Received these masks today. They are the standard 3-layer blue masks you see everywhere, with elastic ear loops. Made of non-woven fabric, not washable, disposable instead. I have read many articles which say these masks are good for 4-8 hours in normal use, less in dusty conditions. It is important that you NOT TOUCH the interior of the mask when putting on or removing, otherwise it is contaminated and must be replaced. Received the shipment from California, it took about 2 weeks to arrive. Thank you
