查看外包装是否标注碘值或比表面积参数，正规椰壳活性炭比表面积≥800㎡/g；无任何吸附参数标注、仅强调'黑炭天然'的产品多为低价竹炭或炭渣填充，吸附力不可靠

Unverified活性炭比表面积决定吸附能力，选择标注比表面积≥800㎡/g的产品，普通竹炭仅300-500㎡/g，除味效率差距明显80% similarUnverified标注'竹炭'但无比表面积/碘值参数的产品，实际多为低价填充料，除甲醛效果存疑，购买前应查看碘值（≥900mg/g为优质活性炭）78% similarUnverified看碘值指标而非仅看克重：优质椰壳活性炭碘值≥900mg/g，吸附能力约为竹炭的2-3倍，同等效果下椰壳炭用量可比竹炭少一半78% similarUnverified椰壳活性炭吸附能力（碘值≥800mg/g）显著优于竹炭（碘值约300-500mg/g），除甲醛除异味场景优先选椰壳活性炭而非普通竹炭78% similarUnverified椰壳活性炭碘值（吸附能力指标）通常在900-1100mg/g，明显高于竹炭的300-500mg/g，除甲醛应优先选椰壳活性炭而非竹炭，竹炭更多是营销概念78% similar
