Keurig K425 vs K475: What's The Difference?

Keurig K425 vs K475: Wow do you tell these nearly identical brewers apart?

Don’t worry, you aren’t the first person to ask this question.

Keurig has been confusing would-be buyers for years as they’ll give two almost identical brewers different model numbers that make one seem better than the other.

In most cases it’s simply a matter of Keurig modifying some unnamed internal component or changing the accessories the brewer comes with in order to get you to spring for the newer model.

Is that the case here?

We explain below in The Coffee Maven’s Keurig K425 vs K475 Showdown.

Keurig K425 vs K475: The Differences

Not a lot of differences in that table, huh? Let’s sum them up:

The Keurig K475 comes with a water filter starter kit. The K425 doesn't.

Yeah, it’s a short list.

That Keurig 2.0 water filter starter kit is valued at $12-$15, so click the Check Current Price buttons in the table above to see if you’re getting a good deal on the K475 with that $12-$15 accessory included.

Note: If you pour filtered water into your Keurig’s water reservoir, you don’t need a charcoal filter!

Both the K425 and K475 are K-Carafe compatible, but the carafe is sold separately. If you want to buy a K400 series brewer that comes with the carafe, go with the K450.

Keurig 2.0 Explained: Comparing the K200, K300, K400, and K500 Series

Keurig’s 2.0 brewing system primarily can be found in around a dozen models that span these four series:

  • K200
  • K300
  • K400
  • K500

The differences between the K425, K475 and even the K450 are detailed above, but spec-wise they’re all representative of the K400 series.

Reviewing the Keurig K425 vs K475

As mentioned above, both of these models are from the Keurig 2.0 product line, and more specifically from the Keurig K400 line.

So let’s review these K400 brewers.

First, the Keurig 2.0 system in all of the above models is identical. There are small tweaks to available settings, such as the addition of Auto-On and strength control, but the technology is all the same.

In my opinion, the major jump is from the K200 series to the K300 series with the addition of the Temperature Control feature. The biggest complaint among Keurig owners is that their coffee just doesn’t get hot enough, and Temperature Control allows you to dial it up to get a few extra degrees.

For that reason I think the K300 brewers are the best value, and I view the K400 brewers as an awkward intermediate step.

Here’s my Keurig 2.0 rundown:

  • Cheapest Models: K200 brewers
  • Best Value Models: K300 brewers
  • Best Overall Models: K500 brewers

Where does that leave the K400 brewers?

Cheap exposure to a color screen I guess.


The K300 series is extremely hard to find, and that’s where the K400 brewers have their value. If you want more features than the K200 brewers, don’t want to pay top dollar for the K500 brewers, and can’t find the K300 brewers, where does that leave you?

Yup. Back with the K400 brewers.

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!
