The Fastest Home Coffee Makers in America, now with an updated design. Speed Brew Coffee Makers can brew 10 cups of coffee in about 4 minutes because they store hot water in a stainless steel commercial grade tank allowing them to brew coffee on demand. They’re always on your counter, always plugged in and always ready to brew the perfect cup of coffee. Taller funnel - Our funnel is engineered to accommodate BUNN filters which are ¼ Inch taller than other filters. This unique design allows for the quick flow of water and prevents overflow of coffee grounds. Tank - Compared to the other home coffee makers that “burp” water over your coffee grounds as it boils, our tank keeps 70 oz of water at an instantly brew-ready temperature.
