Abstract: A method and system of remotely monitoring an operational status of electronic discharge devices in an air purification system senses emitted radiation at a location proximate the air purification system, alone or in combination with a determination of an amount of time remaining in an operational lifetime of the electronic discharge device, or an amount of power delivered to at least one of the electronic discharge devices. A determination of the operational status of at least one of the electronic discharge devices is made based on at least emitted radiation, and the status information is transmitted to a remote monitoring unit that receives the status information and displays an indicator of operational status. In one embodiment, the operational status of a UV-C germicidal lamp may be monitored using optically sensitive devices located within a purification system.

Abstract: A portable room air purifier includes a hollow cylindrical air filter disposed within a housing and having an inner surface circumscribing a cylindrical air treatment space and an outer surface. A sorbant material is disposed on the inner surface of the air filter and a germicidal lamp is disposed within the cylindrical air treatment space to emit germicidal light within the space and incident upon the sorbant material on the inner surface of the air filter. A fan is disposed in the housing to draw air from the cylindrical air treatment space through the air filter such that the air enters the filter through the inner surface and exits the filter through the outer surface. The portable room air purifier preferably includes an electrical circuit configured to power the fan and the germicidal lamp when the housing is in an assembled condition, and to deactivate both the fan and the lamp when the housing is disassembled.
