Keurig K-Slim 

The Keurig K-Slim is a single cup coffee brewer that uses K-Cup pods. It’s the smallest of the latest generation of Keurig brewers and comes with a compact design that can sit on your kitchen countertop without taking up much room. It has a large color touchscreen display that is easy to read and use. You can use this machine to brew iced beverages, hot drinks, specialty drinks and more. The machine features five temperature settings and two brew sizes so you can customize your drink experience.

Keurig K-Express 

Keurig K-Express is a single cup coffee brewer, which means it brews only one cup of coffee at a time. It does not have a water reservoir, so you need to refill it after every use. The machine itself is very compact and can easily fit into small spaces. The entire brewing process takes less than 2 minutes (including the time to heat up the water). You can get your coffee ready in less than 5 minutes in the morning! Keurig K-Slim is a single cup coffee brewer as well.

Compare Keurig K-Slim and Keurig K-Express

They both use the K-Cup pods, which means you can brew your favorite coffee with just one touch. The main difference between these two coffee makers is that the Keurig K-Slim uses smaller cups for a more compact design, while the Keurig K-Express is larger and has a larger water reservoir. And if you are interested, here are the comparisons of more Keurig coffee makers.


The dimensions of the Keurig K-Slim are 12.1” H x 4.7” W x 15.2” D and the dimensions of the Keurig K-Express are 12.87″ H x 4.56″ W x 12.87″.  They can be slightly different depending on the model you choose, so always check out the details before purchasing one!

Color choices

The Keurig K-Express comes in only black. The Keurig K-Slim has 4 color versions, black, read, white and gray.

Cup Sizes

The K-Slim and K-Express are the same machine, but they have different cup sizes. The K-Slim is available in a single cup size that holds 250ml of coffee and features a removable water tank. The K-Express is available in three different sizes: 60 OZ, 100 OZ, and 187 OZ (regular).

The Keurig K-Slim has a removable water tank that can be filled with up to 10 cups of water before emptying into the garbage. The water tank also holds about 300 ml of coffee grounds for use when brewing with the included reusable filter basket.

The Keurig K-Express has an integrated water reservoir with an extra large fill line that helps you see how much water is left in the reservoir so you can plan ahead for when you need more!

Pods or Grounds

Both Keurig K-Slim and Keurig K-Express are single serve coffee makers that can brew one cup of coffee at a time. They use pods, which are the same as those used in your Keurig 2.0 brewer. The pods can be bought at most grocery stores and some pharmacies in the form of single serving sizes for about $4-$5 each or larger refill packages for $10-$12 each.

You also have the option to brew a pot of coffee with two bags, which will be more expensive than just buying a bag of coffee grounds and brewing it yourself, but not nearly as much as purchasing a full size Keurig machine with its own reservoir and water filter and then buying all new pods every few weeks.

Removable Water Reservoirs

Keurig K-Slim and Keurig K-Express come with a removable water reservoir that can be refilled easily and quickly. The reservoir is located on the front of the machine and has a large opening for easy access. It also has a built-in handle so that you don’t have to worry about spilling water while refilling it.

The main difference between these two models is in how they make coffee. The K-Slim uses a larger pod but doesn’t have an internal filter like the K-Express does. This means that you will need to use filters or paper filters when brewing with either machine.

Removable Drip Trays

One of the most important differences between these two coffee machines is that the drip tray. The drip tray of K-Slim is removable while that of the K-Express isn’t.

This means that you can easily clean it if there is any spillage into your machine or if someone accidentally drops something on it while brewing their coffee or tea. You can also take out this drip tray if you want to change its position or if you want to keep it somewhere else where it won’t get damaged due to frequent washing.

This can be very useful if you live in an environment where dust settles down on everything, especially when you’re not using your machine regularly.

Strong Brew Option

Keurig K-Slim is a newer model than Keurig K-Express and it has more features than the latter. The manufacturer claims that the new brewing system in it delivers stronger brews than what you can get from other Keurig models. It also comes with an auto on/off feature which allows you to set up your brewer to start brewing when you wake up in the morning, so you can have your favorite coffee ready by the time you get out of bed.

Pod and Cord Storage

When it comes to the K-Slim and K-Express, the pod and cord storage are both very similar. Each model has a drawer that can hold up to three pods, and each one also has a cord storage area. The only difference is that the K-Slim has a drawer that can hold up to four pods, while the K-Express can hold up to five pods in its drawer.

The drawer of both models lets you store any size of pod, which is nice if you have a variety of different-sized pods at home. The size of these drawers is also very similar; each one is approximately 8 inches wide by 12 inches deep by 10 inches tall.

Travel Mug Friendly

Both models have a travel mug friendly lid, but there are other differences between these two brewers that can help you decide which one is best for you. The main difference between these two models is that one has an integrated hot water system and one does not.

The Keurig K-Slim only brews coffee or tea pods, while the Keurig K-Express allows you to brew coffee or tea pods as well as hot water for use in other beverages such as oatmeal and ramen noodles.

Both brewers allow you to use 12, 18, 24 and 30 oz mugs with their respective lids; however, if you want to use larger mugs then you may need an additional accessory such as the My K-Cup Universal Reusable Coffee Filter (sold separately) or My KCup Premium Reusable Coffee Filter.

Indicator Lights

Keurig K-Slim and Keurig K-Express have indicator lights that display when the brewer is ready for use and when it is not pumping water through the machine.

However, there are some differences: Keurig K-Slim has an indicator light above each side mug holder with three colored lights (green, amber and red). This means that you can see at a glance if everything is working properly or if there is an issue with your brewer. It also helps make it easy to diagnose any problems when brewing coffee or tea. Keurig K-Express has only one color light that indicates whether everything is working correctly or not.

Which one should you buy?

The answer is the Keurig Slim single serve brewing system.

The Keurig K-Slim is the smallest Keurig machine on the market. It’s also a pod coffee maker that brews from single serve coffee pods, hot chocolate and tea. You can use your own favorite hot beverages or even add extra ingredients for your own custom blends.

The Keurig K-Slim is available in purple and red, but either color will work with any of the other K-Cup sizes. In fact, it’s compatible with all standard K-Cup sizes, whether they’re their 1.0 or 2.0 size. The only downside to this machine is that it doesn’t have a water filter, so you won’t be able to brew cold water at home and store it in the fridge for later use if you want to make iced coffee or tea on demand.


In terms of price, performance, and savings, the K-Slim vs K-Express comparison leaves us with one resounding decision: go with the K-Slim. Regardless of your coffee preferences, there is more to gain from the K-Slim than just a few dollars. If you are looking to save money, and get an excellent coffee experience, then you really cannot go wrong with the Keurig K-Slim.
