Does burning a candle clean the air?
Yes and no. Yes if it is pure beeswax. No, if it is not a pure wax. Candles made of pure beeswax will produce no smoke and cleanses the air around. It does this by releasing negative ions in the air. Such released negative ions bind with the toxins and remove them eventually from air. Also, natural pure beeswax burns slowly, when compared to paraffin candles and hence they last for long time.
