We will discuss the qualities and features of each machine, hopefully, it will help to consume your time and simplify your shopping experience.

#Performing Capacity:

Discussing the performance capabilities between K50 and K55 is the most important aspect of our comparison article.

If we compare Keurig K50 and K55, brewing speed would be mentioned first. K55 takes nearer 1 minute, whereas K50 takes about 1.15 minutes -not a huge difference.

Both have button controls, and the entire process for making a cup of coffee is the same. Brew temperature for both is 89°C.

Now we can look into their filters, and here we start seeing a difference. The older K50 has simple mesh reusable filters – these are not great quality and you will need to replace them sooner rather than later.

On the other hand the K55 has activated charcoal filters, which create a more supreme and smooth coffee. But for activating charcoal filters you need to add extra dollars and it’s totally up to you.

Both the machines have auto – switch off.

#Brew Quality:

At the beginning, when comparing the Keurig K50 vs K55 you will notice they have very similar brewing systems.

Both the brewers have large 48-ounce water reservoirs that can be filled with tap, spring, filtered or purified water. This means that you can brew 6,8 or 10-ounce cups before having to refill the water reservoir. An indicator light will remind you when it’s time for refilling.

The K55 boasts a smooth and tasty cup of coffee. This is in part because of the charcoal filtration system that helps to filter water by removing impurities.

As the Keurig K50 does not include this filtration system, purified water can help you achieve similar tasting coffee.

If you are unable to adjust pressure and temperature with the K50 and K55, you can adjust the strength of your coffee by decreasing the size cup you are brewing. A smaller cup will boost the flavor of the coffee.

In the reviews of Keurig K50, it is found that some customers have complained of a plastic taste in their brewed cup of coffee.  Some Coffee Dorks think that the K55 brewed a slightly stronger coffee.

But then again, this difference is very vague and both tastes almost identical, probably as both machines are K-Cup compatible and so the flavor is almost the same.

Another difference between Keurig 50 and 55 is the products’ longevity and reliability. Compared to the 10.6 pounds of K55, K50 is relatively lighter at 7.6 pounds. It’s also about 2 inches shorter than its brother, making it more compact. K55 has a relatively longer lifespan than K50.

In the reliable issue we can trust k55 than that of K50, according to some customer reviews, k50 can stop working after a few weeks of use.
