Review on Housewares Solutions Pack of 12 Replacement Charcoal Water Filters - Keurig Brewers Compatible Water Filter Cartridges Universal Fit (Excluding CUISINART) for Keurig 2.0 & 1.0 Coffee Makers by Jessica Gibson

While these filters work well, they contained a lot of carbon dust that required repeated soaking and rinsing to remove. The three photos in the review are of three separate 10 minute soaks and you can see the soot level in the water. It took these two filters about 10 soaks to get mostly clear water. Interestingly, one filter floated and the other sank - I don't know what to do about it. Right now I don't see any gray water in the Keurig water tank. Taste and fit seem good. My understanding is that carbon is fine for human consumption, but FYI if that's an issue for you.
