Guest guest Posted February 3, 2006 Report Share Posted February 3, 2006 Hi , I spoke with a representative from the company. He explained how the filter is actually safe. First of all he said the half life of the hydroxyl radicals and superoxide ions is very short, even when breathed in - seconds. They are in a very unstable form and will combine with other elements to make water, if they don't attach to a contaminant. These substances seek out contaminants in the air and when they attach, it neutralizes the radical and the contaminant drops to the ground also neutralized. Were you aware of this? jafa --------------------------------- Brings words and photos together (easily) with PhotoMail - it's free and works with .
