HEPA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

Unverified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% similarUnverifiedHEPA等级越高（H14）阻力越大，同风机下出风量下降、噪音上升、能耗增加，家用净化器H13是效率与风量的最佳平衡点，H14多用于医疗/洁净室88% similarUnverified空气净化器HEPA滤网选H13级（过滤0.3μm颗粒≥99.97%）即可满足家用除PM2.5，H14及以上（医疗级）会增加风阻降低风量，家用无必要88% 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87% similar
