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
