The NASA Clean Air Study
Before we dive into our list of the best indoor air purifying plants, it’s important to understand the science behind their air-cleaning abilities. In the late 1980s, NASA conducted a groundbreaking study called the Clean Air Study, in collaboration with the Associated Landscape Contractors of America (ALCA).
The study, led by Dr. B.C. Wolverton, aimed to find ways to purify the air in sealed space stations. The researchers discovered that certain plants were remarkably effective at removing common indoor air pollutants such as benzene, formaldehyde, and trichloroethylene.
While the study was initially conducted with space exploration in mind, its findings have significant implications for improving indoor air quality in homes and offices on Earth. The plants identified in the NASA study are now widely recognized for their air-purifying properties and are often recommended for use in indoor spaces.
