Abstract
Nothing is more fundamental than the air we breathe. Taking place every year on the 8 November is World Ventil8 Day. This day aims to raise awareness of the importance of ventilation as a crucial part of enabling health and wellbeing. Breathing clean air is so often ignored or poorly understood – and we usually only notice when there is a problem. Good ventilation not only reduces our exposure to air pollutants and infectious diseases, it also enables us to think more clearly, sleep better and be more productive. Aotearoa NZ lags behind comparable countries on indoor ventilation standards.
