I have a model RFG298HDRS Samsung refrigerator built in 2012. The fridge has been great and still works except for one small issue: new HAF-CIN water filters do not work. In fact, Samsung doesn't even list this model on the filter finder page, almost as if they didn't expect their product to last more than 10 years. 

I've been purchasing genuine Samsung water filters for the life of the fridge, and the last ones I bought won't work at all. The water can barely make it through the filter due to a design change. When I remove the filter, the dispenser works fine. Samsung seems to have value engineered themselves right out of a repeat customer when the time comes when I really need to replace this refrigerator.
