The present invention provides a portable protective system for protecting a wearer, and for protecting the environment about the wearer. The protective system includes a face shield coupled with a head cradle for supporting the face shield on the wearer's head. The face shield and a wearer's face substantially define a breathing zone charged by a battery-powered blower carried on the head cradle. An bag-like inlet filter element encompasses the blower to provided filtered air to the breathing zone, and an outlet filter element is operably associated with the face shield.
