指标越多越贵但传感器互相干扰、体积增大：温湿度+PM2.5+CO2+甲醛四合一已覆盖90%育儿需求；加TVOC、噪音、光照的七合一多为营销堆料，其中噪音光照对健康预警意义有限

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83% similarUnverified指标越全（甲醛+PM+CO₂+TVOC+温湿度）价格越高且传感器互相干扰概率增加；家用普通场景选甲醛+PM2.5+温湿度三项足够，全能机主要面向办公室/母婴间83% 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一77% similarUnverified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76% 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75% similar
