The disc Coffee filter Set includes both the STANDARD and FINE version of the disc Coffee filter. The disc Coffee filter is a reusable filter designed to be used with the AeroPressÂ® Coffee Maker. This allows more oils and a fuller bodied cup of coffee when used with the AeroPressÂ®. Eliminates the need for paper filter s, which is especially convenient when travelling. STANDARD: 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. FINE: 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.
