Candles are often used to neutralize unpleasant odours in homes. While some believe that the candle flame eliminates odours by burning oxygen molecules to which bad odours are attached, others argue that scented candles only mask bad smells with a stronger, more pleasant aroma. Scented candles contain essential oils or fragrances in their wax that evaporate and fill the air with volatile organic compounds when burned, covering up the original smell. In contrast, odour-eliminating candles use natural ingredients and essential oils to neutralize odours at the molecular level by breaking down odour-causing compounds. These candles provide longer-lasting freshness by addressing the source of the odour rather than merely masking it.

What You'll Learn
Scented candles mask bad smells with fragrance
Scented candles are a popular choice for masking bad smells with fragrance. While some candles are designed to neutralise odours, scented candles typically work by covering up bad smells with a stronger, more pleasant aroma.
The science behind this is that the heat from the candle flame helps to disperse the fragrance into the air, overwhelming the olfactory senses with a much nicer smell. This means that the original bad smell is still there, but you can't detect it.
For example, a user on Reddit shared that they use Fresh Wave candles and wax melts to eliminate food smells from their kitchen. They explained that these products are odour eliminators, not just odour maskers, and they work by preventing the food smell from spreading and lingering.
Another user on Reddit was looking for a candle to mask the smell of food in their room, as they eat with the door closed due to having roommates in a small apartment. They were recommended to try a candle with a foresty or earthy fragrance to cover up the food odour.
In addition to scented candles, there are also odour-eliminating candles that use natural ingredients and essential oils to neutralise odours at the molecular level. These candles don't just mask smells but help break down the odour particles, leaving your space smelling fresh. However, it's important to note that these candles might not work for everyone, as one user on a forum shared that they found an odour-eliminating candle ineffective in getting rid of a persistent bathroom smell.
Overall, while scented candles can be effective at masking bad smells with fragrance, odour-eliminating candles offer a more permanent solution by breaking down odour molecules and providing longer-lasting freshness.

Candle flames burn oxygen molecules, which carry bad odours
Candle flames burn oxygen molecules, which can carry bad odours. This process can help to eliminate unpleasant smells in enclosed spaces.
When a candle is burned, the flame consumes oxygen, reducing the overall amount of oxygen in the surrounding air. This combustion process can help to remove unwanted odours from the air by burning the oxygen molecules to which the odour particles are attached.
While candle flames can burn and reduce oxygen molecules, it is important to note that simply burning a candle may not completely eliminate all odours. The effectiveness of this method can depend on various factors, such as the size of the space, the intensity of the odour, and the duration of candle burning. In some cases, the odour particles may still remain in the air or settle in certain areas, even after the candle has been extinguished.
Additionally, it is worth mentioning that not all candles are created equal when it comes to odour elimination. Standard wax candles, whether scented or unscented, primarily mask odours by releasing pleasant fragrances that overwhelm the senses, making it difficult to perceive the original odour. These candles may not chemically alter or break down the odour-causing molecules in the same way that specialised odor-eliminating candles do.
Odour-eliminating candles, on the other hand, are designed to go beyond mere scent masking. They often contain natural ingredients, essential oils, and enzymes that actively neutralise and break down odour-causing molecules at a molecular level. When lit, the heat from the candle flame helps to disperse these odour-fighting ingredients into the air, allowing them to come into contact with and neutralise the unwanted odour molecules. This results in a more comprehensive and longer-lasting odour elimination compared to simply masking the smell.
In summary, candle flames do burn oxygen molecules, which can be effective in reducing unpleasant odours in enclosed spaces. However, for more robust and lasting results, specialised odour-eliminating candles that break down odour molecules at the molecular level may be a preferable option.

Some candles contain enzymes that break down odour-causing compounds
While some candles simply mask odours with their scent, certain candles are designed to eliminate odours. These candles contain enzymes that break down odour-causing compounds at a molecular level. This means that they provide longer-lasting freshness instead of just temporarily covering up the problem.
Odour-eliminating candles are made with natural, plant-based ingredients, such as activated charcoal, essential oils, and soy wax. Essential oils like tea tree, lemongrass, and pine are added for their natural deodorizing properties. When an odour-eliminating candle is lit, the heat from the flame helps disperse these odour-fighting ingredients into the air. As they circulate, they come into contact with and neutralize odour molecules, freshening up spaces.
To maximize the effectiveness of odour-eliminating candles, it is recommended to always trim the wick to about 1/4 inch before lighting. This helps the candle burn more evenly and reduces soot, making it a cleaner burn. For the first burn, it is also suggested to let the candle burn long enough for the wax to melt across the entire surface. This prevents tunnelling and ensures even burning in future uses. Additionally, placing the candle in the area where odours are strongest can help improve its effectiveness.
While odour-eliminating candles can be effective, it is important to note that some candles, especially those made with synthetic fragrances or paraffin wax, can release harmful chemicals when burned. These chemicals can cause various health issues, such as vertigo, headaches, mucosa irritation, respiratory problems, watery eyes, and chest tightness. Therefore, it is recommended to choose candles made from natural materials, such as beeswax or soy wax, and scented with essential oils rather than synthetic perfumes.

Essential oils in candles neutralise odours at a molecular level
While a candle flame cannot burn away or eliminate odours, scented candles can mask odours and give a space a pleasant aroma. Scented candles contain essential oils or other fragrances in their wax. When burned, the heat from the flame helps to disperse these oils into the air, filling the space with volatile organic compounds.
Essential oils are highly-concentrated plant extracts, distilled or otherwise extracted from various parts of a plant. They are called "essential" because they represent the "essence" of a plant's unique fragrance and properties. Essential oils are often used in candles for aromatherapy, to create a calming and relaxed atmosphere, or simply to freshen up a space.
Some common essential oils used in candles include citrus, lemon, lavender, tea tree, lemongrass, ylang-ylang, eucalyptus, and sweet orange. These oils can provide various benefits, such as stress relief, improved respiratory health, and antibacterial properties.
Odour-eliminating candles use essential oils that neutralise odours at a molecular level. These candles break down odour molecules and particles in the air, providing longer-lasting freshness than traditional air fresheners. For example, the enzymes in tea tree, lemongrass, and pine essential oils can break down odour-causing compounds, while the antibacterial properties of lemon oil can help to eliminate odours caused by bacteria.
To maximise the effectiveness of odour-eliminating candles, it is recommended to trim the wick before lighting, place the candle in the area with the strongest odours, and ensure proper ventilation.

Natural ingredients in candles can eliminate odours
While a candle flame cannot burn away odours, scented candles can mask them. Some candles contain natural ingredients that can eliminate odours, rather than simply masking them with fragrance. These candles are made with natural chemistry that absorbs and neutralises odour molecules as the candle burns.
Fresh Wave is a brand that offers candles and wax melts that eliminate food smells and other odours, such as those from pets, smoke, and mildew. These candles are made with real plant oils, including lime, pine needle, clove, cedarwood, and anise. The scent of these plants is noticeable when the candle is lit, but it dissolves as the odours are removed.
Fresh Wave's candles are made without harsh chemicals or synthetic fragrances, and they claim to leave behind a fresh, clean scent. They are made with hydrogenated soybean oil (soy wax) and a proprietary natural plant oil blend.
Another option for removing odours is to use plant-based gels, which can be left unattended to neutralise odours and freshen up a space. These gels are also made with plant oils and neutralise odours without releasing harsh chemicals or strong fragrances.
