CaliX - Refillable Single Serve Multi Layer Brewing Filter Capsule for Coffee with Keurig K-Cup Machines As seen on Food Network show Food Fortunes - Episode 6 - Meal or No Deal (04-13-15) CaliX is a new type of refillable brewing device for Keurig K-Cup machines. It was designed in the USA with the patented method of Multi Layer Brewing. By adding a secondary basket with holes at the top, the water level submerges all the grinds effectively steeping during the brewing cycle. Unlike all other devices, this creates a forced overflow drip and slows down the brewing process to extract all the delicious flavor. (U.S. Patent 8,808,778) CaliX has been tested and proven with 100% satisfaction at industry trade shows (Coffee Fest - NYC & Coffee Fest - St. Louis) to brew a much smoother, stronger and robust tasting cup of coffee with the same amount of coffee in a K-Cup. We won 3rd place in the new non consumable product category.
