Portable Functional Water Ionizer
Flagship Water Technology
Functional Water Ionizer is a multifunctional system designed to prepare four types of functional water in one device: alkaline, acidic, hydrogen and silver-ion water. Wide pH range: 2.5–11.2.
The system combines water electrolysis, hydrogen generation and a dedicated silver-ion electrode, allowing users to select different water functions for daily drinking, food preparation and household applications.

Why It Stands Out
01A controlled electric current passes through mineralized drinking water
02The electrodes separate the water into alkaline and acidic fractions
03Dedicated programs generate dissolved hydrogen or introduce silver ions at a selected concentration

Photocatalytic Air Purifier
A compact air purification system powered by photocatalytic technology. Light activates the catalytic surface inside the device, helping to break down airborne contaminants instead of simply capturing them.
Designed for continuous indoor air treatment, it helps reduce mold-related airborne contaminants, odors and other unwanted compounds, supporting cleaner and fresher indoor air.
The purifier connects to a mobile app for device control and monitoring, including tracking the status of the purification filters/modules and when replacement is needed.
The exterior colors can be fully customized, with private-label branding and OEM/ODM customization available for different markets and business requirements.

How It Works
01The pre-filter intercepts larger dust and protects the internal chamber
02Air passes through the catalyst-coated glass-bead element
03Ozone-free 365 nm UV-A activates the photocatalytic surface
04Surface oxidation treats adsorbed odors, VOCs and biological contaminants
Why It Stands Out
Helps reduce airborne bacteria, viruses, mold spores and related odors
Treats contaminants on the catalyst surface instead of relying only on passive capture
Long-life glass-bead catalytic element
Three operating modes: Night (quiet, lights dim automatically), Day (everyday use) and Boost (maximum power)
Touch buttons on the base for Night, Day, Boost, standby and schedule — with a 3-hour auto-off timer when no schedule is set

Two Approaches to Air Purification
Photocatalytic and HEPA + activated carbon systems use different mechanisms to address indoor air contaminants.
Criterion
Photocatalytic System
HEPA / Carbon
Primary Action
Photocatalytic oxidation and inactivation on an activated surface
Physical particle capture and odor adsorption
Odor / VOC Approach
Oxidation at the activated catalyst surface
Adsorption until carbon media becomes saturated
Particle Strategy
Pre-filter captures larger particles; photocatalysis is the primary treatment technology
High-efficiency fine-particle capture is the core strength

Hydrogen Water Bottle Pro + Hydrogen Inhalation
A multifunctional portable bottle designed to generate hydrogen-rich water for daily hydration and wellness routines.
Using electrolysis, the bottle produces dissolved molecular hydrogen (H₂) in water. Molecular hydrogen is being studied for its antioxidant potential and interaction with reactive oxygen species, which is why hydrogen-rich water is increasingly used in wellness, fitness and active-lifestyle routines.
Choose between a 3-minute quick hydrogen cycle or an 18-minute high-concentration cycle, depending on your needs. The bottle also supports hydrogen inhalation using the dedicated inhalation adapter and cannula.
A built-in mineralization system helps enrich the water with minerals and supports the preparation of alkaline water, while UV-C technology helps maintain cleanliness inside the bottle.
The device can be controlled through a smart mobile app, making it easy to manage functions and generation modes.
Designed for everyday portability, the bottle features USB-C charging and an integrated storage compartment for vitamins or supplements, making it convenient for travel, work, training and daily use.

How Photocatalytic Purification Works
Photocatalytic air purification uses light + catalyst to create an active surface that treats contaminants as air moves through the device — not just air movement, active air treatment.
01
Air Enters
A pre-filter catches larger dust and protects the purification chamber.
02
Light Activates the Catalyst
Air passes through catalyst-coated glass beads activated by ozone-free 365 nm UV-A.
03
Contaminants Are Treated
The activated surface acts on odors, VOCs and airborne biological contaminants, including bacteria, viruses and mold spores.
04
Treated Air Returns
Purified air flows back into the room.
A long-life glass-bead photocatalytic element creates an active treatment surface inside the purifier.
Designed to help reduce biological and organic airborne contaminants — bacteria, viruses, airborne mold spores, odors and VOCs.
