3M Powerflow High Efficiency SP3 Particulate Filter

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.
