Air pollution kills around 7 million people each year. Most of these deaths occur in developing countries, where solid fuel is often burned in poorly ventilated spaces. However, between 26,000 and 38,000 of those deaths occur in the UK.
People in the UK spend over 80% of their time indoors, whether at home, at work, at school or commuting. So making sure the air inside those enclosed spaces is safe to breathe is crucial.
