Where to buy N95 masks

San Francisco Chronicle - - BAY AREA -

N95 masks, which can screen 95 per­cent of the small par­ti­cles found in wood smoke, can be bought at many hard­ware stores and drug­stores. To work cor­rectly, they must be com­pletely sealed around the nose and mouth, so they may not fit prop­erly on chil­dren or on men with fa­cial hair.
