What if the air freshener in your car was more dangerous than the pollution outside?

In this explosive episode, Darin reveals what’s really inside those “harmless” little trees hanging from car mirrors—and why they could be silently damaging your health. Backed by real science and peer-reviewed studies, Darin uncovers the shocking truth about volatile organic compounds (VOCs), the health effects on the brain and lungs, and the corporations that won’t label them. You’ll also learn how to detox your air, reclaim your health, and even start a grassroots movement to get a fragrance-free option in ride shares like Uber and Lyft.

Studies:

1. There’s this study called “Volatile Chemical Emissions from Car Air Fresheners”—and wow. Researchers analyzed 12 popular car fresheners—those trees, clips, sprays, gels—you name it. Here’s what they found: 546 volatile organic compounds. That’s VOCs. Out of those, 30 were considered potentially hazardous—things like formaldehyde, benzene, and other stuff you definitely don’t want marinating your brain. And you know what’s wild?
Not a single one of those hazardous chemicals was listed on the label.
(Steinemann et al., 2020)
2. There’s a study called “Fragranced Consumer Products: Effects on Asthmatics”—and it found that over 64% of people with asthma reported real symptoms from these scented products: wheezing, headaches, even full-on asthma attacks. And 41% said air fresheners were the trigger (Steinemann, 2017).
3. Another one? “Migraine Headaches and Fragranced Consumer Products.” Nearly half of the people who get migraines said air fresheners specifically set them off (Steinemann & Nematollahi, 2020).
4. And if you’re neurodivergent—like folks with autism? This next one breaks my heart.
In the study “Fragranced Consumer Products: Effects on Autistic Adults,” 83.7% of autistic individuals said fragranced products triggered serious neurological and respiratory problems—and 63% said air fresheners were one of the worst offenders (Steinemann, 2018).
5. In a study out of Nigeria, researchers exposed mice to a solid commercial air freshener. After a few weeks, the mice showed increased anxiety, depression-like behavior, memory loss, and signs of oxidative stress in the brain. Their brains were literally under chemical assault.
The study’s called “Neurobehavioral Effects of Prolonged Exposure to Solid Air Freshener in Mice.” Check it out—it’s eye-opening (Umukoro et al., 2019).
6. Sorry to tell you… greenwashed products aren’t any better. In the same 2020 study I mentioned earlier, researchers tested “natural” versions too—and found no meaningful difference in the chemicals they released (Steinemann et al., 2020).
