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 Zach Flame

They have an extra layer of micro-mesh between the fine grains of charcoal and the outer container bag, so there is absolutely no black water from charcoal dust. Delivered packed in a carton. The container box is a plus as it provides neat storage and a convenient location. I've read the negative reviews and don't see any of these issues and can't imagine how they could be real. I have had Keurig brewers for 20 years and have switched 4 brewers. These charcoal water filters fit any Keurig model that uses a water filter and are excellent at removing any flavor from tap water.
