This NIOSH-approved SP3 particulate filter helps provide high efficiency respiratory protection in environments containing particulates. Filter should be used with 3M™ Powerflow™ Powered Air Purifying Respirator (PAPR) systems.

NIOS H-approved SP3 particulate filter used for 3M™ Powerflow™ systems from 3M for high efficiency respiratory protection against particulates. 

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
