New research has shown that scented wax melts and other products release as much indoor pollution as a diesel engine.

A new study reveals that people may be exposed to unhealthy levels of airborne pollutants inside their homes, even if the outdoor air quality is good.

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.

Bringing aromas indoors with the help of chemical products -- yes, air fresheners, wax melts, floor cleaners, deodorants and others -- rapidly fills the air with nanoscale particles that are small enough to get deep into your lungs,
