UnverifiedHEPA滤网等级H13可过滤0.3微米颗粒物达99.97%，H11为99.5%，卧室及防霾用H13已足够，H14及以上多用于医疗/实验室场景，家用无必要90% similarUnverifiedHEPA等级H13可过滤0.3微米颗粒99.97%，H14可过滤99.995%，母婴场景H13已足够，H14会显著增加风阻导致噪音上升和风量下降，不必盲目追求89% similarUnverifiedHEPA滤网等级H13可拦截0.3微米颗粒物达99.97%，H12为99.5%，家用防霾防过敏H13即足够，无需追求H14工业级89% similarUnverifiedHEPA滤网等级H13比H12对0.3微米颗粒过滤效率高(99.95% vs 99.5%)，但阻力更大会降低CADR并增加噪音。日常防霾H12足够，过敏人群或防病毒需求才选H13/H1488% 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88% similar
