Abstract
The present invention in an embodiment relates generally to an air purifier having an ultraviolet wave chamber which is accessible from the exterior designed for the placement of masks/respirators in need of decontamination. Such device preferably makes use of filters comprising copper foam.
Claims20
A combination air purifier and mask and respirator decontamination device comprising:
- (a) a housing having an inlet for receiving air, and an outlet for exhausting air, wherein the housing provides an air flow path for airflow between the inlet and outlet,
- (b) a fan disposed adjacent to the air inlet;
- (c) a chamber in the air flow path configured to permit multiple surgical masks and respirators to be placed in the chamber so each is separate from one another and having labelling associated with each mask and respirator, and having one or more ultraviolet light emitting sources in access therewith, said chamber having a sealable door allowing for access from outside the chamber, said door coupled to a kill switch to stop airflow between the inlet and outlet and turn off the ultraviolet light emitting sources when the door to the chamber is opened;
- (d) a first air flow filter downstream from said air inlet but before said ultraviolet light chamber;
- and
- (e) a second air flow filter upstream of said ultraviolet light chamber but downstream of said air outlet.

An air purifier comprising:
- (a) a housing having an inlet for receiving air, and an outlet for exhausting air, wherein the housing provides an air flow path for airflow between the inlet and outlet,
- (b) a fan disposed adjacent to the air inlet;
- (c) a first air flow filter downstream from said air inlet;
- and
- (d) a second air flow filter upstream of said first air flow filter but downstream of said air outlet;
- wherein at least the first or second filter comprises a copper foam containing filter.

The air purifier of claim:
- 7 further comprising:
- (e) a chamber having one or more ultraviolet light emitting source in access therewith between the first air flow filter and the second air flow filter.
A combination air purifier and PPE decontamination device:
- (a) a housing having an inlet for receiving air, and an outlet for exhausting air, wherein the housing provides an air flow path for airflow between the inlet and outlet,
- (b) a fan disposed adjacent to the air inlet;
- (c) one or more ultraviolet light emitting sources located in the air flow path;
- (d) a sealable door allowing for access into said housing an air flow path space proximal to said ultraviolet light emitting sources configured to permit multiple surgical masks and respirators to be placed therein such that each is separate from one another and having labelling associated with each mask and respirator, said sealable door coupled to a kill switch to kill the fan disposed adjacent to the air inlet and turn off the ultraviolet light emitting sources when the door is opened;
- (e) a first air flow filter downstream from said air inlet but before said ultraviolet light emitting sources;
- and
- (f) a second air flow filter upstream of said ultraviolet light emitting sources but downstream of said air outlet
- wherein at least the first or second filter comprises a copper foam filter.
