Air purification is a process that aims to remove air pollutants such as carbon dioxide (CO₂), fine particles, allergens, and volatile organic compounds. It improves air quality in enclosed spaces, such as offices, public transport or hospitals. Traditional technologies often rely on energy-intensive methods. Bioteos innovates with its devices using microalgae, which purify the air in a natural and sustainable way. These solutions contribute to the reduction of health problems associated with pollution, such as allergies or respiratory diseases, while having a reduced environmental impact.
