With more than 50 models of coffee makers under the Keurig brand, coffee aficionados will be spoilt for choice. However, the larger number of models can also make shopping for a Keurig coffee maker a nightmare.

One of the hardest decisions that coffee makers that love Keurig machines find almost difficult to make is whether to go for the K50 or K55 coffee maker models.

In appearance, the two coffee makers are almost identical, and given the model number one cannot help but assume the K55 is an improvement of the K50. This might be true but still not enough to make the choice easier.

Understanding what actually sets the two amazing coffee makers apart is the only way to ensure you make a more informed decision. Our side by side comparison of K50 and K55 below should shed more light on how the coffee makers differ.

Keurig K50 vs. K55

Given that the K55 is an improvement of the K50, the differences between the two should be obvious but this is hardly the case.

The two coffees makers have similar dimensions and the same brew sizes given that they both make 6, 8 and 10 oz cups of coffee and in under one minute. Also, the two coffee makers have a 48-ounce water reservoir and a convenient auto on/off function.

But despite the many similarities, the two coffee makers will also differ in several aspects that should help you make up your mind.

Key Differences

Keurig K50 and K55 are identical in appearance, and it is hard to tell them apart at first glance. But, they are still two different coffee makers that differ in the following ways.

1. Filter Type Used

Filters are vital for any coffee maker as they ensure the water that ends up in your coffee is great quality for a great tasting cup of coffee.

The type of filter used on these machines is one of their main points of departures given that the older model which is K50 has a simple mesh filter which might be reusable but will still need replacement at some point and is also not useful for cleaning water.

With the K55, on the other hand, you get activated carbon filters that will tap most contaminants to ensure your coffee is brewed with the cleanest water for a smooth and great tasting cup of coffee.

2. Ease of Cleaning and Maintenance

Both the K50 and K55 will need cleanup after every use and some regular thorough cleaning to ensure your coffee maintains a good taste.

Generally, cleaning and maintaining these coffee makers is quite straightforward for both machines and the process is identical. However, the K55 is more likely to give you a much easier time than the K50.

What makes the K55 easier to clean is that it has an automatic descaling function which is missing on the K50. With the descaling function, you only need to push a button to clean up the machine thoroughly.

Descaling should also not be hard for those that use the K50 given that you only need to add the descaling solution and follow the same process as brewing coffee.

3. Brewing Noise Levels

Both Keurig K50 and K55 will still produce some noise when making coffee but the level of noise the machines produce differs.

Because the K55 uses a Quiet Brew Technology, it will be a relatively quieter machine than the K50 which many coffee drinkers find annoyingly noisy.

While the K55 might be relatively quieter than the K50, the noise levels on both coffee makers are still quite high, but this is typical of most coffee makers in their price range.

4. Difference in Weight

Keurig K55 weighs around 12 pounds while the K50 weighs about 7.6 pounds which is quite a huge difference given that the coffee makers are almost identical in appearance.

The extra pounds on the K55 are from the fact that it is an improved version of the K50 with better and more internal components.

Also, the plastic used on the K55 feels a little thicker than what is on the K50, and so it is probably a greater gauge which adds to the weight of the coffee maker.

But, both coffee makers are still quite compact and lightweight when compared to other similar ones from other models. Hence, both K55 and K50 will still take up little counter space and handling or moving them should not take a lot of effort.

5. The Price

Since the K55 is an improvement of the K50, one would rightfully expect it to cost way more than the latter but this is not the case.

In most popular online retail stores, K55 is also marginally pricier than the K50. In some stores, the K50 is even more expensive than the K55, and so price should not be a significant concern when picking between the two. And this is more so given that both are budget coffee makers.

Which One Should You Go for?

Neither the Keurig K55 nor the K50 has the bells and whistles of a high-end coffee maker such as LED displays and temperature/pressure controls, but they are still top notch coffee makers that will make great tasting coffee and are quite versatile.

Given the simple button controls on the two coffee makers, it is hard to mess up things when brewing coffee, and both will also have an auto-off function.

But, despite the many similarities, which machine will be better for you? The answer depends on your personal preferences and how much money you are willing to spend.

However, given that K50 has a history of breaking down, the K55 is generally the better machine for you. And this is because it was manufactured to specifically address the shortcomings of the K50.

The K55 is a versatile coffee maker with reliable and updated features and relatively quieter operation, and in some retail stores, it is even cheaper than the K50.

The bottom line is that unless the K50 holds some sentimental value to you or have used it for some time and just love it, the K55 is the best machine among the two given that it is an updated version.
