Keurig K-Supreme Single-Serve K-Cup Pod Coffee Maker, 66 oz Reservoir

Yes, any standard K-Cup pod works, including store brands. Larger K-Carafe and K-Mug pods are not supported on this model.

You can, with a My K-Cup Universal Reusable Filter. It is sold separately and drops into the pod holder in place of a K-Cup.

Lift out the drip tray and you get about seven inches of clearance, which covers most standard travel mugs. Very tall tumblers will not fit.

The panel lights a descale indicator when it is due, typically every three to six months depending on your water. Run a descaling solution or a white vinegar and water cycle through with no pod, then two or three plain water cycles to rinse.

It slows the brew so the water spends longer in contact with the grounds, which gives a more concentrated cup at the same volume. It is not the same as choosing a smaller cup size.
