photocatalytic filter

As the catalyst, titanium dioxide, receives ultraviolet rays contained in light, it decomposes and removes odorous substances into water and carbon dioxide.

Introduction of photocatalytic filters

The photocatalyst material receives ultraviolet energy and decomposes and removes harmful gases into water and carbon dioxide.


  • Titanium dioxide is a representative material.
  • It can be used in various applications due to its unique high oxidizing power, catalytic activity, high refractive index, and stability.
  • High oxidation power and 3.2 eV (anatase phase) bandgap make it applicable to photocatalytic technology.
  • Ultrafine particles can be uniformly coated on various supports such as glass, walls, and steel sheets by manufacturing a coating sol.
  • The photocatalytic decontamination method finally decomposes most organic compounds into water and carbon dioxide.
  • It has a semi-permanent life, can be reused, and is easy to maintain.
