“…The assigned protection factor (APF) serves as the basis for determining the level of protection provided by masks, as stipulated in the recommended China national standard GB/T 18664-2002, "Selection, Use, and Maintenance of Respiratory Protective Equipment" (15). The APF refers to "a respiratory protective device or class of respirators that, when used correctly, is expected to reduce the concentration of air pollutants to an acceptable level" (16)(17)(18). The Occupational Safety and Health Administration of the United States (OSHA) standards explicitly state that "APFs are effective only if the employer implements an ongoing respiratory protection program that includes training, fit test, maintenance, and usage requirements" (19).…”

IntroductionRespirators chosen based on their assigned protection factor (APF) enable wearers to effectively reduce particulate matter concentrations to safe levels when used correctly. As a crucial factor in achieving the intended APF, the fit test has become a necessary procedure in respiratory disease protection.MethodsThis study involved 225 participants who underwent a fit test using two reusable types of half masks and two types of full masks. Condensation nuclei counting (CNC) and controlled negative pressure (CNP) were performed.ResultsThe results revealed that the passing rate of full masks was higher compared to half masks. Specifically, the passing rate for the half masks and the full masks were 84.7 and 91.6%, respectively. Gender exerted a statistically significant effect on the passing rate. Nevertheless, age, educational background, and training exhibited relatively negligible effects. Certain movements, such as facing forward, were identified as key actions with strong correlation. Additionally, talking was considered a key action with a high failure rate due to instantaneous leakages. Most participants failed at the initial step of CNP, but nearly all of them passed the fit test using CNC.DiscussionTherefore, putting on full masks, especially for women, provides optimal protection during work. Furthermore, attention should be given to the displacement and deformation of the respirator during the key actions. When it comes to fit test methods, CNC was found to be more practical and comprehensive compared to CNP. Moreover, additional physiological characteristics, such as double chins, could be explored as potential influential factors.

Introduction. COVID-19, a respiratory droplet-transmitted disease, has claimed approximately 7 million lives worldwide, partly due to a shortage of Personal Protective Equipment (PPEs) needed for prompt patient care. This study was done to assess if the locally developed Aegis Mark II Powered Air Purifying Respirator (PAPR) can fill this need in terms of usability and filtration efficacy.Methodology. The battery life was recorded in a controlled environment by running the PAPR continuously on low and high settings. To test usability, participants were allocated to three groups (commercial PAPR, Aegis Mark II, and Aegis Mark I), then participated in a clinical simulation while wearing the PAPR, and answered a questionnaire regarding their satisfaction with the PAPR. Filtration efficacies of the commercial PAPR and Aegis Mark II were compared in a controlled environment (acrylic box) by measuring the number of aerosolized NaCl particles inside the PAPR compared to outside the PAPR.Results. The Aegis Mark II PAPR's 20,000mAh rechargeable Lithium battery pack lasted for a mean of 11 h and 34 min (SD 16 min), and 8 h and 34 min (SD 38 min), for low and high flow blower settings, respectively. The mean charging time was 2 h and 20 min (SD 19 min) using a Fast Cellphone Charger (2.4 Amps). Participants reported higher satisfaction with the Aegis Mark II compared to the commercial PAPR in terms of factors affecting residency and education use and communication effort (n = 30, overall mean = 7.86 ±1.81) (Table 1), comfort (n = 8.52, overall mean = 8.52 ±1.63), and PAPR care (n = 30, overall mean = 7.76 ±1.75). The mean particle counts inside the hood of the Aegis Mark II PAPR and Commercial PAPR showed that PM2.5 (5.7 and 6.2), and PM10 (6.2 and 6.6) values were within acceptable Ambient Air Quality Standards. Conclusion.The locally developed Aegis Mark II PAPR displayed a high degree of protection comparable with commercial PAPRs. Its battery life was adequate. It was highly conducive to training and clinical work while being comfortable to use and maintain. It can provide a high degree of protection and alleviate the logistical strain during pandemics and public health emergencies.
