That little tree dangling from your rearview mirror might be doing more than masking unpleasant odors. Recent research reveals car air fresheners contain numerous potentially harmful chemicals that could be affecting your health during daily commutes. Before reaching for that pine-scented freshener, here's what science says about these common products.
What's Actually in Your Car Air Freshener?
Many car air fresheners typically contain a mixture of:
-
Volatile Organic Compounds (VOCs) - Synthetic chemicals that easily become vapors at room temperature
-
Phthalates - Chemical plasticizers that help fragrances last longer
-
Formaldehyde - A known carcinogen that can form when air freshener chemicals react with air
-
Benzene, toluene, and xylene - Industrial solvents with known health risks
-
Synthetic fragrances - Proprietary blends protected as "trade secrets"
According to studies, a single air freshener can release over 100 different chemicals into your vehicle's confined space. More concerning, researchers found that 99% of these chemicals never appear on product labels.
Health Risks You Should Know About
Exposure to air freshener chemicals has been linked to numerous health concerns:
Respiratory System Impacts
-
Asthma attacks and exacerbation
-
Breathing difficulties
-
Throat irritation
-
Coughing and wheezing
-
Bronchitis
Neurological Effects

The Poison Control Center reports that accidental exposure (particularly for children who might ingest liquid air fresheners) can cause serious toxicity ranging from minor irritation to life-threatening effects.
Understanding Exposure in Vehicle Environments
Your car creates a particularly problematic environment for air freshener use:
-
Limited ventilation - Even with windows cracked, chemicals concentrate in the small space
-
Extreme temperature fluctuations - Heat accelerates chemical reactions and emissions
-
Extended exposure - The average American spends over 290 hours per year in their vehicle
-
Secondary pollution - Freshener chemicals react with existing pollutants from traffic
Safer Alternatives for Your Vehicle
You don't have to settle for unpleasant odors or dangerous chemicals. Consider these healthier options:
Natural Odor Absorbers
-
Activated charcoal bags placed under seats absorb odors without adding chemicals
-
Baking soda containers naturally neutralize unwanted smells
-
Moso bamboo charcoal pouches effectively remove odors and excess moisture
-
Cotton sachets filled with whole coffee beans
-
Cinnamon sticks wrapped with a natural fiber ribbon
-
Dried citrus peels (replace regularly to prevent mold)
-
Small cotton balls with 2-3 drops of pure essential oil (placed in a ventilated container)
Preventative Measures
-
Regular interior cleaning to address odor sources
-
Removing trash promptly
-
Using seat covers that can be washed
-
Leaving windows cracked when possible for ventilation
When to Seek Medical Help
If you or a passenger experiences symptoms after air freshener exposure, don't ignore them. Contact Poison Control (1-800-222-1222) immediately if:
-
Someone has ingested air freshener liquid
-
A child has swallowed air freshener beads
-
Irritation doesn't improve after removing the product
-
You experience breathing difficulties or severe headaches
