1. An air treatment system comprised of an air treatment media having at least a plurality of pairs of air flow passages formed therein and an infectious agent attenuator configured to attenuate or inactivate infectious agents in the air flowing through the air flow passages in the air treatment media, the infectious agent attenuator comprised of:
(a) a moisture-activated infectious agent attenuating or inactivating biocide, and
(b) a humectant comprised of sorbitol, the humectant capturing moisture from the air flowing through the air flow passages in the air treatment media, the captured moisture maintaining the attenuating or inactivating effectiveness of the infectious agent attenuator by maintaining moisture activation of the infectious agent attenuating or inactivating biocide.
