Unverified87% confidenceFactTime unknown
HEPA滤芯等级H11过滤效率约95%、H13约99.95%、H14约99.995%，家用H13已足够，H14用于洁净室场景，级别越高对风机功率要求越高从而增加噪音和能耗

UnverifiedHEPA滤网等级H11过滤效率约95%，H13约99.95%，H14约99.995%；家用除PM2.5选H13足够，H14多用于医疗洁净环境，家用意义有限且更费风阻增加噪音94% similarUnverifiedHEPA等级标准:H11过滤效率≥95%、H12≥99.5%、H13≥99.95%、H14≥99.995%。家用防雾霾H12-H13足够，H14过滤阻力大会显著降低风量并增加噪音91% similarUnverifiedHEPA滤网等级对照：H11过滤效率≥95%（PM2.5够用），H12≥99.5%，H13≥99.95%（医疗级）；家用空调加装选H11-H12即可，H13风阻过大反而影响空调运行90% similarUnverifiedH13级HEPA滤芯的PM2.5过滤效率≥99.95%，H11级仅95%，对雾霾防护差异明显；但级别越高风阻越大，同CADR机型H13会更吵或更费电90% similarUnverified空调/新风机的HEPA过滤网选H11-H13级别即可满足家用除PM2.5需求，H13过滤效率≥99.95%，无需追求医疗级H14（阻力大幅增加会拖累风量和能耗）90% similar
