COSFE is powered by PtAg-PC — our next-generation photocatalyst. This proprietary multi-metal composite is engineered from carefully selected noble metals known for their exceptional catalytic activity, broad-spectrum light absorption, and long-term stability. When strategically combined, these materials create a powerful synergistic effect that significantly enhances photocatalytic performance, enabling rapid breakdown of harmful indoor air pollutants such as formaldehyde, benzene, and VOCs. This breakthrough technology is patent-pending in both Australia and the United States, with formal grant currently in progress.
