The companies who sell plug-in air fresheners advertise how they make your house smell clean and fresh, and show you photos that make it appear as if the fresheners are bringing nature right into your home. What the commercials don’t say is that plug-in air fresheners may also be bathing your house in toxic chemicals that can harm your health.
One of the primary concerns with plug-in air fresheners is their use of phthalates. In fact, the National Resources Defense Council conducted a study that concluded that 86% of the air fresheners tested contain phthalates. Why is this a problem? Phthalates are disruptive to the body, alter hormone levels, interfere with testosterone, and are associated with reproductive abnormalities and birth defects. They can also cause asthma and allergic reactions. And studies in animals show an alarming possibility of a link to cancer and liver and kidney toxicity.
But there is more. Air fresheners also typically contain formaldehyde, a toxic compound that is definitely linked to cancer of the nose and throat. Formaldehyde can also cause irritation of the throat and airways, potentially leading to infections and other respiratory ailments. In fact, a study in 2013 done by the International Journal of Public Health found that babies whose mothers used plug-in air fresheners during pregnancy were far more likely to have a serious lung infection than babies whose mothers did not.
