My K Cup Filter, Keurig's response to the heightened need to be more conscious to the effect of our trash to the environment.
A lot of Keurig users have shared the same sentiment that disposable K Cups, although one of the features that separates Keurig from other coffee makers, are somewhat hazardous to the environment because they're not biodegradable and unrecyclable.
My K Cup Filters are basically permanent filters that you can use with your Keurig coffee system. You can now put coffee grounds inside them, insert the filter in the coffee maker, then start brewing.
I for one, am now interested in buying my own Keurig B40 because of this. At first I did not want to buy one and start adding more disposable K Cups to land fills. But now, I can start to brew guilt free.
