RE:Going to ZERO used 30 years in AsiaYes...that is the one fact that bothers me. Although I'm not sure we'd want to buy it from the Asians after the defective face masks they sent to us! Given a choice of supplier, do you think we'd want to enrich the folks who gave us covid19? Anyway, who's to say they're not using it now without FDA clinical standards. Clearly their food and water and health equipment standards aren't good enough. Or if they are, they won't send good quality to us.
