Excess bitterness in coffee typically comes from over heated water, coffee fines (micro granules), and over extraction. The AeroPress Micro filters do their part by removing coffee fines and sediment from the brew, and so minimising excess bitterness. How to Use: Like any coffee filters, its recommended to rinse the filter with hot water immediately before use. This will removes loose paper fibres or flavours making their way into the cup.
Each pack contains 350 Micro bleached filters
