In London over 2 million people live in areas which exceed air pollution limits, causing thousands of premature deaths every year. The cost to the NHS is £3.7 billion annually.
Velo2 bicycle tyres harness human power to clean the polluted air.
Using two solid halves with diagonal perforations, air passes through the tyres.
A cleanable, biodegradable HEPA filter combined with an activated carbon filter removes polluting particles.
The product is proposed for hire bicycles. If Velo2 were installed on all Santander Cycles, 105 tonnes of pollutants would be filtered across London each year.
