The OEM k-cup v2 reusable filter allows you to use your own coffee in k-cup pod style single serve brewers. This model has a top with a ‘double seal’ that also locks on with a slight turn. In fact, the overall quality of this product is clearly a step above most of the 3rd party offerings, making this a case where you do get what you pay for, in our opinion at least.
Conclusion: Best Reusable K-Cup Filter.
