The present device is indigenously prepared for all healthcare practitioners to support manufacturing in India. Additionally, it can be used in other sectors where there is a danger that contaminated air may cause respiratory disorders. Healthcare workers (HCWs) are at particular risk during pandemics and epidemics of highly virulent diseases with significant morbidity and a case fatality rate. These diseases include severe acute respiratory syndrome coronaviruses, SARS- CoV-1 and SARS-CoV-2, Middle Eastern Respiratory Syndrome (MERS), and Ebola. With the current (SARS-CoV-2) global pandemic, it is critical to delineate appropriate contextual respiratory protection for HCWs. All locally available components can easily be serviced and replaced, making it a cheaper device than all other Powered air-purifying respirators (PAPRs) available. The major components are the helmet and filter casing. There is moderate quality evidence for PAPR. Its use is associated with higher thermotolerance but lower mobility and communication ability scores. There has been a trend toward improved self-reported comfort with PAPR technology in low-quality observational simulation studies. Due to its two-layer filtering layers, it can be used in adversely contaminated environments. Field observational studies have shown no difference in infections among healthcare workers using the PAPR device compared to other matched ventilators. The PAPR was confirmed to have low mobility and high thermostability with audibility. However, more practical research is needed to explain the effectiveness of PAPR technology and provider satisfaction.
