I use these: Ekobrew Cup, Refillable Cup for Keurig K-cup BrewersI just tried putting some ground coffee in the accessory coffee holder. It was terrible. Grounds in the cup, etc. Don't have the manual any more so how does this thing work? Is there some filter I have to use?
No grounds get through, but you do end up with a little sludge in the bottom of your cup. If that bothers you there are mini-filters available, but I found them to be more trouble than they are worth.
