“Air Bubbles” are made of 99% air, water, and air-purifying chlorella culture. This new biodigital project demonstrates how advanced integration of biotechnology with the built environment can give rise to a growing generation of “living buildings” that combine aesthetic appeal with efficient ecological performance.

The project encourages visitors (especially children) to interact directly with the structure and experience the air-purifying effect of microalgae cultures, while immersing themselves in “bubbles” that are constantly producing fresh oxygen. The organic structure presents a playful and soft feeling, like a giant Q-bomb jellyfish, with its transparent skin intuitively expressing the biotechnology it contains.

The open-air membrane structure is monitored in real time through an array of sensors that sense wind and cause vibrations in the inflatable structure. Sensitive arrays of culture lights will be activated by these sensors, which in turn support the algae’s photosynthesis and improve its air-purifying capabilities. The whole organism triggers a new symbiotic relationship: the more people play in it, the cleaner the air becomes.

The filtering effect is further enhanced by the architectural form of the structure. The TPU membrane used in the structure controls the microclimate inside the bubble. Doors constructed from inflatable membranes stimulate air recirculation and natural ventilation.

The “Air Bubble” air purification eco-machine combines lightweight inflatable technology with 24 photobioreactors (12 on each side). The continuous circulation flow is able to absorb six core pollutants, including fine particulate matter PM2.5 and PM10, ground-level ozone, carbon dioxide, sulfur dioxide and carbon monoxide. The entire project is able to absorb 97% of nitrogen and 75% of particulate matter in the air.
