Powered Air Purifying Respirators (PAPR) are motorized systems powered by a battery pack which draw air through a filter or cartridge to provide respiratory protection to the wearer. The blower unit can be mounted on the waist, face, or head, depending on the system selected. Potential benefits include:
Certain PAPR systems provide a higher level of respiratory protection than non-powered air filtering respirators.
Constant flow of air can provide cooling for the worker, resulting in greater comfort for the wearer
Loose-fitting headgear options provide respiratory protection without the need for a tight faceseal or fit testing
Battery-powered blower pulls the air through the filter resulting in no additional breathing resistance to the wearer
