More than 3.8 million deaths worldwide each year are blamed on household air pollution, and scientists are turning to many strategies to try to clean the air in homes and business, including the use of everyday plants.
A Purdue University project called the Biowall is showing promise at using a wall of plants to clear the air within businesses and homes.
Biowall - Air - Filtration - System - Buildings
"The Biowall is an eco-friendly air filtration system that can be used in residential buildings to improve air quality," said Bill Hutzel, a professor of mechanical engineering technology in Purdue's Polytechnic Institute, who leads the research team. "We combine Purdue expertise in building design, engineering and agriculture to help with the home of the future."
This system uses plants grown in a loosely packed growth media, allowing air to pass through the media. The plant's roots absorb volatile organic compounds from the passing air, removing these compounds from circulation. The system is integrated into the return duct...
