As of 2015, user reviews on Drugstore.com rate the EkoBrew Cup as the top reusable K-Cup filter. With more holes than most of its counterparts, it directs water flow to a larger area of grounds, making a bolder cup of coffee.
The EkoBrew K-Cup filter makes a quality cup of coffee regardless of how coarse or fine the grind. Some of those who give the product high marks in general note its solid construction and the fact that it holds more coffee grounds than many of its competitors. Although coffee grounds occasionally become packed at the bottom of the filter, they are easily removed with forceful water spray.
