Unverified除宠物异味必须看活性炭重量，颗粒活性炭≥1.5kg才有持续吸附氨气/硫化物的能力，仅靠薄层蜂窝活性炭或涂层滤网的机器3个月后除臭效果断崖式下降84% similarUnverified宣称'甲醛+除臭双效'的活性炭包对宠物异味针对性弱，甲醛吸附型改性炭孔径设计不同，除宠物氨味应选专用除味炭而非家装甲醛通用款82% similarUnverified碘值≥900mg/g的椰壳活性炭除臭效果显著优于煤质炭，宠物异味场景优先选椰壳活性炭并注明碘值参数82% similarUnverified除宠物异味（氨气、粪便味）的核心是活性炭重量，颗粒活性炭需≥1.5kg才有持续吸附力，蜂窝状或喷涂活性炭（<500g）除味仅能维持2-3个月，闻着'刚开机有效、一周后失效'就是碳量不足81% similarUnverified活性炭本身无法杀菌，对细菌代谢产生的持续性异味只能吸附不能根治，宠物排泄区应'活性炭+定期清洁+益生菌除臭剂'组合使用79% similar
