It is now possible to make your beloved AeroPress even better. The natural oil from coffee beans contribute greatly to the taste of your coffee. Unfortunately, paper filters block those oils (while also potentially containing chemicals). The ULTRA filters allows those oils through without allowing any grit or grind. The ULTRA filter is versatile: It is great for brewing techniques that call for a fine grind size and a steep time of 3 minutes or less. At the same time, it will still work with larger grinds such as those you'd use for a french press. This is the filter to go with for a turkish or espresso type brew. The ULTRA is reliable: it's designed to perfectly fit older and newer generation AeroPress Coffee makers.

If the filter breaks, stains, or gets damaged just let us know and we'll replace it with a new one. We love the AeroPress becauses it's easy to clean. Our filter is no different and adds only seconds to your clean up time.
