An innovative, citywide solution to air pollution
Our air quality is at all-time low – an unfortunate consequence of urban pollution. But we have the solution: “City Air Purification System” (CAPS), an innovative, state-of-the-art invention jointly developed with Arup, protecting those in populous cities by improving air quality through novel filtration and sanitisation technologies. The revolutionary device doubles as a functional bus shelter, with an innovative air purification system that uses dual metal cone-shaped columns to deliver sanitised air into its semi-enclosed space.

Current Issues

Targeting essential environmental issues,
highlighted by the World Health Organization
Targeting essential environmental issues,
highlighted by the World Health Organization

Air pollution

WHO ranks air pollution as the single largest environmental health risk in the world.

Pandemic virus

Smaller particles eventually lead to the bloodstream, leaving the body at target to novel pandemic viruses.

Lung damage

Air pollution causes lung damage, with small particles penetrating deeply leading to respiratory diseases.

Features

CAPS’ patented technology efficiently recycles and delivers clean air within a covered, semi-open space.

Solar panel on roof
CAPS harvests solar energy through its roof-installed 19.5% extra-high efficiency photovoltaic panels, ensuring consumption is self-sustaining while simultaneously saving energy.
Air curtain
CAPS’ innovative ‘The Invisible Shield’ technology shields pollutants through its air curtain and dual air currents, while minimizing indoor cool-air leakage.
Air purification & sanitization system — Plascide Air Sanitizer
CAPS’ Plascide Air Sanitizer is a locally invented, award-winning technology that offers protection from cross-infection and harmful VoCs. Its high energy micro-lightning technology eliminates coronaviruses, ensuring sanitized air flows freely within the bus shelter.
Air purification & sanitization system — Multi-HEPA filters
CAPS’ Multi-Hepa Filter, developed by the Nano and Advanced Materials Institute, efficiently removes fine suspended particles (PM10 and PM2.5) in the air. By utilizing an anti-bacteria, nano-porous filtration system, volatile organic compounds are decomposes and microbes eliminated.
IoT sensors for real-time air quality data

Hidden air purification vents in the metal column
Sanitised air is delivered to those under the canopy through the vents in the metal cone-shaped columns.

Energy Efficient

Solar-powered energy that
is self-sustaining
CAPS harvests solar energy through its roof-installed 19.5% extra-high efficiency photovoltaic panels. Energy-saving aerofoil electronically commutated (EC) plug fans also ensure power is self-sustaining while consumption is kept to a minimum.

Smart Control

Connected to the cloud
for customized data
Embracing cloud technology, CAPS connects through IoT and mobile internet access for real-time monitoring, data comparison and interactive displays. Useful daily information on weather, air quality, bus schedules and other live data is also easily customized.

Applications

Citywide protection for all
Alongside its current application, CAPS has multiple functions that contribute to our everyday wellbeing. The technology is easily adapted to built-environments, from canopy structures to street vendors and roadside restaurants. It also has massive potential in densely populated areas, thriving in cities such as Hong Kong with established public transport networks – CAPS can be used at all forms of bus stops, as well a tram stations and taxi stands.
Breathe in purified air while en-route to your next destination – whether it’s the work grind, a trip to a friend’s place or dinner out on the town – enabling practicality and versatility. CAPS can easily be adapted to most Asian metropolises and developing markets, tackling not only air pollution, but contributing greatly to sustainable urban growth.
