Product review (5 stars): Perfect fit
The filter fit perfectly in my Maytag refrigerator designed for the UKF8001. The water pressure seems unaffected and the water tastes clean. The filter came with a little stick on replacement indicator with no instructions. It is pretty obvious that you peel the backing and stick it inside the refrigerator. A small red line with start to grow as the filter ages. Pretty neat.

An advantage of this Aquacrest filter is that it is certified for NSF/ANSI 42, 53, and 401 meaning that it is more effective than other filters.
