A study, published in Environmental Health Perspectives, found that people with relatively high blood concentrations of 1,4-dichlorobenzene, show signs of reduced lung function. This chemical is found in air fresheners and toilet deodorizers.

It is important that you know how to choose a non-toxic air freshener plug-in so you don’t have to worry about what you’re inhaling. Read on because this guide has everything you need to know!

Are There Any Plug-Ins That Are Non-Toxic?

Yes, there are many chemical-free non-toxic air freshener plug-in available. In fact, we have a list of 15 of the best and safest plug-ins that will freshen up and deodorize your home, office, or commercial establishment. 

Are Plug-In Air Fresheners Toxic?

Plug-in air fresheners function through heat induction technology. It activates scented gel that releases fragrance continually until the product has been consumed. 

Researchers have found toxic chemicals in some plug-in air fresheners:

  • Benzene – a carcinogen commonly used to make nylon, plastic, resin, and synthetic fiber. 
  • Formaldehyde – colorless, highly toxic, and flammable gas used as a preservative in food and many household products.
  • Phthalates – comprise chemicals commonly used to manufacture plastic to make it more durable. 
  • Toluene – naturally found in crude oil, this compound is used in the production of glues, paints, and even explosives. 
  • Xylene – organic compound often combined with benzene and toluene to form BTX aromatics. 
  • Volatile organic compounds (VOCs) – chemicals often used to produce paints, refrigerants, and various medicines. 

According to the Made Safe organization, “Because they contain ingredients that are associated with various health effects, our constant exposure to air fresheners is cause for concern. Researchers have measured and identified air freshener chemicals that are linked to cancer, neurotoxicity, and effects from endocrine disruption.”

Is There Such a Thing as a Non-Toxic Air Freshener?

Yes, there are many non-toxic air fresheners out there, some of them made with organic and natural ingredients.

But when it comes to plug-ins, finding non-toxic options requires due diligence. You need to read the labels—the mechanisms may require certain chemicals to function correctly. 


Look for EPA-Certified Safer Choice, Green Seal, Greenguard, and MPI Extreme Green labels. These certifications have stringent testing requirements for allowable concentrations of harmful chemicals.

How Do You Make a Non-Toxic Air Freshener?

Naturally aromatic plants indoors to ensure fragrance without the need for chemicals. You can make dried herbal potpourri and put them in most corners of the home to get a muted yet natural aroma. You can also create a DIY spray using natural essential oils. 

For non-toxic air freshener plug-in products, we have a list of the 15 most aromatic and safest plug-ins for your home or office:
