Keurig K-Duo Hot & Iced Single-Serve & Carafe Coffee Maker Black: Electric Drip Coffee Pot, 72 oz Capacity

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: 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: 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!

A: According to the website, FoodDrinkTalk Pro, Keurig's decision to no longer include water filtering kits with new coffee makers is based on, "Design Simplicity", "Cost Savings". and "Convenience".

A: An excellent question. The $15 filter kit is required for using charcoal filters. Filtering water reduces the rate of scale build-up and helps to prevent premature pump failure.

A: Thank you for your question. The K-Duo coffee maker is compatible with the Keurig Short Handle Water Filter Starter Kit; however, this is an optional accessory and is sold separately. We hope this helps!

A: Filtered water is important for reducing scale build-up, prolonging the life of the coffee maker, and improving flavor. Until recently, Keurig included filter kits with each coffee maker purchase.

A: Keurig did recommend changing the charcoal filter after two months or 40 gallons. They no longer include a filter holder with your initial purchase and no longer recommend filter change intervals.

A: Yes, this is the 2nd generation K-Duo coffee maker.

A: The first generation K-Duo had a stainless steel thermal carafe that has been replaced with a 12-cup glass carafe. It also has a hotplate that automatically turns off after 2 hours.

A: Yes, this is the second generation K-Duo coffee maker. Thank you for your question!

A: Yes. When brewing with the carafe, you will need to use a flat-bottom paper filter designed to fit 12-cup brewing baskets.

A: The K-Duo Single Serve & Carafe coffee maker can fit a flat-bottom paper filter that is compatible with a 12-cup coffee maker.

A: The hotplate can be toggled on or off by holding the carafe button in for 3-5 seconds. When manually turned on, the button will be lit red and the hotplate will remain on for 2 hours.

A: Once the brew is complete, the heating plate will automatically turn on and remain on for 2 hours - the CARAFE button will illuminate red. To turn off the heating plate, press and hold the CARAFE button until the light is no longer illuminated. We hope this helps!

A: Keurig recommends using their Short Handle Water Filter Starter Kit, which costs about $14. I used the holder that was included with my previous Keurig and bought a couple of new charcoal filters.

A: Thank you for your question. The K-Duo coffee maker is compatible with the Short Handle Water Filter Starter Kit. We hope this helps!

A: The K-Duo (Gen 2) has five water injection needles that pierce single-use pods. To prevent damage, only reusable pods that are specifically designed for this coffee maker should be used.

A: Thanks for your question. The K-Duo coffee maker is compatible with the Keurig My K-Cup Universal Reusable Coffee Filter for the single serve option, which is designed to be used with your own ground coffee. Hope this helps!

A: If you're describing how the carafe lid swings open when the carafe is tipped past 90-degrees, I don't believe this issue has been corrected as of yet.

A: Thank you for your question. The K-Duo Gen 2 coffee maker comes with a 12-cup glass carafe that is designed to limit dripping. We hope this helps!

A: Glass pot. Previous generation pot is NOT compatible.

A: Thanks for your question Nicky. The K-Duo coffee maker includes a 12-cup glass carafe. We hope this helps!
