Product review (1 stars): I had this same issue with the OEM Samsung replacement filters and was glad to find the EcoAqua ones that fit
I bought these filter because they fit my refrigerator. It seems that at some point the design of the locking tabs was changed. They used to have 2 squarish tabs and now have 3 pointed ones. They are not interchangeable. I had this same issue with the OEM Samsung replacement filters and was glad to find the EcoAqua ones that fit. The last order I did now have the updated design that won't fit.
