According to a recent research1, the effectiveness or removing indoor VOCs for different technologies applied invariety of air cleaners have been examined. The results showed that “… two properly designed in-duct UV-PCO devices effectively removed MOST of the tested compounds.” Furthermore, it pointed out that “While ionizers appear to be popular based on unit sales, tested products did not significantly remove thetest VOCs. In addition, a significant amount of ozone was generated and measured even though the units were operating quietly and using less power.” Therefore, this technology is not recommended by the authors.
Based on the above comparison, UV-PCO matching with a proper design is the most reliable technology in removing VOCs because of its outstandingperformance and few byproducts.
