Unverified室内空气质量参考阈值：PM2.5＜35μg/m³为优、CO2＜1000ppm、甲醛＜0.08mg/m³（国标GB/T 18883 1小时均值0.10mg/m³，新国标0.08）、TVOC＜0.6mg/m³85% similarUnverified改善室内CO₂标准路径：先用监测器测出峰值时段和浓度→＜1000ppm仅需定时开窗；1000~1500ppm加装机械新风；持续＞1500ppm需评估新风换气量是否匹配房间人数（每人约30m³/h）75% similarUnverified室内空气甲醛安全限值为0.1mg/m³（GB/T 18883标准，密闭12小时检测），除味除菌类需求可关注异味主观感受，但除甲醛需求应以此数值作为治理目标和验收标准74% similarUnverified判断新房是否达标应以国标GB/T 18883室内空气质量标准为准：甲醛≤0.08mg/m³(0.1mg/m³为封闭12小时的旧标准)，TVOC≤0.6mg/m³；报警阈值可自定义的机型才能按婴儿房更严标准设置72% similarUnverified臭氧浓度选择需按空间面积匹配：家用除味除螨选择200-500mg/h，20㎡以下房间足够；50㎡以上或车库、仓库需1000-3000mg/h工业级机型72% similar
