H13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

Unverified过滤等级H13级HEPA对PM2.5去除率≥99.95%，H11级约95%；重污染地区（雾霾频发）选H13，但HEPA等级越高风阻越大，会拉低实际出风量并增加噪音和能耗93% 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92% similarUnverifiedHEPA滤网等级越高(H13/H14)过滤越彻底但风阻越大，同CADR下需更强风机导致噪音上升，日常防雾霾H12-H13已足够，无需盲目追求H1491% similarUnverifiedHEPA滤网等级对照：H11过滤效率≥95%（PM2.5够用），H12≥99.5%，H13≥99.95%（医疗级）；家用空调加装选H11-H12即可，H13风阻过大反而影响空调运行91% similarUnverified过滤等级选H11-H13 HEPA滤网即可，H13对PM2.5过滤效率≥99.95%已足够家用；盲目追求H14医疗级会显著增加风阻，导致实际新风量下降和噪音增大91% similar
