How to grow fresh air | Kamal Meattle
TED

Researcher Kamal Meattle describes how an arrangement of three common houseplants placed in specific spots can measurably clean the air in a home or office. It is a short TED talk based on his work in a plant-filled building.
HN commenters cite it in threads about indoor air quality, CO2 and houseplants as a cheap, low-tech approach.
