3M Aqua-Pure Sump Replacement Water Filt

Doesn’t work that good, pots still get stains when boiling by the water that passed through this brand new filters. And once it’s used a lot instead of getting more and more clogged ..so that you know that you have to change it and you also know that the bad stuff stays stuck in there in that filter.. No, no, no! This filter can crack and then it lets things go through into your sink water. That’s why they say to change this filter every six months (even if you don’t use that sink so often).. Aaaand, even when it’s new I can see my water-boiling-pot has some STAINS from the water that came through this “highly praised” *filter*.. If you know of a better one than these, please let me know. Thanks.
