Included is a capsule container that can hold up to 12 spent capsules, a 15-bar pump responsible for the brewing, and a Mavea Water Filter that relies on a four-stage filtration system to purify the water (which is assumed to be tap), thereby reducing mineral buildup. As of early 2011, there are only four types of available capsules: Medium Roast, Dark Roast, Lungo, and Decaf.
