Minimize Indoor Pollution From Candles

Although candles create a warm, inviting feeling within the home during the holidays and throughout the year, there are studies showing that candle usage can create problems for your home’s interior.

Burning candles can emit small amounts of toxins such as acetone, benzene, lead and mercury into the air. Normal use of candles should not pose a health hazard. Large quantities of these toxins, however, may prove to be harmful. 

Candle emissions can also leave dark shadows (ghosting) or soot on walls, on furniture and in the heating and cooling system, often costing homeowners thousands of dollars to fix.

• Because many scented and slow burning candles may contain metals, consumers should look to see if the core of the wick is shiny metal. If you see metal, do not burn, or check with the manufacturer.

• When you do burn candles, keep the wicks cut short to one-quarter of an inch.

  The longer the wick, the larger the flame, the brighter the candle, the more the soot.

• Keep candles away from drafty places. Wind will blow soot and toxins into the air and cause inefficient burning, a cause of smoking or sooting.

• Do not shake or tip candles because the candle can smoke and send soot into the air to land on walls, carpets and furniture.

• Keep candles in places away from children and pets. Besides fire hazard, small children and animals may accidentally disturb a candle, causing it to smoke and release soot.

• Avoid putting small children directly on carpet. Lead and other pollutants from candles are attracted to synthetic fibers often used in upholstery and carpeting.

• Refrain from burning scented or slow-burning candles that have additives. Look for candles, such as bees wax, that do not contain high levels of pollutants.

• Keep your home clean. Vacuuming may just recirculate particles unless you use high-performance vacuum bags that catch micro particles.

• Use a good filtration system on your furnace that attracts micro particles. High performance furnace filters minimize the level of pollutants that circulate throughout your home. Changing filters more frequently will help reduce the amount of micro particles in the home.

• Be aware of candles and holiday products that have been recalled by the U.S. Consumer Product Safety Commission. This information can be found at www.cpsc.gov.
