The Bottom Line

Keurig's largest compact brewer, the 4.8" K-Slim keeps the narrow width of the K-Mini and K-Mini Plus but offers a relatively massive 46 oz water reservoir and a removable drip tray accommodating mugs up to 7" tall.

Keurig K-Slim Overview

If you're looking for a slim single-serve coffee maker with a tiny countertop footprint, Keurig has you covered with 3 different brewers measuring just 4.8" wide:

  • K-Mini: 4.5" wide and brew up to 12 oz but refill before each use
  • K-Mini Plus: Same as the K-Mini but adds Strength Control
  • K-Slim: Just 4.8" wide with an impressive 46 oz water reservoir

Note: Technically, Keurig also makes the 4.5" K-Suite Premium, but that's a commercial brewer intended for hotel rooms and vacation rentals and not for home or office use.

Unlike the K-Mini and K-Mini Plus, which brew all of the water you pour into the reservoir, the K-Slim gives you 3 preset brew sizes from 8-12 oz in the same Mini-style design and a relatively massive 46 oz water reservoir.

While Keurig has released several models with much larger water tanks (75 oz on the Keurig K-Elite), 46 oz isn't anything to scoff at. That's almost the same size as the K-Classic's 48 oz reservoir, and the K-Classic is twice as wide at 9.8" with just a 10 oz max brew size.

The K-Slim's biggest downside?

Though it packs a 46 oz reservoir into a sleek package, the brewer's design makes its water reservoir non-removable. To refill, you need to pour water into the rear-positioned tank, which can be a problem if you don't have much over-brewer clearance.

Pros

  • Includes Keurig's upgraded system for richer coffee and quieter brewing
  • No pod-scanning technology so brews both licensed and unlicensed K-Cup pods
  • Slim design like the K-Minis but has a larger 46 oz reservoir

Cons

  • Only 3 preset brew sizes
  • No Brew Strengths or Temp Control features
  • Rear-positioned water reservoir is harder to access and refill
  • Doesn't come with a water filter kit

Is the Keurig K-Slim for you?

Is Keurig K-Slim for you?

The K-Slim is the ideal brewer is you're looking for a narrow machine that doesn't need to be refilled before each use and can deal with the non-removable reservoir and lack of Strength Control.

If you're looking for a compact brewer with a removable reservoir (but no Strength Control), take a look at the K-Compact.

If you're looking for Strength Control (but a non-removable reservoir), take a look at the K-Mini Plus.

If you're looking for a stylish machine with both a removable reservoir and Strength Control, the K-Select is for you.

Keurig K525

Keurig K525
Overall Rating: 88
The crown jewel of the Keurig 2.0 pod-scanning system, feature-rich K500 series brewers offer 11 brew sizes (up to 30 oz) and massive 80 oz reservoir. Now discontinued, we recommend the Keurig K-Duo Plus instead.

Keurig K-Duo Essentials

Keurig K-Duo Essentials
Overall Rating: 86
A replacement for the discontinued K200-K575 brewers, the K-Duo brews both single K-Cups and full 60 oz carafes with the reusable Gold Tone filter. This is the most basic of 3 K-Duo models and includes just the Essentials.

Keurig K140

Keurig K140
Overall Rating: 84
Keurig's most basic office model, the UL Commercial listed K140 has an underwhelming 48 oz reservoir and max 10 oz brew size, but the Drain Brewer function is handy and its sturdy build makes it great for heavy use.
