Alkaline water has gained popularity in recent years due to its potential health benefits. Two prominent brands in this space are the Kangen Water Machine and the Naturopress Alkaline Water Ionizer. This article will provide an in-depth comparison of these two systems to help you make an informed decision about which might be best for your needs.
Overview of Alkaline Water Ionizers
Alkaline water ionizers are devices that use electrolysis to separate water into alkaline and acidic components. The alkaline water produced is believed to have various health benefits, including improved hydration, antioxidant properties, and potential acid-reflux relief. These machines typically allow users to adjust the pH level of the water and often include filtration systems to remove contaminants.
Kangen Water Machine
Kangen Water Machines are produced by Enagic, a Japanese company that has been in business for several decades. These devices are known for their high quality and have gained a significant following worldwide.
Naturopress Alkaline Water Ionizer
Naturopress is an Australian company that offers a range of health and wellness products, including their Alkaline Water Ionizer. This machine aims to provide similar benefits to the Kangen system at a more affordable price point.

Detailed Comparison
Price
One of the most significant differences between these two systems is the price. The Kangen K8 Water Machine is priced at $4,980, while the Naturopress Alkaline Water Ionizer ranges from $1,250 to $2,500. This makes the Naturopress a more budget-friendly option for those interested in alkaline water but hesitant about the high cost of the Kangen system.
Technology and Performance
Both machines use similar technology, featuring 8 platinum-coated titanium plates for electrolysis. This suggests that their basic functionality and performance should be comparable.
The pH range is slightly broader in the Kangen K8 (2.5 - 11.5) compared to the Naturopress (2.5 - 11.2), but this small difference is unlikely to have a significant impact for most users. Both machines can produce water with a high negative ORP (Oxidation Reduction Potential) of up to -800 mV, indicating strong antioxidant properties.
Water Types and Versatility
The Kangen K8 produces 5 types of water: Strong Kangen, Kangen, Neutral, Beauty, and Strong Acidic. Each type is designed for specific uses, from drinking to cleaning.
The Naturopress Alkaline Water Ionizer offers 6 settings for both acidic and alkaline waters, potentially providing more versatility in water types. However, specific details about these settings are not provided in the available information.
Filtration System
The Naturopress Alkaline Water Ionizer appears to have an advantage in terms of filtration. It features a dual filter system with 4 stages (PP cotton, KDF, Active carbon, fiber carbon), which may provide more thorough filtration compared to the single filter system in the Kangen machine.
Additionally, the filter life of the Naturopress is significantly longer at 9,000 liters (1-2 years) compared to the Kangen's 3,000 liters (approximately 6 months). This could result in lower maintenance costs and less frequent filter changes for Naturopress users.
Self-Cleaning and Maintenance
Both machines feature self-cleaning functions, which is crucial for maintaining the performance and longevity of the system. The Naturopress boasts an automatic self-cleaning function, while the Kangen K8 requires periodic cleaning. The automatic feature of the Naturopress could be more convenient for users who prefer a low-maintenance option.
Display and User Interface
The Kangen K8 features a full-color LCD touchscreen display, which may provide a more modern and user-friendly interface. It also supports 8 languages, making it accessible to a wide range of users globally.
The Naturopress has an LCD screen, but specific details about its interface and language support are not provided in the available information.
Warranty and Support
The Kangen K8 comes with a 5-year warranty. Naturopress offers an extended warranty, though the exact duration is not specified in the available information. It's worth noting that Enagic, the maker of Kangen machines, has been in business longer and may have a more established support network.
Worldwide Use and Shipping
Both machines are designed for worldwide use, with the ability to handle different voltages. This is particularly useful for international travelers or those who may move to different countries.
Importantly, Naturopress offers worldwide shipping, making their product accessible to a global market. Kangen machines are typically sold through distributors, which may limit availability in some regions.

User Experience and Reviews
While specific user reviews for these exact models are limited, general feedback for both brands tends to be positive.
Kangen users often praise the quality of the water and the durability of the machines. Many report feeling health benefits, though it's important to note that individual experiences can vary and many health claims are not scientifically proven. Some users do mention the high cost as a significant drawback.
Naturopress users generally appreciate the more affordable price point while still reporting satisfaction with the water quality. The longer filter life is often cited as a positive feature. Some users have reported noticeable improvements in hydration and overall wellbeing, though again, individual experiences may vary.
Environmental Considerations
Both systems can help reduce reliance on bottled water, which is a positive environmental impact. The longer filter life of the Naturopress could potentially result in less waste from filter replacements.
Installation and Setup
Both machines are designed for home use and can typically be installed without professional help. They usually connect to the kitchen faucet, though under-sink installations may be possible with additional equipment.
The Naturopress website mentions that their machine is "fast to install," which could be an advantage for those who want a quick setup process.
Ongoing Costs
While the initial purchase price is an important consideration, it's also worth thinking about ongoing costs. The main recurring expense for both machines will be filter replacements.
Given the longer filter life of the Naturopress (9,000 liters vs 3,000 liters for the Kangen), it's likely that the ongoing costs would be lower for the Naturopress system. However, the exact costs would depend on the price of replacement filters and how much water is produced.
Scientific Evidence
It's important to note that while many users report health benefits from alkaline water, the scientific evidence for these claims is mixed. Some studies have shown potential benefits, particularly for acid reflux, but more research is needed to conclusively prove many of the health claims associated with alkaline water.
Both the Kangen and Naturopress machines produce water with similar pH and ORP ranges, so any potential benefits should be comparable between the two systems.
Conclusion
Both the Kangen Water Machine (K8) and the Naturopress Alkaline Water Ionizer are capable of producing alkaline water with high negative ORP values. They use similar technology and offer comparable pH ranges.
The most significant difference between the two is the price, with the Naturopress being considerably more affordable. The Naturopress also offers some potential advantages in terms of filtration, with a dual filter system and longer filter life.
The Kangen machine, while more expensive, comes from a well-established brand and features a more advanced user interface. It may be preferred by those who prioritize brand reputation and are willing to pay a premium price.
For those interested in trying alkaline water without making a large financial commitment, the Naturopress could be an excellent option. Its worldwide shipping also makes it accessible to a global market.
Ultimately, the choice between these two systems will depend on individual priorities, budget, and specific needs. Both appear to be capable of producing high-quality alkaline water, and either could be a good choice for those interested in exploring the potential benefits of alkaline water.
Remember, while many users report positive experiences with alkaline water, it's always advisable to consult with a healthcare professional before making significant changes to your diet or health routine.
