A water purifier using RO (Reverse Osmosis) filtration technology, after passing water through the RO membrane, renders the water pure but devoid of minerals. This makes it ineffective for electrolysis, as the essential minerals required for the process are no longer present. Consequently, the alkaline water produced by such machines primarily relies on the additional filter cartridges rather than the electrolysis process.
Therefore, a water purifier using RO technology advertised with an electrolysis unit does not qualify as a “standard” alkaline ionized water purifier. A “standard” alkaline ionized water purifier must be equipped with a specialized electrolysis control unit (microchip) that can generate multiple levels of both acidic and alkaline ionized water, offering a wide pH range from low to high. Ideally, a high-quality machine should achieve a minimum pH range of 4.5 to 10.0, with devices featuring multiple electrode plates capable of even broader ranges. Additionally, it should ensure stability and consistent performance throughout water usage.

RO water filters that create alkaline water through a mineral replacement core work by adjusting the pH using the materials in the core. As a result, the maximum pH level typically reaches only up to 9.5 and will gradually decrease as more water is used over time. The minerals in the water are limited in variety and their concentrations are relatively low. On the other hand, the alkaline water produced by a proper ionized alkaline water filter is superior because it is created from water with natural minerals, and undergoes electrolysis. This process allows the water to maintain stable alkalinity, strong antioxidant properties, and be rich in trace minerals. Additionally, the water molecules are broken into smaller clusters, allowing them to penetrate cells quickly, effectively hydrate, and quench thirst more efficiently than alkaline water produced by a mineral core filter.

A proper ionized alkaline water machine should be equipped with a minimum of 5 electrodes in its electrolysis unit. For machines with only 3 electrodes, the electrodes should be larger in size, with a flat, full surface to ensure maximum contact area during the electrolysis process, resulting in higher efficiency. The electrodes should be made from titanium coated with platinum and be of high quality, typically manufactured in South Korea or Japan. These materials ensure stability and durability, though the cost is significantly higher than electrodes of unknown origin.
When purchasing, customers should ask the seller to provide actual images of the electrolysis unit, the electrodes, and documentation to verify the origin and authenticity of the electrolysis unit to avoid buying substandard or counterfeit products.

For a proper ionized alkaline water machine, a solid flat plate electrode is considered better than a mesh electrode because it offers a larger electrolysis surface area, reduces the buildup of residues, and is easier to clean. This results in better electrolysis efficiency and longer lifespan compared to mesh electrodes, which have smaller surface areas, are more prone to residue buildup, and are harder to clean.

A proper ionized alkaline water machine should be capable of producing at least 3 basic types of electrolysis water: Acidic, Neutral, and Alkaline. A high-quality machine will typically generate 7 or more types of water, with pH levels ranging from 3.0 to 11.0, depending on the model and brand. To ensure that the machine is "properly standard," the acidic water should have a pH of 4.5 or lower, while the alkaline water should reach a pH of 10.0 or higher. Many machines produce alkaline water with a pH of only 9.5, and do not create sufficiently low-acidic water due to limitations in their electrolysis technology or electrode quality.

Top global manufacturers of ionized alkaline water machines have been using UF (Ultrafiltration) or Nano filtration technologies for decades, with UF filtration being the most popular. UF filtration removes harmful contaminants while retaining the natural minerals in water, ensuring that electrolysis remains stable and effective over time. This technology guarantees the water is clean and meets drinking water standards. In contrast, RO filtration (Reverse Osmosis) removes all minerals, leaving "pure water," which would not support proper electrolysis and could lead to unstable and poor-quality ionized water.

The electrolysis unit is considered the "heart" of a proper ionizer machine. The quality and size of the electrodes are crucial for effective electrolysis. Electrodes come into direct contact with water during electrolysis, and over time, they can corrode. To prevent this, the electrodes should be made of inert, precious metals like titanium, coated with platinum to resist corrosion and ensure the safety and quality of the ionized water throughout the machine's lifespan.
A larger electrode surface area provides better electrolysis efficiency. More electrodes in a machine generally lead to better electrolysis results, resulting in higher pH, hydrogen concentration, oxidation-reduction potential (ORP), and minerals in the water compared to machines with fewer electrodes. Additionally, more electrodes help the machine maintain optimal performance, even with higher water flow rates.

To choose the right alkaline ionized water filter and avoid mistakes, you should consider the following 5 GOLDEN CRITERIA:
- Technology: The filter should meet 3 core standards: Electrolysis System, Microcontroller, and Filtration System. Be sure to ask the seller for detailed information about the origin and source of these technologies and their compatibility with the product.
- Water Quality: The machine must be capable of producing water with a wide range of pH values, including: Acidic water with pH ≤ 4.5 Alkaline water with pH ≥ 10.0 The water must remain stable 24/7.
- Machine Quality: The product must have prestigious national and international certifications and unique achievements recognized by trusted organizations.
- Origin: The product must have a clear, transparent origin with all the necessary information, images, and documentation.
- Cost and Service: The price should reflect the true value and quality of the product. The company should offer quick warranty services and affordable replacement parts.

There are several ways to check the pH of ionized water:
* pH Meter: Use a pH meter by placing its probe into the water sample. The digital screen will display the result. However, the pH can vary depending on the water source, temperature, accuracy of the meter, and the person conducting the test.
* pH Indicator Solution: Use a pH indicator solution which changes color based on the pH level. This is a common method.
* pH Test Strips: Use pH test strips (similar to litmus paper). When dipped in water, the strip will change color according to the water's pH within a 0.5 unit range.

- In surveys, most users prefer one faucet for both types of water to avoid confusion when selecting water. To increase safety: Alkaline ionized water filters are designed with a single faucet, where users can select the water type (acidic or alkaline) via a control panel.
- Safety features include an LCD screen and audible alerts when selecting the water type. Additionally, the machine can issue a verbal warning about water types that should not be consumed.
- The self-cleaning electrolysis system (designed by ROBOT) automatically cleans the system after every use without using chemical cleaners. This cleaning takes 20-30 seconds to ensure no cross-contamination between water types.

- The electric faucet has the advantage of being able to provide multiple types of water (pure, alkaline ionized, low acid, etc.) from a single faucet through a control system when we take water.
- Due to the construction of the electric faucet, with an internal valve for turning the water on and off, there will be a slight delay as water flows through the faucet. The water in the pipe will drip a few drops before stopping completely due to the inertia of the water flow, causing a 1-2 second delay before turning off. This is normal and necessary due to the design. Therefore, the manufacturer adds a tray to collect excess water, depending on the faucet and machine design.
When taking water, users should hold the glass a little longer to collect these last few drops.
In contrast, mechanical faucets only dispense one type of water, and the on/off mechanism is located at the faucet’s mouth, so there is no water in the pipe to create inertia or cause the drips delay seen in electric faucets.
- For an electrolysis water filter, you must use an electric faucet. After each use, the remaining water in the faucet should be drained so that the water source used in the next collection does not mix with the previous type of water, ensuring the water has the correct pH level.

A good alkaline ionized water filter should meet the following criteria:
- Authentic Products: Manufactured by reputable, top-tier brands.
- Electrodes: Made from titanium coated with platinum (Platinum).
- Water Kinds: The machine should be able to produce 5-9 different types of water, with a pH range from acidic to alkaline. The dissolved hydrogen content should also be high.
- Filter & Pre-treatment System: The filter should be complete and suitable for the water source in Vietnam.
- Warranty & Price: The warranty period and price should align with customer needs.

To ensure the best absorption and effect of medication, it is recommended to use neutral water (pH 7.0) from the alkaline ionized water filter when taking medication. You may continue drinking alkaline water, but it should be 2 hours after taking medication to ensure proper absorption and effectiveness.

- Children under 3 years old: They should only drink purified water, not alkaline ionized water.
- Children aged 4-12: They should drink alkaline water at level 1 or level 2, avoiding level 3.
- Elderly individuals may start with a small amount (around 230ml of level 1 alkaline water per day) to help detoxify the body and eliminate heavy metals and accumulated pharmaceutical residues over time.

For beginners, it’s recommended to start by drinking from level 1, with 1-3 glasses of water each day during the first week. You can gradually increase the amount of water daily to help your body adjust.
If there are no adverse effects on the body during the first week, increase to level 2. At level 2, drink 1-3 glasses of water per day for the first week and then adjust the daily intake as needed.
On average, it’s recommended to drink alkaline ionized water for about two to three weeks at each alkaline level.

On average, antioxidant properties (hydroxyl ions) last between 18-24 hours. Water with higher pH (alkaline water) can last around 1-2 weeks. Smaller water molecule clusters can last between 1-3 months.

The incoming water, after passing through the filter system, will have impurities, colors, odors, and harmful bacteria and viruses removed, while retaining beneficial natural minerals through UF technology.
The water then flows into the electrolysis chamber where the electrolysis process takes place. The electrodes separate and regenerate the water into smaller molecules that flow towards the anode and cathode plates. Here, a reaction occurs, producing H+ (acidic) and OH- (alkaline) ions.
A membrane separates the ions, so after the process is completed, acidic water is retained at the positive terminal, and alkaline water is at the negative terminal. The water flows out through the faucet for use. Meanwhile, the electronic control system helps manage the electrolysis to produce the desired pH levels for use.

If the water becomes warm when coming out of the machine, this is not a fault and does not affect the machine's operation or water quality.
The warmth may be due to room temperature or heat generated inside the machine from the UV sterilization system or electrolysis chamber.

If a filter cartridge is leaking water, you should Disconnect the machine from its power supply and Turn off the water supply valve to the machine.
nspect the location of the leak and resolve the issue. Most leaks come from components not being installed correctly. Reconnect the pipes and filter by pressing the pipe firmly into the quick-connect fitting and pulling to ensure it's secure. You can shorten the pipe or replace it if needed to eliminate the leak. Alternatively, contact the customer service department for detailed assistance on how to fix the issue.
