Evaluating the impact of air purifier intervention on particulate matter concentrations in a traditional Chinese medicine therapy room using multiple approaches.

ABSTRACT: Traditional Chinese medicine (TCM) is a widely practiced holistic care system in East Asia. However, concerns have arisen regarding the health risks associated with smoke inhalation from moxibustion treatments for both patients and medical staff. Therefore, the aim of this study was to compare particulate matter (PM) concentrations in a TCM therapy room before and after installation of air purifiers. This study used multiple approaches to assess the impact of air filtration on PM levels and provided a more accurate evaluation. The first approach compared PM concentrations before and after implementation of air purifiers, which revealed significant reductions: PM₁ decreased by 16% to 72% (p < 0.01), PM_2.5 by 18% to 67% (p < 0.01), and PM₁₀ by13% to 49% (p <
