According to a report released by the US Natural Resources Defense Council, many of the air fresheners used in our homes on a regular basis contain compounds that can cause us harm and even cancer. The vast majority of air fresheners, even those labeled "natural", contain a group of chemicals called phthalates, the most common being DEHP, DIDP and DINP. As part of the National Toxicology Program in the United States, it was reported that DEHP is a substance that may be carcinogenic to humans and that these chemicals may adversely affect brain development and sexual development. It’s important to note that the most at risk are infants, pregnant women, and chronic patients.
In our home we either aerate the house or typically use pure essentials oils to freshen the air.
