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 K-Duo Plus

Keurig K-Duo Plus
Overall Rating: 88
The K-Duo Plus is Keurig's most versatile coffee maker, brewing both single-serve K-Cups (up to 12 oz) and full 60 oz carafes with a convenient swivel water reservoir designed to fit your counter's configuration.

Keurig K250

Keurig K250
Overall Rating: 84
The base model of the now-discontinued Keurig 2.0 pod-scanning system, K200 series brewers are an affordable option for those who want to brew multi-cup carafes, but we recommend the in-production K-Duo.

Keurig K15

Keurig K15
Overall Rating: 80
One of Keurig's original "Mini" K-Cup models, the K15 has a max 10 oz brew size with its "fill before each use" reservoir. Now discontinued, the K15 has been replaced by the slimmer K-Mini, which brews up to 12 oz K-Cups.

I'm Bryan but most people know me as The Coffee Maven. I grew up outside Boston, Massachusetts and received my Bachelor's degree in Biochemistry from Providence College. My first introduction to coffee was during my college days, when I used it as a source of caffeine to fuel late-night study sessions, but soon I became obsessed with the chemistry of coffee. How did changes to water temperature or contact time affect its taste? Why do beans from Africa taste fruity while beans from Indonesia taste spicy? I launched The Coffee Maven in February 2017 to explore these questions and help others brew their perfect cup. Welcome to my site, and thanks for reading!
