I've never conducted an analysis, but it shouldn't do anything except remove any particulate matter larger than what the filter is designed to let past. I suggested a coffee filter because they are handy and, presumably, designed not to impart any flavor of their own to whatever passes through them. Unless the whiskey is unfiltered, it has already gone through a much more intensive filtering prior to bottling.
