Unverified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）87% similarUnverified过滤精度越高（HEPA H13级）风阻越大，会明显削弱出风量和制冷效率、增加压缩机负荷，家用挂机建议粗效+静电棉组合即可，追求H13以上应选带独立净化模块的空调而非改装滤网87% similarUnverifiedH13级HEPA滤芯PM2.5去除率≥99.95%但风阻大、耗能高、更换成本高；H11/H12级去除率95%-99.5%阻力小更省电。非重度雾霾地区H12足够，滤网分级(初效+中效+HEPA)可延长HEPA寿命87% similarUnverified过滤效率看HEPA等级：H11约95%、H12约99.5%、H13约99.95%对PM2.5去除率。重污染地区（如京津冀冬季）建议H12-H13，但HEPA等级越高风阻越大，需搭配更强风机否则实际风量骤降86% similarUnverified空气净化器认准真HEPA H13级别（对0.3微米颗粒过滤效率≥99.95%），H11/H12效率仅95%-99.5%；标注'HEPA type'或'HEPA-like'的为仿制滤材，无国标认证，不建议购买86% similar
