Our filter is ultra slim. The disc is also our most durable & easiest to clean filter. It's great for backpacking and travel. This allows more oils and a fuller bodied cup of coffee when used with the Aero Press. Eliminates the need for paper filters, which is especially convenient. The Coffee filter disk 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. Customized is available if necessary. Please contact us if you need more details about this product. Diameter: 2.4”.
