Keurig's K-Slim single serve coffee maker is a K-Cup brewer less than 5 inches wide, with a removable 46 oz reservoir that holds enough water for up to four 8 oz cups before a refill. It brews 8, 10 or 12 oz cups at the push of a button, shuts itself off 5 minutes after the last brew, and uses MultiStream Technology, which Keurig says extracts more flavor and aroma than its K-Classic brewer. Keurig lists it at $149.99, with $89.99 shown as the sale price on keurig.com.
What is the Keurig K-Slim single serve coffee maker?
It is a pod brewer from Keurig's current line, built to take up very little counter space. Keurig describes it as less than 5 inches wide, and its dimensions out of the box are 12.14 inches high, 4.76 inches wide and 15.2 inches deep, or 17.28 inches high with the handle open. It comes in four colors on keurig.com: black, white, scarlet red and storm blue.
You lift the handle, drop in a K-Cup pod, close it, pick a cup size and press brew. The water comes from the reservoir at the back, which is removable, so you can carry it to the sink. It keeps a multiple-cup reservoir, so you are not filling it for every mug.

How the Keurig K-Slim MultiStream brewing and reservoir work
MultiStream Technology is the one change Keurig puts first in its feature list. The company says it extracts more flavor and aroma in every brew, measured against its K-Classic brewer with an Original Donut Shop K-Cup pod. That comparison is Keurig's own and nobody has tested it for this page, so treat it as the maker's claim and not a measured result.
The reservoir is the practical difference from a one-cup design. At 46 oz it lets you brew up to four cups of 8 oz before refilling, and because it lifts out, you can fill it at the tap. The drip tray also comes out, so a travel mug up to 7.0 inches tall fits underneath, and Keurig says the tray holds a full accidental brew, which makes cleanup easier. The auto off feature turns the machine off 5 minutes after the last brew.
If you prefer your own ground coffee, the My K-Cup universal coffee filter is listed as compatible. It is sold separately, so it adds to the cost.
Keurig K-Slim vs Keurig K-Mini
The Keurig K-Mini is the closer rival on width, since it is also under 5 inches wide. It lists at $71.00, uses a 0.35 l single cup reservoir that is filled for each brew, takes cups from 8 to 12 oz and shuts off 90 seconds after the last brew. The K-Slim costs more but swaps the fill-per-cup reservoir for a 46 oz tank, brews 3 set sizes, and waits 5 minutes before turning off.
The K-Mini's published travel mug clearance is 178 mm, about 7.0 inches, which matches the K-Slim's 7.0 inch figure. So the choice comes down to filling the tank once for several cups against filling a small reservoir for each mug.
Keurig K-Slim vs Keurig K-Express
The Keurig K-Express lists at $69.99, draws 1001 W and also brews 8, 10 and 12 oz cups with a 5 minute auto off. Both use K-Cup pods. Keurig's K-Slim page states a width of less than 5 inches and a removable multiple-cup reservoir with MultiStream, which are the two things to weigh against the K-Express's lower list price. The K-Express page publishes a wattage, which the K-Slim page does not.
Is the Keurig K-Slim worth it?
At the $149.99 list price it sits at the top of Keurig's basic single serve range, and the sale price of $89.99 shown on keurig.com is a different proposition, so check what it costs on the day you buy. For that money you get a narrow footprint, a reservoir that is not refilled per cup and MultiStream. What you do not get is a milk frother, a hot water function or temperature control, since none appears in Keurig's feature list. Nobody has tested it for this page, so there is no claim here about taste, speed or noise.
K-Cup pods are the running cost, and Keurig's page publishes no price per pod. If you are comparing pod brewers on price and features, the pod and capsule machines category has the full list.
The numbers that matter when you compare it are the reservoir, the width and the cup sizes: 46 oz, less than 5 inches and 3 sizes from 8 to 12 oz. Weight is 6.22 lb, so it is light enough to move from a counter to a cupboard, and the cord is 29 inches long, which limits how far the outlet can be from the machine.
Who should buy the Keurig K-Slim (and who should not)
It suits a small kitchen, an office desk or a dorm where width matters but you do not want to fill a tiny tank for every cup. The 7.0 inch clearance takes most travel mugs, and the 3 sizes cover a regular mug.
It is not for someone who wants lattes, a frother, a 6 oz small cup or app control, none of which Keurig lists for this model. If you want those, look at a Keurig with a milk system. Anyone who wants a price guarantee should also remember that Keurig's page shows two prices.
