Difference Between KEURIG K50 And K55

A quick overview of K50 and K55 indicates that both are very similar to each other. But, the question, what’s the difference between Keurig k50 and k55, may make the buying decision hard for you Knowing all the differences will help you find the best machine to have a hot sip of coffee in the morning. Let’s see the difference between Keurig k50 and k55.

  • Speed

Just imagine you wake up in the morning and need a cup of coffee to start your day. But, what you’ve to suffer is your coffee machine brewing the coffee very slowly. It’s where the performance and speed of the coffee maker matter a lot. 

You might be wondering how to know the speed of a coffee machine. Well, you have to note the time from the point when you turn on the machine to the moment when you have a hot coffee mug in your hand. The time your coffee machine takes in the process decides its speed. Less the time a coffee maker takes, the more speed it has. 

When it comes to K50 and K55, both are designed to be fast, effective, and simple. There is no much difference between Keurig k50 and k55 regarding speed. With K55, you can get the coffee mug in less than 1 minute. On the other hand, K50 can brew the coffee for you in 1-1.5 minutes. 

So, if you’re considering performance as a key point, K55 is the winner of the game. It’s faster than K50.

  • Custom Brewing Features

Both K50 and K55 use the same brewing technology. You will find three different brew sizes of 6, 8, and 10 oz in both models. And the amazing thing is that all the brew sizes are compatible with diverse numbers of K-cups. Either it’s a Keurig-licensed beverage producer or any third-party pod; you can use it with both of them.

Both of them have a K-cup holder to hold the K-cup. While brewing, hot water is passed through the punctured pod. Additionally, both these coffee makers brew at 192.2F to provide you with a tasty cup of coffee. This temperature is perfect as it’s found that coffee makers that brew at 200 degrees brew a strong cup of coffee.  

The only difference between both of them is the strong brew feature in K50. By pressing this button, you can get a stronger and bolder cup of coffee. So, if you often crave extra caffeine, consider the K50. 

However, if you’re interested in having lattes or cappuccinos, consider all in one brewing system. It’s because both K50 and K55 don’t allow you to make these coffee styles. Moreover, look for the best espresso machine to have creamy espresso coffee. 

  • Water Filter

Water filters are something that’s the answer for what is the difference between Keurig k50 and k55. The K50 comes with simple mesh filters, which are reusable. These filters are not of good quality, and you may have to replace them soon. On the contrary, the K55 carries activated charcoal filters, which are much better than mesh filters. 


You may not find this feature essential. But what can be more important other than when you’re mixing only water coffee. Further, the K55 filters are supreme and help you to achieve a smoother cup of coffee. 

So, again Keurig K55 is the winner with a better filter. 

  • Taste

The taste is essential to distinguish one coffee maker from the other. While discussing the difference between k50 and k55 Keurig regarding taste, K55 was found to be the best.

The coffee produced by the K55 is tastier, smoother, and stronger. The reason is its charcoal-based filters. These filters remove any impurities in the water. As a result, you will get coffee with the purest water.

On the other hand, most users have complained about the plastic taste in the coffee brew by K50. So, the taste of coffee from K55 makes this coffee maker shine. 

  • Maintenance

Cleaning both K50 and K55 is very easy. You can easily detach the drip tray, K-cup holder, and water reservoir for cleaning. The amazing fact is that you will get detailed step-by-step instructions in the Keurig K series user’s guide. Moreover, this guide will also help you to attach all the parts again after cleaning. 

cleaning coffee maker

The difference between Keurig k50 and k55 concerning cleaning is a descaling option. But before discussing that, you must know what the descaling is. Well, it’s a process to clean the internal parts of the coffee makers from calcium deposits. It can decrease machine efficiency.

Keurig recommends descaling the coffee machines every 3-6 months. So, the Keurig K50 and K55 also need to descale after 3-6 months. However, this time to descaling also depends on the water you’re using. For instance, if you’re using hard water, it means scaling is rapid. And you need to descale the coffee machine frequently. 

The difference between k50 and k55 Keurig is that the K55 comes with auto descaling detection. So, it will let you know when you need to run the Keurig’s descaling option or vinegar through the machine. However, it’s not essential to clean the machine with vinegar. You can also clean your coffee machine without vinegar.

For K50, you can do descaling using the same methods. But, you’ve to figure out when your k50 needs descaling.

  • Aesthetics and build 

Aesthetic is not the primary concern for many people. On the other hand, some are conscious of having coffee machines complementing their kitchen décor.

Both K50 and K55 are aesthetically classy. They can enhance the fancy look of your kitchen. You would not notice much difference at first glance in them. However, the difference exists. 

The first difference between them is colour choice. You have limited colour choice for k50 as it’s available only in black colour. On the contrary, you can have K55 in white, black and red colour. Besides colour choice, the compact design of K55 with smoother edges gives it a modern classic look.

A slight difference in weight and size also exists between them. The K55 is larger as compared to K50. Moreover, the K55 is 12lb compared to the 7.6lb of the K50. According to Keurig, the advanced features of K55 are the reasons behind its larger size and more weight.

  • Durability and Reliability 

There is no difference between K50 and K55 regarding durability. Both are made up of reinforced plastic, enhancing shelf life. However, if you have not maintained your machine, it would have less life. And it’s not the fault of the coffee machine; it’s yours.

However, reliability is where K55 wins the game. Several k50 users have complained that their K55 has stopped working. Just imagine, you’re ready for the office, and your coffee machine ditched you. We know how frustrating it is. So, it’s better to go for K55. 

  • Usability

Have you ever messed up your coffee cup by pressing the wrong buttons? Well, it happens mostly with a machine having a complex control system. And we know how annoying it is. That’s why we’ve chosen the K50 and K55 because of their ease of use.

Both K50 and K55 are quick and simple to use. There is no complex control system like pressure control, temperature control, an LED screen. You can easily control both machines with just buttons.


When it comes to how to use the Keurig machine, it’s not a hard task. If you just have got the new machine, you have to perform a one-time setup before brewing your first mug of coffee. Follow these steps to learn how to use the Keurig for the first time. 

  • First of all, connect the machine to a grounded outlet
  • Place a 10 oz mug on the drip tray
  • Fill the water reservoir to its capacity
  • Power the machine on from the button
  • Allow the coffee maker to heat until the red LED light turns off
  • With an empty coffee pod holster, press the button for the smallest brew size
  • Dispose of the liquid into the sink. 
  • Repeat the same process as above to brew a cup of coffee. However, don’t forget to place your favourite coffee pod inside the holster. 
  • Press the holder and get ready to have a hot mug of coffee.

Moreover, both machines have auto-off functionality. This option allows the machines to shut off after 2 hours of last brewing. Thus, both these coffee machines will enable you to save energy as well as time. 

However, you have to use the coffee from them instantly after making it. It’s because these are not compatible with thermal Carafe. If you want to prepare the coffee for the entire day once, you can go for a coffee maker with a thermal Carafe

After similarities, it’s time to find the answer for what’s the difference between Keurig k50 and k55 regarding usability. Well, it’s a “Quiet-Brew tech” in K55. This technology aims at reducing the noise and bells produced by the machine. So, the Keurig K55 makes less noise than the K50. However, it’s a surprising fact that some people still find it noisy. 

  • Price

Your pocket always stays as a hurdle whenever you think of buying something advanced. Don’t worry; it would not be the case here. The K55 is a little bit more affordable than the K50. So, if you’re looking for the best coffee maker at a reasonable priceK55 is the right choice.
