NIOSH認(rèn)證的其他防顆粒物防護(hù)口罩級別還包括：N95、N99、N100、R95、R99、R100、P95、P99、P100，共9種。這些防護(hù)級別都能夠覆蓋N95的防護(hù)范圍。 “N”表示不耐油（not resistant to oil），適合非油性顆粒物。 “R”表示耐油（resistant to oil），適合油性或非油性顆粒物，若用于油性顆粒物的防護(hù)，使用時(shí)間不超過8小時(shí)。 “P”表示防油（oil proof），適合油性或非油性顆粒物，若用于油性顆粒物，使用時(shí)間應(yīng)遵循制造商的建議。 “95”、“99”和“100”是指用0.3微米顆粒進(jìn)行測試時(shí)的過濾效率水平?！?5”表示過濾效率在95%以上，“99”表示過濾效率在99%以上，“100”表示過濾效率在99.7%以上。防塵面具有覆蓋口鼻，覆蓋口鼻、下頜2種，建議使用后者，相對較為舒適。河南防塵面具價(jià)格</p><p

1、化纖防護(hù)口罩：主要是化學(xué)纖維材料打造而成，沒有過濾作用、沒有防護(hù)效果，對塵土抵御都有限，自然沒有防護(hù)病毒的可能。 2、一次性防護(hù)口罩：由兩層無紡布加一層過濾布打造而成，可以對灰塵、部分PM2.5有抵御能力，但對細(xì)微顆粒、病毒細(xì)菌是沒有什么阻擋效果。 3、棉布防護(hù)口罩+普通濾片防護(hù)口罩：市場上售賣的PM2.5防護(hù)口罩本質(zhì)上就是這類防護(hù)口罩，實(shí)際上它對阻擋病毒、PM2.5的能力也是非常有限，只是比上面兩種稍微好一些而已。 4、一次性醫(yī)用防護(hù)口罩:在抵抗病毒上能達(dá)到70%的效果，是目前流行期間較常用、較適合大眾佩戴的防護(hù)口罩。 5、N95防護(hù)口罩:能夠抵御90%的病毒、細(xì)菌、PM2.5等，采取特殊納米材料制作而成的，對于依附在防護(hù)口罩面上的細(xì)菌病毒等也具有比較好的分解、殺滅效果，醫(yī)護(hù)人員用的比較多。河南防塵面具價(jià)格</p><p
