House committee substitute to the 1st edition makes the following changes. 

Amends proposed GS 131E-78.4 by replacing the term smoke evacuation system with smoke evacuation/filtering system, now defined as stand-alone, portable equipment that effectively captures, filters, and eliminates surgical smoke at the site of origin before the smoke makes contact with the eyes or respiratory tracts of occupants in the room. Specifies that this equipment does not have to be interconnected to the hospital or ambulatory surgical ventilation or medical gas system.
