I'm very skeptical that these plants can significantly change the indoor environment, unless you turn your house into a greenhouse. Does anyone have a source pointing to the contrary?
"Recently, Waring and his colleagues reanalyzed all 195 studies that have examined whether houseplants can filter the air. They found that some types of plants can remove higher amounts of VOCs than others. But once you factor in the effects of working in a large room, none of the plants are able to do much."
