Abstract
Previous evaluation of a commercially available charged electrode—filter system, carried out as part of a more general study of environmental control in hospital clean rooms, questioned the effectiveness of the system for odor removal. The current study was undertaken in an effort to carefully evaluate the effectiveness of this charged electrode system (consisting of high-voltage and high-frequency units) for odor “removal” or “neutralization” in a hospital clean room. Tests were conducted “in situ” at three different odorant (sulfide) concentration levels with judges preselected from hospital personnel. Both dependent and independent statistical treatments were given to the data obtained. The results indicate that the odorant control system studied was unable to demonstrate reduced or “neutralized” odor effect.
