The Solofill Reusable K-cup is an alternative to the traditional, disposable K-cup; it is a K-cup that allows for multiple uses with a Keurig coffee machine. Users put their own ground coffee into the Solofill Reusable K-cup to produce a cup of coffee.
The instruction manual and a chart for the Solofill Reusable K-cup's compatibility with machines other than the Keurig are listed on Solofill's website. Three models of the reusable cup are available as of 2015; each has unique features but all are made to be used multiple times. The ability to reuse the Solofill Reusable K-cup reduces the waste produced by the traditional one-use K-cup.
