UnverifiedPM2.5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89% 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84% similarUnverifiedPM2.5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83% similarUnverified去除PM2.5和粉尘必须选带真HEPA滤网（H11级以上）的机型，纯负离子机型对颗粒物去除能力弱且会产生臭氧83% similarUnverifiedH13级HEPA滤芯的PM2.5过滤效率≥99.95%，H11级仅95%，对雾霾防护差异明显；但级别越高风阻越大，同CADR机型H13会更吵或更费电83% similar
