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

UnverifiedHEPA滤网净化效率越高（H13/H14），阻风越大，会明显削弱空调制冷/制热风量并增加压缩机能耗，家用制冷优先建议H11-H12平衡风量与净化95% 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）89% similarUnverified过滤等级越高（HEPA H13）风阻越大，会显著削弱自然进风量并加快风机能耗与噪音，普通城市环境用F7/中效滤芯即可平衡过滤与风量，不必盲目上H1388% similarUnverifiedHEPA滤芯的过滤效率与风阻成正比，H13/H14级过滤更彻底但风阻大导致同功率下CADR降低、噪音升高，日常防雾霾H12~H13已足够，无需为H14牺牲风量和静音88% similarUnverified过滤等级越高、越接近HEPA，风阻越大，空调制冷/制热效率下降越明显且噪音增大：家用挂机/柜机不建议直接加装H12以上HEPA，会导致风量骤减、内机结冰或电机过载88% similar
