Powered Air-Purifying Respirator (PAPR) Hood Mount

An ultra-low-cost respiratory protection system for doctors and health workers on the frontlines designed by Amrita

A PAPR (Powered Air-Purifying Respirator) is an air-purifying respirator that uses a blower to force air through filter cartridges into the breathing zone of the person wearing the respirator. This process creates an air flow inside a loose-fitting hood, providing a higher assigned protection factor (APF) than an N95 face mask. A PAPR can be used for protection during healthcare procedures in which hospital staff and doctors are exposed to greater risks of aerosolized pathogens like COVID-19.

Amrita Vishwa Vidyapeetham’s AMMACHI Lab engineers Ayyappan Ajan and Vishnu Jayan have designed a prototype of a hood-mounted PAPR that delivers 4 cu ft/min air into the hood. We are actively working with doctors and pulmonary experts from Amrita Institute of Medical Sciences to further test and refine the prototype so that frontline medical workers who are providing care for COVID-19 patients can be protected.
