Air pollution is an undisputed problem in the U.S. and the World Health Organization estimates 2.4 million people die annually world wide of causes attributable to air pollution. In one year, 2,000 square feet of the SMOG-EATING Tile mitigates the same amount of nitrogen oxide (a major component of smog) produced by one car driving up to 10,800 miles, making BoralPure™ SMOG-EATING Tile an important solution to smog and the health problems it causes. The BoralPure™ SMOG-EATING Technology works via a catalyst embedded in the upper portion of the roof tile. When exposed to sunlight it speeds up oxidization reducing nitrogen oxide, which can be generated from fossil fuel burning processes resulting from operation of motor vehicles. Working much like a catalytic converter does in a car; SMOG-EATING Tile transforms harmful substances into safe ones, protecting the quality of the air we breathe.
