The button can also select the size of the cup of coffee, from 6 ounces to 12 ounces. The button is clearly labeled and easy to use.

Both models also feature a light indicator to tell you when the machine is on and ready to brew.

The K Slim has a removable 46-ounce water reservoir, compared to the K Mini’s 12-ounce single-cup reservoir, making it much easier to brew larger batches of coffee.

In addition to this, the reservoir on the K Mini is not removable as the K Slim.

In addition, the K Slim further enhances this feature with its multi-cup reservoir and multiple brew sizes.

Keurig K Slim vs. K Mini: Brew Quality

The Keurig K Slim has a clear edge over the K Mini in terms of brewing quality, mainly because of its Multistream technology.

This unique technology distributes the water stream across the coffee ground surface for a more even saturation and a richer, fuller flavor.

Plus, it’s easy to use and clean, making it an excellent choice for busy households.

The Keurig K Mini can still make a delicious cup of coffee.

However, it won’t be as effortless as using the Keurig K Slim due to its more well-rounded features.

The Keurig K Slim and K Mini are easy to clean and maintain.

The removable drip tray makes cleaning off accidental spills and overflows easy.

This feature is also helpful for travel mugs, as it creates extra clearance for larger cups.

To clean the exterior of the machines, a damp cloth should be used to wipe away any dirt or residue.

It is essential to avoid using abrasive materials or liquids as this could damage the exterior of the machines. 

Furthermore, regularly descaling your machine is vital to keep it running efficiently.

This will help keep it running smoothly and ensure you get the best cup of coffee every time.

The K Slim has additional features, such as multistream technology and a larger water reservoir.

However, both models are great options for those who want great-tasting coffee in a small package.

The Keurig K Slim offers more features than the Keurig K Mini.

The K Slim has advanced features such as a multi-cup reservoir, multiple brew sizes, and multistream technology, which the K Mini does not have. 

The K Mini is perfect for those looking for something simple and economical to fit in their small kitchen or countertop.

It is only a few inches wide, making it the ideal solution for cramped spaces. 

Ultimately, we love both coffee makers, and you won’t be disappointed with whichever one of the machines you decide to buy!


Do The Keurig K Slim and Mini Use The Same Pods?

Yes, the Keurig K Mini and K Slim both use the same pods.

Both machines are compatible with other cups and pods, not just Keurig-licensed cups.

This means you can use regular K cups, reusable K cups, and other cups and pods with these models. 

What Are The Best Alternatives To The Keurig K Slim And K Mini?

The K-Slim and K-Mini are both great entry-level Keurig machines, but if you’re looking for something better, there are a few alternatives that offer more features and better coffee.

The K-Express is an excellent option if you’re looking for an inexpensive machine that still makes great coffee, and the K-Compact is a good choice if you need a small and compact device that can still hold 3-4 cups of water in its reservoir.

Another option would be the K-Select, a slightly more expensive machine with more programmable settings that can produce a more flavorful cup of coffee.

Does The Keurig K Slim Or K Mini Make Better Coffee?

The K-Mini Plus offers the best-tasting coffee of the three machines due to its “Strong” button, which slows down the water flow through the k-cup, giving you a more complete flavor extraction.

This setting will also brew your coffee slightly slower, but most people won’t notice the extra 20 seconds of wait time.

On the other hand, the K-Slim does not offer a strong button and therefore does not produce the same quality of coffee as the K-Mini Plus.

The K-Slim is limited to 8, 10, or 12oz of water from its water tank and does not produce a full-flavored cup compared to the K-Mini Plus.

Does The Keurig K Slim Or K Mini Have Water Filters?

The Keurig K Mini and K Slim do not have water filters.

However, an easy way around this is to simply use filtered water instead.

What Are The Brew Times Of The Keurig K Slim And K Mini?

The Keurig K Slim is much faster than the K Mini in brewing.

The K Slim can brew a cup of coffee in just over 30 seconds from the moment you press the brew button, while the K Mini takes about 45 seconds.

If you’re using a K Mini Plus, you can press the brew button, which will make the brew longer.

However, you will get a better-tasting cup of coffee. 

Which Is The Best Between The K Slim, K Mini, And K Mini Plus?

The K-Mini Plus offers the best overall experience regarding brewing coffee with a Keurig K-Cup machine.

While the K-Slim and the base model K-Mini offer entry-level performance, the K-Mini Plus provides a “Strong” button that slows the brewing process down so that the brewed coffee tastes better.

It also provides multiple brewing sizes in 6, 8,10, and 12 ounces.
