The Bunn 20120.0000 disposable, flat-bottom coffee filter is used with Bunn System III coffee makers. It is made of heavyweight paper for resistance to tearing, and bleached by a chlorine-free method to ensure a low level of dioxin. The overall diameter is 15-1/8" and the base diameter is 5-3/8", and the tall sides reduce the risk of overflowing. A pack contains 250 filters, and the case contains two packs.

Disposable food service products are used to store, insulate, transport, prepare, and serve food and drink. They may be made of paper, plastics, or metal foil. Food service products for freezing items protect their contents from freezer burn, contamination, and drying. Microwavable food service products are safe for use to heat food in a microwave. Compostable food service products biodegrade about as fast as yard trimmings and food scraps, and disintegrate so that no large plastic fragments remain.

Bunn manufactures coffee makers, coffee grinders, water dispensers, paper filters, and other products for beverage systems. The company, founded in 1957, is headquartered in Springfield, IL.
