A coffee filter ring that comprises a retaining ring adapted to fit within the coffee filter paper in the coffee basket of a conventional automatic drip coffee maker. The ring is sized and shaped so that it can be placed on top of a second filter paper and holds the second filter paper in place essentially sealing off the coffee grounds being held by the first coffee filter paper, thereby preventing the coffee grounds from spilling out of the coffee filter basket into the coffee pot while the coffee maker is brewing the coffee. The coffee filter ring is sized and shaped to fit the middle to lower portion of the filter basket and is split with an outward springing action to enable it to adapt to the size of the basket and conform to the coffee filter papers and coffee grounds as they become moist from the hot water from the automatic dripping system.
