The air purifying billboard is the pinnacle of creativity and innovation, and shows
some very clever use of advertising in public spaces.
Designed by the University of Engineering and Technology in Lima, Peru, this
advertising billboard, at first glance, aims to inspire young engineers to join the
university’s cutting edge programmes.
Importantly, however, this billboard is made of a specially developed material that
scrubs air clean of contaminated particles and purifies it. A single billboard doing
the job of approximately 1200 trees, this ingenious design works by combining
polluted air with water, using basic thermodynamic principles to actively dissolve
pollutants in water to release fresh air. The billboard can purify up to 100,000 cubic
meters of air every day, vastly improving air quality in urban areas. Currently
installed in Lima, we hope this bright idea soon makes its way into city centres the
