Scientists at Stanford University have developed a ridiculously effective yet impressively inexpensive pollution air filter. This semitransparent filter is capable of filtering out 99% of what are known as 'PM2.5 particles', which are considered to be the particles most harmful to the human respiratory tract.

These filters could be used to create better protective facemasks, window screens and industrial filtration systems and could even help reduce pollution from cars and smoke stacks. Incredibly, these air filters don't require any power to function making them energy-efficient as well.

With pollution a huge problem worldwide but particularly in booming developing markets like China and India, this inexpensive pollution air filter solution could prove to be a huge boon.
