Zazen vs Naturopress: Alkaline Water Systems Compared

Introduction

In the quest for optimal hydration and health, many Australians are turning to alkaline water systems. The zazen alkaline water system compared to Naturopress water Ionizer represents two distinct approaches to producing alkaline water for home consumption. This article aims to provide a comprehensive comparison of these systems, exploring their technologies, benefits, and potential drawbacks.

Alkaline water, characterised by a pH level above 7 on the pH scale, has gained popularity due to its purported health benefits. While scientific evidence remains limited, some studies suggest potential advantages such as improved hydration and antioxidant properties (Fenton et al., 2018). However, it's crucial to approach these claims with caution and consider the broader context of water quality and mineral content.

The zazen Alkaline Water System and Naturopress Water Ionizer offer contrasting methods for achieving alkalinity in drinking water. Zazen employs a multi-stage filtration process aimed at mimicking nature's water cycle, while Naturopress utilises electrolysis technology to ionize and alkalize water. This comparison will delve into the specifics of each system, examining factors such as filtration effectiveness, mineral content, ease of use, and environmental impact. By exploring these aspects, we aim to provide readers with the information needed to make an informed decision about which system might best suit their needs and align with their health goals.

Here is the main body of the article comparing the zazen alkaline water system to the Naturopress water ionizer:

Understanding Alkaline Water

Definition and pH Scale

Alkaline water refers to water with a pH level above 7 on the pH scale. The pH scale ranges from 0 to 14, with 7 being neutral, below 7 acidic, and above 7 alkaline. Most tap water has a pH between 6.5 and 8.5 (World Health Organization, 2003). The zazen alkaline water system aims to produce water with a mildly alkaline pH around 7.5-8.5, while the Naturopress ionizer can create water with pH levels up to 11.2.

The relevance of water pH relates to its potential effects on the body's acid-base balance. Our blood maintains a tightly regulated pH of about 7.4. While the body has robust buffering systems to maintain this balance, some researchers hypothesize that consuming alkaline water may support these natural processes (Fenton et al., 2018).

Potential Health Benefits

Proponents of alkaline water claim various health benefits, though scientific evidence remains limited. Some potential benefits that have been studied include:

• Improved hydration: A small study found that alkaline water with a pH of 8.8 may help people stay hydrated longer compared to regular water (Heil, 2010).

• Acid reflux relief: Alkaline water with pH 8.8 was found to denature pepsin, an enzyme involved in acid reflux (Koufman & Johnston, 2012).

• Bone health: Animal studies suggest alkaline mineral water may improve bone resorption, though human studies are lacking (Wynn et al., 2009).

• Blood pressure and blood glucose: Limited evidence indicates potential benefits for blood pressure and glucose regulation in some populations (Zhu et al., 2016).

However, it's crucial to note that many of these studies are small or preliminary. More robust research is needed to confirm potential benefits and understand long-term effects. Both the zazen and Naturopress systems produce alkaline water, but through different methods that may affect mineral content and other properties beyond just pH.

Overview of Zazen Alkaline Water System

Company Background and Philosophy

Zazen Water is an Australian company founded in 2007 with a focus on providing natural, balanced water filtration systems. Their philosophy centers around mimicking nature's water cycle to produce water that is not just clean, but also mineralised and structured in a way that supports optimal hydration.

The company emphasizes a holistic approach to water treatment, considering factors beyond just contaminant removal. This includes the retention of beneficial minerals, the creation of a mildly alkaline pH, and the structuring of water molecules. Zazen's approach is rooted in the belief that water should be as close to its natural, spring-like state as possible for optimal health benefits.

Key Features of Zazen Water Filtration

The zazen Alkaline Water System employs a multi-stage filtration process that includes:

1. Ceramic pre-filter: Removes larger particles and some bacteria.
2. Activated carbon filter: Reduces chlorine, pesticides, and organic compounds.
3. Silver-impregnated ceramic filter: Provides antibacterial properties.
4. Mineral stones: Add beneficial minerals and create a mildly alkaline pH.
5. Magnetized tap: Claims to structure water molecules.

This system is designed to remove up to 99.99% of contaminants while retaining beneficial minerals. Unlike many water ionizers, the zazen system does not use electricity, relying instead on gravity and natural filtration processes.

A key feature of the zazen system is its focus on mineral balance. While many filtration systems strip water of all minerals, potentially leading to mineral deficiencies if consumed exclusively, zazen aims to provide a mineral profile similar to natural spring water. This includes calcium, magnesium, potassium, and sodium in balanced proportions (zazen Water, n.d.).

Introduction to Naturopress Water Ionizer

Company Overview and Technology

Naturopress is another Australian company specializing in water treatment systems, with a focus on water ionization technology. Founded more recently than zazen, Naturopress has quickly gained popularity in the alkaline water market.

The core technology behind Naturopress water ionizers is electrolysis. This process uses electrically charged plates to separate water into alkaline and acidic streams. The alkaline portion, with a higher pH, is used for drinking, while the acidic water can be used for cleaning or plants.

Main Features of Naturopress Ionizers

Naturopress offers several models of water ionizers, but their key features generally include:

1. Dual filtration system: Typically includes sediment and carbon filters for contaminant removal.
2. Adjustable pH levels: Users can select pH levels ranging from acidic (around pH 3) to highly alkaline (up to pH 11.2).
3. ORP (Oxidation Reduction Potential) control: Claims to produce water with antioxidant properties.
4. Multiple water settings: Options for different pH levels suited to various uses (drinking, cooking, cleaning).
5. Self-cleaning function: Periodic reversal of polarity to clean electrodes.

Unlike the zazen system, Naturopress ionizers require electricity to function and often need to be connected to the main water supply. They offer more control over the final pH of the water but may have a more significant impact on the mineral content due to the ionization process.

Comparing Zazen Alkaline Water System and Naturopress Water Ionizer

Filtration Technology

The zazen Alkaline Water System employs a 10-stage filtration process that aims to mimic nature's water cycle. This process includes:

1. Ceramic pre-filter
2. Activated carbon filter
3. Silver-impregnated ceramic filter
4. Mineral stones (including far infrared ceramics)
5. Magnetized tap

This system is designed to remove contaminants while retaining and adding beneficial minerals. According to zazen, their system can remove up to 99.99% of contaminants, including chlorine, fluoride, heavy metals, and microplastics (zazen Water, n.d.).

In contrast, the Naturopress Water Ionizer uses a dual filtration system typically consisting of:

1. Sediment filter
2. Activated carbon filter

Following filtration, the water undergoes electrolysis to produce alkaline water. While effective at removing many contaminants, the Naturopress system may not be as comprehensive in filtration as the zazen system, particularly for substances like fluoride.

A study by Koufman and Johnston (2012) found that water ionizers were effective at increasing pH but did not significantly alter the mineral content or remove contaminants beyond what was achieved by their built-in filters. This suggests that the filtration stage in ionizers plays a crucial role in contaminant removal.

Alkalinity Production

The zazen system produces mildly alkaline water through natural mineralization. The mineral stones in the system, which include coral sand and maifan stones, gradually dissolve to increase the water's pH. This process typically results in a pH range of 7.5-8.5, which zazen argues is optimal for daily consumption (zazen Water, n.d.).

Naturopress ionizers, on the other hand, use electrolysis to separate water into alkaline and acidic streams. This process allows for the production of water with a much higher pH, typically ranging from 8.0 to 11.2. Users can adjust the pH level based on their preferences or needs.

While the ability to produce highly alkaline water might seem advantageous, it's important to note that there's limited scientific evidence supporting the benefits of consuming water with very high pH levels. In fact, some studies suggest potential risks associated with long-term consumption of highly alkaline water, such as metabolic alkalosis and mineral deficiencies (Fenton et al., 2018).

Mineral Content

The mineral content of water is a crucial factor in its taste and potential health benefits. The zazen system is designed to retain and add beneficial minerals to the water. Their mineral stones release calcium, magnesium, potassium, and sodium, among other trace minerals, aiming to mimic the mineral profile of natural spring water (zazen Water, n.d.).

Naturopress ionizers, while not primarily designed for mineral addition, can affect the mineral content of water through the ionization process. Electrolysis tends to concentrate minerals in the alkaline fraction of the water. However, this process can also lead to an imbalance in mineral ratios, potentially increasing the concentration of certain minerals while reducing others (Fenton et al., 2018).

A study by Weidman et al. (2016) found that water ionization can lead to significant changes in mineral content, with increases in calcium and magnesium but decreases in trace elements like copper and zinc. This alteration in mineral balance could have implications for long-term consumption.

Installation and Ease of Use

The zazen Alkaline Water System is designed for easy countertop setup. It requires no plumbing or electrical connections, making it portable and suitable for renters or those who prefer a non-permanent solution. The system operates via gravity, with water being poured into the upper chamber and filtered into the lower chamber over time.

Naturopress Water Ionizers typically require more complex installation. They often need to be connected to the main water supply and require an electrical outlet. While this allows for on-demand alkaline water production, it also means the system is less portable and may not be suitable for all living situations.

In terms of maintenance, both systems require regular filter changes. The zazen system's filters typically need replacement every 12 months or 10,000 litres, whichever comes first. Naturopress ionizers may have varying filter lifespans depending on the model and water quality, but generally require changes every 6-12 months.

Cost Comparison

The initial cost of the zazen Alkaline Water System is generally lower than that of Naturopress ionizers. As of 2023, zazen systems range from approximately $565 to $745 AUD, depending on the model and capacity.

Naturopress ionizers, being more technologically complex, come with a higher price tag. Their models typically range from $1,250 to $2,499 AUD. However, it's important to consider long-term costs as well. Both systems require ongoing filter replacements, but the zazen system's gravity-fed operation means no electricity costs, potentially leading to lower running costs over time.

When considering cost-effectiveness, it's crucial to weigh these factors against your specific needs and preferences for water quality and alkalinity.

Health Implications of Alkaline Water

Potential Benefits of Mildly Alkaline Water

Mildly alkaline water, such as that produced by the zazen system (pH 7.5-8.5), may offer several potential health benefits:

1. Improved Hydration: A study by Heil (2010) found that alkaline water with a pH of 8.8 resulted in better hydration status compared to regular water, possibly due to reduced fluid-electrolyte loss.

2. Acid-Base Balance: While the body tightly regulates blood pH, some researchers suggest that a diet high in acid-forming foods may benefit from alkaline water consumption to support the body's buffering systems (Fenton et al., 2018).

3. Antioxidant Properties: Alkaline water, particularly when produced through ionization, may have a negative oxidation-reduction potential (ORP), theoretically providing antioxidant benefits. However, more research is needed to confirm these effects in vivo (Ignacio et al., 2013).

Concerns with Highly Alkaline Water

While mildly alkaline water is generally considered safe, there are potential risks associated with consuming highly alkaline water (pH > 8.8) over extended periods:

1. Metabolic Alkalosis: Excessive consumption of highly alkaline water could potentially lead to metabolic alkalosis, a condition characterized by elevated blood pH (Fenton et al., 2018).

2. Gastrointestinal Issues: Very high pH water may interfere with the stomach's natural acidity, potentially affecting digestion and nutrient absorption (Koufman & Johnston, 2012).

3. Mineral Imbalances: Long-term consumption of ionized alkaline water may alter mineral absorption and excretion, potentially leading to imbalances (Weidman et al., 2016).

Scientific Evidence on Alkaline Water Consumption

While some studies suggest potential benefits of alkaline water, the overall body of evidence remains limited and sometimes contradictory. A systematic review by Fenton et al. (2018) concluded that there was a lack of evidence to support the use of alkaline water for cancer treatment, osteoporosis prevention, or other health claims.

However, some promising areas of research include:

1. Acid Reflux: Koufman & Johnston (2012) found that alkaline water with pH 8.8 could denature pepsin, potentially benefiting those with acid reflux.

2. Exercise Performance: A study by Chycki et al. (2017) suggested that alkaline water consumption might enhance hydration status and acid-base balance during anaerobic exercise.

3. Blood Pressure: Zhu et al. (2016) found that drinking alkaline ionized water was associated with reduced blood pressure in elderly subjects with high-normal blood pressure.

It's important to note that many of these studies are preliminary, and more robust, long-term research is needed to confirm these potential benefits and understand any possible risks associated with long-term alkaline water consumption.

Environmental and Sustainability Considerations

Energy Consumption

The zazen Alkaline Water System operates without electricity, relying on gravity for filtration. This results in zero energy consumption during operation, making it an environmentally friendly option. The lack of electrical components also reduces the potential for electronic waste.

In contrast, Naturopress Water Ionizers require electricity to perform electrolysis and operate their digital displays. While the exact energy consumption varies by model, it's estimated that water ionizers use between 150-200 watts during operation (Alkaviva, n.d.). Over time, this energy use can contribute to increased carbon emissions, depending on the energy source.

Water Waste

Water efficiency is an important consideration, especially in water-scarce regions. The zazen system, being a gravity-fed filter, produces no waste water. All water that enters the system is filtered and available for consumption.

Naturopress ionizers, like most water ionizers, produce some waste water as part of the ionization process. The amount varies by model and settings, but typically ranges from 30-50% of the input water (Naturopress, n.d.). This acidic waste water can be used for cleaning or watering plants, but it still represents a significant amount of water that isn't available for drinking.

Longevity and Replacement Parts

The longevity of water treatment systems and the frequency of replacement part needs are important factors in their overall environmental impact. The zazen system is relatively simple, with the main replacement need being the filter cartridges. These typically need replacing annually or after 10,000 litres of use (zazen Water, n.d.).

Naturopress ionizers have more complex components, including electrodes and electronic parts. While these are designed for durability, they may require replacement or repair over time. The filters in Naturopress systems typically need replacing every 6-12 months, depending on water quality and usage (Naturopress, n.d.).

Both companies offer recycling programs for their filters, which helps to mitigate the environmental impact of these replaceable components. However, the more complex nature of the Naturopress ionizers may lead to more electronic waste over the long term.
