Candles are a popular way to eliminate odours, but do they actually absorb and get rid of bad smells? There are two ways by which candles can help eliminate odours. Firstly, the flame from the candle wick will burn the oxygen molecules in the air, to which the bad odours are attached and travel. Secondly, scented candles will mask bad smells with a pleasant aroma, but they do not make the smells go away. Some candles are built to eliminate smells, such as Fresh Wave's odour-removing candle, which absorbs and neutralizes odour molecules as it burns, leaving a fresh, clean scent.

Scented candles mask odours
Scented candles are a popular way to eliminate unwanted odours from your home. While candles on their own can't remove odours, scented candles can mask unpleasant scents by covering them up with a more appealing fragrance. This method can be particularly effective in spaces like bathrooms and kitchens, where odours can easily linger.
The key to a candle's odour-masking success lies in its scent. Strong, fresh, and acidic scents like lemon, eucalyptus, and lemongrass are powerful enough to cover most bad smells. Citrus scents, in particular, contain the chemical compound limonene, which reacts with the receptors in your nose, masking nasty odours. Other effective scent options include spicy clove, citrusy bergamot, and aromatic eucalyptus.
Additionally, certain types of candles can help eliminate, rather than just mask, unpleasant odours. Beeswax candles, for example, purify the air by removing negative ions, while vegetable wax candles, made from natural and safe materials, can effectively eliminate unwanted scents without causing indoor air pollution.
To fully eliminate odours, it is recommended to light the candle before the activity that generates the smell and to keep it lit for a few minutes after the activity is done. This gives the candle time to dissolve and break down the odour molecules in the air.

Burning oxygen removes odours
Candles are a popular way to eliminate odours, but do they actually work? The answer is yes and no.
Firstly, candles can help to eliminate odours by burning oxygen. The flame from a candle wick will burn the oxygen molecules in the air, to which bad odours are attached and travel. This process draws air (including odour molecules) towards the flame, where the odours are annihilated, leaving behind carbon dioxide.
However, it is important to note that a single candle may not be able to burn all the odour molecules in a room, as these molecules diffuse throughout the space. Additionally, the candle flame itself has a smell, which may simply be covering up the original odour rather than removing it.
To effectively eliminate odours, some candles are designed to absorb and neutralize odour molecules as they burn. These candles often contain natural plant oils, such as lime, pine needle, clove, cedarwood, and anise, which dissolve odours and leave behind a fresh, clean scent. Beeswax candles are another option, as they purify the air while burning and remove negative ions.
It is recommended to light these odour-removing candles before an activity that generates a smell and to keep them lit for a few minutes after the activity is done to fully eliminate any lingering odours.
In summary, burning oxygen can help to remove odours, but the effectiveness of a candle in eliminating smells depends on the type of candle and the size of the space. While oxygen-burning candles may help to reduce odours, odour-neutralizing candles are specifically designed to absorb and eliminate smells.

Beeswax candles purify air
Candles can be used to eliminate or cover up bad smells in your home. Burning a candle will burn the oxygen molecules in the air, to which bad odours are attached, and scented candles can mask bad smells.
Beeswax candles have gained attention as an alternative to conventional paraffin wax candles due to their purported air-purifying properties. Beeswax is a natural substance produced by honeybees and is widely used for candle-making. It is claimed that burning beeswax candles can release negative ions, which bind to particles of pollution, pollen, and other toxins, thereby purifying the air.
However, there is limited scientific evidence to support these claims. While some studies have shown the potential benefits of negative ions, most of this research focuses on the effects of negative ions generated by air purifiers or natural settings, such as waterfalls and forests, rather than beeswax candles specifically. Professor Delphine Farmer, a specialist in Atmospheric Chemistry, has stated that there is "no evidence in the scientific literature that beeswax candles release negative ions".
While the air-purifying effects of beeswax candles are not conclusively proven, they do offer advantages over paraffin wax candles. Beeswax is a natural and renewable resource that burns longer, producing a brighter, cleaner flame with less soot. It also has a lower melting point, reducing the risk of accidental burns, and emits a pleasant, natural aroma without synthetic fragrances, making it a popular choice for individuals with sensitivities or allergies. Additionally, beeswax does not release toxic byproducts when burned, unlike paraffin wax, which can emit potentially harmful chemicals.
Therefore, while the extent of their air-purifying abilities remains uncertain, beeswax candles can still be a healthier and safer choice for those seeking to improve indoor air quality and enjoy the cozy ambiance of candlelight.

Natural plant oil candles absorb odours
Candles can be used to eliminate or cover up bad smells in your home. While candles themselves do not absorb odours, they can be used to burn oxygen molecules in the air to which bad odours are attached, thereby getting rid of them. Scented candles, in particular, can be used to mask bad smells.
Natural plant oil candles, also known as essential oil candles, are made from oils extracted from plants using methods like steam distillation or cold pressing. These oils provide naturally derived scents that are clean and authentic. Companies like Juniper Ridge utilise traditional steam-distillation techniques and sustainably sourced plants native to America's Western landscapes to create their essential oils. Fontana Candle Co. is another company that crafts clean-burning candles with essential oils and other natural ingredients like beeswax and coconut oil, without the use of synthetic chemicals.
Natural plant oil candles can be used to absorb and eliminate odours in your home, just like any other candle. However, it is important to note that candles scented with natural essential oils may not project their fragrances as strongly as artificially fragranced candles. If you are looking for a candle to mask odours, you may need to opt for a stronger, artificially scented candle.
On the other hand, natural plant oil candles offer a variety of benefits that make them a popular choice. These candles bring the scents of nature into your home and create a calming and relaxing atmosphere. They are also non-toxic and safe to burn, without the potentially harmful chemicals found in some artificially fragranced candles.
When choosing a natural plant oil candle to absorb and eliminate odours, consider the type of plant oil used and its scent. Some popular options include lavender, rose, sandalwood, citrus, and pine. You can also find candles made with blends of essential oils, creating unique fragrances. Additionally, pay attention to the wax type and choose a candle that is compatible with the essential oil used. Soy, paraffin, and blended waxes are common options, each with its own characteristics and performance.

Candles don't remove all odours
While candles are a popular way to eliminate odours, they do not remove all bad smells. Scented candles, for instance, merely mask unpleasant scents with a stronger fragrance. However, some candles are designed to eliminate odours and will keep your house smelling fresh.
Candles work in two ways to eliminate odours. Firstly, the flame from the candle wick will burn the oxygen molecules in the air, to which the bad odours are attached. Secondly, scented candles will cover up bad smells but not make them go away.
However, it is important to note that not all candles are created equal when it comes to odour removal. Some candles, such as beeswax and vegetable wax candles, are designed to eliminate unpleasant scents. Beeswax candles, for example, purify the air while they burn and remove negative ions in the air. They work by dissolving odour molecules on contact, breaking them down in the air, and preventing the smell.
Similarly, odour-removing candles made with real plant oils like lime, pine needle, clove, cedarwood, and anise, are designed to absorb and neutralize odour molecules as they burn, leaving behind a fresh, clean scent. These candles are also free of harmful chemicals, paraffin wax, phthalates, sulfates, and parabens, making them a safer and more natural alternative to traditional scented candles.
In conclusion, while candles can be effective at eliminating odours, they do not remove all bad smells. It is important to choose the right type of candle and follow the recommended usage instructions to ensure optimal odour removal. Additionally, eliminating the source of the odour is always the best solution, but when that is not possible, candles can be a helpful alternative.
