Do you recommend using a metal filter in the AeroPress?

Every AeroPress coffee maker comes with 350 AeroPress paper filters. We do not manufacture or sell filters for use in the AeroPress made of other materials such as metal. We were originally planning to include a metal filter with each AeroPress but when we conducted blind taste tests comparing paper filtered coffee with metal filtered coffee, the paper filtered coffee always won. We also learned using a paper filter is healthier because it removes diterpenes from coffee and diterpenes are potent agents that raise your bad cholesterol. Metal filters do not remove diterpenes. AeroPress paper filters are 100% compostable along with the coffee grounds and they retail for less than a penny and a half each so they are gentle on the environment and your wallet. That said, while we think that paper filters brew better tasting coffee, taste is certainly personal so people should brew their coffee the way it tastes best to them.

There are many companies that manufacture filters designed for use in the AeroPress coffee maker made of other materials, particularly metal. We do not object to these other companies selling their filters but none of them can legally use our AeroPress trademark. It is important to note that the AeroPress limited one year warranty does not cover operation with a filter made by another company or damage to the AeroPress caused by use of such a filter.
