Review on Culligan D 250A D Sediment Replacement Cartridge: Enhanced Filtration for Cleaner Water by Sean Patel

UPDATE - WOW WHAT A BUG This really fits my SY-2500 BUT I did a little research and found that my Culligan SY-2500 is made by PENTEK and these are EXACTLY THE PENEK FILTERS PACK LESS THAN HALF THE PRICE under the Pentek brand so right after I bought the PENTEK replacement filters for less than HALF THE PRICE. I bought them here at Revain and they are EXACTLY the same. Shop them here at Revain. They are listed as "Pentek - 155584-44 P-250 Sink Water Filter Kit". Now I will know better in the future. MY ORIGINAL RATING was 5 STARS but now that I bought them under the PENTEK name (Culligan production kit and EXACTLY THE SAME) I feel cheated by Culligan asking more than DOUBLE the price of Pentek cartridges. HERE is my original review. Perfect for my SY-2500. If only I could get the right o-rings now. Calligan says to get the rings or -233. I bought non-genuine 233 compatible o-rings but they are too big and too thin. Now I will try the original Culligan brand and hope for the best,
