Unverified75% confidenceTradeoffTime unknown
颗粒物+甲醛复合滤芯往往因甲醛层先失效而被迫整体更换，分体式(颗粒/活性炭独立)可分别更换更省钱，长期使用应优先分体设计

Unverified除甲醛需要大量活性炭滤芯，但活性炭吸附饱和后会二次释放，追求除醛的机型滤芯更换更频繁、耗材成本更高85% similarUnverified除甲醛与除颗粒物是两套滤材需求，一体机为兼顾两者往往在单项上妥协，且活性炭滤芯寿命短会拖累整体成本；若主需求明确应选专项优化机型83% similarUnverified除甲醛型（厚活性炭）和纯颗粒物净化型是权衡关系：除醛滤芯风阻大、颗粒物CADR会下降，且活性炭吸附饱和后会二次释放，需比HEPA更勤更换81% similarUnverified带HEPA的除甲醛机型，活性炭吸附饱和后会二次释放甲醛，需比颗粒物滤网更勤更换，除醛能力与滤芯成本成反比权衡81% similarUnverified除甲醛的活性炭滤芯与除颗粒物的HEPA滤芯理想寿命不同（活性炭衰减更快），一体式复合滤芯只能整体更换，长期除醛需求下滤芯成本高于分体式滤芯机型81% similar
