The Safest Non-Toxic Air Fresheners for The Home and Car.

I have an affinity for beautifully scented homes. No, really, the moment I walk into a room, the first thing I notice is its scent!

From cozy winter evenings wrapped in the warm embrace of cinnamon and cloves to refreshing summer mornings filled with the refreshing aroma of citrus, there’s something truly magical about having a scented house. 

But have you ever stopped to consider the health impacts of using traditional air fresheners to achieve this aromatic ambiance? 

I’ve smelled more than my fair share of air fresheners in my lifetime. And let me tell you, I can spot the cocktail of synthetic chemicals from a mile away. You know exactly what I’m talking about – those overpowering and cloying scents that can be described as simply “unnatural.” 

The synthetic scent of artificial flowers or a sickly sweet aroma reminiscent of candy-coated chemicals gives me headaches. I’ve also experienced respiratory irritation which is another common adverse health effect. 

What are the most toxic chemicals in air fresheners?


Phthalates are a group of chemicals commonly used as fragrance carriers in air fresheners and other scented products.

These harmful chemicals have been linked to hormone disruption, reproductive issues, and developmental abnormalities.

Human studies have also suggested associations between phthalate exposure and adverse health effects, including asthma, allergies, and decreased lung function.  

Check out the ingredient list for names such as: 

  • Diethyl phthalate (DEP)
  • Dimethyl phthalate (DMP)
  • Di-n-butyl phthalate (DBP)
  • Di(2-ethylhexyl) phthalate (DEHP)

Volatile Organic Compounds (VOCs)

VOCs are yet another diverse group of chemicals that easily evaporate into the air, contributing to indoor air pollution.

Found in many air fresheners, home decor, and paints, VOCs can react with other chemicals in the atmosphere to form harmful pollutants, such as ozone and fine particulate matter.

Prolonged exposure to VOCs has been associated with a range of adverse health effects, including headaches, dizziness, nausea, respiratory irritation, and exacerbation of asthma symptoms.

Also, certain VOCs, such as formaldehyde and benzene, are known carcinogens, increasing the risk of cancer with long-term or high-level exposure.

Check out the ingredient list for names such as: 

  • Formaldehyde
  • Benzene
  • Toluene
  • Xylene
  • Ethylene glycol
  • Acetone
  • Ethylbenzene
  • Limonene (although naturally occurring, it can react with ozone to form harmful secondary pollutants)

Synthetic Fragrances

Synthetic fragrances are complex mixtures of chemicals designed to mimic natural scents and enhance the aroma of air fresheners and other products.

However, many of these fragrance ingredients are derived from petrochemicals and can contain hundreds of individual compounds, including phthalates, VOCs, and allergens.

Synthetic fragrances have been linked to allergic reactions, skin irritation, respiratory issues, and exacerbation of asthma symptoms in sensitive individuals.  

Check out the ingredient list for names such as:

  • Benzyl acetate
  • Ethyl acetate
  • Ethanol
  • Linalool
  • Coumarin
  • Alpha-pinene
  • Beta-pinene
  • Limonene (synthetic versions)
  • Geraniol

According to this study, 34.7 % of the USA population reported health problems, such as migraine headaches and respiratory difficulties, when exposed to fragranced products. 

On top of that, 15.1% have lost workdays or a job due to fragranced product exposure in the workplace. 

So, what’s the alternative?

How can I make my own non-toxic air freshener at home?

If you want to create a DIY non-toxic air freshener for every room of the house, we have an easy recipe for you:

  1. Start by choosing your favorite essential oil or blend of oils – lavender, lemon, peppermint, and eucalyptus, just to name a few options.
  2. Fill a clean spray bottle with distilled water. You can typically find spray bottles at your local grocery store or online.
  3. Add around 10-20 drops of your chosen essential oil(s) to the water. The number of drops will depend on your personal preference and the strength of the scent you desire.
  4. Optional: You can add a splash of witch hazel or vodka to the mixture. This helps emulsify the essential oils with water and can extend the shelf life of the spray.
  5. Close the spray bottle tightly and shake well to mix the ingredients thoroughly.
  6. Your natural air freshener spray is now ready to use! Simply spritz it into the air whenever you want to freshen up your space.

This was your full guide to toxic-free air fresheners!

Unlike traditional formulas that are over-packed with nasty chemicals, toxic-free air fresheners won’t cause respiratory irritation, allergies, and other adverse health effects. 

Heavenly-scented essential oils offer a wide range of delightful natural scents derived from plants, allowing us to customize our sensory experience and uplift our mood without compromising on safety. 

Personally, I use my non-toxic air freshener plug-in every day. However, if you aren’t as obsessed with scents as I am, you can always save it for special occasions. 

One thing is certain, with a non-toxic diffuser, you can enjoy the benefits of a fresh-smelling home without compromising your well-being.
