Airborne transmission is one of the major routes of respiratory infections and ranks in top ten causes of death worldwide. People spend more than 90% of their lifetime in indoor environments. Poor indoor air quality can cause adverse health impact and disease outbreak, particularly in healthcare facilities (e.g., elderly homes) where patients are vulnerable. The filtration technology is the most viable method for air purification and disinfection in healthcare facility. Yet the existing commercial air filtration devices have limitations such as recontamination and microbial emission from contaminated air filters. To tackle the problem, new coating was developed to provide filters a sustained antimicrobial and filtration functions. An optimized antimicrobial particulate air filters is capable of 95% reduction in viable microorganisms by combining “release-killing” biocides, “contact-killing” reactive dyads and anti-adhesion polymers to target different cellular sites in the microorganism along different inactivation pathways. This work evaluates indoor air quality (i.e., bioaerosol, particulate matters and volatile organic compounds (VOCs)) and the effectiveness of antimicrobial particulate air filters. Computational fluid dynamics (CFD) simulation was used to determine the best placement of air purifiers for a wardroom configuration and dynamics. The results showed that the application of antimicrobial particulate air filter in healthcare center mitigated indoor air pollution, thus improving the elderly home residents’ health conditions.
