Unverified竹炭与活性炭本质都是碳吸附材料，活性炭因经高温活化孔隙率更高，同等重量下吸附能力约为普通竹炭的3-5倍，追求除味效率优先选活性炭而非竹炭79% similarUnverified椰壳活性炭比煤质活性炭孔隙率高、比表面积可达1000-1500㎡/g，吸附甲醛效率更高；竹炭比表面积通常仅300㎡/g左右，除味尚可但除醛能力弱，选除醛应认准椰壳活性炭79% similarUnverified竹炭孔隙率高于普通活性炭但吸附总量常低于椰壳活性炭，同等克重下椰壳活性炭综合除味能力更强，选购时优先看碳源材质而非仅看『炭』字77% similarUnverified活性炭净化效力看碳含量与孔隙率，家用除味优选含椰壳活性炭或竹炭的复合款，单袋净重≥200g才对新装修甲醛/异味有实际吸附意义，纯植物纤维填充的所谓'炭纤维'装饰袋净化效果基本可忽略76% similarUnverified活性炭吸附能力与碘值和比表面积相关，椰壳活性炭碘值通常高于竹炭，吸附异味效果更佳；商品标注比表面积＞800㎡/g为较优76% similar
