I took my time replacing the water filter this go round so needless to say, my refrigerator was almost producing dirt. Not my proudest moment. In doing so, I was able to notice the cast contrast between my water before and after the filter change. I dumped the existing ice, filled up a jug enough times that I thought the old water was flushed from the system, and gave it a taste test. If unseeded clouds had a taste, this would be it!Installation was the easiest part to be honest. There was little water left in the old filter when I removed it so be mindful of that. I made a little mess. Other than that, there were no issues. I should have purchased sooner.
