A: Purchasing the $15 water filter kit will help minimize scale build-up, and prolong pump life. I have absolutely no idea why Keurig decided not to include these with the initial purchase.

A: Although Keurig no longer includes water filter kits with your initial purchase, using filtered water is important for reducing scale build-up, prolonging the machine's life, and improving flavor.

A: Keurig used to include in-reservoir filter kits, recommending that the charcoal filter be replaced every two months. Now you have to buy the filter kit separately, which retails for about $15.

A: The K-Duo coffee maker is compatible with the Keurig Short Handle Water Filter Starter Kit, however, it is sold separately. This is an optional accessory and not required in order to use the coffee maker. We hope this helps!
