When you buy a coffeemaker from well-known brand such as Keurig, you already know that you’ll get a great cup of coffee every time. But since there are so many Keurig models on the market, choosing the right one may prove to be tricky. To help you select the perfect coffee maker for you, we compared the Keurig K40 Elite and the Keurig K45 Elite.

It’s all about the features

When it comes to features, both the Keurig K40 Elite and the Keurig K45 Elite have a lot to offer, including the ability to brew three serving sizes (6, 8 and 10 ounces). Both also boast an auto-off feature and a large, 48-ounce removable water reservoir. With so many coffee-brewing features in common, where does the difference between these makers lie? Let’s take a look.

Sizing up your space

The Keurig K40 and K45 Elite are both around the same size at a little over 13 inches tall and 10 inches wide. They also both weigh around 12 pounds. If counter space isn’t an issue, you can opt for either model.

Does it filter the water?

When it comes to the system within these coffee makers, both the K40 Elite and the K45 Elite offer a 48-ounce water reservoir and a removable drip tray. They differ, however, with regard to water. The K45 boasts an included water filter kit, allowing users to have filtered water on demand. If you live in an area with hard water, this feature might be especially appealing to you.


Aside from the aforementioned differences, since these two machines are so similar in both appearance and function, it’s likely that your final decision will come down to price. So what’s the difference between these two? About $20 and six K-Cups.

At Amazon, the Keurig K40 Elite Brewing System retails for $119.99, although we’ve seen it on sale for less than that. The maker comes complete with a 6-pack or K-Cups. Buy the Keurig K45 Elite Brewing System in black from Amazon and you’ll be paying $97.88. This model includes a 12-count variety pack of K-Cups.

A final thing to consider is that both these coffee makers are older models. The K45, for instance, has been replaced by the K55. If you’re interested in expanding your search beyond just these two, take a look at NerdWallet’s roundup of the best Keurig coffee makers.
