Unverified采用H13级HEPA滤芯为耗材需定期更换，长期使用需将滤芯费用计入持有成本86% similarUnverifiedHEPA级滤网净化能力强但更换成本高（H13滤芯往往一年一换、单次数百元），若所在城市空气常年优良，选H11级+可清洗初效即可，避免长期高滤芯支出86% similarUnverified选带高效HEPA(H11-H13级)的机型PM2.5去除率≥95%，但HEPA阻力大需搭配更大风机功率，纯静电除尘净化率低于HEPA但滤网可水洗、长期成本低85% 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83% similarUnverified过滤PM2.5应认准H11-H13级HEPA滤网，H13级对0.3微米颗粒过滤效率≥99.95%；重污染城市优先选带初效+中效+H13三级过滤结构，可延长HEPA寿命81% similar
