Are Air Fresheners Beneficial or Harmful to Our Health?

Air fresheners are widely used in enclosed spaces such as homes, offices, schools, hospitals, and transportation vehicles, where their use is particularly concerning due to limited space and poor ventilation. Although they are marketed as products aimed at improving indoor air quality, air fresheners can emit potentially harmful chemicals that pose health risks (Steinemann, 2017).

What Do Air Fresheners Emit?

Air fresheners release volatile organic compounds (VOCs), which can include terpenes and secondary pollutants such as formaldehyde, acetaldehyde, and benzene. Terpenes react with ozone to produce formaldehyde, which can lead to indoor air quality issues.

Health Effects Associated with Air Fresheners

Exposure to air freshener emissions can cause health problems such as migraines, respiratory issues, irritated mucous membranes, asthma attacks, and others. Certain VOCs emitted by air fresheners are classified as toxic or hazardous.

Who is Affected by Air Freshener Use?

A significant portion of the population reports health problems related to exposure to air freshener emissions, with vulnerable groups including individuals with asthma, allergies, and chemical sensitivities.

“Green” Air Fresheners

There are also air fresheners marketed as green, organic, or natural. However, there is no regulatory definition for these categories. As a result, these products often do not differ significantly in terms of harmful emissions from conventional air fresheners.

Labelling of Air Fresheners

Labels on air fresheners typically do not list all ingredients based on available testing. Studies show that even most ingredients, including hazardous ones, are missing from labels and safety data sheets.

Involuntary Exposure to Air Fresheners

Involuntary exposure in public spaces can cause negative health effects and restrict access for sensitive individuals. Research indicates a preference for scent-free environments in public spaces such as restrooms, airplanes, and hotels.

Possible Solutions or Alternatives

Reducing or eliminating sources of indoor pollutants, improving ventilation, and implementing “scent-free” policies can help mitigate the risks associated with air fresheners. Increasing public awareness and clearer ingredient labelling are also crucial.

Air fresheners are widely used but carry hidden risks to indoor air quality and health. Addressing these issues through research, public awareness, and policy can help create a safer indoor environment (Steinemann, 2017).
