   Indoor air quality (Wikipedia)

   “Indoor air quality (IAQ) is the air quality within buildings and structures. Poor indoor air quality due to indoor air pollution is known to affect the health, comfort, and well-being of building occupants. It has also been linked to sick building syndrome, respiratory issues, reduced productivity, and impaired learning in schools. Common pollutants of indoor air include secondhand tobacco smoke, air pollutants from indoor combustion, radon, molds and other allergens, carbon monoxide, volatile organic compounds, legionella and other bacteria, asbestos fibers, carbon dioxide, ozone and particulates. Source control, filtration, and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality. Although ventilation is an integral component of maintaining good indoor air quality, it may not be satisfactory alone. In scenarios where outdoor pollution would deteriorate indoor air quality, other treatment devices such as filtration may also be necessary. IAQ is evaluated through collection of air samples, monitoring human exposure to pollutants, analysis of building surfaces, and computer modeling of air flow inside buildings.”

   Health Benefits of Air Purification: A Systematic Review.

   “As people spend most of their time indoors, household air pollution is a significant yet often overlooked source of exposure. Existing evidence suggests that air purification is a promising intervention to mitigate these risks. This systematic review synthesized evidence from studies published between January 1990 and August 2025 on the effectiveness of air purifiers for improving the indoor air quality and mitigating health impacts. We also assess the cost-effectiveness and identify major limitations in current research. The findings demonstrate that air purifiers significantly reduce indoor pollution levels, leading to substantial respiratory and cardiovascular benefits, particularly in high-risk populations. However, evidence of neurocognitive outcomes remains limited. Despite heterogeneity in study designs, air purifiers represent a potentially cost-effective strategy for mitigating the adverse effects from air pollution. Standardized device certification, supportive policies to improve access, and continued research to optimize intervention strategies are warranted for the future.”

   Effects of indoor physical environment and psychosocial stress on work performance in a Thai academic setting.

   “Multiple linear regression analyzed relationships between these factors and three performance domains: task performance (TP), contextual performance (CP), and counterproductive work behavior (CWB). While TP was negatively associated with male gender (β = -0.14, 95% CI: -0.26 to -0.03), CP was significantly hindered by perceived stagnant air movement (β = -0.07, 95% CI: -0.12 to -0.02) and facilitated by adequate privacy (β = 0.06, 95% CI: 0.01 to 0.11). Furthermore, high-risk effort-reward imbalance was a strong predictor of lower CWB scores (β = -0.26, 95% CI: -0.45 to -0.07), indicating that highly stressed individuals engaged in more frequent counterproductive behaviors. These findings demonstrate that physical and psychosocial factors are significantly associated with specific performance dimensions. Specifically, poor air movement and a lack of privacy are linked to lower contextual performance, while work stress is positively correlated with counterproductive behavior. Consequently, institutional policies should prioritize improving ventilation, enhancing workplace privacy, and balancing effort-reward structures to optimize staff productivity and well-being.”
