Many believe that scented candles are the biggest source of indoor air pollution.
However, new research reveals that flameless wax melts may be even worse—potentially releasing air pollutants on par with gas stoves and diesel exhaust. Here are the key findings from the study.
Flameless wax melts aren’t as harmless as they seem
Although marketed as a cleaner alternative to candles, the study found that heated wax melts release significantly more harmful particles into the air.
Scented products can pollute your home
The study builds on previous research showing that products like cleaning sprays and oil diffusers emit chemical compounds that degrade indoor air quality.

Researchers tested 14 different scented varieties
Wax melts infused with scents like papaya, lemon, and peppermint were examined to measure their impact on indoor air pollution.
Three times more particles than candles
Results showed that scented wax melts emitted three times more ultrafine particles than traditional candles.
Pollution levels comparable to gas stoves
The concentration of harmful nanoparticles was found to be similar to those produced by gas stoves and diesel engines—an alarming discovery.
Unexpected chemical reactions create pollution
Researchers found that fragrance compounds in wax melts interact with indoor ozone, forming nanoparticles that could pose health risks.

Unscented wax melts were not a problem
Interestingly, unscented wax melts produced no significant air pollution, suggesting that the issue stems primarily from added fragrances.
Nanoparticles may pose health risks
Prior research has linked inhalation of nanoparticles to respiratory irritation, cardiovascular issues, and other adverse health effects.
Ventilation is crucial
Experts recommend using wax melts in well-ventilated spaces or investing in an air purifier to reduce exposure to airborne pollutants.
Consider fragrance-free alternatives
Many scented products contain unregulated chemicals. Consumers looking to avoid exposure should opt for fragrance-free options.
