NASA Clean Air Study

The NASA Clean Air Study was a research project that was done in the 1990s to study the effects of plants on the air in our homes and offices. Scientists wanted to know if adding certain types of plants to a room could help improve the air quality by removing pollutants. So, they tested different plants in sealed chambers with different levels of air pollution inside. They found that many of the plants were capable of removing pollutants from the air and making it cleaner. This could help make our homes and offices healthier places to be!
