Ameriški raziskovalci so preizkušali, katere sobne rastline najbolj učinkovito odstranjujejo hlapne organske spojine iz zraka. Barve, pohištvo, kopirni stroji, tiskalniki, obleke iz kemične čistilnice, kozmetika in čistila so pogosto viri acetona, benzena, formaldehida in podobnih lahko hlapljivih substanc, ki lahko povzročajo zdravstvene težave. Kot najbolj učinkovite so se izkazale Zmajevke (Dracaena), Bromelijevke (Bromeliaceae) in Čopasta zelenčica (Chlorophytum comosum).

In 12 hours, an unassuming bromeliad (a tropical plant with long, swordlike leaves and spiky red flowers) removed at least 80 percent of six different compounds from the air inside a 76-liter container (roughly the size of a sedan’s gas tank). A dracaena, with its long, strap-like leaves, was exceptionally good at gobbling up acetone — it removed 94 percent of the gas from the air. Spider plants were lightning fast — the minute one was placed inside the container, the concentration of VOCs immediately began to go down.
