Review (5/5): GREAT PRICE  !!!!! Use them like multivitamins... 1-a-DAY... Or more.
These masks are VERY easy to form fit over the nose. The snug overall fit is quite good for the purpose of filtering unwanted nastiness. All of this without being overly restrictive to breathing EVEN when double masking as is now suggested. At 6 cents each they are a WINNER.
