Fabric Softener Is the #1 Cause of Indoor Air Pollution — And That “Clean Laundry Smell” Could Be Harming Your Health

Limonene → Reacts with ozone to form formaldehyde (a known carcinogen)

Phthalates → Hormone disruptors linked to reproductive issues and developmental problems in children

And here’s the kicker:

So when you smell “fresh linen” or “ocean breeze,” you’re actually inhaling a mystery mix of toxins.

🔬 What Science Says

A landmark study by University of Washington researchers found:

Over 25 VOCs emitted from dryer vents using scented laundry products

7 hazardous air pollutants—including acetaldehyde and benzene (both carcinogens)

Levels of some chemicals exceeded federal safety standards
