CES: New air filter mask sees solutions in high pollution and wildfire-prone countries Portland-based company Ao Air says its sleek, new "Atmos" mask could provide a more efficient solution for air filtration for countries facing wildfires, like Australia, because it eliminates the need for a seal. Introducing the product at the annual Consumer Electronics Show in Las Vegas, Ao Air says it will first target sales in South Korea, where air pollution is high but notes that they aim to provide better protection to the "hundreds of millions of very cool people living in really cool cities breathing really bad air".
