Keurig K50 VS K55 – What’s really different, and should you care?


Keurig models offer the best and most convenient coffee brewing experience. They will often be the go-to coffee maker for your local bank where you can make yourself a cup while they make you wait. Keurig coffee makers are quite affordable for home use too, and the K50 and K55 can both be available for $100, even. Definitely cheaper than a home espresso machine, which will likely be of much lower quality anyway.

When we got to comparing the Keurig K50 and the K55, we took into consideration a few factors, including coffee quality, convenience, design, usability, durability, and even customer reviews. If you’re not a new coffee machine user, you probably know that other people’s experience with a certain brewer model can make quite a bit of a difference as to whether that is a good investment or not. A cup of coffee is a cup of coffee, after all, but why not get the best one there is?

Without further review, let’s get talking about these two excellent coffee makers. Our overall verdict is in the chart below if you would rather just get this over with. However, if this information doesn’t satisfy you, then please do continue reading.

Difference and similarities between these two Keurig home brewing systems

Okay, so first of all, these are both excellent coffee makers, no doubt about it. The Keurig K55 is a newer, upgraded model and is generally supposed to be more durable and convenient, although not everyone would agree with this statement. Regardless, both our and most users’ experience with these two Keurigs is that the K55 is indeed the preferred option. Let’s see why.


The installation process is pretty simple for these brewers: you unbox them, plug them in, put some water and a K-cup in, push the Brew button, and you’re good to go. That’s literally it. There is a user manual with both, but I don’t think you’ll ever need it.

Other than that, f you’ve ever used a Keurig model before, you probably know they there really isn’t much to say about their usability. They have the standard buttons which let you pick the amount of water added, can be programmed to turn on or off at a set time, and have K-cup pods – that’s really about it. One thing about the K55 that the K50 doesn’t offer is the option to use water filters, and the K-Classic comes with two water filters (and a handle).

While Keurig claims that both of these are supposed to brew a cup in under a minute, you can’t know for sure until you see it yourself, which we did. Turns out, that was, in fact, the case with the K55, but not so much with the K50, which took almost a minute and a half. While not much, some people are busier than others, and it can add up.

The convenience of the Keurig K50 and Keurig K55 single-serve models

Nothing beats Keurig when it comes to convenience though, so as long as you have a K-cup laying around you can brew anything with the push of a button. Just have your water reservoir (and entire brewer, preferably) clean and full with water (that is WATER, not milk or any other liquid), have the K-cup inserted in the middle of the brewer, and pick your poison. If you’ve just started the brewer, make sure you do a “cleansing brew” first before using it – the same process, without the K-cup; you just need a little water brewed and out inside a cup.


96 Count Variety K-cupsAs for K-cups, there are plenty of options and tons of tasty ones! I literally prefer a cappuccino from a K-cup rather than an actual cappuccino machine. That might just be me, but there is something about the large variety of options and their affordability that makes these brewers exciting! You can even order these online in a large variety of packs. Just PLEASE don’t be one of those people who take the lid of the K-cups. Please.


Both of these look pretty sleek, and will likely fit your kitchen as much as any modern-looking appliance would or could.

Color Options The two color options of the Keurig K50 and K55 – jet black and rhubarb

Color options are pretty limited when compared to other Keurig models, and both are available in jet black and rhubarb color, with the K55 also having a full white version. The white definitely isn’t my personal favorite, since it just doesn’t really strike me like the best color for a coffee maker, but that might be just me.

The K55 does have smoother buttons and it feels a bit nicer overall, although the difference isn’t that noticeable. It can make the overall usage experience a little more pleasant though, which, after all, can make a difference if you pay attention to details and the small things in life.

Built and durability

I now use the Keurig K55 and while it’s too soon to tell, this coffee brewer does feel more durable than the K50. The K55 weights just under 15lbs, compared to the K50’s eight pounds, meaning that it’s overall heavier, while it also feels like it has less plastic. I haven’t taken it apart yet, but the K55 doesn’t have that “plastic” coffee taste that is often mentioned to accompany cups brewed with the K50 in user reviews from around the Internet.

Other than that, both brewers have removable trays, obviously. They also both have the Keurig standard sized water reservoir, which can contain up to 48 ounces of liquid. This is more than enough for a home coffee machine of this class and anything larger would just be overdoing it.

The whole “feeling” of the K55, however, screams higher quality than the K50. It’s often just the small things about it really, but enough to make you wonder why they wouldn’t design the K50 to be (and appear) more durable in the first place.


This is one where the K55 certainly takes the gold home. My K50 used to have this thing when it would turn off all of a sudden. While still a great brewer and I try not to be much of a drama queen, I would lie if I said that this wasn’t annoying at times, in all honesty. The last thing you want is NOT to have a cup of coffee ready to go when you’re already late to the office for the day. Or if you’re making coffee for a few friends and then one of them doesn’t get a cup. Oops.

While this didn’t happen that often with the Keurig K50 vs the K55, I’m not the only one it has actually happened to. There are multiple online reviews of people claiming the exact same, if not worse. Sometimes it won’t even start back up, so you need to get repaired and all – might just be smarter to get a new one if you cannot be bothered, though. This doesn’t seem to be the case with the K55 and it looks like Keurig has fixed the problem with this model.

K50 vs K55 other features and differences

K55 White Version

As we already mentioned, the K55 comes with two water filters which you won’t find with the K50, which is a nice perk. Both coffee makers are quite easy to clean and saying that one is better than the other in this area would be foolish. They both can brew cups that are either 6, 8, or 10oz.

It might be important to note that the K50 is a little noisier, so if you would rather avoid hearing your coffee brewing, the K55 stays the better option. I don’t really like the sound of coffee brewers in general (I know, weird me), so the quieter they stay, they better.

Aside from the plastic coffee taste problem with the K50, the K55 can also brew a stronger coffee, if you’re a caffeine junkie like me. You may not want to take advantage of this option if you’re already on your sixth cup for the day, though.

Both brewers have no temperature of pressure control, which is obviously expected from a Keurig machine in this price range. If you’re looking for a coffee maker with temperature control, you might want to check out the Keurig K575 instead – while more expensive, it is a higher-end model that beats both the K50 and K55.

So, should you go with the K50 or K55?

It’s really up to you, but as we’ve already said, the K55 is indeed an upgraded model that has a couple of better options and a few issues fixed. Not many other improvements in terms of design and usability, which may, in fact, be a good thing. After all, why fix something if there is nothing to fix? The best of best Keurig choice is the K475 or K575 machines however the K50 and K55 are great choices too.

The thing about the K55 is that with all the flaws of the K50 model, it indeed is the coffee lover’s choice. No plastic taste doesn’t break down in the middle of usage (on multiple occasions), brews a cup slightly faster and looks just a tiny bit better. Look at it as if you were to compare an iPhone X to an iPhone 8s – not a whole lot has changed, but it is the newer model, after all! This should settle the Keurig K50 vs K55 debate 🙂
