Candles are a popular way to eliminate unwanted odours, including cigarette smoke. They are believed to work by using the high temperature of the flame to promote the oxidation of odour-causing compounds, such as tar, into odourless carbon dioxide and water. In addition, candles with natural enzymes can neutralise foul odours, and scented candles can mask the smell of smoke. However, the effectiveness of candles in eliminating cigarette smoke is questionable, as proper ventilation and deep cleaning of affected areas are often required to truly remove smoke odours. Furthermore, burning candles made from paraffin wax can pose potential health risks due to the release of soot and other chemicals into the air.

Candles as a 'thermal reactor'
Candles can help eliminate cigarette smoke by acting as a thermal reactor. The high temperature of a candle flame, which can reach around 1400°C, promotes the oxidation of odour-causing compounds in the smoke, such as tar, and converts them into odourless carbon dioxide and water. This process essentially burns away the smelly compounds in cigarette smoke before they have a chance to stick to walls, ceilings, and furniture.
However, it is important to note that the total amount of heat produced by a candle is relatively small, and a single candle may not be sufficient to effectively eliminate cigarette smoke odours. Additionally, burning candles, particularly those made from paraffin wax, can release potentially harmful chemicals into the air and pose health risks, especially for individuals with asthma or breathing issues.
To enhance the effectiveness of candles as a thermal reactor, it is recommended to use multiple candles simultaneously. Additionally, ensuring proper ventilation and using candles in conjunction with other methods of odour elimination, such as air purifiers or deep cleaning, can improve their ability to eliminate cigarette smoke odours.
While candles can help reduce cigarette smoke odours, it is important to emphasise that the most effective way to eliminate tobacco odours is to avoid smoking indoors altogether.
CANDLE Reactors
The term "CANDLE" in the context of reactors refers to an innovative reactor design strategy known as Constant Axial shape of Neutron flux, nuclide densities, and power shape During Life of Energy production. This strategy offers several advantages over conventional fast reactor designs. One of the key benefits is that reactor characteristics remain constant throughout the energy production process, eliminating the need for reactivity control mechanisms during burn-up. This design also allows for easy extension of the reactor's life by increasing the core height and using natural uranium as fresh fuel.
CANDLE reactors have been studied extensively, particularly in the context of small-scale and medium-sized reactor concepts. These reactors aim to utilise natural uranium as fuel and have been considered for both metallic fuel and gas-cooled configurations. The feasibility of these designs has been assessed, taking into account factors such as fuel form, coolant material, and thermal hydraulic aspects. The optimisation of the CANDLE burn-up scheme has enabled the development of medium-sized gas-cooled fast reactors with a capacity of 1000 MWt, capable of operating for 10 years without refuelling or fuel shuffling.

Odor-neutralizing enzymes
Smoke odor candles, also known as smoker's candles, are designed to remove tobacco smells from various environments, including cars, homes, and clothes. They contain enzymes that neutralize odors from smoke, pets, or other unwanted smells.
The natural odor-neutralizing enzymes in these candles attack and remove foul odors from the air. The enzymes absorb the odor from their surroundings, break down the odor's compound structure, and release a pleasant fragrance. This process involves the enzymes absorbing the odor molecules, which are then broken down into smaller, odorless components through a microbial action. The by-products of this process are then evaporated as clean, natural gas.
Smoke odor candles are more effective than traditional scented candles, but they are most effective when combined with other methods of odor removal. For example, it is recommended to use them alongside proper ventilation and deep cleaning of affected areas, including cloth-covered furniture, carpets, and walls. Additionally, smoke odor candles should not be burned for more than four hours at a time, as this can increase soot production as the wax liquefies.
While smoke odor candles can be effective in reducing cigarette smoke odors, it is important to note that they may not completely eliminate all traces of smoke. Preventative measures, such as proper ventilation and the use of air purifiers, can be more effective in managing smoke odors.

Activated carbon
Candles can help eliminate cigarette smoke, but they are only a temporary solution. The high temperature of the candle flame promotes the oxidation of odour-causing compounds (such as cigarette tar) to odourless carbon dioxide and water. Candles are therefore most effective when burned while smoking, as they can eliminate some of the smoke before the tar sticks to walls, ceilings, and furniture.
The effectiveness of activated carbon in removing compounds from cigarette smoke depends on several factors, including the activity, amount, and distribution pattern of the carbon. It can also depend on the vapor pressure, molecular weight, and polarity of the compound.

Temporary smoke smell solution
Candles can be an effective way to temporarily mask the smell of cigarette smoke. While they do not eliminate the smell completely, they can help to reduce it and make it less noticeable. Here are some ways in which candles can be used for this purpose:
Use smoker's candles
Also known as "smoke odor exterminator candles", "smoke eater candles", or "smoke eliminator candles", these candles are designed to remove smoke smells. They contain more chemicals than regular candles, which allow them to neutralize some of the harmful elements in cigarette smoke odors while providing a pleasant scent. These candles work by using activated carbon, which absorbs smoke particles from the air. The high temperature of the candle flame also promotes the oxidation of odor-causing compounds such as cigarette tar, turning them into odorless carbon dioxide and water.
Combine with other methods
Smoker's candles can be used in combination with other methods of eliminating cigarette smells, such as Febreze or air purifiers. Using an air purifier and an exhaust fan is a more effective method of getting smoke out of the air than lighting a candle when smoking indoors. However, it is important to research the ingredients in any air purifier or freshener before use, as some may not be safe to breathe in for prolonged periods, especially for those with asthma or breathing issues.
Ensure proper ventilation
Proper ventilation is key to preventing the buildup of smoke and odors. Open windows and doors to allow fresh air to circulate and disperse the smoke. This will also help to prevent smoke particles from settling on walls, furniture, and other surfaces.
Burn during and after smoking
For maximum effectiveness, it is recommended to burn smoker's candles during and after smoking. This can help to eliminate some of the smoke before it has a chance to stick to walls, ceilings, and furniture. However, it is important to note that burning a candle for more than four hours can increase soot production as the wax liquefies, so be sure to follow the manufacturer's instructions.
Use multiple candles
To thoroughly eliminate cigarette smoke odors, it is recommended to use at least two or three smoker's candles in the affected area. This will help to ensure that the candles are more effective in removing the smoke particles from the air.

Health risks of candles
While candles can help eliminate cigarette smoke, there are potential health risks associated with their use. Candles are made from a variety of materials, including paraffin wax, beeswax, soy wax, and palm wax. Paraffin wax is a petroleum byproduct, and burning it can release harmful gases and pollutants such as formaldehyde, carbon monoxide, nitrogen oxide, carbon dioxide, and volatile organic compounds (VOCs). These pollutants can be higher than background levels and contribute to indoor air pollution, which is a common health issue.
The dyes and artificial scents in scented candles can also be a cause for concern. The dye used in candles often contains benzidine, which has been linked to an increased risk of bladder cancer. Additionally, scented candles can release VOCs, which may increase the risk of cancer. Candle chemicals, fragrances, and wax are known asthma and allergy irritants, and exposure to candle smoke can trigger asthma attacks and allergic reactions.
However, it is important to note that the scientific community is divided on the impact of candle emissions on human health. Some argue that the amount of particulate matter released from burning candles is not enough to cause health problems, and that proper ventilation can further minimize potential risks. Higher-quality candles made from natural materials, such as beeswax or soy wax, are generally considered safer as they produce less soot and toxic chemicals.
To minimize potential health risks, it is recommended to choose candles made from natural materials, ensure proper ventilation when burning candles, and follow candle safety guidelines to prevent accidents. While candles have therapeutic benefits, it is essential to be mindful of the potential risks and take appropriate precautions.
