Best one out there. Love this water filter.

I bought the filter assembly 3 years ago and have not had any issues with it. I get the filter that removes the lead. I have used the other filters that don't take out the lead but that was by mistake because I was looking at cost of the filters. I now buy the filter that removes the lead. I installed it in the bar sink. I use that sink for my coffie and drinking water. I am going to buy another one for my refrigerator because it is cheaper than the GE refrigerator filter and lasts longer. Love this water filter.
