Replacement cartridge for water filter kit P/N 16448. The manufactures recommend these are changed every 4 to 6 months depending on usage and water conditions.
“I have been using Calslim cartidges from BES for many years and I am sure that these will work as well as usual. However, these latest ones are smaller in diameter than previously and slide out of the existing clips, so I have had to wrap them with tape. If you are buying a new complete kit you won't have this problem.”
