Distilled, Spring, and Purified Water: What’s the Real Difference?
Learn about the sources, benefits, health impacts, and taste differences of distilled, spring, and purified water.
With an ever-increasing selection of bottled waters on the market, understanding what sets distilled water, spring water, and purified water apart is essential for making informed choices about what you drink. Each type has a unique origin, purification method, mineral content, taste profile, and potential health impact. This article offers a comprehensive comparison designed to clarify which water might best suit your needs, highlighting core differences, regulations, and frequently asked questions.
Table of Water Types
| Type | Source | Purification | Mineral Content | Taste | Main Use |
|---|---|---|---|---|---|
| Distilled Water | Any (tap, well, spring) | Distillation (boiling, condensing) | Almost none | Flat, neutral | Medical, appliances |
| Spring Water | Underground springs/aquifers | Natural filtration, minimal processing | Moderate (calcium, magnesium, potassium, etc.) | Crisp, mineral-flavored | Drinking, beverage production |
| Purified Water | Any (often tap) | Reverse osmosis, distillation, or filtration | Low to none (can be re-added) | Neutral, clean | Drinking, lab, household use |
Spring Water: Nature’s Refreshment
Spring water is sourced directly from underground springs or aquifers. This means the water travels through layers of rock and soil, picking up minerals naturally before emerging at the surface. Natural filtration occurs during this journey, but bottlers typically apply minimal processing—just enough to remove harmful contaminants while preserving the mineral content that makes spring water unique.
Spring water is renowned for its mineral composition, commonly containing calcium, magnesium, and potassium. These minerals not only affect taste but also contribute to perceived health benefits. The flavor of spring water can range from crisp to mildly sweet, depending on the originating locale and its geological makeup.
Regulatory standards stipulate that to be labeled as spring water, bottlers must ensure the product comes from a protected underground source, is bottled at source, and is free of bacteria and pollutants.
Key attributes of spring water include:
- Origin: Deep underground aquifers and springs
- Mineral Retention: Calcium, magnesium, potassium, and trace minerals
- Taste: Distinct, crisp, sometimes sweet
- Processing: Minimal, focuses on contaminant removal
- Common Uses: Drinking water, soft drink and beer production
Distilled Water: Pure but Mineral-Free
Distilled water starts from any water source, but its defining process is distillation—a method that involves heating water until it becomes steam and then condensing that steam back into liquid. This process effectively strips away almost all impurities, minerals, and dissolved solids, making distilled water one of the “purest” forms available.
The consequence of removing minerals is a neutral, slightly flat taste that some find unappealing for regular drinking. However, this purity makes distilled water invaluable for applications where mineral content could cause problems—medical settings, laboratories, steam irons, and humidifiers.
Although distilled water is safe to drink, the absence of minerals also means it lacks those elements some may look for in everyday hydration. For many health experts, the body’s primary mineral source should be dietary, not water. Yet, some argue that drinking water containing natural minerals is beneficial.
What others are reading
Main attributes of distilled water:
- Source: Can be tap, well, or spring
- Purification: Boiling, vaporizing, condensing
- Mineral Content: None (fully stripped)
- Taste: Very neutral, sometimes described as “flat”
- Best Uses: Medical, laboratory, household appliances
Purified Water: Flexible Filtration and Clean Hydration
Purified water refers to water that has undergone extensive filtration to remove contaminants, including chemicals, bacteria, and metals. The purification methods most commonly employed are reverse osmosis, distillation, and carbon filtration. The major difference from spring water is that purified water can start from any source, frequently tap water, and is not necessarily mineral-rich.
Depending on the method, purified water may have either low or no minerals. Some manufacturers may add minerals back after purification to improve taste, leading to products labeled as “mineral water.” The taste is clean and neutral, with no significant flavor notes from minerals.
Regulated for safety, purified water must meet strictly defined limits for allowable contaminants. It’s widely preferred for those seeking the cleanest possible hydration, and also for use in sensitive applications such as laboratories, health care, and certain household appliances.
Purified water highlights:
- Source: Any water, typically tap
- Methods: Distillation, reverse osmosis, carbon filtration
- Mineral Content: Low to none; sometimes re-added
- Taste: Neutral, clean
- Common Uses: Drinking, technology, home use
Comparing Source and Filtration
Distinguishing the types of water starts with their sources and how they’re filtered or processed:
- Spring Water: Harvested directly from springs or aquifers; filtered naturally and minimally processed to meet safety standards while retaining minerals.
- Distilled Water: Created by distillation from any water source; all minerals and almost every impurity removed.
- Purified Water: Origin can be tap or surface water; processed by distillation, reverse osmosis, or carbon filtration to eliminate contaminants.
Mineral Content and Taste
The most pronounced difference consumers notice is flavor, determined primarily by mineral content:
- Spring water tastes vibrant or crisp due to retained minerals, which vary by region.
- Distilled water offers a very neutral, almost bland taste, lacking any mineral flavor.
- Purified water can be neutral; if minerals are added back, taste can resemble spring water.
While some prefer mineral-rich water for its flavor and perceived health benefits, purified and distilled water appeal to those who prioritize cleanliness and health safety.
Regulation and Safety
Bottled water of all types is regulated to ensure consumer safety:
- Spring Water: Must come from protected underground sources and be bottled at the source under strict hygienic conditions.
- Distilled Water: Annually tested for absence of microbial, chemical, and mineral impurities.
- Purified Water: Heavily regulated purification processes ensure the removal of contaminants and, in some cases, minerals.
Regulatory oversight is established by the FDA for bottled waters and the EPA for municipal sources. While all types are regulated for safety, the standards and required testing procedures differ.
Health Impacts and Practical Considerations
Choosing the right water type depends on individual priorities:
- Spring water offers natural minerals but can contain trace contaminants if not well regulated. It’s popular for daily hydration and beverage production.
- Distilled water guarantees purity, crucial for medical and industrial applications, but lacks flavor and minerals that some users appreciate.
- Purified water combines safety and versatility. Minerals may be added back to enhance taste or nutritional value.
Some experts believe minerals in water are not as easy for the body to absorb as those found in food, while others see a benefit in trace minerals from natural filtration. Ultimately, water intake quantity and overall diet tend to be far more important than water type.
Choosing the Right Water for You
When picking a bottled water, consider the following:
- Taste preference: Do you enjoy mineral flavor or prefer neutral?
- Health priorities: Is purity more important than taste?
- Intended use: For drinking, consider spring or purified. For appliances, choose distilled.
- Environmental impact: Bottled water has a carbon footprint and packaging waste; opt for local sources or filters when possible.
Both spring and purified water are suitable for daily drinking. Distilled water should be reserved for specialized applications unless you particularly enjoy its neutral taste or have medical reasons.
