The Disk Coffee Filter is a reusable filter designed to be used with the Aeropress. This allows more oils and a fuller bodied cup of coffee when used with the Aeropress. The Disk eliminates the need for paper filters, which is especially convenient when travelling.
The Disk Standard produces a fuller body cup of coffee with a bit more fines. Thicker and should last many years of heavy use and is very hard to bend/damage.
The Disk Fine produces a very sweet clean cup of coffee with very little fines to none at all. It is thinner (1/3 of the Standard) and should be handled with care as bending/damage is more likely.
