The Keurig B150 offers one more brew cup size than the Keurig B155. The B150 allows you to brew 4, 6, 8, 10, and 12 ounce brew sizes, whereas the B155 only allows you to brew 4, 6, 8, and 10 ounce cups. Despite this small difference, the B155 and B150 brewers are virtually identical in terms of appearance, features, and functionality. In fact, both coffee makers come with a large 90 ounce water reservoir and color touch screen. They are fully programmable, NSF certified for use in food service, and best of all- the B150 and B155 brewers are both direct water line plumb kit compatible.
