Bests & Worsts Reviews from Amazon

I've had this filter for exactly a week now. Been having to run tap through it multiple times, for the water to taste clean. But that wasn't a big deal to me. The real issue is, I just poured a little water to make tea with, looked in my cup, and noticed black flecks in there. Like little specs of dirt. I thought (since it was primarily at the bottom) that it might be coming from my cup (even though I'd just rinsed and wiped it, before pouring the water in). So I poured the same water through the filter again, and wiped the leftover specs from my cup, while it filtered. When I poured it again, I saw the black specs again!... Even after filtering it a 3rd time, I still saw specs. Less than the first time, but still unnerving. I decided to compare, and see if it's stuff from the unfiltered water, getting through. So I poured a cup of straight tap, and THAT was actually CLEAR. I don't know if during the filtration process, the metals clump together, and THAT'S what I see as specs. But either way, I think it's reasonable to expect whatever it is, to not get through, and for your water to be clear, especially after multiple filtrations. And ESPECIALLY after only a week of using the filter.
