Air Fresheners: The Hidden Air Polluters In Our Homes

Air fresheners are commonly used to mask unpleasant odours and improve indoor air quality. However, despite their promise of clean and fresh scents, air fresheners can actually pollute the air and pose a range of health risks. From sprays and candles to incense and diffusers, air fresheners often contain a cocktail of chemicals, including volatile organic compounds (VOCs) such as formaldehyde, benzene, and toluene, which can irritate the eyes, nose, and throat, cause headaches and nausea, and have been linked to more serious health issues such as asthma and respiratory problems. With concerns about the impact of air fresheners on both human health and the environment, it is important to understand how these seemingly harmless products can contribute to indoor air pollution and explore alternative ways to improve air quality.

Air fresheners emit over 100 chemicals, including volatile organic compounds (VOCs)

Air fresheners are commonly used to mask unpleasant odours, but they can also be a source of indoor air pollution. They emit over 100 chemicals, including volatile organic compounds (VOCs) such as formaldehyde, benzene, toluene, ethylbenzene, and xylenes. These chemicals can have harmful effects on human health, including irritation of the eyes, nose, and throat, as well as headaches, nausea, and respiratory issues. Some air fresheners contain even higher levels of VOCs, which can lead to more severe health issues such as asthma attacks, neurological problems, and in some cases, different types of cancer.

The variety of air fresheners available on the market, such as sprays, candles, incense, diffusers, oils, and gels, all contribute to indoor air pollution. The fragrances and essential oils used in these products are chemical compounds designed to generate pleasant odours. These chemicals can react with naturally occurring compounds in the air, such as ozone, to form secondary pollutants. The types and amounts of secondary pollutants produced depend on factors such as the ingredients, concentrations, and usage of the air freshener.

The potential risks of air fresheners are not limited to their impact on indoor air quality. Some air fresheners contain toxic chemicals that can cause allergic reactions, skin irritation, and redness. Inhalation of air fresheners can lead to coughing, choking, and difficulty breathing, while swallowing them can result in minor irritation, nausea, vomiting, or even life-threatening effects. The toxic effects vary depending on the formulation of the product and the amount ingested or inhaled.

Environmental groups have repeatedly warned about the potential hazards of air fresheners to human health and the environment. Studies have linked the use of air fresheners to respiratory issues, reduced lung capacity, and asthma aggravation due to the combination of certain chemicals and ozone-forming properties. While the EPA has not issued advisories against air fresheners, they recommend careful usage and suggest natural alternatives such as proper ventilation, baking soda, coffee grounds, or lemon peels for odour elimination.

VOCs include formaldehyde, benzene, toluene, ethylbenzene, and xylenes

Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. They include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products, and air fresheners are among them.

VOCs are of concern as both indoor and outdoor air pollutants. The main concern indoors is the potential for VOCs to adversely impact the health of people exposed to them. Some of the health effects of exposure to VOCs include migraine headaches, asthma attacks, breathing and respiratory difficulties, dermatitis, and neurological problems. People with asthma or allergies can be more sensitive to scented products, and fragrances are known to cause allergic-type skin reactions.

The specific VOCs that are often found in air fresheners include formaldehyde, benzene, toluene, ethylbenzene, and xylenes. These chemicals can react with naturally occurring compounds in the air, such as ozone, to form secondary pollutants that worsen indoor air quality. The effects of air fresheners will vary depending on the chemicals in the product and who is exposed to them.

It is important to note that even ""natural" air fresheners made with essential oils are not necessarily free of potentially harmful chemicals. Essential oils are highly concentrated and can trigger allergic reactions.

To protect your health, it is recommended to limit exposure to products and materials that contain VOCs. Increasing ventilation and using fans can help reduce the concentration of VOCs indoors.

These chemicals can cause irritation to the eyes, nose, and throat

Air fresheners are designed to improve the scent of indoor environments, but they can also have unintended and unknown risks. They contain a variety of chemical and sometimes biological components that can be problematic for some individuals and can contribute to poor indoor air quality.

The chemicals in air fresheners can cause irritation to the eyes, nose, and throat. This is due to the presence of volatile organic compounds (VOCs) such as formaldehyde, acetaldehyde, benzene, toluene, ethyl benzene, and xylenes, which are often difficult to smell in the air. These VOCs can react with other compounds in the air, such as ozone, to produce secondary pollutants. The effects of these pollutants can vary depending on the chemicals in the product and the individual smelling them. People with asthma or allergies may be more sensitive to scented products, and reactions can worsen over time.

The toxic effects of air fresheners can also differ depending on the formulation. While inhaling small amounts of most air fresheners is usually not dangerous, brief exposure to spray air fresheners can cause coughing, choking, or difficulty breathing. Swallowing air fresheners can be more dangerous, causing minor irritation to the mouth, nausea, and vomiting. In high doses, swallowing liquid air fresheners can lead to drowsiness or intoxication.

The fragrances in air fresheners are also known to cause allergic-type skin reactions, including redness, rashes, and irritation. If air freshener gets in the eye, it can cause redness and irritation, but these effects typically resolve within an hour with thorough rinsing.

Some "natural" air fresheners made with essential oils may also contain highly concentrated, naturally-derived chemicals that can trigger allergic reactions.

They can also cause headaches, nausea, and respiratory issues

Air fresheners are known to cause a range of adverse health effects, including headaches, nausea, and respiratory issues. These effects can be caused by the various chemicals found in air fresheners, such as volatile organic compounds (VOCs) like formaldehyde, acetaldehyde, benzene, toluene, ethyl benzene, and xylenes. These chemicals can irritate the eyes, nose, and throat, leading to headaches and nausea.

Short-term exposure to these chemicals can cause coughing, choking, or difficulty catching one's breath, as well as eye and skin irritation. Prolonged exposure to high levels of VOCs has been linked to more severe health issues, including migraine headaches, asthma attacks, and neurological problems.

The toxic effects of air fresheners can vary depending on the formulation and the amount inhaled or ingested. Liquid air fresheners, when swallowed in small amounts, can cause nausea, vomiting, and drowsiness. Ingesting larger amounts can lead to intoxication. Inhalation of aerosolized air fresheners can also cause respiratory issues, especially for individuals with asthma or allergies.

The combination of certain chemicals in air fresheners and ozone-forming formaldehyde has been linked to reduced lung capacity and asthma aggravation. Environmental groups have repeatedly warned about the potential health risks of using air fresheners, and studies have found that many contain chemicals that can cause developmental and reproductive problems, especially in infants.

Some air fresheners contain fragrances that can cause allergic skin reactions

Air fresheners are commonly used to mask or remove unpleasant odours. However, they can contain a variety of chemical and biological components that can be problematic and contribute to poor indoor air quality.

The Environmental Working Group, a Washington-based nonprofit, found that over 75% of air fresheners contain either "likely" or "potentially significant" hazards to health or the environment. These hazards are based on concerns posed by exposure to their ingredients, which often include volatile organic compounds (VOCs) such as formaldehyde, benzene, toluene, ethylbenzene, and xylenes. These chemicals can react with naturally occurring compounds in the air, such as ozone, to form secondary pollutants, further worsening indoor air quality.

The use of air fresheners has been associated with elevated levels of VOCs in indoor air, which can irritate the eyes, nose, and throat, as well as cause headaches, nausea, and even more severe health issues. These effects may worsen over time with repeated exposure to air fresheners, and people can become more sensitive to scented products.

To avoid potential allergic reactions and health risks, consumers should carefully research the products they bring into their homes and opt for fragrance-free or natural alternatives to eliminate unwanted odours.
