About indoor air pollution

Most of us know that when we’re outside, it can be harmful to breathe in polluted air. But air quality is important indoors as well. 

This is even more relevant if you’re living with a lung condition like asthma or chronic obstructive pulmonary disease (COPD).

We spend about 90% of our time indoors – at home, at work, at school, or when we go to shops or restaurants. So the quality of the air we’re breathing when we’re inside is really important. Poor indoor air quality has been linked to lung diseases like asthma, COPD and lung cancer.
