Use beeswax candles – When burning, beeswax produces significantly fewer pollutants than wax made from paraffin or stearin.
The beeswax comes from the honeycomb of honey bees and is ideal for candles. Beeswax candles are more expensive than paraffin candles and so became less common then the cheaper version out of lower quality materials.
However, it is worth buying beeswax candles because they burn longer and are less harmful to our health.
LED lights instead of candles – Real candles should be replaced with electric candles, and not just for the sake of air quality. The electrical alternatives also help to ensure fire safety.
