Introducing the Keurig K50 and K55 Coffee Machines

Founded in the early 1990s, Keurig has become a respected household name. Their specialty is single-serve brewer models.

These brewers are suitable for both office and household use. Plus, they also sell a range of other great coffee-making accessories like coffee pods and carafes.

A fair warning though: Keurig coffee brewers aren’t for any coffee perfectionist. These basic machines won’t give you a café-style brew.

The Keurig models are budget-friendly machines for the average coffee drinker who just wants a convenient cup of joe.

Product Specs

Dimensions: 9.8 x 13 x 13.3 inches
Weight: 7.6 lb
Water tank capacity: 48oz
Material: Plastic

As the older of the two Keurig models, the K50 is practical and easy to use. This coffee maker is not top-quality, but it gets the job done well enough.

Standing at a height of 13.3 inches, this small machine features a standard removable drip tray and a 48oz. removable water reservoir. This is large enough for you to make a single cup of coffee a day for roughly a week without needing a refill.

Keurig’s traditional button controls make it easier to operate without any added features. There is no room for any sort of customization, but the simplicity of the design is what makes it appealing.

Our favorite feature of this coffee machine is its 30-minute automatic shuts off. This could save you a lot of money and energy in the long run.

Although Keurig advertises this model as having a brewing time of under 60 seconds, we found that it generally takes a little longer than this. Unfortunately, this isn’t the model’s only downside.

We found many complaints raised about the general reliability of the model. Many customers experienced several performance issues after a while. This is definitely something you should be aware of.



The Keurig K55 Coffee Maker

Product Specs

Dimensions: 10.1 x 13.2 x 13.3 inches
Weight: 12 lb
Water tank capacity: 48oz
Material: Plastic

As the updated model released by Keurig, the K55 is slightly larger and heavier than the K50. It also boasts several more advanced features and improvements.

Like the K50, there is no glitz and glamor about this coffee maker. It.does exactly what it’s advertised to do: brew your average cup of coffee in under a minute. Keurig finally got it right this time around!

It has kept roughly the same design, with a removable drip tray and a 48oz. removable water tank. The K55 has a much smoother exterior though, which we think gives it a more sleek look.

Plus, the new K55 machine is also compatible with Keurig’s charcoal water filters. This goes a long way to increase the water quality of the coffee.

Another handy addition is the range of new light indicators like the water-refill indicator. You also get a useful maintenance reminder that tells you when you should descale the machine.

This model has also kept its auto shut-off feature, making it a lot more energy-efficient.

Although not high-quality by any means, the K55 model is a solid entry-level coffee machine. It’s an ideal choice for those on a budget.

The Showdown: Keurig K50 Vs K55

The appeal of a decent single-serve coffee maker is purely for its convenience and efficiency.

If speed and convenience are your main priorities, then single-serve brewing is the way to go for you. They’re perfect for an early-morning caffeine fix as you’re running out the door.

Keurig uses a pod-based design for its machines. This offers you an even quicker brewing time than other single-serve designs. Although it’s not a high-quality brew, the taste is good enough for an average cup of coffee. With a wide range of K-Cups supplied by Keurig to choose from, so you’re bound to find something that appeals to you.

When it comes to machine performance and coffee taste, there’s almost no difference between the K50 and the K55. Both machines produce pretty much the same coffee brew. The real difference between these machines is maintenance and appearance.

Both the K50 and K55 are quick and simple to use. When it comes to control panels, the K55 and K50 are also identical in this category. They each feature only a power button, three buttons for size options, and an auto-off button. This simple design is perfect for both after a super easy-to-use design.

The two machines brew your coffee at a temperature of roughly 195°F.

Your entire coffee brewing process will be pretty much the same for these two models.

Both offer a convenient auto-shutoff feature, so you don’t have to remember to turn it off on time if you’re in a rush. This is another favorite feature of ours, which makes the machine so reliable for every-day use.

Another shared downside is that these machines don’t allow for any customization. The brew strength, temperature, or pressure of the brewing process are set. This results in weak brews, but these machines will still get the job done in covering your basic caffeine needs.

When it comes to capacity, these two come in a solid tie. They both have water tanks with capacities of 48 oz. and offer the same cup size in coffee brew serving.

We know that cleaning is any caffeine lover’s nightmare, but Keurig machines are pretty easy in this department. The cleaning and maintenance requirements of these machines are pretty much identical. The only difference is that the K55 offers useful reminders and a descaling feature.

While neither the K50 nor the K55 is able to produce a latte or cappuccino, they are both capable of making tea, hot water, and iced coffee.

As you can see, these Keurig machines are extremely similar.

If you’re still unsure of which one to go for, then keep reading on. Next, we’ll break down the most important differences between these models to make your choice easier.

Keurig K50 Vs K55: Stand Out Features

Brewing Speed

Both the K50 and the K55 have an impressively fast brew time. Keurig’s marketing promise is that both models take under a minute to brew. But while the K55 can actually brew a cup in under a minute, the same can’t be said for the K50.

We found that the K50 actually took around a minute and a half for it to brew coffee. While this is still quick, it’s not a good look when a brand doesn’t live up to its marketing promises.

The K55 is definitely a winner here. Unlike its predecessor, it actually lives up to its promises.

Auto-Off Feature

Both models have auto shut-off features, but they have different shut-off times. The K50 will shut off after thirty minutes of inactivity, while the K55 shuts off after two hours.

The K55’s longer auto shut-off time is less energy efficient. This is something to consider when buying.

So, the Keurig K50 comes out on top here. It’ll save you a little energy and will be more environmentally-friendly in the long run.


Both Keurig models aren’t the best quality machines on the market by a long shot, but the K55 takes the lead here.

Although both models are made out of plastic parts, the K55 tends to outlast the K50 by far. The K50 is more prone to performance issues, breaking down, and bad customer reviews in general.

Descale Feature

Another excellent upgrade of the K55 machine is its auto-descaling feature, which is lacking in the K50 model.

Descaling is a very effective cleaning process for your machine. Using the descale feature, you are able to run a descaling solution and water through your machine. This makes a huge difference in the machine’s maintenance and also contributes to its reliability.


The K55 features a useful maintenance reminder -so you won’t forget to clean it!

The light goes on to let you know when it’s time to descale your coffee machine. This reminder goes a long way in preserving both your machine and the taste of your coffee brews. 

The K50 lacks this handy maintenance feature, giving the K55 another huge advantage.

Water Filter

The right water quality is an essential part of a decent cup of coffee. Here, the K55 is also a winner.

Featuring two water filters, the K55 brews a cleaner and smoother coffee taste. While the K50 relies only on a mesh filter, the newer K55 model is also compatible with Keurig’s amazing activated charcoal filters.

An activated charcoal filter a great addition that prolongs and enhances the quality of your brew. You also won’t need to replace it as often as the K50’s filter.

The water quality used by the K55 is better, which generally means your coffee will come out tasting better.

Compact Build

The slight difference in size and weight gives the K50 an advantage when it comes to compatibility.

This comes in handy if you’re stretched for space in your kitchen or office space. Plus, this makes the K50 a bit easier to transport.


The K50 and K55 models look almost identical. We think the K55 has a more elegant design, with smoother corners that give it a more compact look.

The K55 is also available in a range of colors including white and rhubarb, compared to just the classic black.


Keurig began phasing out the K50 model. This means that it’s becoming more and more difficult to find both online and in-store. Yet another reason to go for the K55 model!

Our Final Verdict

In a nutshell, the K-55 is by far the superior of these two choices.

Honestly, the K50 isn’t even worth looking into as an option at this point due to how outdated and unreliable it is.

While it might have been a leader in the single-serve brewing industry at one point, it has certainly been overtaken by its K55 successor that both lasts longer and looks better.

Use a Keurig K55 coffee maker if:

  • You are looking for a decent single-serve coffee machine
  • You want a machine with a few added features for extra convenience
  • You are looking for a trustworthy coffee maker with better customer reviews

With its brewing time of under a minute, the K55 model is the perfect machine for you if you’re looking for a basic, easy-to-use, and efficient single-serve brewer.

Use a Keurig K50 coffee maker if:

  • You are on a very tight budget
  • You are prepared to deal with your machine possibly not lasting a long time
  • You want a slightly smaller, lighter machine

Although we wouldn’t really recommend the K50 to anyone, it might appeal to you if you’re looking for a more compact and cheaper model.

So there you have it, folks! The Keurig K55 is sure to meet your needs if all you’re after is a quick caffeine-fix.
