Odorox effectively removes all traces of VOC’s which can appear in many different forms (gases, liquid etc.). The hydroxyls literally attack each individual molecule that has been created by the source that usually shows up in a gas form whether it is in a new home, gas plant, sewage plant or any other work place. The exhausted air from the unit not only supplies the hydroxyls to clean the ambient air but will be VOC free itself, even though it is drawing in VOC contaminated air.
