Filter Can Remove Toxic Air Pollution From Inside Your Car

Researchers in Copenhagen have created a market-ready anti-pollution filter designed to quickly remove nitrogen dioxide (NO2) and particulate matter from inside vehicles. They say the Airbubbl is the first technology shown to effectively remove nitrogen dioxide and other traffic pollution from inside cars. A prototype of the device was independently tested in London inside the 'Smogmobile' - a mobile pollution detection vehicle laboratory made by UK firm Enviro Technology. It drove around London measuring pollution levels with the Airbubbl both switched on and off. Within ten minutes of switching on Airbubbl, NO2 concentrations inside the car fell by 95 percent. The device is lightweight and attachable to the back of car headrests. Its makers say driving for two hours per day in a polluted area would require changing the filter once a year. A Kickstarter campaign has raised £50,000 (67,500 USD) and ends on December 8.
