Unverified82% confidenceDecision RuleTime unknown
PM2.5截留率≥90%且透气率≥50%的产品才兼顾防护与通风，单看截留率≥99%的HEPA级窗纱通风量会骤降到不足30%，导致室内闷热

UnverifiedPM2.5去除率要看是否配H13级HEPA滤网(去除率≥99.95%)，而非仅初效+中效；纯热交换新风若无HEPA滤网，雾霾天净化能力有限，需搭配独立净化滤芯77% similarUnverifiedPM2.5去除率要看是否配H13级HEPA滤芯（一次性过滤效率≥99.95%），静电集尘式虽免换芯但对细颗粒物去除率通常低于90%且产生臭氧76% similarUnverified过滤PM2.5需选静电熔喷布材质（HEPA级），普通空调防尘选无纺布即可；熔喷布克重20-30g/㎡兼顾过滤与透气，超过40g会明显阻碍出风72% similarUnverified静电集尘板（ESP）的PM2.5一次通过集尘效率通常为85%-95%，低于HEPA的99.97%，若家中有过敏性鼻炎或哮喘患者，建议选择静电集尘+末端HEPA的混合结构而非纯静电机型68% similarUnverified防雾霾纱窗在提升PM2.5过滤效率的同时会明显降低通风量和透光率，对通风需求大或采光本就不足的房间不建议全窗安装68% similar
