The Keurig K-Classic (K55) is one of the most popular choice for someone who is buying a Keurig for the first time. It gives you the basic Keurig features at a very reasonable price and it works with a wide range of K-Cups from different brands, so you can enjoy many beverages from coffee, tea, hot chocolate and more.
Features of the K-Classic are as follows:
- 48 oz water reservoir with water filter.
- Choose from 3 cup sizes: 6, 8 or 10 oz.
- Button controls, with a button dedicated for each cup size.
- Light indicators show you heating process, add water alert, descaling alert and auto-off.
- Removable drip tray allows you to fit a larger cup size under coffee spout.
- Your K55 will include a refillable K-Cup filter that allows you to enjoy your favorite coffee ground.
Who Is The Keurig K-Classic Best Suited For?
- It is great for a single user or a small family, since the water reservoir isn’t the largest but suitable for multiple uses before needing to refill.
- If you don’t care about advanced features like a touch screen or additional cup sizes, the K55 will be good fit for you.
- If you have a budget under $100, the K-Classic is at that price range (as of the time of writing this post).

K-Mini is a small, sleek looking brewer. It actually has more cup sizes than the K-Classic as you can brew up to 12 oz using the K-Mini. However, it does not have a water reservoir. So you’ll have to add fresh water at each brew.

The K15 is smallest Keurig brewer out there. So it makes a great choice for a single user rather than a family or a group of people.
- The K-Classic and K15 brew the same sizes of 6, 8 and 10 oz.
- K-Classic has a 48 oz water reservoir
- The K15 has no water reservoir. You simply fill as much water as you want to brew. The tank is marked with the amount for each cup size, and the machine will brew the full amount you add in at each use.
- The K-Classic has a dedicated button for each cup size as well as light indicators.
- The K15 has a single button and that is the Brew button. There’s a light indicator that guides you through the brewing process.
- Both the K-Classic and K15 are compatible with the same K-Cup pods.
- The K15 includes no accessories. It has no water filter, so it is recommended that you use filtered bottled water to brew your coffee. As for the refillable K-Cup, it is compatible but it doesn’t come included with the machine like with the K55.
Keurig K-Classic vs K145:
The K145 is one of Keurig’s Professional line made especially for office use. It is made for heavy and frequent use and has commercial-grade brewing.
Although the K55 and K145 have the same capacity and brew the same cup sizes, you’ll find that the K145 is heavier in weight, has a heavy-duty power cord and a stronger pump (which means it is much louder than the K55).
Controls wise, as the K55 has buttons, the K145 has a dial for cup sizes and buttons auto-off, on/off power and drain brewer options, which the K55 doesn’t have. Both have the same light indicators, though.
And because the K145 has a stronger pump, it is faster at brewing. It can brew a cup in less than a minute, which is faster than the K55.
Now, just because the K145 is labeled as an office machine, it doesn’t mean you can’t use it at home. Jut bare in mind that it will be very heavy and quite loud.
Note that the refillable K-Cup pod is not compatible with this model.
Which of These Machines Is The Right One For Me?
Here are some points to help you decide which machine to go for:
- Are you under a strict budget? If you’re looking to spend less than a $100, then go for the K-Classic or K15.
- Do you want to brew large cups? Then you’ll be happy with the K-Select or K-Elite. If you want to brew even more coffee, check out K-Duo dual coffee makers which brew full carafes in addition to single-cups.
- How many users will this brewer serve? The K-Classic is great for a single or multiple users. The K-Mini is best suited for a single user due to its small size.
