What is a PAPR?

A Powered Air-Purifying Respirator (PAPR) is a type of breathing protection device that uses a battery-powered fan to move ambient air through a filter or cartridge before delivering it to the user. This design provides an increased airflow, which can help in reducing the effort required to breathe compared to other types of masks that do not have mechanical assistance.

PAPRs are particularly beneficial in environments where chemical, biological, or radiological hazards are present, as they enhance the level of protection by maintaining a positive pressure within the respiratory space. This design helps to minimize the likelihood of contaminated air entering the mask, thus ensuring the wearer is protected.

On the other hand, a passive air-purifying respirator relies solely on the wearer’s inhalation to draw air through the filter and does not provide the same level of airflow or comfort. Other terms listed do not accurately describe this specific type of respirator, emphasizing the importance of recognizing the correct terminology and functionality of each equipment type.
