look at the photo, does anyone like it? so that water gets into the ground coffee. I expected the water to be clean and clear after the filter, so why is there a rust colored stain on the filter and settles in the water tank after the filter? Does this mean that contaminants will pass through the filter and end up in my coffee? Not very happy or convinced that these filters work as advertised.
