Outdoor air pollution :

• Outdoor air pollution is caused by commercial and industrial sources. These sources are usually concentrated in big cities. The main producers of dangerous gases are factories and transport.

Indoor air pollution

We also cause it at home with the products we use. Air indoors can be polluted by cleaning products, dust, paint, insect sprays, cigarette smoke or from cooking.

Some pollutants such as smoke and insect sprays can cause problems such as asthma.

To reduce air pollution at home you should open the doors and windows 2-3 times a day, use natural cleaning products, and do not allow smoking.
