“Hy-Phy” Indoor Bio Ventilation

Project Information

“Hy-Phy” plants act as a purifier for indoor spaces, where people spend more than 90% of their time. In these indoor spaces, building occupants are likely to have the greatest contact with various pollutants, placing them at risk of infection, diminished cognitive function, productivity and well-being. The  “Hy-Phy” concept incorporates a high density of hydroponic Azolla plants inside an airtight chamber with mechanical air movement across the roots to reach maximum removal efficiencies.

HyPhy is a personal clean air pod where a micro-fern called Azolla is integrated into systems furniture to provide personalized air circulation and purification.  The HyPhy modules contribute to pathogen decay through modifying air movement indoors, adding humidity, treating the air with UV lights, and natural bioremediation. We call this personalized approach, “virtual ventilation,” since indoor air is improved without adding additional outside air and based on our preliminary findings and existing literature, we estimate that HyPhy air purifying pods can contribute to ~400 ppm reduction on indoor CO₂ concentration which could result in a ~30 % increase in occupants’ cognitive function and decision-making performance.  HyPhy personal air pods decrease risk of spreading pathogens indoors and provides localized fresh air to support human health and performance.
