## The Hidden Problem with Candles

The black marks candles leave on walls are often blamed on poor quality. However, these marks are related to how the candle burns. As the wick grows longer and the burning time increases, black soot particles form and stick to the walls.

## The Source of Soot

When candles burn, black lumps accumulate at the wick tip, producing soot. This soot is similar to particles from car exhaust and negatively affects indoor air quality. Candles burned for long periods produce more soot.

## Air Quality Hazard

Incorrect candle burning releases fine dust particles called PM2.5 into the air. These particles can reach the lungs and cause health issues. Indoor air quality worsens in enclosed spaces.

## Proper Burning Techniques

To ensure candles burn properly, the wick should be trimmed to ¼ inch (6 mm) before each lighting. This keeps the flame small and steady. Additionally, candles should not burn for more than 3-4 hours and should be kept away from drafts.

## Extending Candle Life

The habit of trimming the wick can extend a candle's life by up to 25%. Proper burning also prevents marks on walls and ensures cleaner indoor air.

## A Healthy and Clean Environment

Burning candles correctly keeps your home clean and maintains indoor air quality. These simple steps help create a healthier and more enjoyable environment.
