The Research

O2ganic’s services are based on research first explored in 1989 by National Aeronautics and Space Administration (NASA) that investigates the air filtering capabilities of certain indoor plants.

The first study, commissioned by NASA and the Associated Landscape Contractors of America found that certain common indoor house plants significantly reduce the amount of noxious chemicals found in cleaning products, furniture, and central heating and cooling systems, such as formaldehyde, xylene and ammonia, received wide attention and spurred a volume of research into the benefits of indoor plants.

Since then, additional study has revealed the effectiveness of common indoor plants to also filter particulate matter (PM), a mixture of airborne solid and liquid particles that can be small enough to penetrate and damage the lungs. Such plants have also been found to increase humidity levels indoors, as well as employee comfort and productivity in an office environment.

Below is a list of publications detailing the findings of a compelling group of studies. For a comprehensive, readable overview of the findings, O2ganic recommends picking up a copy of How To Grow Fresh Air.
