Our proprietary Nafitec™ technology was applied to develop a deodorization filter with a photocatalyst supported on a metal material.
It has excellent effects such as high deodorization efficiency, low pressure drop, high strength, and light weight.

We have developed a deodorization filter that has a higher ammonia decomposition rate at low temperatures than conventional technologies, a high nitrogen selectivity, and does not produce environmentally harmful nitrogen oxides.
Efforts are currently underway for practical application.

We have developed a catalyst that can break down ethylene gas and other gases that affect the freshness of fruit and vegetables into water and carbon dioxide at room temperature.
This practical, filter-shaped catalyst body for freshness retention can be effectively used to keep fruit and vegetables fresh.
