But looking at it purely from a technical standpoint but the Sharp and Coway and other actively monitoring filters are kicking into action because of an increased particle count in the air. Whereas the article is about NO2 gas emissions trapped indoors.
I am not sure these HEPA filters are fine enough to actually filter NO2, SO2, CO, etc, are they?
