This filter came with my Whirlpool Refridgator , and I have been using the drop brand for the last year. It improves the taste of the water , and the ice is a very pretty white , like it is supposed to be.  Sometimes the water slows down, but only when it is time to change the filter.  You can pop the filter out , replace it again , and you will have better pressure until your new filter arrives. It doesn't get any easier.  Great  filter.
