What You'll Learn
Plug-ins and candles may release harmful chemicals
Plug-ins and scented candles are popular ways to fragrance homes, but they may release harmful chemicals. According to toxicologists, plug-in air fresheners can expose you to potentially hazardous chemical compounds. One study by the EPA found that the reaction between certain fragrances in plug-ins, such as pine and limonene, and ozone creates a harmful smog inside homes. This smog contains formaldehyde, a known carcinogen, and other compounds that can cause respiratory issues.
Candles, especially scented or aromatherapy varieties, can also release toxic chemicals into the air. Many candles, particularly those made from paraffin or gel, are petroleum-based, and burning them releases toxic gases and soot, which can cause damage to your health and your home. Even if you opt for a candle with a cotton wick and natural wax, such as soy or beeswax, you should still be mindful of synthetic fragrances, which can be irritating, especially for those with allergies or asthma.
To avoid these issues, you can opt for healthier alternatives. Soy and beeswax candles are non-toxic and less likely to trigger allergies or asthma. Using natural fragrances, such as boiling spices or herbs on the stove or placing potpourri in a bowl, can also fill your home with pleasant smells without releasing harmful chemicals. Opening windows to let in fresh air is another simple way to keep your home smelling fresh without resorting to potentially toxic fragrances.
While plug-ins and scented candles can make your home smell wonderful, it's important to be aware of the potential health risks associated with them. By choosing healthier alternatives and being mindful of proper usage, you can reduce your exposure to harmful chemicals and create a safer and more pleasant indoor environment.

The dangers of indoor smoke
The use of scented candles and plug-in air fresheners is a common way to fill your home with pleasant aromas. However, recent studies have shown that these products can significantly contribute to indoor air pollution and pose potential health risks.
Candles
Candles, especially scented ones, can release toxic chemicals into the air when burned. The smoke from candles can linger in your home for an extended period, and the soot produced can cause damage to walls, appliances, and even your respiratory system. To minimize these risks, it is recommended to opt for candles made from natural waxes such as beeswax or soy, which produce less soot and are less likely to trigger allergies or asthma. Additionally, ensure that you follow candle safety guidelines, such as trimming the wick and avoiding prolonged burning.
Plug-in Air Fresheners
Plug-in air fresheners have gained popularity for their convenience and affordability. However, toxicologists warn that these devices can expose you to potentially harmful chemical compounds. The fragrances in plug-ins can react with ozone in the air to generate formaldehyde, a known carcinogen, and other compounds that can cause respiratory issues. The plastic components of these devices also contribute to environmental concerns, as they often end up in landfills and are challenging to recycle.
Alternatives for a Fresher Home
To avoid the dangers of indoor smoke, there are several alternatives to consider:
- Simmer pots: Boil water on the stove with ingredients like rosemary, lemon, cinnamon sticks, or nutmeg to naturally fragrance your home.
- Potpourri: Place dried herbs, flowers, and spices in a bowl for a natural and long-lasting scent.
- Fresh air: On pleasant days, open the windows to let in fresh air and improve indoor air quality.
- Natural candles: Opt for non-toxic candles made from soy or beeswax, which burn slower, cooler, and produce less soot.
- Essential oils: Pure, organic essential oils provide aromatic benefits without the same level of synthetic chemicals found in many candles and plug-ins.

Toxic candles and fossil fuels
Candles and plug-ins can be toxic in the home. Plug-ins can create harmful smog inside homes through the reaction between the plugin fragrances and ozone. These reactions generate formaldehyde, a known carcinogen, and other compounds that create respiratory problems. Candles, especially scented ones, can also burn toxic chemicals and release toxins into the air. The smoke from candles can get stuck in your home and take a long time to dissipate, further worsening indoor air quality.
Conventional candles are typically made from paraffin wax, a petroleum-based material and a byproduct of the oil industry. As a byproduct of fossil fuels, paraffin wax is highly unsustainable and contributes to environmentally devastating consequences such as oil spills, habitat destruction, and climate change. Burning paraffin wax releases toxic fumes, including formaldehyde, acetaldehyde, and polyaromatic hydrocarbons, which further contribute to the greenhouse effect and harm the planet.
To avoid the toxicity and environmental impact of traditional candles, consider switching to soy or beeswax candles. Soy candles are non-toxic, less likely to trigger allergies or asthma, and generally produce less soot. Beeswax candles are also less likely to trigger allergies as they do not produce toxins or soot when burned, but be sure to read the labels as some manufacturers add paraffin, which releases toxins. When choosing candles, opt for those made from non-GMO soy or ethical beeswax and scented with 100% essential oils. Additionally, look for candles in glass jars with organic cotton wicks to further reduce your environmental impact.
Instead of using plug-ins, try boiling ingredients like rosemary, lemon, cinnamon sticks, cloves, or nutmeg to naturally scent your home without releasing harmful chemicals. Potpourri is another alternative, using bulk herbs, dried flowers, and spices to create a natural fragrance. The best way to improve indoor air quality and achieve a fresh smell is to open the windows and let in fresh air, improving the ventilation in your home.

Safer alternatives to scented candles
Scented candles and plug-ins can release harmful chemicals, known as volatile organic compounds (VOCs), into the air. VOCs include irritants to the eyes, nose, and throat, such as formaldehyde, benzene, ethyl benzene, and xylenes. In addition, the open flame of candles poses a fire risk and candles without a flame can still produce smoke, which can be harmful.
Reed Diffusers
Reed diffusers are a longer-lasting alternative to scented candles. They typically consist of a vessel filled with fragrance oil and thin reeds. The reeds soak up the fragrance, which then evaporates into the air. A 6-ounce reed diffuser can offer fragrance for up to 4 months, while a larger 15-ounce reed diffuser can last up to a year.
Electric Wax Warmers
Electric wax warmers, also known as plate candle warmers, release fragrance without a flame. They melt scented candles or wax melts from the bottom up, preserving the wax and extending the life of the product. This method avoids the pollution caused by burning a candle and is suitable for use with renewable waxes and natural fragrances like essential oils.
Room Sprays
Room sprays made from essential oils are an eco-friendly way to fragrance your home. You can make your own blends with ingredients like vodka or witch hazel, or use natural ingredients like essential oils, to create seasonal scents without polluting the air.
Potpourri
Potpourri is an easy and effective way to scent your home. You can create your own blends using dried fruits, flowers, herbs, and spices, and place them in decorative jars, bowls, or cups. Potpourri can be tailored to your scent preferences and can be dark and earthy, sweet and floral, spicy, or refreshing.
Stovetop Simmer
Boiling water on the stove with added ingredients like rosemary, lemon, cinnamon sticks, cloves, or nutmeg is a simple way to fill your home with natural fragrance. This method is toxin-free and allows you to customize the scent to your liking.
Fresh Air
Opening windows on a sunny day to let in fresh air is a natural way to improve indoor air quality and create a pleasant atmosphere without the use of scented products.
These alternatives offer safer and more environmentally friendly options to scented candles and plug-ins, allowing you to enjoy fragrances in your home while reducing potential health and fire risks.
