Mathematical modeling shows reduced reproduction number with PAPR use during pandemics, suggesting integration into public-health policy.

Key Points

This research aims to assess the effectiveness of Powered Air-Purifying Respirators (PAPRs) in reducing transmission during pandemics while maintaining personal freedom.
Developed an IoT-based management framework for PAPR use called PAPR Wearing-Status Networked Management System (PWS-NET)
Conducted scenario tests to evaluate real-time detection and management of PAPR wearing status
Utilized mathematical modeling to project the impact of PAPR usage on the reproduction number
Demonstrated that over 55% continuous PAPR use can lower the effective reproduction number from 2.0 to 0.9
Prototyped the system with successful operation of saved allowance time updates
Validated effective visual feedback for users regarding PAPR wearing status
