“Sick building syndrome” caused by poor indoor air quality has been linked to illness and lack of productivity around the world.

One easy way to fight it is to decorate with pot plants. Not only do they help in purifying the air of all the toxins we put into it with our cleaning chemicals and household products, they are also credited with many other benefits such as lower stress levels and increased happiness and productivity.

And who better to find the best plants for the job than NASA, with its focus on the well-being of astronauts in space?

Wikipedia’s “NASA Clean Air Study” article has a chart detailing which air-filtering plants are most effective at removing horror pollutants like benzene, formaldehyde, trichloroethylene, xylene, toluene and ammonia. Pay attention to the last column “toxic to dogs, cats” and in particular watch out if babies or children might be able to reach any of them.
