The K-Duo is Keurig’s dual coffee maker: a single-serve K-Cup brewer on one side and a full 12-cup carafe drip brewer on the other, sharing one water reservoir.
It is the compromise machine for households where one person wants a single cup and the other wants a whole pot — nobody has to settle twice a day.

Frequently asked questions
Can I use grounds in the carafe side?
Yes — the drip side takes ground coffee in a permanent or paper filter, while the single-serve side takes K-Cups. Shared tank, independent brews.
