PAPR
POWERED AIR PURIFYING RESPIRATOR
Mohak Parikh

Identifying the need !
As the world saw the onset of rising coronavirus cases, the need for medical and
personal protective equipment saw a sharp rise in demand. PAPR was the need for the
hour for first responders and medical staff. Many medical equipment supply chains
experienced disruption causing the medical industry to depend on local or national
sources. PAPR was one such product that was not included in the portfolio of most
Indian companies in the field.
What is the purpose of PAPR ?
A Powered Air Purifying Respirator (PAPR) is a device used by medical personal,
firefighters, and other first responders. It takes ambient air contaminated with one or
more types of pollutants or pathogens, actively removes (filters) a sufficient proportion
of these hazards, and then delivers the clean air to the user's face or mouth and nose.
They have a higher assigned protection factor than filtering respirators such as N95
masks.
