Variations is particulate silver particle size with time occurs as well. Perhaps Frank or Ivan can address that issue, I'm not knowledgeable enough to comment. > > I don't think there should be a difference between a HVAC produced ion > and a LVDC produced ion.

If only a few PPM of silver particulate are present then these particles have a good chance of remaining stable. Roger
