Keurig K45 Elite Review

Jennifer’s Rating: 4.4 Stars

The Keurig K45 Elite, although discontinued from the general big-box market, remains on the Amazon Bestsellers list which indicates that it is doing great at standing the test of time in durability and long-term use.

That being said it is more affordable than the K65 Special Edition and covers all bases except for being as programmable. With this review I hope to highlight some of these things that put it on that Bestseller’s list as well as kept it there too!


The Keurig K45 Elite Single Cup Brewing System is a nice size. The removable reservoir holds 48 oz. The power cord is about 4 feet long.

Approximate measurements:

13 ” in height, 9.8 ” wide and 13.3″ in depth

Weight: 0.96 lbs

What’s Included?

In addition to the brewer you will also receive a sampler pack of 12 K-cups and a water filter. plus cartridge. Pretty much what is shown in the top photo. Use of the water filter is strictly optional but recommended for better tasting coffee. Periodically the cartridge will need to be replaced.

Also included is a start guide and a 1 year manufacturer’s warranty.

Ease of Use

The Keurig K45 Elite is one of the “classic” 1.0 series that uses K-Cups, and also the reusable My K-Cups in which you can fill with your own grounds. 

I’m pleased to report in this review the short learning curve involved. One customer said her six year old grandson managed to crank out some hot cocoa with ease. So if you have kids don’t be surprised if they want to follow suit.

Here’s a quick walk-through of the control panel:

  • “Add Water” light turns blue in the event the reservoir is getting low.
  • “Heating” light turns red in the pre-brewing stage.
  • “Auto Off” light turns green, when activated to go off in two hours.

The brew holder (to accommodate the refillable k-cups-not included) can be temporarily removed as well. You can separate the funnel from the top part to clean (tricky, but doable.) To replace the holder line up the arrows so it snaps into place.

keurig k45 brewer water filter cartridgeThe semicircle-shaped reservoir has tabs on the side that snap into place on the left side of the unit. Also, the water filter can be inserted into the reservoir; if you’re not familiar with these, they sort of resemble a thermometer and have a dial at the top in which you can set it so you will know when to change the cartridge (the carbon-filled sachets that do the legwork of removing impurities.) Rinse your cartridges thoroughly first before inserting them brand new. If you are already a user of filtered water, this tool may be strictly optional.


I feel that the Keurig K45 is reasonably priced and when the cost of K-cups in addition is factored in it comes out to a pretty good deal when you consider the fact that you can use the refillable K-cups for your own grounds if and when you prefer.

In my research, I found that the black version had the lowest price, which is bad news for someone like me who gravitates naturally to unique color choices. At the time of a recent revision I am unable to locate my favorite color (rhubarb) Sad to have to report that:(

My feeling is that if you have your heart set on the rhubarb you may have to go up to the more updated K50 model which does have many similarities. It looks like this one is getting supplanted more in quantity by the K50 and 55.

Keurig K45 Elite Consumer Reviews and Ratings

Apparently the Keurig Elite has stood the test of time, having been on the Top 100 list for awhile now. One common opinion is that there is more flexibility than with the newer Keurig 2.0 models that have certain restrictions with grounds being used. A few customers commented that this model was the closest to one of the earlier models (B40).

The use of bottled or filtered water makes the carbon filter less of a necessity, although the filter unit can be removed, it needs to be done so carefully.  If you’re using something like the Brita pitcher, you may opt to do this. The filter unit is not a substitute for the descaling process as it is not designed to remove trace minerals…just fyi. This could explain why many buyers have commented that the taste has been great – water quality can be a considerable factor.

QuietBrew technology was cited highly; (some people have said it’s noisy, but this one is subjective, just like the taste of their coffee.)

In general, many customers alternate between the K-cups and the reusable filter cups- cost being one of them and eco-awareness another. Having so many choices to sample, but also being able to save money by purchasing coffee beans in bulk to be grinded later and used in the reusable My K-cups, lets you have your cake and eat it too.

Altogether I felt like the many positive reviews from consumers were justified and fair with regard to the K45.


The major positives:

  • The attractive color options: I for one LOVE that rhubarb one (Gosh, I wish my Keurig K10 came in that pretty magenta shade!) 
  • The addition of the water filter and cartridge bonus that is included which helps maintain water purity and taste.
  • It heats up fairly quickly and auto shutoff feature is good too.
  • Allows for the use of K-cups and the reusable My K-Cups-pretty much “open platform” without the restrictions present in the 2.0 Keurig models.


The few negatives to call attention to:

  • This particular Keurig model does not have a warming plate; this may or may not be a stumbling block for you (It wouldn’t be for me; I rarely leave a mug of coffee just sitting around) If you are someone with a busy or transient life who just likes to brew and go with your travel mug, it may be no big deal.
  • Secondly, another fly in the ointment is the lack of temperature adjustment; you pretty much have control over the brew size and strength but the hotness is pretty much stationary.

If you have ever taken your Keurig machine with you as in travel or work-related reasons (e.g. parties) , you may find that draining the internal water tank is not an option (the company website includes this in the fine print.) Just wanted to point that out so it would come as no surprise.
