Product review (1 stars): You get what you pay for
I use water strips to test the hardness of my water.  This filter did nothing to improve the hardness.  I use water everyday and even after a months use the water was still very hard.  The flow is also slower than with the GE filters.  I will pay the extra money for the GE brand because I actually want to drink water that tastes good.  I bought the three pack of this brand and just threw away the other two because this so called filter doesn't do what a filter should.
