PCF® Photocatalytic Deodorizer
Solving odor at the source. Next-generation deodorization technology for a zero-emission, carbon-neutral future.
Odor is a serious business issue that lowers productivity, harms customer satisfaction, and affects employee health. While conventional methods are limited, the PCF® photocatalytic deodorizer addresses the root cause by mineralizing odor-causing compounds through photocatalysis, delivering lasting results. It is ideal for shopping malls, schools, food processing plants, and resort hotels. By decomposing odorants into carbon dioxide and water at the filter surface and reducing reliance on consumable chemicals and disposable media, PCF® lowers environmental burden and contributes to zero-emission and carbon-neutral initiatives.
How it works
How it works
Photocatalysis uses light to oxidize and break down odorous compounds. Traditional approaches rely on adsorption or neutralization. By contrast, photocatalysis generates reactive oxygen species that contact the odor source and decompose it. In the PCF®, air drawn from exhaust ducts passes through photocatalytic filters from left to right. Odorants accumulate on the filters and are oxidized under 360 nm UV light, breaking down harmful compounds into carbon dioxide and water so only purified air is discharged.

Key features
Our PCF® offers the following five key features:
1. High efficiency – A large-surface-area, sandwich-type cartridge boosts contact with the catalyst and improves light utilization.
2. Space saving – Fluid-dynamics-driven design makes the unit significantly more compact.
3. High performance – Uniform face velocity across each photocatalytic filter increases deodorizing performance.
4. Long life – UV LED lamps (in development) greatly extend service life.
5. Environmentally friendly – The photocatalytic filter self-regenerates under light, enabling repeated use and reducing waste.
