Indoor air quality (IAQ) has a substantial impact on public health. Since the beginning of COVID-19 pandemic, more employees have worked remotely from home to minimize in-person contacts. This pilot study aims measure difference in workplace IAQ before and during pandemic its employees’ The levels fine particulate matter (PM2.5) total volatile organic chemicals (tVOC) were measured offices at homes while working using Foobot monitors. frequencies six sick building syndrome (SBS) symptoms evaluated each period monitoring. result showed PM2.5 households significantly higher than office for all participants (p < 0.05). exceeded health-based annual mean standard (12 µg/m3), whereas 90% compliance. tVOC below (500 µg/m3). We also found frequency SBS observed as was worse home. suggested that might detrimental health due poor providing interventions remote should be considered.
