检测指标越全越贵且体积越大：五合一（甲醛+TVOC+PM2.5+CO₂+温湿度）需集成多种传感器，牺牲便携性和电池续航；纯监测通风只需CO₂+温湿度即可

Unverified指标覆盖越全（甲醛+PM2.5+CO2+TVOC+温湿度）单个传感器精度反而可能被压缩且价格高，普通家庭抓住核心1-2项（新房重甲醛、雾霾重PM2.5、闷重CO2）比堆参数实用85% similarUnverified温湿度传感器集成度越高（含气压、光照、VOC）价格越贵且电池消耗越快，多数家庭仅需温湿度+光照即可满足空调/加湿/窗帘联动，VOC/CO2检测应单独选专用空气质量传感器84% similarUnverified指标全覆盖与准确性存在权衡：号称同时测甲醛+TVOC+PM2.5+CO₂+温湿度的千元内一体机，往往每项都用低成本传感器堆砌，单项精度不如专项设备。装修验收建议用专项甲醛仪，日常环境监测才选多合一83% similarUnverified检测种类越全（PM/甲醛/CO2/TVOC/温湿度六合一）单项精度反而越受成本妥协，专项治理（如只测甲醛）用单功能高精度设备更可靠83% similarUnverified传感器精度越高、指标越全（甲醛+CO₂+PM2.5+TVOC全测）价格越贵体积越大，若只为新房验收甲醛，选专业单一甲醛仪比全能便携机更准；只为日常看空气，多合一但精度一般即可80% similar
