I am not sure I want to debunk something here - but I would like some more info on something a co-worker spends money upon. 'Bill" spends several hundred dollars a month on various things in health food stores... echinecia just being one. He recently said he has a 'filter' home that takes chlorine and florine out of his drinking water. It is both chlorinated and florinated by the minicipality. He pointed to our filter at work - but it takes out only particulate matter - not tiny atoms. I do not think that a filter will remove either of these elements - they are just too small, filters work on sizes measured in microns and atoms like these will slip through the mesh. Does anyone have any ideas here ... perhaps he may have some kind of catalytic filter that actually does do something.
