Photocatalyst can produce more than 99% of resolving results to formaldehyde and organic matter under visible light. Because this course adopts contacting catalysis and oxidation principle, the catalyst composition plays a medium role, therefore the photocatalyst composition has no change, so does not need any treatment for using long time.

Features:
1) Main material: Foamed metal, photocatalyst, nickel
2) Utility function that the world initiates: Can be water-washed, the effect after water-wash will not decrease
3) Applications: Appliances that we can use filter screens such as air conditioner, and filter
