Improving Hospital Air Quality With a Nano-Ag/Chitosan-TiO2 Filter System and Cloud-Based Monitoring
Improving indoor air quality (IAQ) in hospital environments protects vulnerable patients and healthcare professionals from airborne pollutants and pathogens. This study integrates three interconnected components: a comprehensive analysis of hospital IAQ, an evaluation of a nanosilver/chitosan–titanium dioxide (nano-Ag/CS-TiO2) filter, and an assessment of real-time monitoring using a cloud-based platform. The nano-Ag/CS-TiO2 filter demonstrated enhanced efficiency in reducing a broad spectrum of pollutants, including particulate matter (PM2.5 and PM10), carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), and microbial aerosols. Measurements were conducted across different hospital zones and timeframes to reflect typical hospital operations and assess the adaptability of the proposed solutions. The study further addresses the long-term use of nano-Ag/CS-TiO2 and underscores its advantages over existing filtration methods. Cloud-based monitoring provides real-time data, allowing for timely intervention for IAQ, particularly in high-risk areas like negative pressure isolation rooms. The finding in a negative pressure isolation room demonstrated significant improvement in IAQ postinstallation of the nano-Ag/CS-TiO2 filtration system. The integration of nano-Ag/CS-TiO2 filtration and real-time monitoring supports compliance with World Health Organization (WHO) IAQ standards. These findings highlight the potential for broader application in various healthcare settings, such as outpatient clinics and emergency departments. The study also ensures accuracy in pollutant detection, addressing the potential for false positives and negatives in cloud-based monitoring. This study highlights that a nano-Ag/CS-TiO2 filtration system can enhance IAQ in hospital settings by effectively removing air pollutants and inactivating airborne pathogens. This approach facilitates the development of evidence-based strategies for promoting healthier indoor environments in hospitals.
期刊介绍:
The quality of the environment within buildings is a topic of major importance for public health.
Indoor Air provides a location for reporting original research results in the broad area defined by the indoor environment of non-industrial buildings. An international journal with multidisciplinary content, Indoor Air publishes papers reflecting the broad categories of interest in this field: health effects; thermal comfort; monitoring and modelling; source characterization; ventilation and other environmental control techniques.
The research results present the basic information to allow designers, building owners, and operators to provide a healthy and comfortable environment for building occupants, as well as giving medical practitioners information on how to deal with illnesses related to the indoor environment.
