Domestic Purification Water System D4H
The tap water in the municipal city is the water source of our machine. Firstly, filtering tap water through four filters and absorbing and other processions and then decomposing by Electrolysis Chamber, due to the influence of hydrogen bond, the ordinary tap water is composed of 13 to 15 small molecular clusters, when the water enter into the electrolysis chamber, the hydrogen bond of water molecule is opened with the influence of electric field and produces the small molecular cluster water with 5 to 6 water molecules. At the same time, the positive ions such as Ca2+, Mg2+, K+, H+ and so on in solution move toward the negative pole with the influence of electric field. According to the strength of electro negativity ‘capability, H ion has a reduction then the electro negativity becomes hydrogen. Due to the fact that the density of H ion decreases, the hydroxide root ion is thicker and then water become weak alkaline with the PH up to 7, the water produced in this pole is alkaline water. At the time, in the positive pole some of negative ions such as Cl-, SO42-, NO3-, NO2-, OH- etc. move to positive pole. Among plenty of negative ions, the hydroxide root ion loses electrodes easterly and then has an oxidative reaction and produce oxygen and water with the loss of electrodes. At the same, the density of H ions rises because density of the hydroxide root ion decreases so the water becomes weak acid with PH down to 7 so the water produced is acid ionic water. The chemistry formulas in two poles are as follows:
In negative pole: 2H2O+2e=2OH-+H2
In positive pole: 2H2O-4e=4H++O2

Advanced Home Water Purification with the Domestic Purification Water System D4H
Ensure clean, safe, and great-tasting drinking water for your household with the Domestic Purification Water System D4H—a compact, multi-stage filtration unit engineered for residential use. Combining sediment filtration, activated carbon, and advanced reverse osmosis (RO) technologies, the D4H effectively removes chlorine, heavy metals (lead, arsenic, mercury), fluoride, nitrates, microbes, and dissolved solids—delivering water that meets or exceeds EPA and WHO drinking water standards.
Engineered for Performance, Convenience, and Everyday Reliability
The D4H Domestic Purification Water System features a 4-stage purification process:
5-micron PP Sediment Filter – Removes rust, sand, and suspended particles.
Granular Activated Carbon (GAC) – Reduces chlorine, VOCs, and organic contaminants.
Carbon Block Filter – Polishes taste and odor; captures fine particulates.
High-Rejection Thin-Film Composite (TFC) RO Membrane – Removes up to 99% of TDS, heavy metals, bacteria, and viruses.
An optional mineral re-mineralization stage (available on select models) restores beneficial calcium and magnesium for balanced pH and improved taste.
- Purification Capacity: Up to 50 GPD (190 L/day) – Ideal for families of 4–6.
- Reduces TDS by >95% – Effective against lead, arsenic, fluoride, nitrates, and microplastics.
- Compact Under-Sink Design – Saves counter space; includes dedicated faucet.
- Automatic Flushing & Leak Protection – Extends membrane life and prevents water damage.
- Easy Filter Replacement – Tool-free cartridge changes every 6–12 months.
- NSF/ANSI Certified Components – Meets standards 42, 53, 58, and 401 for contaminant reduction.
Trusted for Healthy, Great-Tasting Water at Home
From reducing hard water scaling in kettles to eliminating metallic aftertastes and protecting children from lead exposure, the D4H delivers peace of mind with every glass. Its efficient design minimizes wastewater (1:1 drain ratio on newer models), and the included TDS monitor allows real-time water quality verification.
Whether you’re on municipal or well water, the Domestic Purification Water System D4H transforms your tap into a source of pure, safe, and refreshing drinking water—right from your kitchen.
Pure water. Peace of mind. Every day.
