COVID-19 PeRSo Respirator PPE

Building PeRSo respirators for

NHS frontline staff

The COVID-19 pandemic has created a global shortage of personal protective equipment with significant challenges in the supply chain for adequate provision of typical multi-layered fabric face masks. The disposable face mask has limited success in the emergency environment with frequent failure during use and loss of appropriate protection against the virus whilst wearing. Indeed, many individuals fail to achieve an adequate fit and cannot wear the equipment.

Emergency service personnel are the frontline defence against the pandemic. To ensure success in delivering long-term sustained patient care a more effective and reliable solution to traditional face mask PPE is required. It must address the issues of poor fit and significantly increase performance to ensure protection against the COVID-19 virus.


Emergency service personnel have expressed a very positive response to the concept of a wearable filtered respirator based on initial concept design.  Communication is easier through a face shield with additional protection properties provided to the wearer and improvement in patient care. Use of similar positive pressure respirators within the health care sector in South Korea and Singapore has proven to dramatically reduce the infection rate of healthcare workers when compared with infection rates of healthcare workers using multi-layered fabric face masks in Spain and Italy.

Based on the initial designs carried out by the University of Southampton, Baynhams is pleased to offer the PeRSo range of respirators. For more information about the history of the project,
