Portable ionization unit for attachment to an overhead airflow nozzle

A portable ionization unit for attachment to an overhead airflow nozzle, the portable ionization unit comprising:

• a tubular housing with an attachment device configured to be user-attachable and detachable from the overhead airflow nozzle, wherein the tubular housing includes an air inlet at a first end configured to receive air from the overhead airflow nozzle, and an axially aligned air outlet at an opposing second end via which the air exits the tubular housing, the attachment device including at least one spring-loaded grabber which is rotatably hinged proximately to the first end of the tubular housing and configured to apply a grabbing force to the overhead airflow nozzle in a direction towards a central axis of the tubular housing;
• and
• an ionizer mounted within the tubular housing, the ionizer comprising:
• a bipolar ionization emitter and associated circuitry,
• a rechargeable battery to provide power for the bipolar ionization emitter and associated circuitry,
• a power switch for turning the ionizer on and off,
• a USB charging port with a receptacle for charging the rechargeable battery, wherein the USB charging port is mounted so that the receptacle is user-accessible from outside the tubular housing;
• and
• an LED light that is illuminated when the ionizer is turned on;
• wherein the ionizer is configured to ionize the air which passes through the tubular housing via the air inlet and the air outlet.
