Our Reviews: Keurig K525 vs K425

Let’s take a look at what each of these coffee makers has to offer:

Keurig K425 Review

Overall, the K425 is a great single-serve coffee brewer. It allows you to brew in a variety of sizes, ranging from 4 ounces all the way to 30. That’s up to four cups of coffee at once!

It comes fitted with a 70-ounce water tank, which means you’ll be able to go through 9 or 10 cups before you have to refill. So the K425 is definitely suited for a family of four or more.

In addition, the K425 also sports an LCD touch display which you can use to adjust both the strength and temperature of the brew. So you can experiment with coffee flavours whenever you wish.

Coffee makers can often eat up a lot of electricity.  The K425 doesn’t have this problem thanks to the Auto off feature. This switches off the machine automatically if you let it stay idle for 90 seconds.

Probably the most noteworthy drawback of the K425 is that it doesn’t come with a water filter out of the box.

The Pros

  • Able to brew in 10 different K sizes
  • Programmable Auto-Off feature
  • Allows you to control both brewing temperature and strength
  • Coloured LCD touchscreen
  • Brews coffee in less than 60 seconds

The Cons

  • Doesn’t come with a water filter kit
  • No ‘Hot Water on Demand’

Keurig K525 Review

The K525 is the slightly improved version of the K425. Its water reservoir has a capacity of 80 ounces. This means you can get one or two cups more with each refill. Plus it’s got a touchscreen which is about 0.4 inches larger. This makes it slightly easier to read the prompts and controls.  

Additionally, it comes with a ‘Hot Water on Demand’ feature, a water filter kit and a nightlight, all of which the Keurig K425 lacks.

The Pros

  • Does everything the K425 does
  • ‘Hot Water on Demand’
  • Comes with a water filter kit and a reusable K-cup
  • Comes with a nightlight.

The Cons

  • The highest temperature setting is not appropriate for coffee brewing
  • Also a discontinued model and is relatively hard to find.

Keurig K425 vs K525: A Detailed Comparison

In this section, we’re going to be taking a closer look at both the Keurig K425 and K525. We’ll be comparing features, design, ease of use and durability.


There are a lot of excellent features that both these machines share. These include:

  • Compatibility with K-cup and K-mug and K-carafe sizes. If you have a big family, then being able to use a carafe pod is convenient. It allows you to brew up to four cups of coffee at once!
  • Strength controls – allows you to brew coffee mild, strong or even extra strong
  • Temperature control options- allow you to adjust your coffee’s flavour by experimenting with brewing temperature
  • Coloured LCD Touchscreens – they’re user-friendly and are backlit so that you can even use them in poor lighting conditions. You can also change the background light to a shade that’s more soothing to your eyes. 

However, there are a few minor differences as well:

  • The K525’s water tank is ten ounces larger, which doesn’t give it that much of an advantage over the K425. Ten ounces equals about two more cups
  • The K525’s touchscreen is almost half an inch larger. This could make it easier to read the instructions that are sometimes displayed on it
  • Only the K525’s touchscreen has a customizable wallpaper option. However, we doubt a lot of people would care much about this feature
  • The K525 comes with a water filter kit right out of the box. This isn’t the case with the K425. That being said, you could always buy one separately
  • Only the K525 comes with the ‘Hot Water on Demand’ feature which dispenses hot water in your preferred quantity. No more having to boil water on an electric kettle for a cup of tea!
  • Lastly, the K525 comes with a night light, which can be useful if you ever need to operate the machine in dim or no light.


The Keurig K425 and K525 look pretty similar. They have the same sleek look you get with the newer Keurigs. Plus their dimensions and weights are almost identical. The K425 is just a bit taller but both are compact enough to fit comfortably on most kitchen countertops.

They both come in the same colour options: black, red and platinum.

Ease of Use

The touchscreen on either coffee maker makes brewing very easy. All you need to do is select your preferred temperature, strength and size and you’re good to go! Less than sixty minutes later, you’ll be enjoying a fresh cup of coffee.

Both the K425 and K525 have removable water tanks and drip trays, which makes cleaning easy as well. Also, when you use K-cup pods you’ll create little to no mess in the first place.


Both the Keurig K425 and K525 are mostly made of plastic so don’t expect them to be the strongest coffee brewers out there. However, customers have reported long lifespans. As long as you take proper care of them, there shouldn’t be any problem.

Both machines come with a one-year warranty which we really think should be longer.

How Much Do They Cost?

The Keurig K525 is a discontinued model and could be a bit hard to find. Typically, a K525 in good condition should cost you about $150. On the other hand, the price of a brand new K425 is $240.

Things To Consider When Buying A Keurig Coffee Maker

In addition to the K425 and K525, Keurig offers a wider selection of coffee brewers. It’s usually pretty hard to choose between them so we thought we’d try and make it easier.

So here’s a list of factors you should consider when you’re trying to find the perfect coffee maker for your home:

  • Compatibility with K-carafe and K-mug: useful if you have a large family and need to brew several cups of coffee at once
  • Compatibility with other pods: most of the new Keurig brewers allow you to use pods from other brands as well. So you can use cheaper pods and potentially save a lot of money
  • My K-cup: My K-cup is a reusable coffee pod that you can use with any of Keurig’s brewers. However, it only comes pre-packaged with a few coffee makers. This includes the K525
  • Touch screen vs push-buttons: this all comes down to personal preference. Either way, all Keurig machines are simple to operate
  • Brew Size: some Keurig coffee makers offer more brew sizes than others. So consider how much versatility you need before you buy
  • Temperature control options: only the more expensive Keurig models will have temperature settings. The cheaper ones will have a fixed brewing temperature at around 89 Degrees Celsius. So if you like experimenting, we suggest looking at the premium line of Keurig coffee brewers
  • Water tank size: if you make large quantities of coffee every day then you’d probably need a model with carries a 70 or 80-ounce tank
  • Programmability: You can program some Keurig models to start and stop brewing at specific times. This is great if you want to have a cup of coffee as soon as you get out of bed.

Our Verdict: Keurig K425 vs K525

Both the K425 and K525 offer a ton of great features and most people would be happy with either. That being said, the K525 has a slight edge over its rival thanks to the larger touchscreen, hot water on demand, the somewhat larger reservoir and the nightlight.

That’s why the K525 is our pick for overall better coffee maker.

Final Thoughts: Which Brewer Should You Get?

Performance-wise, there really isn’t a significant difference between the K425 and K525. Both of them can brew coffee in less than a minute and they offer the same temperature and strength controls. Hence, if that’s all you care about, you’d be just as happy with K425.

You Should Buy The Keurig K425 If:

  • You don’t want to spend more than $150
  • You don’t mind the slightly smaller water reservoir
  • You already own a reusable K-cup pod

You Should Buy The Keurig K525 If:

  • You want all the additional features
  • You don’t mind spending $240
