Many of us know that burning candles made from paraffin waxes can emit soot, smoke and other pollutants into the air. So it may seem natural that burning a different type of candle can improve your indoor air quality. A recent medical study revealed that burning pure beeswax candles not only provides a pleasant honey scent, it also releases negative ions into the air. These help remove pollution like dust, pollen, toxins and smelly odors. This helps purify and clean the air because the negative ions force the pollutants to literally fall to the ground -- making vacuuming even more important.
