Can Japanese photocatalyst in addition to formaldehyde still be used? Always open the window for ventilation, and stay occasionally for a day or two recently. It's cold and foggy now.

Photocatalyst needs enough light to play its role, and the damage of membrane will cause secondary pollution, which is unsafe to use. Photocatalytic materials originated in Japan, and their application in Japan is not air treatment. In fact, it was not used in Japan at that time. The industrial use was hydrogen production, and the civil use was self-cleaning sterilization. I'm just worried that there will be secondary pollution, insufficient reaction and insufficient ultraviolet rays. Although it has been upgraded now, this problem has not been well solved.

Light green pigment can be used, which is a new material developed on the basis of photocatalyst. Without the participation of light, it can be directly decomposed with formaldehyde, and can penetrate into the interior of the board to achieve the effect of root decomposition without secondary pollution. Extracted from plant extracts, it is safer for families with baby mothers at home. It is also widely used by formaldehyde treatment companies and is more and more loved by consumers.
