Microalgae are microscopic unicellular organisms capable of photosynthesis, a natural process that consists of absorbing carbon dioxide (CO₂) and producing oxygen. In addition to purifying the air, they also filter fine particles and other pollutants, making them ideal for improving indoor air quality. Used in Bioteos technologies, microalgae allow effective purification while being part of a sustainable approach. This innovation combines ecological performance, renewability and a positive impact on human and environmental health.
