I purchased two of these and they were advertised to remove VOC’s which was the specific reason I purchased them. After finding thorough a device that they do not remove VOC’s I see that this has been removed from the description. Unfortunately I have two now that do not do what they claim to do so they are useless to me and apparently I wasted my money. Very disappointed with this. They should do as they were advertised to do. I have been running them daily for the past 3 months only to learn that they are doing nothing.
