1. A disposable system for eliminating or reducing aerosol emitted from an enclosed heater/cooler unit including an enclosure, the enclosure containing a heater and defining an internal space of the heater/cooler unit, the system comprising:
a filter unit including a filter container and a filter element, the filter unit separate from and outside the enclosure of the enclosed heater/cooler unit, the filter unit configured to be fluidly coupled to the internal space of the heater/cooler unit and to a vacuum source;
a first tubing extending from the filter unit, the first tubing including a coupling for detachably coupling to the enclosure of the heater/cooler unit;
wherein the filter element includes a hydrophobic shutoff filter that stops vacuum flow when contacted by fluid; and
wherein, during at least a portion of the operation of the heater/cooler unit, the vacuum source is configured to create a negative air pressure in the filter container, such that any aerosol in the internal space of the heater/cooler unit is suctioned into the filter container and filtered by the filter element.
