1. A portable air treatment system configured to be carried by an individual, comprising:
an air inlet configured to receive atmospheric air;
a first enclosure in fluid communication with the air inlet;
an air compressor positioned within the first enclosure and configured to compress the atmospheric air passing into the first enclosure via the air inlet, wherein the air compressor is configured to compress the atmospheric air to a minimum pressure of three times atmospheric pressure at an air inflow rate of at least 2 liters/min, thereby increasing a temperature of the atmospheric air to a minimum temperature of 100° C.;
an air chamber in fluid communication with the first enclosure, wherein a pressure of the air chamber is maintained at a minimum pressure of at least three atmospheres and a temperature of the air chamber is maintained at a minimum temperature of 170° C. over a plurality of cycles of treated air;
a second enclosure in fluid communication with the air chamber; and
an air decompressor positioned within the second enclosure and configured to decompress the compressed atmospheric air passing out of the air chamber, wherein the air decompressor comprises a decompression cylinder and a decompression piston adapted to move in an upward stroke and a downward stroke, and wherein the air decompressor is configured to expand the compressed atmospheric air to approximately atmospheric pressure, thereby decreasing the temperature of the compressed atmospheric air to a temperature less than 50° C.
