Performance of Four Consumer-grade Air Pollution Measurement Devices in Different Residences.

ABSTRACT: There has been a proliferation of inexpensive consumer-grade devices for monitoring air pollutants, including PM_2.5 and certain gasses. This study compared the performance of four consumer-grade devices-the Air Quality Egg 2 (AQE2), BlueAir Aware, Foobot, and Speck-that utilize optical sensors to measure the PM_2.5 concentration. The devices were collocated and operated for 7 days in each of three residences, and the PM_2.5 mass concentrations were compared with those measured by established optical sensing devices, viz., the personal DataRAM and DustTrak DRX, as well as the filter-based Personal Modular Impactor (PMI). Overall, the Foobot and BlueAir displayed the strongest correlations with the direct-reading reference instruments for both the hourly and da
