ABSTRACT:
A device for sterilizing a air within a structure, the device having a housing structured to permit air to freely flow therethrough, a base structure coupled with the housing to maintain a bottom of the housing a distance above an underlying surface so as to not obstruct air flowing into the housing, and at least one ceramic heating bundle disposed within the housing. The ceramic heating bundle includes at least two elongate members formed of a ceramic material, disposed in abutting, tight clustered relation with one another, each containing a plurality of narrow, parallel passages structured to permit air to flow therethrough, and at least one heating wire disposed within at least one of the passages of at least one of the elongate members and structured to radiate heat through the ceramic material of the elongate members, thereby heating the air disposed within the passages until the air reaches a sufficient temperature to become sterilized and rise naturally and exit the passages due to convection, thereby creating a vacuum which draws a new supply of ambient air into the passages. The passages are sized and spaced relative to one another within each of the elongate members so as to maximize a ratio of a surface area of ceramic material exposed to the air flowing therethrough, per volume of ceramic material required to define the elongate member, and also to minimize a resistance to heat flow through the ceramic material defining the elongate member and therefore through the ceramic heating bundle.
