๐จ Incense is the biggest indoor air polluter
Ohio eighth-grader Archishman Dey conducted a science project to check indoor PM2.5 pollution from five household sources. He tested an air fryer, candle, humidifier, gas, and incense in Solon, Ohio. Incense sticks produced the highest average PM2.5 concentration at 76.27 micrograms per cubic metre on the recorded date. This highlights that everyday activities can quietly introduce harmful, invisible particles into our homes. Dey suggests simple fixes like opening windows to improve indoor air quality.
