Indoor air is 5 to 10 times more polluted than outdoor air. Cromology has developed a new technology designed to permanently neutralise major indoor air pollutants such as formaldehyde (CH2O). This toxic substance can irritate the eyes and airways, induce allergic reactions and also cause rhinitis and asthma attacks. Up to 80% of targeted pollutants are eradicated when the ceiling and the four walls are painted with this depolluting paint. The effect lasts during the entire paint life cycle.
