Keurig K50 vs K55 Comparison

While there are many similarities between the two coffee makers, if you’re still on the fence, there are some minor details that may help you make the right choice. Below is a comparison of the different features of the two widely popular coffee makers.


The Keurig K50 features a semi-metal design with carbonate plastic, giving the machine a premium look. On the other hand, the K55 comes with an innovative, all-new design with advanced durability.

At first glance, both these models look almost identical so it’s hard to know the main differences without digging a bit deeper.

The K55 does include a smoother-looking design, making it look slightly more compact. However, both of these coffee makers have a similarly sleek design.

The main difference between the Keurig k50 vs k55 would likely be the size and weight. The former is slightly smaller, with the latter housing some additional features.

If you are lacking counter space, the K50 is the smaller and right choice for you. However, if you have unlimited space and are looking for something colorful, the Keurig K55 is the one for you.


Both these models offer the same 3 brew size options and are compatible with a wide variety of K-cups. The K50 Keurig coffee maker, however, offers a ‘Strong Brew’ feature, which gives you the option to get a stronger and bolder cup of coffee. So for those of you who love a stronger cup of coffee in the morning, the K50 is the better choice for you.

At a glance, the K55 coffee maker took around 1 minute to brew a cup. The K50 took about 1 to 1.5 minutes, which is slightly slower but not that significant. Both the K50 and K55 are designed to be quick and efficient and have proven to make a wonderful cup of coffee in about a minute.

The K55 is definitely a bit faster, so if speed is what you’re looking for, this option is best for you.


The K50 and K55 are both constructed from the same material and reinforced in plastic. In terms of strength and durability, these products are not very different.

Though some reviews have stated that the K50 Keurig machine can break down unexpectedly, the reality is that the power and overall longevity of a coffee machine is usually dependent on its usage and maintenance.

Looking at the water filter systems in the Keurig k50 vs k55: the K50 still relies solely on a mesh filter, while the K55 is also compatible with Keurig’s activated charcoal filters.

With two water filters, the K55 can offer a smoother and better-tasting coffee overall.

Ease of Use & Clean Up

Cleaning up a coffee machine can be a nightmare. However, both the K50 and K55 are easy to clean and maintain.

Both have a removable K-Cup holder, a drip tray, and a water reservoir. The K55, however, includes a ‘maintenance reminder’ feature. The descale light on the K55 will turn on when it’s time to run some descaling solution or white vinegar through your coffee maker to avoid build-up.

With the K50, you will have to remember to descale every 3 to 6 months, without any specific reminder.
