Keurig K50 Vs Keurig K55: The Similarities

Before talking about the difference, it’s essential to understand the similarities between the coffee makers. These brothers from Keurig have a handful of similarities, and that’ll help you in making a buying decision.

Single-serve Coffee Maker

Both machines from Keurig are single-serve coffee makers. Over the years, coffee lovers have started preferring single-serve machines as they are convenient, and there is no fuss about handling a carafe. 

Just place the mug under the dripper, and you can brew a cup of coffee within minutes. 


Keurig K50 and K55 both are highly durable coffee makers. The plastic is BPA-free and feels solid. Keurig is popular for manufacturing machines that last longer, and most of their parts are dishwasher safe.

Compatible with K-Pods from Different Brands 

Keurig has designed both machines to be compatible with K-Pods of a different brand. If you don’t want to use the Keurig K-pods, you can look for other brands that manufacture these pods. 

Design and Aesthetics 

Both machines look alike, and you cannot spot any major differences. The footprint is the same, and the water reservoir is on the left side of both coffee makers. 

Furthermore, both machines are available in multiple color options, but Keurig k55 comes in white as well. 

Ease of use 

I own Keurig K55, but one of my friends has Keurig K50, so I got a chance to try my hands on both machines. Both are easy to use. All you need to do is put the K-pod in place, add water to the chamber and press the brewing button.


Keurig K50 and K55 both get 10/10 in terms of reliability. The machines offer multiple brew sizes, and the taste of coffee remains the same since you are using a K-pod. 

Auto shutoff 

You get auto shutoff with both Keurig coffee makers. The machines turn off after 2 hours, and you can use them to set a schedule for brewing coffee. 

Keurig K50 Vs Keurig K55: The Differences

There are several differences between these coffee makers from Keurig. Both may appear the same, but there are many features that set them apart. 

Here are the major differences I experienced while brewing coffee with these machines: 

Brewing Speed 

The brewing speed is a big factor as everyone needs their favorite coffee prepared within minutes. Both coffee makers from Keurig prepare a cup of coffee in less time, but there’s a gap of 30 seconds. 

Keurig K50 takes 30 seconds more in brewing coffee. To be precise, the machine takes around 1.30 minutes to brew a cup of coffee. 

On the other hand, Keurig K55 is quicker and takes less than a minute. My coffee maker takes around 40-50 seconds, and the drippers start pouring coffee into the mug.

I compared both machines on the 8oz brew capacity to find out the exact difference. A 30 seconds difference may not be a big deal for most, but for people like me who are always running late, every second matters.

Built-in Filters 

When I wasn’t worried about the filters when looking for the differences between these Keurig machines. However, the filter has a significant impact on the taste, so I made sure to cover the water filter in this post.

The K50 comes equipped with a mesh filter that is great for filtering water. However, the K55 uses a dual filter that includes a mesh filter and a charcoal filter for better filtration. 

The activated charcoal filter in K55 results in a cup of coffee that’s smooth and perfect to start an amazing day.

Customized Coffee Brewing 

You get customized brewing options on both Keurig models. Just pressing the button will help you choose the cup size and strength. From bold to regular, these coffee machines from Keurig serve you with everything you need.

However, K50 is better if you need a caffeine punch to fend off the laziness. The coffee maker has a Strong Brew button that you can press to get a cup of bold joe.

You can even set the strength to bold with the K55 or K Classic, but the caffeine kick isn’t that great. And now you know which coffee machine is better to have bold coffee that tastes great.

Cleaning and Maintenance 

Cleaning and maintenance of a coffee maker are essential to keep it running. Cleaning both K50 and K55 is easy, all thanks to the removable K-cup holder, water reservoir, and drip tray.

However, the K55 model goes the extra mile and rewards you with the freedom of cleaning. The coffee maker comes with a Maintenance Reminder, so you’ll know when it needs cleaning. 

Furthermore, Keurig K55 has a descaling feature as well that helps you get rid of the scale. On the other hand, K50 doesn’t come with such features and requires manual cleaning. 

Here’s a complete guide to clean the K50, coffee machine. 


For most of you, weight may not be that important, but it really matters, especially when transporting the coffee maker. The Keurig K50 weighs around 7.6 pounds, whereas the K55 weighs 12 pounds. 

The K55 is almost double the weight of K50. If you are looking for a machine that’s compact and lightweight, go for K50. 

However, if you aren’t looking to change the coffee machine’s position any time soon, consider K55. 


Keurig K50 and K55 give neck-to-neck competition to each other in terms of convenience. Both machines are easy to use, but K55 is a tad higher, and the credit goes to the smooth buttons.

You need to press the buttons a little harder with Keurig K50, but this is not the case with K55. Although this may not be a noticeable difference, sometimes the buttons get too hard.


There is a big difference in terms of price. You get the K50 for somewhere around $79-89, depending on the deal you are getting.

On the other hand, the Keurig K55 model  or the K Classic can cost you more than 100 dollars. K55 is a new model with updated prices, so it’s evident why Keurig has priced it a little higher.

Keurig K50 Vs K55: Final Showdown 

Now that you are aware of the major differences between both coffee machines, it’d be easier for you to select the right one. Keurig K55 is for people that need their coffee to get ready instantly. 

Also, the coffee maker has a cleaning indicator, so cleaning it becomes a breeze. Another feature the machine offers is the dual-layer water filter that removes most of the impurities from water. 

Keurig K50 is a great choice for folks looking for a reliable single-serve coffee maker under 100 bucks. The machine shares most of the features with K55, and you get great-tasting coffee every time you tap the brew button.
