But they are a bit older. If you were to vs the Keurig K55 and K45 against newer models, you would find that these two older machines lack a few features. But that doesn’t mean they aren’t great quality! They still have a huge water reservoir, they still make delicious coffee, and they are still relevant even in today’s market.

What can you expect from the Keurig K45 and Keurig K55? Well, you can expect yummy single-serve coffee, a removable drip tray, a useful water reservoir, a sleek design, an easy user interface, simplistic button action, and a coffee maker that will last you for years to come.

While there are a few differences between the Keurig K45 and the Keurig K55 – which we will discuss shortly, there are mainly similarities. The K45 is truly the original Keurig coffee maker, while the Keurig K55 is a slightly more advanced upgrade without any huge or impressive features. But both models are a great choice for adding a coffee maker station to your kitchen! Who doesn’t love a great cup of coffee at the push of a button?

The Difference Between Keurig K45 and K55

Keurig Differences

To give you a simple breakdown of the K45 and K55, they are the same machine. The K55 is simply the upgraded version of the original Keurig K45 coffee maker. The K55 does not offer any new features, any new capabilities, or any new revolutionary ways of making coffee. These are for all intents and purposes, the exact same coffee maker.

But there is one major difference. The Keurig K55 is significantly improved in its functions. What happened was that Keurig went back with their K45 model, fixed all the bugs and all the things that weren’t working the way they wanted, and they released the new machine as the Keurig K55.

What this means is that you get the same cup of coffee, the same exact features, the same look, the same style, but an upgraded performance. The K55 is superior only in the fact that it works better and will probably last longer.

Additionally, the K45 only comes in black, while the K55 comes in black or red. And besides that, you might have a hard time finding a K45 because it has been discontinued. They don’t make these models anymore, so if you do find one it has probably been used. The Keurig K55 has not been discontinued by the manufacturer, meaning it’s still available for purchase just like any other coffee machine.

Keurig K55

Keurig K-Classic

This is arguably the best machine ever designed by Keurig. It’s simply amazing. It’s packed with all that you need for a rewarding coffee experience at an affordable price. It’s one of the older models, but that doesn’t make it any less of an amazing coffee maker that belongs in the center of your kitchen counter for years to come!

Features: You get to choose your size of coffee, you get a large 48-oz water reservoir, and you have multiple colors to choose from! Instant coffee, desirable flavor, automatic shutoff, simplistic design, auto-descaling mode, and full access to all Keurig K-Cups.

Ease of Use: This is one of the easiest coffee machines in the world to operate. It has just a few buttons on the front, including a power button and three choices for the size of your brew. Simply select from the clearly labeled options and enjoy your coffee a few seconds later!

Brew Quality: The quality of the brew with this machine is phenomenal. They really learned their lessons from the previous model and upgraded everything to give you a smoother and more refined coffee taste with every cup. No more coffee that tastes like water!

Cleaning & Maintenance: The machine is also super easy to clean with a rag and a bit of water. And it comes with a special descaling feature which is critical to help remove the deposits of calcium that build up overtime inside of your coffee maker. By using the descaling feature, you can clean the machine in just a few minutes without much work.

And if you want to be conscious of the environment, this is one of the coffee makers that is compatible with the My K-Cup Reusable Coffee Filters.

    Keurig K45 (Discontinued)

    Keurig K45

    Yes, the K45 is indeed discontinued. But this was the original Keurig Classic and it still works even today. You probably won’t be able to find a new one anywhere for a reasonable price, but if you can, definitely don’t hesitate. Even after all this time and all these upgrades, the K45 still stands up as an amazing machine.

    Features: You get a large 48oz water tank, a removable drip tray, multiple brew sizes, easy control with the simple buttons, the availability to use all the K-Cups on the market, and your coffee can brew in less than a minute! This thing is endless when it comes to features. There are indicator lights, the design is sleek and compact, and it’s a very reliable unit.

    Ease of Use: The K45 is super easy to use. Simply pop the pod of your choice into the basket, close the lid, hit the brew button, and you’re off to the races! There is literally nothing more to it. For an in-house coffee system, it doesn’t get any easier than this. Even a baby could do it!

    Brew Quality: The quality of the coffee here is OK. Remember this was one of the original machines designed and distributed by Keurig, so the flavor isn’t quite perfected yet. When it comes to K45 vs K55, the latter is definitely the winner for brew quality.

    Cleaning & Maintenance: Cleaning and maintenance has never been easier. The unit comes included with the charcoal filter and a water filter handle, which seriously help when it’s time to clean up. The water reservoir is removable and can be washed by hand in just a few seconds. The removable drip tray is also easy to clean.
