Because it holds more than a liter of water, the Keurig K-Slim’s water reservoir can serve more cups for a longer time up to the last brew.

This saves a lot of time having to refill the water reservoir, as, despite the Keurig K-Slim’s slim design, it can still accommodate a reasonable amount of cup servings.

This is an easily overlooked feature in many coffee makers because a removable drip tray ensures that no water stagnates in the coffee machine.

Brew Size Options

Because of this versatility, the Keurig K-Slim allows three different-sized serving options namely 8 oz, 10 oz, and 12 oz.

While a little less than other coffee machines, the Keurig K-Slim’s ability to provide these different sizes is a great factor considering its slim, space-saving design.

Who is the Keurig K-Slim for?

Tiny, quick, and quiet – the Keurig K-Slim is a coffee machine for people who like compact, aesthetically pleasing, and convenient kitchenware.

It fits right into any corner and takes up very little counter space.

The K-Slim also maximizes servings with its 46 oz water reservoir – which can serve up to 4 to 5 cups of coffee.

Compared to traditional coffee makers, the Keurig’s K-Cup pod coffee is much easier to prepare on the fly.

If you’re the type who’s always in a hurry and just need that single-serve coffee ASAP, the Keurig K-Slim will suit your lifestyle.

Also, if you hate complicated clean-ups, fret not because the Keurig K-Slim’s drip tray and water reservoir are easy to access and refill.

Potential Drawbacks

The Keurig K-Slim is a pretty straightforward coffee machine so it does have its limitations.

For one thing, you can’t froth milk with the Keurig K-Slim.

If you’re a big latte fan, the Keurig K-Slim coffee might not be up your alley.

While the Keurig K-Slim has three brew sizes to choose from, these may not be sufficient for some customers who prefer large serving cups.

Also, while the Keurig K-Slim may have a fairly large water reservoir, this can not be removed and might come as a hindrance when the time comes to refill it.

If the Keurig K-Slim is set up in a corner, refilling the water tank may be a challenge.

Speaking of positioning, the Keurig K-Slim and its small size are matched with an even smaller power cord.

Good luck trying to find the right spot for the Keurig K-Slim, or better yet purchase an extension cord ahead of time.

The K-Slim coffee maker is a simple machine so customizing drinks and brew strengths are not really its specialty.

The K-Slim coffee maker also lacks temp control, which is standard in other coffee makers.

Perhaps the most major downside of the K-Slim coffee maker is that it doesn’t come with a water filter kit.

Replacing the water filter of your Keurig K-Slim coffee maker will be an added purchase – given that you can find that filter that actually fits in the K-Slim coffee maker.

Owing to its design, the K-Slim is definitely something that sits aesthetically well in any kitchen.

With the innovative K-Cup pod, coffee becomes less of a chore and more enjoyable thanks to this futuristic single-serve coffee maker.

Because of its reasonably-sized water tank, the Keurig K-Slim makes for a decent coffee brewer that can serve K-Cup pod after pod when it has to.

Does K-Slim need a filter?

Yes, and it even accepts the universal K-cup filter which you can brew stronger drinks in.

The filter for the K-Slim helps remove any unwanted coffee grounds that may seep in from the K-Cup pods.

The Keurig K-Slim package doesn’t come with a water filter kit, but you can purchase it in designated retailers.

How does the Keurig K Slim work?

The Keurig K-Slim makes coffee using K-Cup pods that come in various flavors.

The pods are inserted in a designated compartment on top of the K-Slim, you prepare the correctly-sized cup underneath, and then you select the brew size of your choice.

The Keurig K-Slim will then process this flavor pod into coffee – using the water stored in the water reservoir.

Does the Keurig K-Slim take regular K-Cups?

Yes, in fact, this is the standard cup size for all the single-serve coffee brew sizes.

While you can utilize other cups and mugs for the K-Slim, K-Cup are made to fit into the Keurig K-Slim machine.

What is the difference between the Keurig Mini and the Keurig K-Slim?

Both the Keurig Mini and the Keurig K-Slim make coffee using K-Cup pods.

However, one big difference is that the Keurig Mini has a small water tank which you have to refill after every cup of coffee you make.

Compared to the K-Slim which has a large water reservoir that keeps a decent amount of water good enough for 4 to 5 cups of K-Cup pod coffee.
