Look at the photo, does it suit anyone? I figured the charcoal filter would filter out all the contaminants and prevent the contaminated water from seeping into the ground coffee. so that the water after the filter is clean and clean, so why a rust-colored stain on the filter and sediment after the filter in the water tank? Does this mean that impurities are getting into my coffee through the filter? satisfied or convinced that these filters work as described.
