Product review (5 stars): Replacement filter for the UKF8001 for 25% of the price of the OEM filter and it is working fine!!!
I received my order on time and had zero issues installing the filter. I ran a few pitchers of water through it until the water appeared clear. Obviously I won't know for sure how long it lasts, but we are a few weeks in and everything appears to be fine. So I'd have to say, "So far so good!!!" HaHa
