Alkaline water has gained popularity in recent years for its potential health benefits. Two prominent options 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 right for your needs.
Overview of Alkaline Water
Before diving into the specifics of each machine, it's important to understand what alkaline water is and why people are interested in it. Alkaline water has a higher pH level than regular drinking water. While normal tap water generally has a pH of 7 (neutral), alkaline water typically has a pH of 8 or 9.
Proponents of alkaline water claim it can:
- Neutralize acid in the bloodstream
- Boost metabolism and help with weight loss
- Slow the aging process
- Prevent chronic diseases like cancer
However, it's important to note that scientific evidence supporting these claims is limited, and more research is needed to conclusively prove the health benefits of alkaline water[3].

Performance and Water Quality
Both the Kangen K8 and the Naturopress Alkaline Water Ionizer are capable of producing high-quality alkaline water. They both use platinum-coated titanium plates for electrolysis, which is considered the industry standard for durability and performance.
The Kangen K8 has a slightly wider pH range (2.5 - 11.5) compared to the Naturopress (3.0 - 11.2), but this difference is unlikely to be significant for most users. The Naturopress actually boasts a higher maximum negative ORP (-800 mV vs -722 mV for the Kangen), which could potentially indicate stronger antioxidant properties in the water it produces.
One area where the Naturopress stands out is its dual filtration system. This is likely to be more effective at removing contaminants from the water compared to the single filter system in the Kangen machine. The Naturopress filter also has a longer life (up to 9,000 L compared to 5,500 L for the Kangen), which means less frequent replacements and potentially lower ongoing costs.
Ease of Use and Maintenance
Both machines are designed to be user-friendly, but they approach this in different ways. The Kangen K8 features a large, full-color LCD panel and voice prompts in 8 languages, which can be helpful for users who prefer auditory instructions or households where multiple languages are spoken.
The Naturopress, while not specifying language options, does feature a self-cleaning function. Both machines have some form of automatic cleaning, which is crucial for maintaining the electrodes and ensuring consistent performance over time.
The external mineral port on the Naturopress is a nice feature that allows users to easily add minerals to their water if desired. This isn't available on the Kangen K8.
Cost Considerations
Perhaps the most significant difference between these two machines is the price. The Kangen K8 is priced at around $4,980, while the Naturopress ranges from $1,250 to $2500. This makes the Naturopress about a third of the cost of the Kangen machine.
It's important to note that the high cost of Kangen machines is partly due to their multi-level marketing business model, which adds significant overhead to the price. The Naturopress, being sold directly to consumers, can offer similar features at a much lower price point.
When considering long-term costs, the longer filter life of the Naturopress (9,000 L vs 5,500 L for the Kangen) could lead to additional savings over time.
Warranty and Support
The Kangen K8 comes with a 5-year warranty, which is somewhat short considering its high price point. The Naturopress offers an extended warranty option, though the exact terms aren't specified in the available information.
Both companies seem to offer good customer support, but Enagic (the maker of Kangen machines) has a longer track record in the industry. However, this doesn't necessarily translate to better support, and many users report positive experiences with Naturopress customer service.
Environmental Considerations
Both machines are designed to reduce reliance on bottled water, which can have significant environmental benefits. By producing alkaline water at home, users can dramatically reduce plastic waste associated with bottled water consumption.
The longer filter life of the Naturopress could be seen as a slight environmental advantage, as it means less frequent filter replacements and thus less waste. However, both machines are generally considered environmentally friendly alternatives to bottled alkaline water.
Which Machine is Right for You?
Choosing between the Kangen K8 and the Naturopress Alkaline Water Ionizer ultimately comes down to your specific needs, preferences, and budget.
The Kangen K8 might be preferable if:
- You want a machine from a well-established brand with a long history in the market
- You need multilingual voice prompts
- You're comfortable with the higher price point
The Naturopress Alkaline Water Ionizer might be a better choice if:
- You're looking for a more budget-friendly option
- You prefer a dual filtration system
- You want a machine with a longer filter life
- You'd like the option of an external mineral port
