We recently began looking for a replacement for the nylon french press screens that we stocked for so long. Our supplier on that item went out of business, so I asked another manufacturer to look into this. They sent samples of both nylon and stainless steel material to test. We added the material to the filter assembly of a french press and compared the flavor and the amount of sediment each was capturing. The stainless steel mesh seemed to do a better job on both counts, reducing that over-extracted flavor that you can get from french press with too much sediment. I am not sure when I can offer these, but it ought to be no more than a few months. The previous filters were nylon on a plastic frame, I think these will be stainless steel mesh.
