When buying a coffee machine for an office, there is a bit of a shift in criteria. Home units with smaller reservoirs have quick water heating and brewing times.

Reducing the number of required refills, fast brewing times, and heavy-duty use become more important than stylish design and complimentary variety K-Cup packs.

The focus on cup personalization is also less, although temperature control is still a feature that you may want for your office. Durability and easy maintenance should also be a high priority when you are searching for the ideal brewer.

Keurig’s 2.0 Commercial OfficePro product line caters for the office environment. These office brewers seek to provide all the practicality features you need for your office brewer without compromising quality brewing.

Two of the favorite brewers in this product range are the Keurig K145 and the Keurig K155 . These units have similar dimensions and designs, but there is a significant difference in their price.

In the comparison review below, we will be taking an extensive look at these two models’ features and benefits to determine which one of the two is the best option for your office.

Pod Compatibility and Brew Sizes

Neither the K145 nor the K155 is compatible with reusable My K-Cups. Since Keurig developed both models for office use, this may not be the biggest problem, however. Changing pod and My K-Cup assemblies can be a hassle in certain environments.

Both the K155 and K145 are part of Keurig’s 2.0 product range, so they are only compatible with Keurig licensed 2.0 K-Cups. Furthermore, both models can brew cup sizes of 6 oz, 8 oz, and 10 oz. This is where the brewing capacity similarities end.

The K155 can brew additional cup sizes of 4 oz as well as a travel mug capacity of 12 oz. The K155 has a water reservoir capacity of 90 oz, allowing the brew of nine 10 oz mugs before it is time for a refill. In comparison, the K145’s water reservoir capacity of 48 oz is relatively small.

The difference in water reservoir capacity between the two models is quite significant, especially if you are looking for a unit that you can use in a busy office. The more you have to refill the reservoir, the longer the total water heating time will be.

If you have a smaller office with a staff of five or fewer people, however, the more affordable K145 will work.


Features that the K155 and the K145 share include an Auto Off function and a removable drip tray for easy cleaning.

Unlike the K155, the K145 doesn’t feature a color touch LCD screen or programmable clock. Instead, it has button controls for powering the unit on or off, starting a brew, and drain brewing. The K145 also has a selector knob to choose a brew size.

Another significant difference between the two models is that, unlike the K145, the K155 allows for temperature control. The factory temperature settings for the K155 are 193 degrees Fahrenheit for K-Cup pods and 197 degrees Fahrenheit for K-Carafe pods.

Since the focus of both models is on quick and straightforward interaction, neither one features brewing strength control. As a bonus, both the 145K and the 155K come with a variety K-Cup pack.

Commercial Features

Since these two models are intended for office use, you can expect to find an array of features that are typically absent with garden variety kitchen brewers. Both brewers are incredibly durable and have heavy-gauge housing and component construction that allow for repeated use.

A drawback of the K155 and K145 is that you don’t receive a water filter with either one, and you will have to buy a compatible filter, which increases the initial costs.

The K145 has the added benefit of a drain brewer function that allows for easy cleaning. Although the K155 doesn’t have a drain brewer, it features an easy drain function that you can use whenever you have to transport or store the brewer.

The K155 is NSF certified, which allows for use in foodservice outlets. Both the K155 and the K145 have UL commercial certification, which is valuable for offices in controlled environments.

Despite the K155’s water reservoir capacity, it doesn’t have a direct water plumbing capability. According to some reviews, an arrangement between people to fill up as they use the machine works quite well.

Another valuable office feature of the K155 is its Quiet Brew Technology. You don’t want a brewer that disrupts your entire office every time someone is using the machine. Many reviewers found the K145 to be a bit loud for a productive environment.


At first glance, the two most prominent difference between the K150 and the K140 are the capacity of the water reservoir and the price tags. The Keurig K155’s water reservoir can take 42 ounces more than the Keurig K145, which is about 5 cups.

Reducing the number of refilling can save frustration and time. Whenever you have a new reservoir full water at room temperature, it can take some time for the water to reach the optimal temperature. For this reason, it may be worth investing in a 90 oz water reservoir.

The K155 can also brew one more cup size at either end of the K145’s brewing size spectrum. It has a color LCD touchscreen, it offers brewing temperature control, and it is certified for use in foodservice outlets.

When it comes to features, the K155 is by far the better for an office environment – if you disregard its price completely. For smaller offices that don’t have a large budget, the K145 is a high-quality, user-friendly, and affordable alternative.
