    These are great filters I get my water from Lake Michigan for my cottage in Northern Michigan. Before I was getting mold with ordinary sediment filters at the entry point. I just checked it after 2 weeks in the water and its completely fine. These filters are so much better than the garbage you get it at home depot this is really good company to work with. I had one cracked filter and all they asked I take a photo of it and they promptly sent out a new one.

    By on
