Sino Group (the 'Group') and Hong Kong Innovation Foundation ('HKIF') unveiled the City Air Purification System 2.0 ('CAPS 2.0'). The invention, jointly developed by Sino Inno Lab and Arup, doubles as a functional bus shelter and aims to protect those in populous cities by improving the surrounding air quality. The full-scale CAPS 2.0 bus shelter will be on display at Central and Western District Promenade (Central Section) from 1 April to 6 June 2021 for the public to have a first-hand experience of the novel filtration and sanitisation technologies of this innovative air purification system. The CAPS 2.0 can serve as a citywide solution to urban pollution: its patented technology efficiently recycles clean air within a semi-open space and has been proven to reduce pollution exposure by half, remove 99.95% of PM0.1 airborne allergens, and kill viruses, bacteria and fungi within seconds. The CAPS 2.0 draws in surrounding polluted air, creating an invisible shield-like air curtain from the underside of the canopy, while concurrently generating air currents within that space to clean up the air. Polluted air is then internally purified with its dual protection technology, which removes harmful suspended particles and eliminates coronaviruses. The patented CAPS 2.0 is a second-generation prototype of the system first introduced in 2015, and has been awarded the Gold Medal and the Industrial Design Prize at the 47th International Exhibition of Inventions Geneva in 2019 as well as Gold Medal with Jury Commendation at the Silicon Valley International Invention Festival 2019. Alongside its current application, CAPS 2.0 has multiple functions that can contribute to everyday well-being. The technology can be easily adapted to a variety of built environments, with the potential to be adapted for use in densely populated areas of most Asian metropolises with established public transport networks. From 1 April through until 6 June, visitors will be able to find out more about this award-winning technology, fully innovated and designed in Hong Kong, through the educational showcase. The CAPS 2.0 bus shelter will then travel on to Olympian City with students from a local university enlisted to monitor and analyse the data collected from the roving exhibition for further educational purposes.
