Origins and Purification Process
To understand the fundamental differences between Dasani and Smartwater, you must first look at how each is created. While both are purified bottled waters owned by Coca-Cola, their processes diverge significantly, affecting the final product.
How Dasani is Purified
Dasani water begins as treated municipal tap water. It undergoes a rigorous purification process that involves a multi-barrier system, which includes reverse osmosis and nanofiltration, to strip it of impurities. Once purified, the demineralized water is then enhanced with a unique blend of minerals, including magnesium sulfate, potassium chloride, and salt, to create a consistent, distinctive taste. This re-mineralization step is designed to give Dasani its flavor, regardless of its original municipal source.
How Smartwater is Purified
Smartwater is created through a process of vapor distillation, which is a modern take on the natural water cycle. The water is boiled into a vapor, which leaves behind most impurities, and then condensed back into liquid form. After this step, electrolytes are added back for flavor. These added electrolytes typically include calcium chloride, magnesium chloride, and potassium bicarbonate. Smartwater is then treated with ozonation, where ozone gas is bubbled through the water for final disinfection before bottling.
Taste Profile
Taste is highly subjective, but consumer feedback and taste tests offer some general insights into the distinct flavor profiles of Dasani and Smartwater.
- Dasani: Many describe Dasani's taste as slightly mineral or even somewhat metallic, often noting a sour or puckering sensation with a rougher finish. This flavor comes from the specific mineral blend added back into the water after purification.
- Smartwater: Smartwater is often characterized as clean and crisp, though some taste testers have noted a distinct flavor from the distillation process. For some, this flavor is described as complex, but in a less pleasant way, with a bitter or dry finish.
Health and Ingredient Considerations
While both are ultimately hydration sources, the additives and processing methods of Dasani and Smartwater can present subtle health differences for consumers.
- Dasani: The pH level of Dasani is typically around 5.6, making it slightly acidic. The minerals added, such as magnesium sulfate and potassium chloride, are safe in the trace amounts used, but some critics argue the added sodium might increase thirst. Like many bottled waters, Dasani has also faced scrutiny over microplastic contamination.
- Smartwater: Smartwater offers a standard purified water and a specific 'alkaline with antioxidant' version, which has a pH of 9.5+. For some, this might be a selling point, though health experts note limited research on the benefits of alkaline water. Critics have also questioned whether the expensive, extra distillation step is nutritionally beneficial, since minerals are just added back in anyway.
Comparison Table
| Feature | Dasani | Smartwater |
|---|---|---|
| Source Water | Municipal tap water | Municipal tap water or British spring water (depending on location) |
| Purification Method | Multi-barrier filtration, reverse osmosis, and nanofiltration | Vapor distillation |
| Added Minerals (Electrolytes) | Magnesium sulfate, potassium chloride, and salt | Calcium chloride, magnesium chloride, potassium bicarbonate |
| Standard pH Level | Approximately 5.6 (slightly acidic) | Approximately 6.5 (mildly acidic), but varies |
| Alkaline Version Available? | No | Yes (Smartwater alkaline with 9.5+ pH) |
| Taste Profile | Often described as mineral, sometimes metallic or sour | Often described as crisp, though some note a distinct distilled flavor |
| Price | Generally lower cost | Higher cost due to specialized process and marketing |
| Bottle Type | Primarily standard PET plastic | Primarily PET plastic, also available in 100% recycled plastic bottles in some regions |
Making Your Choice
Ultimately, the choice between Dasani and Smartwater comes down to personal preference for taste, health priorities, and budget. For those seeking basic, consistent, and affordable hydration, Dasani is a perfectly fine option, assuming you don't mind its characteristic taste. For people who prioritize the crispness associated with vapor distillation and don't mind paying a premium, Smartwater is a viable alternative. Those with an interest in alkaline water also have a clear path to Smartwater's specialized product. However, both are essentially filtered and re-mineralized water, and neither offers significant health advantages over standard tap water in most regions, which is both cheaper and more environmentally friendly.
Environmental Impact
Both Dasani and Smartwater contribute to single-use plastic waste, a significant environmental problem. The production processes for bottled water consume substantial energy, and the transportation adds to carbon emissions. Consumers concerned about their environmental footprint may want to consider using reusable water bottles filled with filtered tap water. Both brands have taken some steps to address this, with Smartwater offering some bottles made from 100% recycled PET plastic, but the overall reliance on plastic remains a concern.

Conclusion
So, is Dasani or Smartwater better? There is no single answer. Dasani is a budget-friendly, mass-market purified water with a distinct mineral-enhanced taste. Smartwater is a premium, vapor-distilled water with a different mineral blend and a cleaner, albeit sometimes criticized, taste profile. Both are products of Coca-Cola and utilize marketing to differentiate themselves from each other and from tap water. When making your choice, consider your personal taste, budget, and environmental impact. For basic hydration, tap water is often the best, most sustainable option, but when purchasing bottled water, the decision rests on which brand's specific characteristics you prefer.
