As I understand it, this is a process, not a filter, so it does not remove any matter from the water, it changes the PFAs into something else, presumably something that is not as harmful. Carbon filtration will remove any contaminants (e.g. Florida, chlorine) in your water through adsorption. For the money, you can't beat it.
