Keurig K50 vs K55: What's The Difference?

Keurig K50 vs K55: What’s the difference and which is better for you?

I’ve read all of the other search results answering this question, and these are their explanations:

  • They have slightly different dimensions and/or weight
  • The K55 has advanced Auto-On functionality
  • The K55 is compatible with a charcoal water filter

Wrong, wrong, wrong.

Do you really want to know the difference between the Keurig K50 and K55? Here’s the truth.

They’re exactly the same.

Don’t believe me? Check out this side-by-side comparison.

So, why did Keurig market the K50 and K55 as different models?

The Answer: Included Accessories

The K40, K45, K50, and K55 are all basically the same machine.

For the most part, the only difference is what's included. With the K55, that's a water filter starter kit.

If you want the water filter starter kit with the K50, you need to purchase it separately.

Reviewing the K50 vs K55

Both the Keurig K50 and K55 are part of Keurig’s original line of brewers, now called the Keurig 1.0 line. These brewers feature your basic “pop in a pod” technology whereby users — err… — pop in a pod.

There aren’t a lot of features, there’s little additional functionality, and the brew sizes are limited to a modest 10 oz.

The pros of these models? They’re relatively inexpensive, the brewing technology is simple and proven, and they’re about as intuitive as it gets.

However, that simplicity could be construed as a downside.

Because these models don’t have all the bells and whistles of the Keurig 2.0 brewers (models K200-K575), you don’t have much control over your final coffee.

For example, let’s say you want an 8 oz coffee. You pop in a pod, the machine pumps enough water to brew the 8 oz coffee, and you’re done.

Now you want a 10 oz coffee. You pop in a pod, the machine pumps more water…but did you add more coffee? No, you didn’t. This mean a 10 oz coffee will be slightly weaker than an 8 oz coffee, and there’s nothing you can do to fix this except get a compatible reusable pod. This way you can add ground coffee to your desired volume.

If you want a Keurig machine that’s a little more robust, check out something that Keurig 2.0 line or the recently release Keurig K-Select.

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!
