The system can be used in buildings and in aircraft and can be adapted for use with the gasper outlets presently employed on aircraft. A method for providing fresh exterior air to the enclosed area and the user includes conducting the air to an outlet for the exterior air which is located within the area, conducting the exterior air from the outlet to at least one breathing cavity of the user, and preventing the user from inhaling ambient atmosphere from within the enclosed area.
