Air conditioning reduces in-car pollution by 34%

While sitting in your car during the daily commute may seem fairly harmless, drivers are exposed to huge amounts of air pollution while in their vehicle. But scientists believe they may have found a simple way to reduce this in-car pollution. In a new study, researchers discovered that using air conditioning can reduce the amount of pollutants in the car by up to 34 per cent. The researchers used portable instruments and sensors to monitor and measure the pollutant levels of a car's indoor cabin air and the air directly outside the car during their own daily commutes. The cars were fitted with dashcams, allowing the researchers to identify a given pollutant concentration each time they were stuck behind a bus or truck, in traffic on a freeway, stopped at a red light, or driving past restaurants or construction sites.
