The Keurig Mini K15 Review
Let’s take a deeper look into the K15 and figure out how this coffee machine performs, given is price.

We’ve broke it down to show you how it performs in a few areas, but you can also watch our reviewer Scott give his opinion on it here:
Customizability – 2.5/5
The Keurig K15 single serve coffee maker does exactly what it’s built for: brew one cup of coffee in under 2 minutes.
If that’s all you are expecting from your coffee brewer, then you won’t be disappointed and you should go for this budget-friendly model.
However, when it comes to customizing your brew, the Keurig K15 loses points because it undoubtedly offers fewer options compared to other Keurig machines (for example, it does not have a Strong Brew button nor temperature control, and it has fewer cup size options than most models).
Still, you can choose between a 6, 8 or 10 ounce cup of coffee as well as hundreds of types of K-Cups, meaning you can simply get different flavors by buying different capsules. It’s also compatible with the My K-Cup universal reusable coffee filter, which we strongly recommend that you buy instead of always relying on K-Cups, given their environmental footprint. (1)
…Refillable K-Cups are a more sustainable choice. They’re made out of steel or plastic, and cost just a few dollars each
‘Make Your Life Easier’ Features – 3/5
While the Keurig K15 might not be very customizable, it does come with a few handy features. First of all, it automatically shuts off after 90 seconds of inactivity, saving you energy and money. (2)
The practical cord storage adds to its portability, making it even easier to move around the house or take with you on holiday.
The K15 also has a removable drip tray that facilitates the cleaning process as well as allowing you to use taller mugs or travel mugs, and the K-Cup holder is also removable and easy to clean.
For us, it only loses two points because it lacks features (such as the auto turn on and Hot Water button, for example) that some other Keurig coffee machines offer. Because this machine won’t remind you when it’s time to descale it, you must remember to do it every 3 to 6 months, depending on the concentration of minerals in the water that you use. (3)
Water reservoir – 2/5
Unlike other Keurig coffee makers, the K15 single serve coffee brewer doesn’t come with a water tank that you can fill up on Monday and rely on for the rest of the week, but with a one-cup reservoir instead. While it’s as small as it can get, we think it deserves two stars instead of one because this small water reservoir does enhance its portability and ensures that you always use fresh water.
It also makes it very easy to choose the correct amount for your cup: there are 3 different size indicators to ensure that you are using enough water for the size of coffee you are going for, but there’s also a flashing button that lets you know if you need to add more. It lights up as soon as you turn on the power, to remind you that you must add the water before inserting the K-Cup.
Things we liked:
- Cute and compact design
- Fast and easy to use
- Energy-saving auto shutdown after 90 seconds
- Very affordable
Things we didn’t like:
- No control over brewing parameters
- Fewer cup size options than other Keurig brewers
- No water reservoir
Do not buy the k15 if…
You want to customize your brew more – The K15 is handy if you just want to press a button and have a single cup of coffee, but, if you’d rather be able to brew a stronger coffee, control the water temperature and have more cup sizes to choose from, you might want to look into the Keurig K-Elite or the K-Select instead.
Or if you want a machine that make cappuccinos and lattes, the Keurig K-Cafe may be a better choice. Learn more about this machine in our Keurig K-Cafe review.
You don’t want to fill up the reservoir every single time – If you’re not too fussed about customizing your cup of joe but you are a bit annoyed at the idea of having to fill up the reservoir before each brew, then this Keurig model is not for you. We think you’d be happier with the Keurig K55 Classic: while it still offers 3 brew sizes and is in a similar price range, it comes with a 48 ounce reservoir, meaning that you could have a 6 ounce cup of coffee a day for a week without having to refill it.
The K55 also has slightly similar features as that of its predecessor, the K50. You can learn more about the difference between these two models here.
You want a coffee maker that can fit in your bag – If you bumped into our Keurig Mini K15 review because you were looking for a portable single cup coffee maker and realized that it’s not as portable as you thought, you might want to check out our list of the best travel coffee makers (which you will actually be able to fit in your bag).
The Verdict: should you buy the K15?
This may not be what you want to hear: we don’t think that the K15 is one of Keurig’s best models. It doesn’t offer a lot of customizable features and many users have complained about the lukewarm coffee temperature and the fact that it doesn’t last very long after repeated use.
But… it’s an OK choice for those who value portability and just want to enjoy a quick cup of coffee every once in a while.
No, Keurig K15 does not have a water filter. Because of the nature of its single serve reservoir, it is not compatible with Keurig’s charcoal water filters either. We recommend using pre-filtered water when using this model.
Yes, the Keurig K15 coffee maker comes with a one-year warranty.
The smallest Keurig model is the K-Mini Single Serve Coffee Maker, measuring 12.1” H x 4.5” W x 11.3” D. However, the Keurig K15 is also one of the smallest models: while it’s wider than the K-Mini, it’s shorter and less deep (10.8” H x 6.9” W x 10.7” D).
