Room air decontamination device

Air decontamination apparatus comprising:

• a cabinet having an inlet for contaminated air and an outlet for cleaned air;
• a duct assembly inside the cabinet and having an air inlet associated with the cabinet inlet and having an outlet associated with the cabinet outlet for cleaned air;
• a blower in the duct assembly and arranged to move air from the inlets, through the duct assembly and out through the outlets;
• a first filter in the duct assembly upstream from the blower;
• a germicidal light generator in the duct assembly downstream from the blower;
• a final filter in the duct assembly and arranged to filter all of the air passing through the duct assembly to the outlets;
• a bag associated with at least one of the filters to facilitate removal of the filter from the duct assembly without exposure of the filter to the environment outside the duct assembly;
• and
• a bag associated with the light assembly to facilitate removal of the light assembly from the duct assembly without exposure of the light assembly to the environment outside the duct assembly.

Air decontamination apparatus comprising:

• a duct assembly having an air inlet for air to be decontaminated and having an air outlet for decontaminated air;
• a blower in the duct assembly and arranged to move air from the inlet, in a path through the duct assembly and out through the outlet;
• a filter in the flow path;
• a bag associated with the filter to facilitate removal of the filter from the duct assembly without exposure of the filter to the environment outside the duct assembly;
• a wall opening in the duct assembly adjacent the filter;
• a flange around the wall opening;
• and
• a closure on the flange;
• the bag associated with the filter having an end secured around the flange whereby the closure can be removed from the end of the flange inside the bag, and then the filter can be removed from the duct assembly into the bag, and then the closure can be reinstalled on the flange without air communication between the interior of the duct assembly and the environment outside the duct assembly at the wall opening.

Air decontamination apparatus comprising:

• a duct assembly having an air inlet for air to be decontaminated and having an air outlet for decontaminated air;
• a blower arranged to move air from the inlet, in a path through the duct assembly and out through the outlet;
• an air treatment device in the flow path;
• a bag associated with the device to facilitate removal of the device from the duct assembly without exposure of the device to the environment outside the duct assembly;
• a wall opening in the duct assembly adjacent the device;
• a bag mount and sealing surface around the opening;
• a closure inside the bag and closing the opening;
• the bag having an end secured around the sealing surface whereby the device can be removed from the duct assembly into the bag, without air communication between the interior of the duct assembly and the environment outside the duct assembly at the wall opening.
