Architect Dan Roosegaarde and nanoparticles expert Bob Ursem created a smog filter that uses ion technology to ingest dirty air, filter it, and return clean air through vents. The filter is installed in a 7meter high steel tower that can be easily shipped. Initially installed in Rotterdam, expansion plans include Beijing, whose pollution inspired the product’s design. The filter has the capacity to clean 30,000 cubic meters of air in an hour. The air space roughly the size of a football stadium could be filtered in 1.5 days. The tower is also energy efficient running on 14,000 kilowatts of power. In Rotterdam, it is powered by wind and will potentially be powered by solar in other cities.
Air pollution causes nearly 3 million deaths per year and is expected to get worse, especially in developing countries, if steps to resolve are not addressed. The filtering towers will not solve the problem completely, but it is a good concept to increase awareness of air quality conditions and encourage wider air pollution reduction measures.
- Governments in cities/countries with poor air quality
- Citizens in cities/countries with poor air quality
- Architects/Urban Planners
- Initial funds were raised on Kickstarter
- Plan is to implement in public parks in Beijing with leasing options available to keep costs down
- Potential expansion to other countries that face air quality concerns such as India
- Public-Private Partnerships would be key in implementing on larger scale and to help cities with the costs
