This is a very similar process, chemically, to the ARTI filter. This guy is looking for financing and has applied for a patent. EYI already has a $210 million contract and ARTI has US and World patents, a producer, a shipper/ warehouse, etc. EYI has the jump on this guy. EYI will be selling very soon. But you do what seems best to you! Oh... and the United Nations already is giving away iron oxide based arsenic removal technology.
Good luck,
