Portable room air purifier
First Claim
1. A portable room air purifier comprising:
- a housing;
a hollow cylindrical air filter disposed within said housing, said air filter having an inner surface circumscribing a cylindrical air treatment space and an outer surface, and wherein a sorbant material is disposed on said inner surface of said air filter;
a germicidal lamp disposed within said cylindrical air treatment space to emit germicidal light within said space and incident upon said sorbant material on said inner surface of said air filter; and
a fan disposed in said housing to draw air from said cylindrical air treatment space through said air filter such that the air enters the filter through the inner surface and exits the filter through the outer surface.

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.

26. A method of purifying air in a room, said method comprising:
-
positioning a portable room air purifier in a room; drawing air from the room into a first air treatment zone bounded on at least one side by an air filter and containing a germicidal lamp; treating the air in the first air treatment zone by exposing the air to germicidal radiation emitted by the germicidal lamp; drawing air from the first air treatment zone into a second air treatment zone in the air filter containing activated carbon; drawing air from the second air treatment zone through a third air treatment zone in the air filter configured to remove particulates; and expelling the treated air from the room air purifier. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
