Keurig K150 vs K155: What's The Difference?

Keurig K150 vs K155 — do you know the differences between these two similar models?

Both the K150 and K155 are part of Keurig’s commercial product line: the OfficePRO series.

They featuring a simple one-button brewing system, a colorful user interface and even bi-lingual compatibility.

Neither is My K-Cup compatible.

And I’d actually like to take a second to point out a nuance here. There are actually 3 different models of OfficePRO brewers:

  • K150
  • K150P
  • K155

That “P” is actually what makes the biggest difference.

Do you know what that difference is?

This is The Coffee Maven’s Keurig K150 vs K155 Showdown.

Keurig K150 vs K155: The Differences

There's only one difference between the K150 and K155: The K150 offers a larger 12 oz max brew size.

Other than that, the K150 and K155 are the same brewer.

Neither is compatible with direct water line plumbing. You need the K150P for that.

All three models have impressive 90 oz water reservoirs, which are good for about 7-14 servings (depending on the brew size).

For some business or office break rooms, the reservoir alone might be sufficient.

For settings with higher throughput, re-filling the reservoir so frequently may be challenging. Keurig makes models which offer direct water line plumbing:

The K150/K150P/K155 is generally the much more affordable option for break rooms, cafes, lounges, or other commercial areas.

10 oz Max Brew Size
A sleek, UL Commercial listed brewer with a 90 oz reservoir and color touch LCD display, the K155 is designed for office use but is nearly identical to the customer-minded K150 (or K150P for direct water line compatibility).

I'm Bryan but most people know me as The Coffee Maven. I grew up outside Boston, Massachusetts and received my Bachelor's degree in Biochemistry from Providence College. My first introduction to coffee was during my college days, when I used it as a source of caffeine to fuel late-night study sessions, but soon I became obsessed with the chemistry of coffee. How did changes to water temperature or contact time affect its taste? Why do beans from Africa taste fruity while beans from Indonesia taste spicy? I launched The Coffee Maven in February 2017 to explore these questions and help others brew their perfect cup. Welcome to my site, and thanks for reading!
