Despite these precautions, some consumers express concerns about potential toxins released during burning, such as volatile organic compounds (VOCs) and particulate matter. However, Nest maintains transparency about their ingredients and manufacturing processes to reduce these risks.

Potential Emissions from Burning Nest Candles

When candles burn, incomplete combustion can release various compounds into the air. These may include:

  • Volatile Organic Compounds (VOCs): Such as benzene and toluene, which are known irritants and potential carcinogens at high levels.
  • Particulate Matter (PM): Tiny particles that can penetrate respiratory systems and cause irritation.
  • Carbon monoxide (CO): A colorless, odorless gas that can be harmful in enclosed spaces.

The emission levels depend on several factors:

  • Type of wax used (natural waxes tend to produce fewer toxins).
  • Quality and safety of fragrance oils.
  • Wick composition and length.
  • Burning environment (ventilation, candle size, and container).

Nest candles, by using high-quality waxes and lead-free wicks, generally produce lower emissions compared to lower-grade candles. However, any candle can produce some pollutants when burned improperly or in poorly ventilated areas.
