防護口罩分為兩類：工業(yè)用顆粒物防護口罩（比如N95）和醫(yī)用防護口罩。對于普通人來說，兩種口罩都可以使用。1.工業(yè)用顆粒物防護口罩。通常執(zhí)行美國N95、中國KN95、歐洲FFP2、日本DS2等標準；這些標準是指阻隔直徑大小約為微米的顆粒物。而飛沫指直徑大于5微米的氣溶膠（顆粒物），因此普通人也可以使用工業(yè)用顆粒物防護口罩。測試標準稍有不同，測試的顆粒不同，F(xiàn)FP2是油性與非油性都可過濾，美國有油性的R和P標準，中國有油性的KP的效率達到95%(FFP2為94%)。數(shù)字越大，dai表過濾能力越強，如N99、N100、FFP3標準的口罩，也有阻隔效率差一點的，比如KN90和FFP1口罩。大家可以推薦N95、KN95等口罩，KN90次之。2.醫(yī)用防護口罩不僅滿足對非油性顆粒物至少95%過濾效率要求（但不一定都獲得了N95認證），還具有阻隔血液或傳染性體液噴濺的能力，更適合醫(yī)務(wù)人員臨床使用。例如3M1860/1860s、9132等。 </p><p style="text-indent:25px">醫(yī)用防護口罩（也就是我們常說的N95，KN95防護口罩），醫(yī)用防護口罩適用于醫(yī)務(wù)人員和相關(guān)工作人員對經(jīng)空氣傳播的呼吸道傳染病的防護，是一種密合性自吸過濾式醫(yī)療防護用品，防護等級高，尤其適用于診療活動中接觸經(jīng)空氣傳播或近距離經(jīng)飛沫傳播的呼吸道傳播疾病患者時佩戴?？蔀V過空氣中的微粒，阻隔飛沫、血液、體液、分泌物微滴等，屬于一次性使用產(chǎn)品。醫(yī)用防護口罩能阻止大部分細菌、等病原體，WHO推薦醫(yī)務(wù)人員采用防顆粒物的防護口罩，以防止醫(yī)院空氣中的傳播。醫(yī)用防護口罩符合GB19083-2003《醫(yī)用防護口罩技術(shù)要求》標準，重要技術(shù)指標包括非油性顆粒過濾效率和氣流阻力。一次性防護口罩的優(yōu)點：能夠保溫、可以吸水。</p><div
