91% of the world's population lives in places where air quality guidelines are not met. We spend between 70 and 80% of our time indoors, and the quality of the air we breathe has direct consequences for our health.
Air pollution represents a significant risk to human health, as together with other factors it can cause cardiovascular accidents, lung cancers and chronic respiratory conditions such as asthma. Therefore, the lower the pollution levels in cities, the better the cardiovascular and pulmonary health of the population.
According to the World Health Organization, 80% of cities worldwide, in both developed and developing countries, far exceed the pollution levels established as safe, and 91% of the world's population lives in places where air quality guidelines are not respected.
We spend between 70 and 80% of our time indoors. Poor air quality at home or in the office can lead to allergies, infectious or irritative conditions, particularly in more sensitive individuals such as those who already suffer from respiratory or cardiac conditions, older people, or children.
According to the Barcelona Institute for Global Health, if pollution levels in the city could be reduced to those recommended by the WHO, 659 premature deaths would be avoided each year, representing an increase of 47 days in the life expectancy of its citizens.
That is why it is important to breathe clean, renewed air at least in our home and workplace, and to maintain low CO₂ levels during the night.
The double-flow ventilation system ensures that air quality remains fresh, clean and free of odours, while at the same time guaranteeing that CO₂ levels stay close to 400 ppm — the current global level. Furthermore, this double-flow ventilation system allows the aerothermal system that heats and cools the home according to the season to do so more efficiently and with lower energy consumption.
