Indoor air pollution poses a significant threat as people spend the majority of their lives indoors. This problem, combined with outdoor pollution, results in 6.7 million premature deaths annually, according to the WHO. Poor indoor air quality not only leads to premature deaths but also impacts productivity, causes material damage, and increases healthcare costs. Health risks include stroke, heart disease, COPD, and lung cancer.

Indoor air pollutants encompass particulate matter, biological agents, and various chemicals. Prioritising health means opting for low-carbon emission products and addressing indoor pollution sources, such as fuel-burning appliances, building materials, and cleaning products, to safeguard against respiratory issues and long-term health problems.
