What causes indoor air pollution and how can it be prevented?

Indoor air pollution can be caused by a variety of sources, including:

- Poor ventilation: Lack of proper ventilation in a building can lead to a buildup of indoor air pollutants.
- Combustion sources: Oil, gas, coal, wood, and tobacco products can all release harmful pollutants into the air when burned.
- Building materials and furnishings: Some building materials and furnishings can emit volatile organic compounds (VOCs) and other chemicals that contribute to indoor air pollution.
- Household cleaning products: Many common household cleaning products contain chemicals that can release pollutants into the air.
- Mold and mildew: Dampness and moisture in a building can lead to the growth of mold and mildew, which can release spores and other allergens into the air.

To prevent indoor air pollution, consider the following strategies:

- Improve ventilation: Make sure your home or building is well-ventilated to help reduce the buildup of indoor air pollutants.
- Use air purifiers: Consider using an air purifier with a HEPA filter to help remove pollutants from the air.
- Avoid smoking indoors: Smoking indoors can release harmful pollutants into the air, so it's best to smoke outside.
- Use natural cleaning products: Opt for natural cleaning products or make your own using ingredients like vinegar and baking soda.
- Fix leaks and moisture issues: Address any leaks or moisture issues in your home to prevent mold and mildew growth.
- Choose low-emission building materials and furnishings: When remodeling or furnishing your home, choose low-emission materials to help reduce indoor air pollution.
