Product review (1 stars): I wouldn't drink water from this filter if you paid me
This was the most expensive mistake I've made this year on Amazon. We purchased a new house and I wanted to ensure that the water was clean from the fridge, so I purchased these.  We followed the instructions perfectly, only to have light grey water.  We kept running more water through it over the next few WEEKS and still light grey.  We have now tried a second filter from the box, again following the instructions perfectly, only to have more light grey, "I wouldn't drink this if you paid me" water.
