Abstract

Reed diffusers are widely used as an indoor scenting source, in which aromatic components are thought to have sleep-improving and anxiety-relieving effects. Nevertheless, it is crucial to consider the potential health impacts associated with certain components in aromatherapy. This study aims to comprehensively explore the impact of reed diffusers on indoor air quality. We analyze the composition of gas-phase volatile organic compounds (VOCs) based on emission tests of a typical reed diffuser in a full-scale chamber. The observed top three VOCs are linalool acetate, linalool, and α-pinene, with linalool acetate accounting for 31.4%–43.6% of the total at 25°C. A physics-based model is then developed to characterize VOC emissions from a reed diffuser, and the key transport parameters are determined. Independent experiments validate the reliability of model parameters. Computational fluid dynamics simulations further demonstrate that reed diffuser position significantly impacts VOC distribution, which is essential for sophisticated exposure assessment.
