I don't think it will melt, but I read that "almost all commercially available plastics that were tested leached synthetic estrogens...some BPA-free products actually released synthetic estrogens that were more potent than BPA." I did more research and now I'm looking for a simple pour over brewing device that works with a paper filter. I keep getting close to finding something, but finding one that uses regular paper filters (cone shaped is fine) is taking a while. I keep finding ones that use a filter with little holes punched in it, or the thinnest of any paper filter, or that the Chemex filters are "different than standard paper filters...quite thick..." I read a study somewhere that said paper filters remove something that may be harmful, and I want to make sure I get a coffee maker with common paper filters.
