I don't profess to know anything about infra red rays, be they near, far or somewhere inbetween.
What i do know is that a search on the web for 'far infra red' or 'bioceramic' returns loads of info about them and a multitude of products in which they are used. Indeed there are a number of domestic water purification systems amongst the results which contain bioceramics emitting far infra red rays.
