PCO Technology
Photocatalytic Oxidation (PCO) is an advanced air treatment technology that uses UV-C light and TiO₂ catalyst surfaces to help reduce odors, VOCs, bacteria, and airborne pollutants in indoor environments.
UV-C + TiO₂ working together
PCO is not just a filter. It is a reaction process. When UV light activates a TiO₂-coated surface, it creates highly reactive compounds that help break down odor molecules and volatile organic compounds in the air.
Air enters
Contaminated air carrying odors, VOCs, and particles moves into the treatment chamber.
UV-C activates TiO₂
UV-C light shines onto the titanium dioxide coated surface inside the PCO module.
Oxidation begins
Reactive compounds are formed and help break down odor molecules and pollutants.
Cleaner air exits
The treated air passes through filtration and returns fresher to the space.
Designed for continuous odor and air treatment
Odor reduction
Helps reduce everyday odors from kitchens, pets, humidity, waste areas, and closed spaces.
Airborne pollutant control
Supports reduction of VOCs and some airborne contaminants when designed with proper airflow.
Works with carbon filtration
PCO works best when combined with activated carbon and pre-filtration for stronger odor control.
Suitable for daily use
Unlike ozone shock treatment, PCO-based systems are designed for continuous air treatment.
PCO vs. ozone shock treatment
PCO for homes, yachts, restaurants, pet facilities and commercial spaces
PCO technology is useful for spaces that need continuous air treatment, especially where odors, VOCs, humidity-related smells, and indoor air quality issues are a daily concern.
