Well, we finally found one we like! After many requests of when are you going to do k-cups? We've got an answer! The EkoBrew refillable/reusable filter for Keurig k-cup brewers.
We've played around with some of these ourselves plus got some in the hands of our regular local customers and it appears everybody likes 'em.

Advantages over K-cups

Greener-reduce waste-make coffee not trash.
Fresher Coffee = Better flavor
Less expensive-buy coffee not packaging
More choices-any coffee we do!

Advantages over Keurig's own refillable "My K cup"

no filter holder replacement necessary
larger = holds more coffee = fuller flavor in the cup
spray cone distributes brew water across coffee surface better = better extraction = better flavor
mesh across bottom and only lower third of sides means brew water flows fully through coffee = better extraction = better flavor

*We suggest using a Foil Filter grind for the Eko-Brew filter. If you prefer an extra strong cup of coffee you may want to ask for a slightly finer (drip) grind and if you prefer a weaker cup of coffee with less fines in the cup you may want to ask for a slightly coarser grind than Foil. If the coffee is too finely ground your EkoBrew has the potential to back up and leak as there is only so much back pressure the pump and seals in k cup brewers can handle.

Special Price only $10.00

As we're pretty much selling these at our cost, (MSRP is $16.95) we really don't want to ship them by themselves. So, if you're looking just to pick up a couple Ekobrew units without our coffee, we recommend getting 'em from amazon.com (free super saver shipping over $35 if you don't have Prime) or directly from ekobrew.com (free shipping)
