Total Ownership Costs: When buying an ionizer, consider the initial purchase price plus the ongoing cost of filter replacements.

Understanding 11.5 pH Water and Its Purpose

Water with a pH of 11.5 is categorized as "strong alkaline water." Unlike mildly alkaline drinking water (pH 8-9.5), this concentration is not meant for human consumption. The human body has its own robust pH regulation system, and attempting to significantly alter it by drinking such a strong substance is ineffective and potentially harmful. Instead, 11.5 pH water is primarily used for cleaning, emulsifying oils, and removing pesticide residues from fruits and vegetables. The specific applications dictate the method of production, which in turn determines the cost.

The High Cost of an 11.5 pH Water Ionizer Machine

For many who seek 11.5 pH water, the most common route is purchasing a high-end water ionizer, such as those made by the company Enagic. These devices use electrolysis to separate and ionize water into various pH levels. The initial investment for such a machine is substantial, with prices reaching well into the thousands of dollars. For example, the Enagic Kangen Leveluk K8 water ionizer can cost upwards of £2,200 or over ₹343,000, depending on the region. This price tag covers not only the initial machine but also includes the cost of ongoing maintenance, which involves filter replacements and cleaning powder.

Other high-end ionizer costs

Enagic LeveLuk SD501: Costs can exceed ₹277,000 in certain markets.
iRayer Alkaline Water Ionizer: A more moderate option, with machines potentially producing water up to pH 10.5, can still cost a few thousand dollars.

These machines represent the most significant financial commitment but offer the convenience of on-demand access to various types of ionized water.

Price of 11.5 pH Water Concentrates

For those who only need strong alkaline water for specific, periodic tasks, purchasing a concentrate is a far more economical option. These concentrates are designed to be added to regular water to increase its alkalinity. For instance, a concentrate that makes gallons of high-pH water can cost around $1.05 per 32oz of mixed solution. This eliminates the need for an expensive machine and is a budget-friendly way to produce the water when required.

Comparative Look at 11.5 pH Water Costs

To better understand the pricing landscape, here is a comparison of different methods for obtaining or creating strong alkaline water:


Method	Initial Cost	Per-Use Cost	Key Application	Considerations
High-End Ionizer Machine (e.g., Kangen)	$2,000 - $5,000+	Minimal (electricity + water) plus filter replacements	On-demand water of multiple pH levels; heavy home or business use	High upfront investment, requires maintenance, questionable health claims for drinking water
Alkaline Concentrate	$20 - $50	Approximately $1-$2 per mixed gallon	Specific cleaning tasks, stripping pesticides from produce	Inexpensive, portable, does not offer multiple water types
Bottled Strong Alkaline Water (e.g., Enagic brand for cleaning)	Varies based on volume	Varies; example found at ₹200 for 10 liters	Targeted cleaning uses	Expensive for long-term or frequent use, non-consumptive purpose
DIY using Baking Soda	Very low	Very low (cost of baking soda)	Light cleaning, creating mild alkaline water; cannot reach 11.5 pH	Unreliable pH, not strong enough for heavy-duty tasks, non-consumptive

Is the High Price Justified?

The justification of the price for 11.5 pH water depends entirely on the intended use. For consumers sold on health claims, medical experts, including those from the Mayo Clinic and Harvard Health, are skeptical. They state there is a lack of scientific evidence supporting the health benefits of drinking alkaline water and that the body effectively regulates its own pH. The high cost of expensive ionizer machines is often a point of contention for this reason. A systematic review of studies on alkaline water and cancer treatment found no rigorous evidence of a benefit.

However, for those utilizing 11.5 pH water for its proven cleaning properties, the investment can be seen differently. The ability to create a non-toxic degreaser or vegetable wash on demand may be valuable to certain households. Still, cheaper and effective alternatives exist, such as concentrates or simple baking soda solutions, depending on the need.

Conclusion: Making an Informed Decision

In conclusion, the price of 11.5 pH water varies dramatically based on how it is produced. A one-time purchase of a concentrate can be an affordable way to access the water for its specific, non-consumptive cleaning benefits. In contrast, investing in a high-end ionizer machine requires a significant initial outlay and ongoing maintenance costs. The high price tag of these machines is often questioned, especially when considering the lack of scientific support for the associated health claims regarding consumption. Ultimately, a buyer should evaluate their specific needs for strong alkaline water and choose the production method that best aligns with their budget and intended application.
