Core Technology Stack

UVC Optical Cavity Enhancement

The optical cavity structure is designed to improve the utilisation of UVC light within the reaction space, supporting more efficient delivery of ultraviolet energy in a compact system.

TiO₂ Photocatalytic Technology

The TiO₂ nano-sol photocatalytic layer is used to support the treatment of selected microorganisms, volatile organic compounds and odour-related pollutants within the purification process.

Silver-Ion High-Efficiency Filtration

The silver-ion high-efficiency filter is designed to capture fine particles while providing antibacterial support within the filtration system.

Advanced 6-Stage Air Purification System

Pre-Filter

Captures large dust, hair, and pet dander – extends filter life.

Active Carbon Filter

Adsorbs odors, smoke, VOCs, and harmful gases.

Silver Ion Coating

Antibacterial protection – inhibits mold and bacteria growth.

True HEPA Filter

Removes 99.97% of PM2.5, allergens, fine dust, and airborne particles down to 0.3 microns.

UV + TiO₂ Purification

Destroys VOCs, odors, bacteria, and viruses at molecular level.

UVC Disinfection

Powerful germicidal UV light kills remaining bacteria and viruses in the air stream.

Long-Lasting Enhanced Silver Ion Coating

✓ Long-lasting protection: Maintains antibacterial and antiviral effectiveness for over one year with a single application. Forms a reliable, uniform coating that remains effective over time without degradation. ✓ No risk of resistance: Does not contribute to drug-resistant superbugs, unlike some chemical disinfectants. ✓ Safe and eco-friendly: Water-based, non-toxic, non-flammable, and harmless to humans and the environment.

Broad-Spectrum Enhanced Photocatalysis

✓ Enhanced efficiency: Extends the absorption spectrum to 400–500 nm, enabling activation under both UV and visible light. ✓ Applicable to HEPA filter: Nano sol enables coating on HEPA without pore blockage, unlike typical TiO₂-polymer mixtures. ✓ Natural plant extracts: Contain abundant laccase, hemicellulase, and glucose oxidase, which can effectively absorb and capture odor molecules and quickly decompose them into harmless substances.

Optical Cavity Enhanced UVC Disinfection

✓ Effective Pathogen Killer: UVC radiation inactivates bacteria and viruses by disrupting their genetic material. ✓ Light Enhancer: Employs our patented light enhancer, combining high-reflectivity materials with advanced topological design to recycle light within the air duct and increase UVC energy by 3–5 times. ✓ Energy Saving: 40–60% optical power consumption saving.
