MIT's mask study indicates that triple-layer masks are much safer than two layer masks.
I want to be safe when I have to go out for groceries, etc. So I looked for triple-layer masks sold in our community, as I prefer to buy local. I heard about a small business, "East 2 West Supply" that sells triple-layer masks at very reasonable prices. I bought some solid-colored masks and patterned masks. I ordered online in the evening, and the masks arrived the next day! They put it in in our mailbox. Love the customer service! They deliver fast and free! Additionally some spice samples came along free with the order! I'm very satisfied with the quality and comfort of the masks.
This is one of the best quality face masks I have seen in the market.
