Review: K Cup Injector for Keurig Brewers - Reuse Your K Cups

Review from Single Serve - Coffee Pod ReviewsIMG_5669.jpg
The Handmade K Cup Injector and reused K Cup.

The K Cup Injector allows you to reuse your spent K Cups by refilling them with ground coffee, and then using the K Cup Injector top to seal the K Cup make a cup of single serve coffee. We've been testing out this home-made device for the last week purchased on Ebay, and it works surprisingly well. "Well" however means - a bit of a mess when making a cup of single serve coffee, because with each use you have to clean out coffee grounds, rinse the spent K Cup, and also wash the K Cup Injector.

Now we understand mess for the sake of being a little more eco-friendly, and the K Cup injector does hit the spot. In a way, it's very much like the My K Cup Reusable Coffee Filter, allowing you to just use ground coffee, and now throw out plastic K Cup after plastic K Cup. But there is a price, as we said mess and also cross-contamination of the coffee from the previous cup. Unlike the My K Cup Reusable Coffee Filter, you'll be using the same paper filter with the K Cup, and you'll also have to match the extra-bold K Cup filter or the regular K Cup filter with the grind you want - etc.

The amount of variable here is also staggering because of the grind, the filter paper in the K Cup, and the amount of water you want to use in each cup of single serve coffee using the Keurig model you have. There's also a claim of better extraction with the K Cup Injector, which you can read about in our earlier post here. We didn't find extraction to be any worse or any better given our testing with both the K Cup Injector and the My K Cup Reusable Coffee Filter.

Here's how the K Cup Injector works:

The K Cup Injector comes ina box with a menacing cartoon.
The inventor may have had too much caffeine.

You'll get instructions and the K Cup Injector top.

The spray head has a bunch of wholes for better extraction.
We think the extraction is about the same as the My K Cup Reusable Coffee Filter.

A little more in depth look a the head of the K Cup injector.

You'll have to take the foil top off a used K Cup and fill it with your favorite coffee.

The finished product - a K Cup made from the top of the

You then put the K Cup Injected K Cup in the Keurig brewer of your choice.

Final Thoughts on the K Cup Injector



  • Quality of K Cup Injector is a okay - but it's not a polished product yet
  • Lots of mess when making a cup of single serve coffee

We think you'll enjoy getting a gadget like this for your Keurig Elite B40 Brewer, Keurig B50, Keurig Special Edition Ultra Elite B60, Keurig B70 Brewer, Breville BKC600XL Gourmet Single Cup Brewer, and other Keurig K Cup brewers if your a bit of a tinkerer and single serve coffee hobbyist. We don't recommend this for the feint of heart, as the results can be mixed.

The coffee produced using the K Cup Injector was either on par with the My K Cup Reusable filter, or we didn't get a good extraction from cup to cup. We did get one grind and one set of consistent coffees after a bunch of bad cups. You're going to need to get motivated to find your sweet spot if you use the K Cup Injector, and be prepared for a lot of trial and error just like with the My K Cup Reusable Coffee Filter.

Right now you can purchase the K Cup Injector only on Ebay.

Jay, the injector fits the My Kcup doesn't it? Might it improve extraction with the My Kcup due to the better dispersion of water? If so that would be another use for the device.
