This minimizes coffee grounds getting into your coffee. | Superior Taste - Paper filters remove most oils and micro coffee particles which cause coffee to turn bitter. Metal and cloth filters can let these into your cup. | Eco-friendly & Made In The USA - Biodegradable and made from paper, a renewable resource. All manufactured right here in the US. | Easy Clean Up - Disposable filters mean that you can toss the grounds without needing to clean out a metal filter.
