Through the process of photosynthesis, plants absorb light, carbon dioxide and water to manufacture sugar. The byproduct of this complex process of chemical reactions is oxygen. Even in buildings with the most advanced air filtration systems, none manufacture oxygen – the vital ingredient for healthy, breathable air.

Plants grown for interior landscaping are mostly comprised of species that are native to the understory of rainforests where there is less light and fewer breezes than in the canopy level. These plants naturally photosynthesize in lower light and have evolved to accelerate transpiration, a process that creates air movement. Transpiration circulates air and pulls airborne toxins into the leaves and roots.

In addition to oxygen, plants manufacture phytochemicals. These are natural chemicals that the plants use to protect themselves from microbes, insects and diseases. Phytochemicals suppress mold spores and bacteria in ambient air. Studies from NASA indicate that plant lled rooms contain 50 to 60 percent fewer airborne molds and bacterias than rooms without plants.
