Quick Review

Looking over the product specs, we can see that the Keurig K-Slim and the Keurig K-Mini have a lot in common.


How do the products stand individually? Here is a short review of both coffee makers, starting with the Keurig K-Slim.

Keurig K-Slim (Rating: 85 %)


The Keurig K-Slim is an entry level brewer. It was designed to satisfy everyday coffee needs and with a form factor that takes little to no space on the average countertop.

Taking things one step further, the Keurig K-Slim is outfitted with a 46oz water reservoir that can handle four 8oz brew cycles without needing a refill.

In fact:

The coffee maker can cycle between the 8oz, 10oz and 12oz brew sizes to fit your mood and craving for coffee.

It’s an an excellent choice for those who brew multiple cups of coffee per session. It also works well when paired with a variety of K-cup flavors as opposed to pricy coffee beans.


The K-Slim does what it does best which is offer simple brew coffee, and a lot of it.


We would be remiss if we didn’t address the high price point. The K-Slim is priced quite steeply and doesn’t come equipped with temperature or other intricate control features.


While it does have a high altitude brew setting, and multistream technology, it doesn’t have a display or any other capabilities to warrant the high price point.

Keurig K-Mini (Rating: 81.6%)


The Keurig K-Mini is marketed as the most space effective Keurig coffee maker, as opposed to the K-Slim.

The brewer is also a model in simplicity, able to brew a single cup of coffee with each fill of the reservoir.

Keep in mind:

The K-Mini is made from planet-conscious materials and recycled plastic. It is very light and fits just about anywhere in your kitchen.

It is the perfect coffee maker for those who enjoy simplicity. What’s more, the auto-off feature, which shuts down the brewer when it is inactive is an added bonus.


 it may not meet your needs if you say, want to make a cup of latte or any other type of coffee.

The Keurig K-Mini also doesn’t use multistream technology, and therefore isn’t the most efficient brewer on the market.


The Keurig K-Mini comes with a much smaller water reservoir compared to the K-Slim. This reservoir isn’t detachable, making the K-Mini a lot harder to maintain and use.

CoffeeHolli’s Recommendation: Which One Should You Buy?

After looking through the functionality of both brewers, I’ve seen that they are very similar. You see, both the K-Slim and K-Mini were designed to be space efficient.


They are both simple brewers with limited functionality and settings, save for the high-altitude brew setting on the K-Slim.


The question remains- which one should you get?


I think the Keurig K-Slim stands out due to its larger water reservoir. It can handle three to four brews on one reservoir as opposed to the single-cup brew of the K-Mini.

On the other hand:

The Keurig K-Mini is much more cost-effective, offering a lot of the same features as the K-Slim in a smaller form factor.


I believe the Keurig K-Mini is the better purchase. It may be a little more tedious to maintain, but it does come equipped with all the necessary features for a simple brew.

From Experience:

The K-Mini is a reliable coffee maker. It’s a sturdy model that I take with me on long trips. It will serve you well.


I set out to answer one question when starting this guide….

Which is the better purchase? The Keurig K-Slim or the K-Mini?


We have seen good arguments for either option, but it may not be what you wanted to hear.


The K-Slim and the K-Mini are space-effective, simple coffee makers. They differ in reservoir size, detachability, and specific settings. The K-Slim is also a little more expensive.


Which is the right one for you? Is the high altitude brew feature on the K-Slim worth the extra 40$? Or is the K-Mini just right to fit your kitchen space and early morning synergy?


Hopefully, this guide has offered all the information you need to make an informed decision.
