Many people do not realise that they are not protected in their vehicles at all. On average, the air pollution inside your vehicle can be up to 2.5 times higher than the air outside. Exhaust emissions from cars, busses, trucks and off-road equipment produce dust, soot, particulate matter (PM10 and PM2.5) and harmful gases such as nitrogen dioxide and volatile organic compounds (VOCs). You could be passively smoking two cigarettes worth of nitrogen dioxide when sitting in traffic for just one hour because the air intake system of your car is typically right by the exhaust of the vehicles in front of you.
You can effectively clean the air inside your vehicle from harmful particles, micropollutants, allergens, cigarette smoke, odours and bacteria and stop breathing dangerous exhaust fumes and chemicals with the help of an in-car air purifier.
