Although well-established technologies can remove certain toxins from indoor environments, methods capable of eliminating all of them do not yet exist. Biological methods, however, which are based on plants and their associated microorganisms, could hold significant promise. To achieve high toxic remediation, utilization of the soil microorganisms in the root zone of the plant is vital. Moreover, evidence suggests that in addition to cleaning the air, plants in indoor environments offer psychological, physiological and cognitive benefits. This paper provides an overview of the effects of plants on indoor air quality on the broader benefits of incorporating vegetation into indoor environments.
