Researcher Kamal Meattle has a vision to reshape commercial building in India using principles of green architecture and sustainable upkeep (including an air-cleaning system that involves massive banks of plants). He shows how an arrangement of three common houseplants, used in specific spots in a home or office building, can result in measurably cleaner indoor air.
He has spent a great deal of time in India and abroad convincing corporate leaders, diplomats, energy ministers, and other government officials that his ideas about sustainability, individual responsibility, and respect for the environment can ensure a healthier future for everyone. ‘Either you are overwhelmed by the fact that there are so many problems and so many people,’ says Meattle, ‘‘or you find solutions to help in any way you can.‘.
I’m not sure specifically how effective one plant is over another, it may be that any plant helps just as much as the next. Any excuse if any to keep houseplants around the time. Things like window boxes with flowers could also be effective in apartment style builds etc.
