Review on 🚰 12-Pack of PURE GREEN WATER FILTER Activated Charcoal Water Purification Filters for Keurig – Universal Application by Everett Underberg

Keurig filters have been used for years without incident. Received these a few days ago. Despite the fact that there were no instructions, I knew I had to soak for five minutes and then rinse thoroughly after using Keurig brand filters. A few days later I looked in the container but it seems to have rusted! I was able to remove any mineral deposits on the bottom of the water tank, but I can't remove them from the Keurig two-piece filter holder assembly - I need to replace them. Return Eleven unused. Back to the Keurig brand. A photo of the filter block and filter holder is attached.
