The Bottom Line

The K45 is one of Keurig's most iconic brewers. It's simple and easy to operate with a solid 48 oz reservoir, but it has just a 10 oz max brew size and no special features. Now discontinued, check out the K-Classic instead.

Keurig K45 Overview

The K45 is one of Keurig's flagship brewers and was introduced as an upgrade to the B45, though the two models have the exact same specs.

Currently discontinued, the K45 has been replaced by the K-Classic, which offers many of the same features:

48 oz reservoir
No Strength Control or Temp Control
Auto-On/Off functionality and removable drip tray
No pod-scanning system (found on Keurig 2.0 brewers) so it's compatible with all types of K-Cups

The only differences between the K45 and K-Classic are the K-Classic's slightly expanded brew sizes (6, 8, and 10 oz) plus its upgraded brewing system that ensures you're brewing with Keurig's latest and greatest technology for hotter, stronger cups.

You may also see 4 model numbers that look identical: K40, K45, K50, and K55.

What's the difference?

The K40 and K45 were originally released as Keurig's K-Elite brewers. Both came with the K-Cup variety pack, but the K45 also came with the water filter starter kit.

In 2015, Keurig rebranded the K40 and K45 K-Elite brewers as the K50 and K55 K-Classic brewers.

Pros

No pod-scanning technology so brews both licensed and unlicensed K-Cup pods
The iconic brewer that put Keurig on the map
Foolproof to use
Comes with K-Cup variety pack and water filter starter kit

Cons

Discontinued model
Only 2 brew sizes (8 oz, 10 oz)
No Brew Strength, Temp Control, or other features
Doesn't come with the reusable My K-Cup

Is the Keurig K45 for you?

Are Keurig K45 for you?

The discontinued K45 is still worth purchasing if you can get a good deal. It doesn't have any outdated tech that limits its usability and is still a quality model if you don't mind losing the 6 oz brew size.

If you like the K45 but don't need the water filter starter kit, take a look at the K40.

However, we really do recommend going with the K-Classic, which is currently in production, supported by Keurig, and has all of the features you'd find on K40-K55 brewers.

Keurig K145 OfficePRO

Overall Rating: 84

Keurig's most basic office model, the UL Commercial listed K145 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.

Once Keurig's most feature-rich brewer, the K79 Platinum Plus brews 4-12 oz coffees with a huge 72 oz reservoir and Temp Control. Now discontinued, take a look at the K-Elite. It offers everything on the K79 and a bunch more.

About The Coffee Maven

Bryan De Luca

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!
