Scented products cause indoor air pollution on par with car exhaust
Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.
New research by Purdue University, the latest in a series of Purdue-led studies, examined how scented products – in this case, flame-free candles – are a significant source of nanosized particles small enough to get deep into your lungs, posing a potential risk to respiratory health “To understand how airborne particles form indoors, you need to measure the smallest nanoparticles – down to a single nanometer,” said Brandon Boor, associate professor in civil engineering at Purdue and the study’s other corresponding author. “Our research shows that fragranced products are not just passive sources of pleasant scents – they actively alter indoor air chemistry, leading to the formation of nanoparticles at concentrations that could have significant health implications,” said Jung.
