it was discontinued quite a while ago. Unfortunately, there is no replacement that will work in your current system, so you will need to replace your system. We would be happy to help you find a replacement for your countertop filter system or a different type of system if you prefer.
You can see our countertop systems at
Countertop water filter systems and counter top filters from Culligan, Ametek, USFilter, and American Plumber. The QMP602 and QMP603 have been very popular. We have also sold quite a few of the Countertop RC540T35-T Reverse Osmosis Systems.
Thank you,
