It’s not a surprise these two Keurig coffee machines are confusing due to their design and size. From the outside, they look pretty near identical, so why are they even considered different machines?!

In this comparison, you’ll see side by side the details of the Keurig K425 vs K475 to determine their differences and advantages.

Keurig usually manufactures the same models with a slight addition of features but the design remains the same. The brand has some quality and high performing coffee market and the K425 and K475 are no exception.

So what’s the difference between Keurig K425 vs K475?

The main difference is the Keurig K475 comes with a water filter while the K425 doesn’t have a water filter.

Most of the other features and designs look about the same but there are a few differences you should know before concretely deciding between the two.

Keurig K425 vs K475 Comparison Overview:

In a nutshell, here is what makes the K475 the “upgraded” model of the two:

• K475 includes a water filter starter kit (K425 does not)
• Includes 2 extra water filters
• 6 sample K-Cup pods (vs. 24 in the K425 kit)
• No reusable My K-Cup filter in the K475 (included in K425)

Similarities:

• Both are part of the K2.0 line (so all K2.0 compatible accessories will work with these machines)
• The same 70-ounce water reservoir
• Removable drip tray and water reservoir
• 2.4-inch full-color touch display screen Control panel
• Temperature and brewing strength controls
• Compatibility to K-cup, K-mug or K-carafe pods.
• Brews 11 different sizes
• Programmable clock.
• Auto on and Auto-off settings
• Three color options
• The faster brewing time of a cup in less than a minute.

Keurig 425

This is a slightly earlier model from Keurig 2.0 (K400 line) which has fewer features but has the basic and important coffee making features. If you have a water filter already, this is a great choice to save you some cash.

This model is an upgrade to previous models like Keurig 300 or 200 models. Despite the lack of a water filter, the K425 coffee maker is a popular model among the Keurig coffee makers.

You could also obviously get around the water filter necessity by simply always using pre-filtered water in your Keurig (using water from your built-in refrigerator dispenser will do the job just as well, it will just be slower to fill the reservoir).

Getting a sample kit of K-cup pods included in the box makes this another worthwhile investment in a coffee machine — being able to try a wide variety of coffee brands and flavors lets you determine your ideal morning cup!

Another aspect of this brewer that we quite liked is the flexibility to use the K carafe with this machine. While you’ll need to purchase the carafe and K-carafe pods (or a refillable one) separately, the ability to crossover between an instant single-serve brew and making a small pot for a gathering is a great feature.

There is also the option on K cups to adjust the brew strength. Being able to have a normal cup of coffee or make it a little stronger for “one of those mornings” is a nice little perk to a rough start day.

Installing this brewer in your kitchen is as simple as unboxing, hand washing the parts with warm, soapy water, re-assembling, and running a couple empty brews (no K cup pods installed) to clear out the internal water tank and dispense needle.

The main point to note is that while compatibilty lasts a long time, this model is officially discontinued by Keurig, so if you’re looking to buy this machine brand new you may need to search a little longer!

Pros

• Brews coffee in less than a minute.
• Brews 10 sizes
• Includes My K-cup reusable pod
• Programmable clock
• Temperature settings and strength control
• Easy to program

Cons

• No water filter kit
• Can’t connect directly to a water source
• Noisy

Keurig 475

The slightly improved model, as Keurig claims, comes with the addition of a water filter. If you would prefer a coffee machine with its own built-in water filter, the K475 is a great choice.

Keurig 475 offers high performance, easy operation, and great features for convenience.

Compared to other brands of coffee makers, this model is a high-quality coffee machine. It comes with a water filter handle and a few sample coffee pods.

If you’re buying this machine and hoping to go on a coffee tasting adventure in your own home, you’ll have to supply the coffee yourself. This machine doesn’t come with as many sample pods as the K425 model does.

Just like it’s K425 cousin, this brewer can also brew multiple sizes into the K carafe. And again, just like the K425, you’ll need to purchase the carafe itself and the pods (or a reusable K carafe pod) separately.

Need a stronger cup of coffee? This machine also offers the “strong” brew button, to let you get more caffeine in less time.

Installing this brewer in your kitchen is the same process as the K425, but with the additional step of getting the water filter ready for use, if you choose to add it to your brewer. You’ll want to follow the instructions for soaking the filter itself in cool water, then assemble the filter into the filter handle, and put it in the water reservoir before filling the reservoir with water. Run a couple of empty brews to clear the internal tank and needle and you’re ready to go!

Make a note:  while the K475 is still available for purchase as a new machine, the K2.0 technology is slowly being phased out. It is still supported but it is not the “latest and greatest” from Keurig, so you may have to check more closely to see if the newest accessories are in fact compatible with the K2.0 system.

Pros

• Comes with 5 temperature controls
• The brew sizes compatible with the coffee maker are between 4-30 oz
• Programmable clock
• Removable drip tray for easy cleaning.
• Strength control feature
• Easy adjustment of control settings

Cons

• No noise reducing feature
• There is no coffee filter
• The carafe is absent.

Outstanding Features

Keurig made these two machines with the same design with basically identical control displays, electrical systems, strength control auto on/off, etc. The following features are common on both Keurig coffee makers.

Settings and Controls

The 2.4-inch touchscreen control panel has settings for operating the coffee machine. It consists of brewing settings, temperature adjustment, timer, on/off, and other menus for easy control.

There is a strength control for adjusting the strength of the coffee. If you like strong or medium coffee strength, the setting works excellent.

Brew a cooler coffee when in a hurry by adjusting the temperature. Each pod size mugs, carafe, and cups have different settings in the menu.

Brew Sizes

Both the two Keurig coffee makers have 11 brew sizes that are compatible with three pods. You have options to brew a single cup with K-Cup pods. It selects from 4,6,8,10, and 12 ounces.

If you are using the K-Mug pod, the coffee maker allows you to choose between 14,16 and 18 ounces.

For K-carafe pods, it brews in 3 sizes of 22,26, and 30 ounces. The carafe pods are sold separately as accessories.

Removable Parts

In both the K425 and K475, there are 2 removable parts which are the drip tray and water reservoir. The drip tray when removed allows putting other mugs or carafe. It also collects the drips of coffee which remain after finishing the brew.

Removing the water reservoir makes refilling easier since the coffee makers cant connect directly to the water source. It also helps cleaning and descaling easier.

Brewing Times

In both Keurig coffee makers, you can brew a single-serve cup within 40-60 seconds. For stronger coffee, less time results in weaker coffee.

With the automatic brewing feature, the machines detect the pod and brew according to the time set for the specific size. This auto-brew feature is ONLY compatible with brewing a carafe, however, not a single cup.

Compatibility

The K425 and K475 are compatible with the following systems, including anything made for K2.0 brewers:

• K-Cup
• K-Mug
• K-Carafe
• K-Vue

Auto On and Auto-Off

These settings are important with the auto-off in default setting comes in handy. The setting turns the coffee machine after two hours of inactivity.

Once the reservoir has water, the auto on the setting reads the time set and starts brewing automatically.

Cleaning

It’s good to clean the coffee maker regularly or after 6 months for continuous amazing coffee flavor taste. The machines will remind you when the descaling process is due to be completed with a notification on the screen, which the company recommends to be completed with their special “descaling solution” which is available for separate purchase (this solution is compatible across all Keurig machines).

The deeper cleaning process is not that hard and it’s not done every day. With the water reservoir and drip tray removable, cleaning becomes easier and won’t take long.

On a daily basis, keep your machine free from dust build-up on the top and the controls, wipe up splashes and spills from the drip tray and brewer body, and remove any loose coffee grounds from the pod holder, if necessary.

On a regular basis, change the water filter (if applicable), wash the reservoir with warm, soapy water, and check for build-up on the dispensing needle and the bottom needle.

Conclusion

The K425 and K475 are medium coffee makers that cost a fair price. If you have a water filter, the K425 model will be suitable for your needs.

The price margin for the Keurig coffee makers is small but it’s your decision is yours to make.

Other Keurig coffee makers like K500 are a bit expensive but the K425 and K475  have the standard features to make great coffee without problems.

Generally, the K475 has been improved to perform extra than the K425. The difference is in few features in the box, but other features are identical.

It’s upon you to decide which Keurig machine K425 vs K475 is of greater value to you.
