Product review (5 stars): A Good Decision
We are quite pleased with our Waterfall filters. We ran more water through --- about 7 or 8 quarts before the water appeared clear --- than recommended. Installation does require moving the filter to the lowest angle; you still will find it takes some muscle to extract the old filter. This was also true of the Kenmore filters which are 4X's the cost of Waterfall with no better performance.
