The 3M™ Powerflow™ High Efficiency (HE) SP3 Particulate Filter is a NIOSH-approved SP3 particulate filter that helps provide high efficiency respiratory protection in environments containing particulates. Filter should be used with 3M™ Powerflow™ Powered Air Purifying Respirator (PAPR) systems.
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.
