Key Facts About Indoor Air Pollution

• Indoor Air Quality (IAQ) affects health and comfort.
• Common pollutants include carbon monoxide, formaldehyde, and asbestos.
• Outdoor Particulate Matter (PM2.5) deteriorates IAQ.
• Indoor activities like cooking and smoking increase pollution.
• Overcrowding in cities raises pollutant levels.
• Lack of awareness allows harmful practices to persist.
• India has the highest indoor PM2.5 levels globally.
• Household air pollution causes 3.2 million deaths annually.
• Poor ventilation leads to “sick building syndrome”.
• Linked to diseases like stroke and lung cancer.
• Air purifiers with HEPA filters can improve IAQ.
• Indoor plants can absorb harmful pollutants.
• Transition to clean fuels for cooking and heating is essential.
• Use of low-VOC materials improves air quality.
• Health-focused building practices are crucial.
• Indoor air pollution is a growing concern in urban India.

India's Indoor Air Quality Challenge

Indoor air pollution is a significant health and environmental issue in India, contributing to the country's broader goals of improving public health and sustainable urban living. The high levels of indoor pollutants are linked to India's rapid urbanization and industrialization, which exacerbate overcrowding and inadequate ventilation. Internationally, India ranks among the highest in terms of indoor PM2.5 levels, necessitating urgent action to align with global health standards and improve the quality of life for its citizens.
