Question: are keurig k cups one time use?
Answer: K-Cups are designed for one use only. You use the K-Cup once and then throw it away. If you find that wasteful, and a lot of Keurig brewer owners do, you can get a Keurig My K-Cup Reusable Coffee Filter . This is a reusable filter to which you add loose ground coffee each time you want a coffee.
