Do you recommend using a metal filter?

Every AeroPress coffee maker comes with 350 paper AeroPress micro-filters. We do not manufacture or sell filters for use in AeroPress coffee makers made of other materials such as metal. We were originally planning to include a metal filter with each AeroPress coffee maker 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 micro-filters are 100% compostable along with the coffee grounds and they retail for very little 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 our limited one year warranty does not cover operation with a filter made by another company or damage to the AeroPress coffee maker caused by use of such a filter.
