Today, researchers are unveiling a new air filter technology that uses a surprising material - pig snouts! Scientists at the University of Cambridge have discovered that pig snouts can be used as a filter to remove toxic chemicals from the air we breathe. The research team found that pig snouts are highly absorbent and can trap and neutralize potentially harmful airborne pollutants such as nitrogen dioxide and ozone. Tests showed that the pig snouts were able to reduce the levels of these pollutants by up to 90%. This new technology could be used to create more efficient and eco-friendly air filters for our homes and workplaces.
