Particulate matter (PM) is widely recognized as a major air pollutant with significant impacts on human health, highlighting the need for accurate monitoring. In developing countries, low-cost sensors are crucial accessible PM monitoring, but their accuracy and reliability must first be assessed. This study benchmarked Alphasense OPC-N3 Next through laboratory field evaluations. Laboratory tests were performed in controlled conditions HEPA-filtered at low humidity varying concentrations of water droplets from nebulized deionized water. A 27-day Cienfuegos, Cuba, provided additional insights into real-world performance. The showed susceptibility to perturbations was more affected by outliers (especially PM10), relative humidity, interference aqueous aerosols. contrast, sensor demonstrated superior stability, lower noise levels, consistent performance across different environmental conditions. Despite substantial price difference, both valid measurements. Additionally, produced lognormal concentration distributions during campaigns. feature could aid addressing calibration stability challenges commonly associated situ methods. While measurements affordable not perfect, they sufficiently reliable supporting quality assessments resource-limited settings.
