Keurig Slim vs Mini (2021): Choosing Space-Saving K-Cup Coffee Makers

For many, Keurig is their go-to choice for a convenient, easy-to-use coffee maker. However, it’s become quite a task to choose, considering the many options available nowadays. 

One of the most popular models is the Slim, which was designed with space saving in mind, but the cheaper Mini has got it beat in that regard. Between them, there’s more to it than size, though. At that, we compare the two to help you decide.

Design

The Keurig Mini is smaller and has more color options than the Slim.

The Keurig Mini (in photo) is your best bet if you don’t have that much space in the kitchen.

Right off the bat, the two share a compact design that’s made to fit even in the smallest kitchen. The Keurig Slim measures 4.7” x 12.1” x 15.2” (width, height, and depth, respectively) and weighs 6.2 lbs, while the Mini measures 4.5” x 12.1” x 11.3” and weighs 4.6 lbs. The takeaway here is the latter has a slightly smaller form factor and is more lightweight, making it easier to bring along with you on trips.

Speaking of finding a spot in the kitchen, the Mini is more flexible in blending right in with the decor since it comes in a wide variety of colors: Matte Black, Poppy Red, Studio Gray, Oasis, and Dusty Rose. Meanwhile, the Slim is available only in black and white.

Both have removable drip trays, and thanks to that, they can accommodate travel mugs of up to seven inches.

Performance

The Keurig Slim has a bigger water reservoir than the Mini.

Of the two, only the Keurig Slim gives you the option to make 8, 10, or 12 oz cups of coffee. Its reservoir can hold up to 46 oz of water, and you can brew multiple times before you need to refill it, which is perfect for when you have guests over. In contrast, the Mini will use up all the water in it for each brew, and the serving size will depend on how much is in the reservoir, which can range from 6 to 12 oz. Just to be clear, you’ll have to add water each time you make a cup of joe.

Additionally, the Slim’s reservoir is removable for easier cleanup and compatible with a water filter, specifically the Tall Handle Water Filter. On the other hand, the Mini’s reservoir can’t be removed, and you’ll have to make do with wiping it down with a lint-free cloth to clean it. Moreover, it can’t fit any of Keurig’s water filters.

Expanding more on maintenance, only the Slim has a dedicated Descale indicator light to remind you if it needs to be descaled. But it isn’t much of an advantage since you can keep the Mini in tip-top shape by simply being a bit more mindful.

Both have an auto-off function, but while the Slim shuts off after five minutes, the Mini powers down after only 90 seconds, making it more energy saving. Also, the two are compatible with the My K-Cup Universal Reusable Coffee Filter, so you can use your own coffee grounds instead of K-Cups.

Options

The Keurig Mini is more affordable than the Slim, which costs almost the same as the Mini Plus.

The biggest advantage the Keurig Mini has over the Slim is its lower price tag, but as noted, the trade-off is it has fewer features. However, that’s where its beefier sibling the Mini Plus comes in. 

On that note, the Mini Plus is priced slightly less than the Slim, but it’s comparable in terms of features. It has a removable water reservoir and an included pod storage that holds up to nine cups. To top it all off, it even has something the Slim doesn’t have: a strong brew option. For those who don’t know, it takes more time to brew, but the result is a stronger and more intense cup.

Verdict

The Keurig Slim can just offer more than what the Mini can.

The Keurig Mini is hard to recommend when the Slim is readily available, and that’s not even considering the Mini Plus. Sure, it may have a smaller size, more color options, and a lower price, but those aren’t enough to tilt the scales to its favor. After all, the Slim has a water reservoir that’s not only larger but also removable, so it’s easier to clean. It also has serving options, and while this is far from its main selling point, the Descale indicator light can come in handy in maintaining the coffee maker.
