Car air fresheners are generally not safe to breathe regularly, as they often release volatile organic compounds (VOCs) and hazardous chemicals in a small, enclosed space. They frequently cause headaches, dizziness, and eye/throat irritation, and can trigger asthma attacks. Many contain undisclosed phthalates linked to hormone disruption and reproductive toxicity.
For People with Asthma and Allergies
For those with asthma or allergies, a car air freshener can be more than just a minor annoyance—it can be a major trigger. The synthetic fragrances and chemicals release Volatile Organic Compounds (VOCs) into the small, enclosed space of your car.
Yes, many synthetic car air fresheners contain chemicals that disrupt hormones. These products are heavily concentrated sources of Volatile Organic Compounds (VOCs) and phthalates, which are linked to reproductive issues, reduced sperm count, thyroid suppression, and developmental problems.
Yes, air fresheners can absolutely make you dizzy. This happens because they release a high concentration of Volatile Organic Compounds (VOCs), such as alkanes, alkenes, and sometimes formaldehyde.
Briefly inhaling a small amount of a spray air freshener might cause some coughing, choking, or difficulty catching one's breath. These effects should get better quickly with fresh air. Swallowing air freshener can cause toxicity ranging from minor irritation of the mouth to life-threatening effects.
Yes, air fresheners can be bad for your lungs. They emit Volatile Organic Compounds (VOCs) that irritate respiratory airways, worsen asthma, and trigger migraines. Some can even react with indoor ozone to form harmful airborne nanoparticles.
Toxic fume inhalation occurs when you breathe in harmful gases, vapors, or chemical particulates. Symptoms vary widely depending on the substance, but commonly include coughing, shortness of breath, throat and eye irritation, dizziness, and headaches. Immediate removal to fresh air is critical.
Air freshener poisoning—whether from inhalation, skin exposure, or accidental ingestion—can cause a variety of reactions ranging from mild irritation to severe toxicity. Common symptoms include respiratory distress, neurological issues like headaches and dizziness, and skin or eye irritation.
Air fresheners are bad for your health because they release a cocktail of unlisted chemicals and Volatile Organic Compounds (VOCs) that pollute indoor air. Instead of eliminating odors, they coat your nasal passages and release toxins that can trigger respiratory issues, hormone disruption, and other serious health problems.
The Hidden Dangers of Common Air Fresheners
Unfortunately, some of these chemicals can release volatile organic compounds (VOCs) into the air—compounds that have been linked to headaches, nausea, eye irritation, and even more serious health concerns over time.
Some commonly reported car freshener side effects include headaches, eye irritation, throat discomfort, or a feeling of heaviness during long drives. These effects are often linked to strong synthetic fragrances or excessive use.
According to the United States Environmental Protection Agency, mold exposure can cause eye and throat irritation, coughing, and sneezing – classic sick car syndrome symptoms. Sick car syndrome, also called toxic car syndrome, is a serious thing that can happen if there's condensation in your car's A/C system.
The healthiest way to scent your home is by using natural botanical sources rather than synthetic aerosols or plug-ins. The safest methods include simmer pots with fruits and spices, 100% pure essential oil diffusers (if you do not have pets), and naturally unscented beeswax candles.
The safest car air fresheners avoid synthetic fragrances, phthalates, and harsh propellants. Top non-toxic options include solid wood diffusers naturally soaked in essential oils, plant-based sprays, and smart diffusers with clean ingredients.
According to the Vehicle Codes of California, Arizona, Texas, Illinois, Minnesota, and Pennsylvania, it is illegal to hang objects such as air fresheners on a rearview mirror because it is considered to be a visual obstruction.
Fragranced products have been associated with a range of adverse health effects, such as migraine headaches, asthma attacks, respiratory difficulties, neurological problems, mucosal symptoms, and contact dermatitis (Kim et al.
There is some evidence that long-term use of air fresheners can affect heart function, especially in individuals who also have lung disease. We have learned, too, that air fresheners can affect a person's balance of hormones, which can impact reproductive health.
Baking Soda Deodorizer
Using baking soda instead of conventional deodorizers avoids harmful chemicals and keeps the air fresh. To make a baking soda deodorizer, fill a small bowl or jar with baking soda and place it in the desired area, or mix baking soda with a few drops of essential oil for added fragrance.
Air fresheners can impact indoor air quality by adding potentially hazardous pollutants to the air. The use of air fresheners is associated with elevated levels of volatile organic compounds (VOCs), such as formaldehyde, acetaldehyde, benzene, toluene, ethyl benzene, and xylenes, in indoor air.
Anyone can be affected by direct exposure to high levels of product. There are case reports of air freshener overdose from inhaling the spray at close range. This has caused rapid heartbeat that required hospitalization. 1,2 These cases have been caused by the butane propellant that is used to spray the product.
If it smells like rotten eggs, sewage, or burning, it may be dangerous. However, some dangerous fumes such as carbon monoxide have no odor at all.
Yes, many conventional air fresheners are toxic. They release volatile organic compounds (VOCs) like formaldehyde and hidden chemicals like phthalates, which are linked to hormone disruption and cancer. Constant use can trigger migraines, asthma attacks, and respiratory issues.
Signs or symptoms of poisoning may include:
Individuals who are accidentally exposed to toxic gases usually recover completely. However, sometimes acute life threatening or chronic severe complications may develop. Acute respiratory failure death is the most feared complications.
