Claim 0:
1. A two-way protective respirator system for removing harmful airborne contaminant particles and vapor components from ambient air breathed by a person wearing the respirator and biologic virus, bacteria, and other pathogen particles from air exhaled by the person from the respirator and emitted to persons within a group setting within the surrounding community, the two-way protective respirator system configured to communicate with a source of ambient air comprising:
a respirator worn over the nose and mouth of the person and defining a first chamber, the respirator fitting closely to the face of the person to reduce leakage of ambient air into or out of the first chamber between the person's face and the respirator, the respirator having an inlet orifice and an outlet orifice;
a blower fan for drawing the ambient air into a hose connected to the inlet orifice of the respirator to produce a first airflow stream under a positive pressure condition for delivery to the first chamber of the respirator;
a filter unit operatively connected to the blower fan for removing harmful airborne contaminant particles or vapor components contained within the ambient air from the first airflow stream before it is delivered to the first chamber of the respirator;
a gaiter made from woven fabric extending from the respirator and having lateral edges that lie against the chest of the person, a second chamber defined by the gaiter fabric and the person's chest;
wherein the filter unit removes harmful airborne contaminant particles or vapor components contained within the ambient air that is delivered as the first airflow stream to the first chamber to protect the person breathing in the first airflow stream contained in the first chamber; and
wherein an exhaled second airflow stream emitted by the person into the first chamber flows out through the outlet orifice of the respirator into the second chamber defined by the gaiter and the person's chest, submicron biologic virus, bacteria, and other pathogen particles contained within the exhaled second airflow stream clinging to neighboring fibers of the woven fabric of the gaiter to remove them by a diffusion separation mechanism before the resulting sanitized exhaled airflow stream exiting the gaiter enters the surrounding community to protect persons within the group setting from exposure to the virus, bacteria, and other pathogen contaminant particles.
