Technology Overview

Our photocatalytic formaldehyde removal service utilises advanced nano titanium dioxide (TiO₂) photocatalyst technology, professionally applied to interior surfaces — including walls, ceilings, furniture and fixtures — to form an ultra-thin, invisible catalytic layer. Activated by ordinary visible light, the coating continuously breaks down both airborne and surface-borne harmful pollutants such as formaldehyde, benzene, TVOCs and other volatile organic compounds, converting them entirely into harmless carbon dioxide and water.

Unlike adsorption-based air treatment products that become saturated and lose efficacy over time, the photocatalytic layer itself is not consumed during the reaction, delivering sustained, long-term purification performance. The water-based formulation is non-toxic, non-corrosive and fully compliant with EU and Hong Kong safety standards, with no secondary pollution generated throughout the treatment process.

Key Benefits

Source-Level Pollutant Decomposition 

Rather than masking odours or trapping pollutants temporarily, the photocatalytic reaction breaks down formaldehyde, benzene, TVOCs and other indoor contaminants at the molecular level, addressing poor indoor air quality at its root cause.

Continuous, Long-Lasting Protection 

The catalytic coating remains permanently active after a single application, with no depletion or replacement of consumables required. It provides round-the-clock air purification for years after treatment, delivering sustained value with minimal ongoing maintenance.

Safe, Eco-Friendly Formulation 

The water-based nano TiO₂ formula is non-toxic, non-irritating and non-corrosive to most interior materials. It produces no harmful by-products or secondary pollution, and meets strict EU and Hong Kong environmental and safety benchmarks, making it suitable for sensitive environments including homes with children and pets.

Broad Surface & Scene Compatibility 

Suitable for application on walls, wallpaper, wooden furniture, fabrics, leather, ceilings and most common interior materials. The service is ideal for newly completed residential properties, commercial office buildings, schools, healthcare facilities, hospitality venues and retail spaces.

Comprehensive Air Quality Improvement 

Beyond formaldehyde and VOC removal, the photocatalytic treatment also inhibits the growth of bacteria, mould and mildew, while neutralising persistent everyday odours such as cooking fumes and pet smells, to deliver all-round improvement to indoor air quality.
