Keurig k Slim Vs k Mini vs mini plus | Main Differences

Water tank

Removable water reservoirs are more user-friendly as they are easy to clean and refill. It is not very easy to clean attached water reservoirs.

Keurig K Slim has a 46 ounces removable water reservoir, so you can easily brew 4 to 5 cups of coffee without refilling the machine. 

You can easily detach this water tank from the coffee machine for easy cleaning and refilling with its convenient holder at the back.

Keurig K Mini doesn’t have a removable water reservoir, and it can hold only one cup of water. So, you have to fill the machine every time you want to brew coffee.

Keurig Mini Plus has a single cup removable water reservoir.

Both Keurig Mini and Mini plus have a similar water reservoir that has a convenient scale from 6 oz to 12 oz. So, you don’t have to measure the water before filling it into the reservoir.

The only difference is a water tank of Keurig mini plus is removable while in Keurig mini it is not removable.

Color choices

If you’re a choosy person and you are going to buy a coffee maker, you might want to look at the color choices available for your machine.

Keurig K-slim comes in three colors black scarlet red and white. While there are seven color options available in Keurig K-mini and K mini plus, and you can easily find your favorite color in these machines.


Brew Size

The brew size directly affects the intensity of the coffee if you are using pods for brewing. If you select a large cup size, then your cup of coffee will be less intense, and if you choose a small one, it will be intense as the amount of coffee grounds in the pod remains the same in both cases.

Keurig K-slim has an option of 8, 10, and 12 oz. You can easily brew a cup size of your choice by pressing only one button.

Just press the 8, 10, or 12 oz button, and then press the “K” button and your coffee will be brewed.

Keurig K-mini and K-mini-Plus have a single round “K” button at the top for brewing coffee.

The size of the brew depends on the amount of water you fill in the water tank.

So, just fill the water anywhere between 6 to 12 oz and push the “K” button and your coffee will be ready.

Keurig Mini Brew options

Strong brew function

If you are a fan of strong brew, then both K-Slim and K-Mini will not be perfect. But K-Mini Plus has an option for strong coffee.

In addition big “K” button Keurig Mini Plus also has a “strong” button.

This button slows down the brewing process so the water extracts more flavors from the coffee grounds and you will get a strong and intense cup of coffee.

Unfortunately, all these machines do not have any settings for iced coffee. If you are a fan of iced coffee and often brew one, these machines will surely disappoint you.

Cord and Pods Storage

All these machines are compact and slim and weighs only around 5 to 7 pounds. So they are all well suited for travelling purposes as you can easily take them wherever you want.

For traveling purposes, it is very convenient to have the storage option for cord and coffee pods.

Keurig K-slim do not have both the cord and coffee pods storage. Morevover, it has a very large water reservoir which makes it non suitable for travelling purposes.

Keurig K-mini and Mini Plus have almost a similar design and have cord storage at the back.

The length of the cord is 24 inches for both machines and can easily be packed at the back of the machine.

In the package of Keurig mini Plus, you will also find pod storage box, in which you can easily store up to coffee pods.

Keurig k-Slim Vs k-Mini | Key Similarities

Compact design

All these machines have a very decent and compact design. All these machines are 4 inches wide, so they can easily fit on the counter of your kitchen or office.

Moreover, seven different color options are available in Keurig Mini and Mini Plus, while Keurig Slim comes has only three colors to choose from.

Auto-off feature

If you are a forgetful person, this feature will excite you the most. It is estimated that more than 80% of electrical appliances broke off just because we forgot to turn them off.

Keurig K-slim turns off automatically after 5 minutes of the last brew, while Keurig k-Mini and Mini Plus turn off automatically after 3 minutes of the last brew.

This feature saves your machine from deadly electrical shocks and saves you a lot of amounts in the bill of electricity.


All these machines are compatible with k-cup pods. There are more than 400 varieties of k-cup pods; you can easily find the one that suits your taste the best.

No problem, if you are not a fan of k-cup pods, you can buy a reusable k-cup filter and fill it with the coffee grounds of your choice to make a perfect brew for yourself.

None of these machines can work with whole coffee beans.

Space for cup and Drip trays

All these machines have a removable drip tray beneath the dispenser on which we place the cup.

This tray takes care of drops that might fall out of the dispenser after taking off the cup. You can easily remove this tray for cleaning purposes.

And if you want to brew coffee in a travel mug up to 7 inches tall, you have to remove this tray first.

Keurig K-Slim has a space of 6.2 inches for the cups and Keurig K-mini and K-mini plus has a space of 6 inches for the cups.

The drip trays in all these machines are removable. After removing the tray we can get an extra inch. So these machines can easily accommodate travel mugs up to 7 inches tall.

Which one you should Buy? | Keurig Mini vs slim VS mini plus

All these Keurig Models brew a perfect cup of coffee and they are among the best single serve coffee makers

If you have limited space, you must go with K-mini or Mini plus as they occupy less space than K-slim. All these machines are 4 inches wide, but K-slim has a water reservoir attached to the back of the coffee machine. That’s why it occupies more space.

Although Keurig K-slim is more expensive than both the mini and mini plus but it has some additional features which are very useful. Like it has a water reservoir so you don’t have to fill water every time you brew and it has descale alert which is very useful for cleaning purposes.

But there is a major drawback of Keurig Slim that you can’t brew a strong cup of coffee in it. And the minimum size is also 8 oz which is pretty large for brewing k-cup cods. So, if you are a strong coffee you certainly don’t want to go with Keurig slim.

OUR RECOMMENDATIONS | Keurig k-mini Plus

My recommendation is you must go with K-mini Plus as it offers many additional features. K-mini Plus has strong brew options not present in both K-mini and K-slim. K-mini plus has a removable one-cup water reservoir. It has storage for both cord and pods.

So, this machine is also very travel friendly; you can easily take it anywhere you want. It is available in multiple color options and has an exquisite design.

And there is not much price difference. So my recommendation is you must go with Keurig K-Mini Plus.
