Keurig K150 vs K155 Review

Having a Keurig coffee maker will never be a disappointment. But if you are looking for a machine for the office, most people prefer a quieter machine. And these two models fit the bill perfectly as they are both from the OfficePRO series.

The K150 and K155 bear a striking resemblance but do they both perform the same? Are there any differences between the two models? What makes them perfect for office use? In this review, we answer these questions and also discuss the pros and cons of the two coffee makers.


Bear in mind that Keurig also has a K150P in the K150 series. For this review, we will stick to the K150 without the P.

The K150 and the K155 have very similar designs. They both are made of plastic with metal components. They are both very compact and have a sleek design to take up minimal counter space.

The main differences between the two are color and additional accessory for plumbing. The K150 is mostly black on the cabinet, and you can buy an additional plumb accessory to connect to the water supply.

On the other hand, K155 is predominantly silver in color. Unlike the K150, you cannot add the accessory to connect to the water supply with the K155. Both machines have very reliable designs, which make them durable as well.


The two models have very similar features as well. These include:

Touchscreen display – Both the models have a touchscreen display through which the settings can be programmed. Brewing temperature, as well as the brew size, can be programmed. The clock can also be adjusted through the LCD. The LCD in K155 is color while in the K150 it is in black and white.

Language setting – In both the coffee makers, you can set the language to English, Spanish or France.

Quiet brew technology – Both the coffee makers have an innovative, quiet brew technology which makes them quieter than other coffee makers. This makes both the coffee makers ideal for use in the office.

Auto on and off feature – Both the K150 as well as the K155 has an auto on and off feature. The machines are programmed to switch off if you leave it inactive for 90 seconds. This is an excellent feature as it saves energy and is also acts as a safety mode.

Differences in features.

The K150 has five cup options, which are 4 oz, 6 oz, 8 oz, 10 and 12 oz. the K155 has four cup options from 4 to 10 oz.


These two models from Keurig brew excellent coffee in under a minute, which is quite fast. The brew temperature on both the machines can be adjusted as well. They are both compatible with licensed 2.0 k cups from Keurig so you can have a wide variety of beverages from hot cocoa, tea or iced beverages of your choice.

However, neither of the machines work with My K cup irrespective of whether it is from Keurig or otherwise.

Perhaps the key difference between the two coffee machines is that the K150 comes with a heavy-duty pump which connects directly to the water supply. The K155, on the other hand, does not have this feature.

The coffee makers heat up to a nice temperature between 188 degrees F to 198 degrees F. While this is a good temperature for your caffeine beverages, many folks have an issue with the obnoxious plastic smell. While we did detect a faint odor of plastic, especially from the K150, flushing the tank with a small solution of water and vinegar significantly reduces the smell.

When it comes to the water tank capacity of the two models, both the reservoirs, hold 90 ounces of water, which is enough for up to eighteen cups of coffee.   

You can choose from the five different brew sizes if you have the K150 – 4 oz to 12 0z. If you have the K155, you can choose from 4 oz to 10 oz.

The K150 weighs 18 lbs and has a dimension 14 x 10.5 x 13.6 inches while the K155 weighs 6 lbs and has a dimension of 14 x 10.4 x 13.8 inches.


Maintenance of these coffee machines is as simple as it gets. The drip trays, as well as the water tank, are removable, which makes cleaning very effortless. The internal hot water tank can also be drained easily.

The quality of the water in your area determines how often the descaling needs to be conducted on the machines. However, the recommended frequency of descaling under normal conditions is every 3 months or so. The process must be performed using a Keurig descaling solution.

However, if you don’t have the descaling solution, using a diluted white vinegar solution can also be effective. But to keep the machines in optimal performance and also extend its longevity, using the recommended descaling solution is best.

Final thoughts.

By now, you must have concluded that there is no significant difference between the two coffee machines. They are both very efficient in their own way. The slight differences are only limited to cosmetics, which is a matter of personal taste.

The ultimate choice would be on these distinctly personal factors – If you like to have more options of brew sizes and one that connects to a water supply, and a less expensive machine, go for the Keurig K150.

If, however, you like your beverages without the smell of plastic, you don’t mind filling the water tank occasionally and take the machine with you for travels, go for the Keurig K155.
