In 1989, NASA were studying ways to purify the air for astronauts living in space. They found some common houseplants provided a natural way of removing toxins like benzene & formaldehyde found in many everyday household products.
Working with a lead botanist from Oxford University and inspired by the ‘Energy Rating System’ for household appliances, we created the ‘Pollutant Absorption System’ for house plants. Complex NASA data was distilled into a simple, easy-to-understand key, to change the way consumers shopped for plants.
Instead of buying plants based on looks, they now bought plants based on their lifestyle.
