Keurig Slim: The Most Complete Review

Keurig offers a variety of different coffee makers, with some being more popular than others. One that is often overlooked, though, is the Keurig Slim. While it may not be as well-known as the Mini Plus or Mini, it is worth considering if you are looking for a good single cup coffee maker. In this review we’ll look at the strengths and weaknesses of this machine. We’ll also compare it to other similar models, so you can make an informed decision about whether or not it is the best choice for your home or office.

The Keurig Slim is perfect for small kitchens, dorm rooms, offices or anywhere else where space may be at a premium and you need something that won’t take up too much room on your countertop. It’s also great if you want something simple yet stylish to complement your kitchen decor—this machine is sleek and compact with its modern design, so it looks good wherever you put it! Who says functionality can’t be stylish? Ultimately, this model was designed with convenience in mind, so if convenience is what you’re looking.

Each pod has its own filter and water chamber, so there’s no need for a permanent filter. The machine has its own water reservoir that can hold anywhere between 6-12 cups of water at a time. This reservoir is refillable so you can make more than one cup at once. Some models allow you to set the amount of water per cup. The machine heats up the water and pushes it through the coffee pod into your mug in just seconds (depending on the size of your mug).

All you need to do is hit the button and wait for the deliciousness to flow! Now let’s get down to business: which Keurig model should you buy? There are several different Keurig models available today, but I’ll focus on my personal favorite: the Keurig Slim. I’ve been using.

Keurig Slim


The Keurig Slim’s compact size and sleek design make it a great addition to any kitchen decor, and its unique features are sure to impress even the most discerning coffee connoisseurs.

The Keurig Slim is an updated version of the Keurig K-Compact. It has a slimmer, more compact design and other features that make it a popular choice for coffee lovers. It is a single-serve brewer that can fit in almost any space and makes one cup of coffee at a time. The design of the machine is smaller than its predecessor but it still brews a full cup of coffee. The water tank holds 40 ounces of water and there is a drip tray to catch overflow. This machine comes in three colors—black, red, and white—all with black trim.

It is a single cup coffee maker that measures just 5″ wide, making it perfect for smaller kitchens where counter space is at a premium. It has all of the features you would expect from a Keurig brewer including: a removable drip tray, three programmable cup sizes (6 oz., 8 oz., and 10 oz.), an auto-shutoff feature after 2 hours of non-use, and an energy saver mode that turns off automatically when not in use for more than 2 hours. 


  • Cord Length: 30-inches
  • Reservoir Size: 46oz
  • Weight: 9 Pounds
  • Color: Black
  • Dimensions: 18 x 15 x 8 inches

Programming and Controls

The Keurig Slim is a no-frills Keurig model, which means it doesn’t come with a lot of bells and whistles. It has a start button, an auto-off button, and a descale indicator light. The auto-off feature can be set to turn off after two hours or four hours, so if you forget to turn the machine off manually, you don’t have to worry about wasting energy when you’re not using it. The descale indicator will light up when your machine needs to be cleaned in order to prevent mineral buildup.

This is the first thing you should do whenever the light turns on, since mineral buildup will reduce your machine’s brewing efficiency and force it to work harder than it needs to in order to make your coffee. For instructions on descaling your Keurig Slim, check out our how-to video here. Unlike other models such as the Plus series that come with temperature controls, brew size options, and strength controls, there are only three buttons on the Keurig Slim: one for power (on/off), one for auto-off timing (2 hours or 4 hours), and one for cleansing cycles. However, this simplicity makes the brewer very easy to use—there’s virtually no.

Versatility and Performance

The Keurig Slim offers all the benefits of a single-cup brewer with a few extra perks. The machine comes with a detachable water reservoir that holds 48 ounces of water. This makes it easy to fill the water for making several cups of coffee without having to keep refilling the reservoir every time you brew a cup.

Most Keurig models hold less than this, so if you’re someone who drinks multiple cups in a day or brews them relatively close together, you’ll appreciate this feature—it’s not just more convenient; it also saves time and energy, which translates into savings on your utility bill over time. Plus, the removable reservoir makes it easy to clean out mineral buildup that can form in hard water areas. The brewer is equipped with two cup height options: six inches and eight inches. This makes it easy to brew a variety of beverages like coffee, tea, hot chocolate, cider, and other drinks into either short or tall mugs.


The dimensions of the Keurig Slim are 7 1/2″ wide x 13 1/4″ deep x 10 1/4″ high, compared to the most popular model, the K55 with dimensions of 9″ wide x 12.5″ deep x 13″ high. This means it can fit into more spaces and will not take up as much counter space. The K15 brewer is also a compact brewer but doesn’t make coffee as quickly or have as many features as the Slim. The K15 is 4 1/2″ wide x 11 3/4″ deep x 10 5/8″ high.

Keurig Slim vs. Keurig K-Compact

The Keurig Slim is a new addition to the Keurig line, along with the popular K-Compact. Both of these models are designed to be space-savers, but they have some distinct differences that you should know about before purchasing. Here’s a breakdown of how they compare:

Size and Shape

The Keurig Slim is both slimmer and taller than the K-Compact. The Slim is 14″ tall, 5.25″ wide, and 11″ deep, while the K-Compact is 13.6″ tall, 10.7″ wide, and 9.8″ deep. The difference in width makes the K-Compact easier to place on narrow countertops than the Slim—but if your kitchen has limited clearance above its surface, then a taller machine may be preferable because it will leave more room for mugs underneath its spout.

Water Reservoir

Both of these models have 40 oz water reservoirs, which hold up to four cups between refills. However, what’s unique about the Slim’s reservoir is that you can remove it from its base to fill it up elsewhere—like at the sink or in your refrigerator door—rather than having to lift up the whole machine to fill it as you.

Keurig Slim vs. Keurig K-Mini Plus

The Keurig Slim and the Keurig K-Mini Plus both make for excellent additions to any kitchen. Their compact size makes them ideal for smaller spaces, such as dorm rooms or studio apartments, where people are looking to save counter space without sacrificing too much in the way of convenience. Both are single-serve machines, which take up less space than a traditional coffee maker while still being able to brew up your favorite cup of joe with the same ease and consistency.

They’re also quick to heat up and easy to use—and once you’ve got a full tank of water, you can make eight cups before having to refill its reservoirs. So what’s the difference?


The Keurig Slim is an ultra-slim machine, measuring 13 inches in width, 9.9 inches in depth and 12.5 inches in height. It weighs just 6 pounds, making it easy to move around and store when you’re not using it. The K-Mini Plus is slightly larger than the Slim, measuring 14 inches in width, 7 inches in depth and 11.


The main difference between the two models is that the K-Mini Plus is about $20 more expensive than its cousin, the Slim.

Keurig Slim vs. Keurig K-Mini

If you’re looking for a Keurig that takes up a minimal amount of counter space, you might be considering the Keurig Slim—but another option to consider is the Keurig K-Mini. Both of these models are great options for small spaces, but they do have their differences.

The Keurig Slim is designed to be compact and easy to use. The Keurig K-Mini is also designed for small spaces, but it has some key differences from the Keurig Slim that could help you decide which one is right for you.

  • Price: The K-mini is around $70 cheaper than the K-Slim.
  • Size: The K-Mini is shorter, longer, and wider than the K-Slim.
  • Cup size: The K-Slim can brew a cup of coffee with up to 12 oz. of water. The K-Mini can brew only up to 10 oz. per cup.
  • Water tank capacity: The water reservoir in the K-Slim holds 9 cups while the K-Mini holds only 5 cups.

Keurig Slim vs. K-Select

When you’re making the decision on which single-serve coffee maker to buy, it’s important to consider the factors that are most important for your particular needs. If you’re looking for a smaller brewer, you might be wondering about the Keurig K-Slim or the K-Select. While both have features that make them appealing options, there are some significant differences between them.

The Keurig Slim is designed to fit into smaller spaces than traditional brewers, including those in a dorm room, office or apartment. It has a removable drip tray and can accommodate a standard travel mug, but it’s not as powerful as full-size models and doesn’t have the same array of high-tech controls and settings.

The biggest difference between these two models is the size: with a height of 12.7 inches versus 13.5 inches for the K-Select (or 15 inches with the water reservoir attached), it’s less than an inch shorter than its larger counterpart—but that inch can make all the difference if you’re trying to fit under tight cabinets or get around limited counter space. The Slim also requires more frequent refills of its 40-ounce reservoir compared with the 52-ounce capacity of the K-Select. 

Keurig Slim Frequently Asked Questions

Q: What’s the difference between this model and the 2.0?
A: The Keurig® K250 Coffee Maker is a newer, smaller version of the Keurig® 2.0 brewing system, which was released in 2014. The K250 is the same size as most classic Keurig® coffee machines, but it features a sleek and modern design that comes in more colors to suit more tastes. Like with the 2.0, this model allows you to brew a cup or travel mug size of your favorite hot beverages—including coffee, tea, hot cocoa, and iced beverages—in just minutes at the touch of a button. A bonus feature of this model is its strength control setting, which gives you the power to brew your beverages exactly how you like them.

Q: Does it have an auto-off function?
A: Yes! This model has an energy saver mode that automatically turns off after two hours of non-use.

Q: Is This Coffee Maker Noisy When In Operation?
A: The Keurig K Slim single serve coffee maker isn’t loud when brewing and has about the same noise level as a typical drip machine does. However, compared to the higher-end Keurig models, it does have a high noise level.

Q: How Long Will The Keurig K Slim Last?
A: The life expectancy for the K Slim single serve isn’t a hard and fast number. The length of time it can remain in use for your brewing needs will depend on your water quality, maintenance regime, and frequency of use. To get the most out of your coffee maker, it is best to use filtered water and perform routine maintenance and descaling.

Q: Do I Have To Use K Cups With The K Slim Brewer?
A: With many of the lower-level Keurig models, you can purchase a reusable keurig pod (like the my k cup universal pod) to use in your device. This pod can be filled with your preferred coffee grounds and utilized as you would any K Cup. However, it is essential that you take the time to rinse and wash out the reusable pod to keep it working efficiently.

Q: How Do I Clean The K Slim?
A: While you need to be sure to continually wipe down the external parts of the machine and clear out any remaining grounds that fall into the device, you also need to take time to descale your Keurig K Slim single serve. Often you can do this with a combination of vinegar and water. However, you can also opt to use Keurig’s specialty descaling solution. Before starting the process, refer to your coffee maker’s instructions for exact details.

Q: Does Keurig K-Slim need a filter?
A: If you intend to ground your own coffee or do not wish to use pods, then you will need to buy a K-Cup Universal Coffee Filter separately. Otherwise, if you intend to use pods to make coffee, the filter is not needed.

Q: Does the Keurig K-Slim make iced coffee?
A: The K-Slim does not directly dispense cold or iced coffee. However, you can still use the K-Slim to make iced coffee using special instructions. Essentially, you can simply dispense coffee over a cup of ice using your K-Slim coffee maker.

The Final Verdict

So, is the Keurig K-Slim an ideal brewing machine for you? It really depends on what you’re looking for and how you plan to use it. If you have a small family and love the convenience of single-serve coffee, this brewer can be a great choice. It’s very affordable, has a sleek design, and can make several cup sizes. But if you drink multiple cups in a day or have a large family that all want their own coffee at the same time, this might not be the best choice for you.

We recommend that large families look into the Keurig K-Select or K-Elite (at least) or consider looking at other brands as well. All things considered, we think that Keurig Slim is a great brewer and one of the best value buys out there. If you’re in need of an affordable coffee maker that will fit on your countertop without taking up too much space and won’t disappoint with its performance, then it’s definitely worth checking out!
