Keurig K50 Vs K55 – Why Is Keurig K55 More Popular Than K50

If you are a cafephile, just like me, how can you imagine a productive day without a cup of coffee in the morning? The kick of caffeine makes our day lively. 

But for that, you need to buy coffee from a coffee shop or a coffee machine. Keurig K50 and Keurig K55 are quite popular if you just want a cup of coffee without cumbersome customizations. 

However, if you don’t go into deep details, you will find these two identical machines are twins with no differences. But there are some major changes between them. 

So, if you are having confusion choosing either of them, this K50 vs K55 review will drive them away. Anyway, before going deep into this article, let me clarify, I prefer K55 over K50. As for the reason, no more spoilers.

Keurig K50 vs K55 – Why is the Keurig K Classic K55 more popular?

The K50 and K55 have a lot of identical features and they are quite similar at a glance. But there are some minor (even big) changes that set them apart.

  • Although the K55 was built as a separate model, it is now widely known as an upgraded version of the K50 coffee maker.
  • It offers the same 3 cup size and 40 oz water reservoir as Keurig K50, but additionally compatible with Keurig’s charcoal water filters and has a handy flashlight to warn you when the water is not enough. 
  • Both K50 and K55 have auto-shut-off features, but K55 is more energy-efficient and automatic shut-off after 2 hours. 
  • The K55 will cost you some extra dollars, but it has a charcoal filter to create better and smoother coffee. 

In the end, although both K55 and K50 are like siblings of the same mother, there is still a gap between them. And, K55 is sure the winner here. So, I preferred it earlier. But, many users still love the Keurig K50 coffee maker.

What is the difference between Keurig K50 and K55?

What is the difference between Keurig K50 and K55

Keurig K50 and K55 are quite similar in many aspects, starting from looks to materials. But, there are some minor changes in the upgraded version of K50, Keurig K55. The noticeable change starts with active charcoal water filters. A handy flashlight to warn you is also newly added. Now, let’s know the other differences. 


When talking about performance, the first thing that comes to mind is speed. However, there are two types of speed. One is when taking the first coffee of the day and the other is with the second and third cup. Both speeds matter here as you will not drink many cups of coffee with these machines. K55 and K50 both take 4 to 5 minutes to warm up and provide you with your first cup of coffee. 

Later, it will take near 1 minute for K55 and 1.5 to 2 minutes for K50 to brew the second and third cup. Not a big difference. 

The outline of both machines is the same – simple design, no LCD, only a few buttons. Both provide hot coffee, brewing temperature up to 89°.

Taste And Quality

Finding out which one provides better taste was the most difficult thing among K50 and K55 as they both taste the same. Probably because both of them use K-cups, and the brewing method is the same.

However, after a couple of trials and errors, I found K55 brews slightly stronger coffee. As for pods, both are compatible with K-cups and unofficial cheap K-cups. 

The quality is fine. Both machines provide strong enough coffee to make your morning. And, with the wide range of pods, you won’t complain about not finding a suitable one. 


As usual, the cleaning process of both machines is identical. They both come with a Keurig user guide. Trust me, if it’s not for the K50 and K55 names written on the cover, you won’t be able to tell which one is for which. 

The cleaning is also quite simple. Same old method. However, the only difference is that the K55 has auto-descaling, while the K50 doesn’t. But, descaling is not rocket science, the same as brewing coffee. 


Because of their similarities, aesthetics are not that important. Nevertheless, people are curious about it. Both have the same dimensional size, 9.8 x 13 x 13.3 inches in LWH, which is a standard size. Suitable for your medium size countertop. 

Both come in two different colors. One is matte black, and the other is red(not abjectly red. Because of the low-quality materials, the red one looks cheap. Anyhow, you can’t expect more from this price range. 

They don’t have LCDs, controlled by buttons. But you won’t feel stingy with the buttons. All things together, the matte black one looks quite handsome on its own. 

What users saying about Keurig k classic K55 And K50

Users loved this coffee machine, you can say this by a glance at the rating on Amazon. Both machines are single-serve coffee machines and easy to use. Moreover, the pod system saves time from hassling with coffee beans and saves a lot of time. Also, save wasting excess coffee. 

So, these coffee machines are widely popular for home use. But, if you need over 2 or 3 cups of coffee per day, it won’t be beneficial for you. Without that, both machines, especially K55, provide a good value. All the features are top-notch. Materials are also durable. 

However, some users complain about getting a broken product or used one. So, be careful about that.
