Key Features and Differences Between the Keurig K Slim and Keurig K Mini

Water Tank Capacity

Depending on your preferences for water capacity, you may find that the Keurig K Slim is a better option than the Keurig K Mini. The Keurig K Slim can hold 48 oz of water and make up to 8 small cups of coffee, while the Keurig K Mini can only make two 6 oz cups at most. That means you have to fill the tank each time you want to use it. This reduced tank capacity isn’t an issue if you have easy access to fresh water, but others may find the Keurig K Slim is the best fit.

Removable Water Reservoir

The fresh water reservoir capacity isn’t the only important difference when comparing a Keurig slim vs mini. Keurig K Slims are also built with a removable water reservoir, which makes it easier to refill and clean the reservoir. The Keurig K Mini does not have a removable water tank. To refill it, you’ll need to add water from a mug or measuring cup directly into the top of the coffee maker. If you need to clean the Keurig K Mini, you’ll need to work around the entire device.

Multistream Technology

Numerous features can improve the taste of your cup of coffee. Multistream brewing technology is one of the best features to look for when you’re shopping for your new Keurig coffee maker. This signature feature extracts a much stronger and better flavor from K-Cup pods than conventional Keurigs, resulting in a much better cup of coffee. It does this by adding more holes to the top of the K-cup so that more water can flow through the pod. If you want a Keurig with multistream brewing, you should consider choosing the Keurig K Slim.

Indicator Lights

If you’re unfamiliar with Keurigs, the machines can quickly become too confusing. Many people find the Keurig K Slim easier to use than the Keurig K Mini because it offers a few indicator lights. These lights will let you know if you forget any crucial steps or if your coffee maker needs any maintenance.

Compatibility with Ground Coffee

While K Cup pods are convenient, they aren’t always the best option. There aren’t nearly as many types of K Cup pods available as regular grounds, and they’re often much more expensive. Luckily, many Keurigs offer compatibility with grounds if you use a special reusable Keurig coffee pod cup. Both the Keurig K Slim and Keurig K Mini offer compatibility with this reusable coffee pod, so you can choose whatever ground coffee you want.

Dimensions

Depending on your space restrictions, you may find that the Keurig K Mini is a better option than the Keurig K Slim. Both machines measure at a similar height and width, but the Keurig K Slim is around 4 inches longer than the Keurig K Mini due to the large water reservoir in the back. If you prefer to purchase a Keurig that won’t take up as much counter space, the Keurig K Mini is the better option.

Removable Drip Tray

If you want the perfect Keurig machine, it’s essential to ensure it comes with a removable drip tray. This makes the machine much easier to clean and allows you to use the Keurig with cups that are an inch or two taller than the clearance between the dispenser and the drip tray ordinarily. Luckily, the Keurig K Mini and Keurig K Slim include an easily removable drip tray.

Auto Off

It can be extremely easy to forget to turn your Keurig coffee machine off when you rush out the door. Unfortunately, this can result in wasted power — and it’s never a good idea to leave an appliance running unattended in the first place. Luckily, both the Keurig K Mini and the Keurig K Slim offer the Auto Off feature, ensuring that the device will shut itself down even if you forget to do so.

Altitude Mode

It might seem surprising, but the altitude you live in can actually impact the brew quality of your next cup of Keurig. Unfortunately, using your Keurig at extremely high altitudes without the right settings can result in poor-quality taste. If you want the best experience with your Keurig at high altitudes, you should purchase a machine like the Keurig K Slim that includes altitude mode.

Descaling Alert

Keeping your Keurig machine in the best condition means keeping up with regular maintenance routines like descaling. Both machines can run a descaling cycle, so you can easily clean the device regardless of which type you choose. It’s important to note that the Keurig K Slim also includes an indicator light to tell you when to descale, which can help forgetful Keurig owners keep their devices in the best condition.

Color Options

If you’re a fan of purchasing all your home appliances in your favorite color, you’ll be delighted with the options available for the Keurig K Mini. Unfortunately, the Keurig K Slim is only offered in black at most retailers, though red and white varieties are on the Keurig website. If you purchase the Keurig K Mini, you can choose from various fun colors such as mint, red, gray, green, and pink.

Pricing

Both Keurigs are similarly priced when you consider the value they provide to a home. You can purchase the Keurig K Slim for $129.99 on Amazon, while the Keurig K Mini is priced at a slightly more budget-friendly $99.99. Both machines are reasonably priced, considering the quality and breadth of features offered to users. From time to time, you may be able to sales prices on each model, up to $30.

Is the Keurig K Slim or Keurig K Mini Better?

Neither the Keurig K Slim nor the Keurig K Mini is better. Both machines offer features that can make their users’ lives significantly easier; simply put, they brew delicious coffee cups. The Keurig K Slim is generally a better choice for anyone looking to enjoy all the extra features. If you just want a basic cup of coffee, however, the Keurig K Mini packs the essentials with various fun color options and an affordable price.

What About the Keurig K Mini Plus?

If you’ve been shopping around for a Keurig, you may have noticed another model called the Keurig K Mini Plus. What is the difference between the K Mini and K Mini Plus? The first key difference is that water reservoir on the K-Mini Plus is removable. That makes it easier to fill from your sink or refrigerator water filter.

The K-Mini Plus also has a strong brew feature. If you’ve ever been disappointed with a weak cup of coffee before, it’s easy to understand why the strong brew setting is such an important feature. Unfortunately, it isn’t included on every Keurig. If you want to use the strong brew setting, you’ll need to purchase a Keurig K Mini Plus.
