The Premigen H2 Hydrogen Water Generator delivers high-concentration dissolved hydrogen (0.8–1.2 ppm) using advanced dual-chamber electrolysis and NSF-certified internal filtration, without the need for a tank, RO system, or external equipment.
Built in Korea with medical-grade engineering standards, this compact countertop system provides clean, fresh hydrogen water for daily hydration, wellness, performance, and recovery.
What Is Hydrogen Water?
Hydrogen water is purified drinking water infused with molecular hydrogen (H₂). This antioxidant-rich form of water helps neutralise reactive oxygen species and supports clean, efficient hydration at the cellular level. Unlike alkaline ionized water, hydrogen water does not change the pH — it simply delivers filtered water enhanced with dissolved hydrogen.

Premigen H2 Key Features
➤ High hydrogen outputÂ
Delivers 800–1,200 PPB of dissolved hydrogen to support antioxidant activity and overall wellness.
➤ Powerful negative ORPÂ
Produces –400 to –800 mV ORP to help counter oxidative stress.
➤ Fast 1.5 L/min flow rateÂ
Provides fresh hydrogen water instantly.
➤ Patent-Protected Auto-Cleaning SystemÂ
Uses Hysem’s patented self-cleaning technology to flush and maintain the electrolysis chamber, keeping hydrogen performance stable (Patent No. 10-2489546).
➤ 3-Level Adjustable Hydrogen ConcentrationÂ
Allows you to choose between three hydrogen levels. Advanced PWM control keeps output steady even when flow rate changes.
➤ One-Touch OperationÂ
Simple touch controls make daily use effortless.
➤ Voice Guidance SystemÂ
Built-in voice cues guide you through hydrogen selection and basic operation.
Dual Filtration
The Premigen uses a dual-filter system that delivers 14 stages of purification before the water reaches the hydrogen electrolysis chamber. Each filter contains multiple advanced layers designed to target different contaminants, giving you cleaner, fresher-tasting water straight from your tap.
- The 1st composite filter removes sediment, rust, fine particles and reduces chlorine and chemical by-products.
- The 2nd composite hollow-fibre filter provides ultra-fine purification through UF membrane technology, activated carbon, calcium sulphite and additional non-woven layers that reduce impurities and improve taste and clarity.
Together, the two filters create a powerful multi-stage process that protects the electrolysis chamber and ensures high-quality water for hydrogen generation.
Pre-Filtration
This system includes its own dual internal filtration, so pre-filters are not required. However, optional pre-filters are available for customers in regions with higher levels of contaminants such as chlorine by-products, heavy metals, or chemical residues. These can help extend filter life and maintain consistent performance in areas with more challenging water conditions.
Our team can review your local water report and advise whether pre-filters are recommended. Please contact us for more information.
Our support team is here to help you access and review your local water report online. This assessment will identify the most suitable pre-filters to enhance your water quality and protect your ionizer.
Installation
The Premigen offers a simple, flexible setup that works with most kitchen layouts. It can connect directly to your water supply in two straightforward ways:
• Connection via a diverter valve
A diverter valve attaches to your existing kitchen tap, letting you switch between normal tap water and hydrogen water. This option requires no drilling and is the quickest way to get started.
• Connection to the cold-water feed under the sink
The unit can also be supplied directly from the cold-water line beneath the sink for a cleaner, more permanent installation. This creates a dedicated feed to the generator while keeping the countertop tidy.
Both options use standard inlet and outlet hoses, provide stable flow for consistent hydrogen levels, and require no tank, no waste line, and no complicated plumbing.
Maintenance
This system is designed for low-maintenance daily use. The internal electrodes automatically clean themselves, so there is no manual descaling or chemical cleaning required.
The only routine task is filter replacement. Each filter lasts around 4,000 litres (typically 6–12 months depending on usage). The system notifies you when replacement is needed.
Certification
This system is manufactured in Korea to international safety and quality standards and holds the following certifications:
- CE – EU/UK safety compliance for consumer use
- NSF – Certified filter materials
- ISO 13485 – Medical manufacturing quality standard
- ISO 9001 – Quality management
- ISO 14001 – Environmental standard
- RoHS – Safe material compliance
- FCC – Electronic safety and EMC compliance
These certifications confirm that the system meets recognised global safety, hygiene, and manufacturing standards for drinking water devices.
