01 Filter Papers

Our flat bottom papers have been bleached using a chlorine free bleaching process. Please see Filtropa for more information about the filter papers and the process. This 01 size (also called 1K) fits nicely into 1-cup filter cones and our now-discontinued small ceramic filter cone (9cmØ).

40 fliters per pack.

We also sell 02 size and 04 size papers if you need a larger filter paper.
