Beeswax releases negative ions when it burns. Pollen, dust, dirt, pollutants, and any other junk in the air all carry a positive charge, and that is how they can be suspended in the air. The negative ions released from burning beeswax negate the positive charge of air contaminants, and the neutralized ions are sucked back into the burning candle or fall to the ground. Many air purifiers and water filters harness this effective negative ion technology.
Because beeswax candles clean the air and reduce indoor pollutants, they can effectively reduce asthma, allergies, and hay fever.
