Unverified除甲醛/异味需看活性炭克重而非仅看有无，有效除醛滤网活性炭含量应≥500g，低于300g的复合滤网除醛能力仅为噱头，且吸附饱和后需及时更换否则会二次释放85% similarUnverified除甲醛需看甲醛CADR而非颗粒物CADR，二者是独立指标；有效除醛甲醛CADR应≥100m³/h，且优先选活性炭+改性锰系催化滤网，纯活性炭吸附饱和后会二次释放85% similarUnverified新房除甲醛必须看甲醛CADR(而非颗粒物CADR)，甲醛CADR≥300且滤芯含活性炭≥1kg才有实际效果，标称'除醛'但活性炭量少的机型基本无用85% similarUnverified除甲醛核心看甲醛CADR和活性炭重量，滤芯活性炭含量应≥1kg才有持续除醛能力；宣称除醛但只标注颗粒物CADR的产品，除醛多为噱头84% similarUnverified活性炭滤网的关键指标是碳含量（克重），普通净化器滤网活性炭约200-500g，除甲醛型需≥800g或采用改性活性炭（负载KMnO4等）；单纯颗粒物污染无需高碳含量滤网84% similar
