Is Keurig K-Duo for You?

 A complete package for a basic brewer is what Keurig k-Slim owns. Its accessible and quality features and specs make you realize this is what you need. But we should not directly run down to the conclusions; let’s compare this brewer with a few other Keurig brewers to clear out the “Is for you” doubt.

Keurig k-slim and Keurig k-express are both known for their skinny body and counter-space-saving feature. The difference between both brewers is water reservoir capacity. K-slim has a 46 oz capacity, while express has a little less than 42 oz. A strong button for intenser coffee resides in the K-Express version. Multiple stream technology is part of k-Slim. With the drip tray removed, a Travel mug of 7″ tall can accommodate in k-Slim while 7.4″ tall in k-express. For similarities, both brew 3 brew cup sizes; 8, 10, or 12oz. The water reservoir is attached at the back of the brewer of both models. 

The Keurig k-slim and Keurig k-Compact differ starting with the water reservoir capacity. About 46 oz of water is stored in k-Slim and 36 oz in k-Compact. Their brew cup sizes vary as 8, 10, or 12 oz are there for k-Slim and k-Compact; however, k-compact has an additional 6 oz size. For similarity, both are compatible with brewing from k-cup pods and my k-cup ( for ground coffee). Both models’ drip trays and reservoirs are removable and have an electricity-conservative ability. 

Mini plus coffee maker water reservoir capacity is low at about 12 oz because you have to fill the reservoir every time before use. This case is not with the k-slim due to its large capacity of 46 oz. K-mini plus has a variety of brew sizes; 4, 6, 8, 10, or 12 oz, which is relatively more than the k-slim; 8, 10, or 12 oz. K-mini plus can accommodate travel mugs up to 7″ tall. Both k-slim and k-mini plus has a removable water reservoir for easy refilling. Another feature that separates the k-slim from k-mini plus is; that the k-mini plus has pod storage that can store 9 pods for instant availability for brewing. K-slim doesn’t have this.

After learning the difference and similarities between Keurig k-slim, k-compact, and k-mini Plus, let’s distinguish which is suitable for you.

  • Keurig k-Slim will be a good choice if you want a space-friendly, basic simple brewer with high-quality and full-flavor coffee taste within a few minutes.
  • Keurig k-Express can brew cup sizes of 8, 10, or 12oz, has a 42 oz reservoir capacity, brew rich flavor coffee, accommodate a 7.4″ tall travel mug, removable drip tray, and water reservoir, and has a small footprint. A perfect match for the basic coffee lover.
  • Keurig k-Compact serves a large water reservoir, multiple brew-size cups, auto-off, removable drip tray and reservoir, and descaling indicators. If these are getting your attention, then why not get Keurig k-Slim?
  • Keurig k-mini Plus’s plus point is that it can store up to 9 pods in it for on-the-spot availability but has low water storage capacity. Refilling requires every time before brewing. Nevertheless, it has a lot of options to choose from when it comes to brewing cup size; for instance, 4, 6, 8, 10, or 12 oz are there for choosing. If you are okay with the refiling, then all these specs are bright spots for you.
