Cities are places full of opportunity and activity. But as more and more people migrate to urban areas, more infrastructure and transport are needed to keep up.  These developments generate harmful gases, emissions and particulate matter which pose a threat to our health.  We often don’t realise that our homes and offices could be affected by poor indoor air quality. The longer we’re exposed to poor conditions, the more likely we are to aggravate allergies and develop more severe respiratory diseases.

The good news is that innovation is keeping pace, and there are ways to keep our homes, and our health, safe.
