Which Keurig Holds the Most Water?

A commercial Keurig model like the Keurig K155 OfficePRO® Premier Brewing System is your best bet if you want to maximize the number of cups per brew, as this has a reservoir that can hold 110 ounces of water. However, if space is an issue, an average-sized Keurig like the K-Classic would be sufficient as this will still give you at least 6 cups of coffee per brew.

Most Keurigs have settings that can brew cups with 6, 8, or 10 ounces of liquid. 

Do All Keurigs have a Water Filter?

Most Keurig models employ a water filter to minimize build-up of excess minerals that can muck up your machine. However, the smaller models (K-Mini, K-Mini Plus, and Rivo) do not have these water filters. For these, it is recommended that you already use filtered water to brew your beverage.

Drinking coffee can be a personal activity for each one and we tend to use our own drink holders to enjoy the beverage. Keurig coffee makers typically brew 6, 8, or 10 ounce. However, cups and mugs come in different shapes and sizes.

In the office, you may have a personal mug that you use at the breakroom. At home, you have mugs or cups that you may match to the rest of your home décor, or each cup may be unique and quirky. You might even prefer using travel mugs.

On average, Keurig machines can fit cups which are 4-5 inches tall. Those with a removable drip tray can even accommodate travel mugs up to 7 inches.

In Summary

Keurig comes with a wide selection of models with different capacities.

Whatever you may need, Keurig will have something for you.
