Distilled vs Purified Water: Taste, Purity, and Health

Distilled vs Purified Water – Water, the elixir of life, is a substance we encounter daily. It quenches our thirst, cleanses our bodies, and sustains all living things. When it comes to ensuring that the water we consume is of the highest quality, the terms “distilled” and “purified” often come into play. But what exactly do these terms mean, and how do they affect the taste, purity, and overall health? This article explores the distinctions between Distilled vs Purified Water, delving into their production methods, taste profiles, purity levels, and potential health implications.

The Essence of Distilled Water

Distillation Process

Distillation is the procedure used to produce distilled water. This method involves heating water to its boiling point, turning it into steam, and then cooling it to condense it into a liquid state. The condensed water is collected, resulting in distilled water. This process effectively separates water from impurities, minerals, and contaminants, leaving behind a highly pure form of H2O.

Taste Profile

Distilled water is renowned for its pure and neutral taste. Its lack of minerals and impurities gives it a clean, crisp, and tasteless quality. Some people find this taste refreshing, while others may describe it as “flat” due to lacking mineral flavors.

Purity Levels

One of the cleanest types of water is distilled water. The distillation removes most minerals, chemicals, and contaminants, making it ideal for various applications where purity is paramount, such as laboratory experiments, medical procedures, and specific industrial processes.

Health Considerations

Regarding health, distilled water is generally considered safe for consumption. Its purity makes it an excellent choice for individuals with specific medical conditions that require strict water purity, such as those undergoing dialysis. However, some argue that drinking distilled water over an extended period may lead to mineral deficiencies, as it lacks the minerals typically found in natural water sources.

Purification Methods

Purified water, on the other hand, is a broader category encompassing various water treatment methods aimed at removing impurities and contaminants. Standard purification methods include:

  1. Reverse Osmosis: This process uses a semipermeable membrane to filter out pollutants and contaminants.
  2. Filtration: Water can be purified through various filtration methods, such as activated carbon filters, which trap particles and remove odor and taste.
  3. UV Treatment: Ultraviolet (UV) light is employed to disinfect water by killing microorganisms.
  4. Chemical Treatment: Chemicals like chlorine or ozone can be used to disinfect and remove impurities from water.

Taste Profile

The taste of purified water can vary depending on the method used for purification. Water purified through activated carbon filtration often retains some mineral flavors, giving it a slightly more natural taste than distilled water. However, the taste of purified water can also be influenced by the source water and the specific purification process employed.

Purity Levels

Purified water is typically free from harmful contaminants and impurities. The purity level can vary based on the purification method and the efficiency of the treatment process. While it may not achieve the same purity level as distilled water, it is considered safe for most drinking purposes.

Health Considerations

Purified water is generally safe for consumption and widely used for drinking, cooking, and household purposes. Unlike distilled water, it usually retains essential minerals like calcium and magnesium, which can contribute to overall health. However, the quality of purified water can vary widely based on the specific purification process and the source water’s initial rate.

Taste Comparison: Distilled vs Purified Water

Personal tastes matter a lot when it comes to flavor. Some prefer distilled water’s clean, neutral flavor, while others find it lacking in character. Purified water, with its potential mineral content and varying taste profiles depending on the purification method, may appeal to those seeking a taste closer to natural spring water.

Regional factors also influence the taste of water, as the minerals present in the source water can differ from one location to another. This variation contributes to the diversity of water tastes experienced worldwide.

Purity and Health Considerations

Minerals in Water

One of the critical differences between distilled and purified water is its mineral content. Distilled water lacks minerals, which can be advantageous in some applications requiring mineral-free water. However, for everyday drinking, the absence of minerals in distilled water may not be ideal for long-term health.

Minerals like calcium, magnesium, and potassium are essential for various bodily functions, including bone health, muscle function, and nerve transmission. Drinking water that contains these minerals can contribute to meeting our daily mineral requirements.

Health Effects of Distilled Water

While distilled water is generally safe for consumption, concerns have been raised about its long-term health effects. Some argue that drinking exclusively distilled water over extended periods may lead to mineral imbalances or deficiencies in the body, as it lacks the minerals typically found in natural water sources.

It’s important to note that these concerns are primarily theoretical and are not supported by conclusive scientific evidence. Most people obtain essential minerals from their diet, so the impact of drinking distilled water on mineral intake is considered negligible for the average person.

Health Effects of Purified Water

Purified water, which often retains some minerals, is considered a safe and healthy choice for drinking. The mineral content in purified water may vary depending on the source water and the purification method. In some cases, pure water may even be fortified with minerals to enhance its nutritional value.

Practical Considerations: Choosing Between Distilled and Purified Water

The choice between distilled and purified water ultimately depends on individual preferences, needs, and specific circumstances. Here are some practical considerations to help you make an informed decision:

1: Intended Use

Consider the purpose for which you need the water. If you require water for medical procedures, laboratory work, or specific industrial applications that demand extremely high purity, distilled water may be the preferred choice due to its absolute purity.

2: Taste Preference

Your taste preference plays a significant role. If you prefer a clean and neutral taste, distilled water may suit your liking. However, purified water may be a better fit if you enjoy the subtle mineral flavors found in natural water sources.

3: Health Considerations

Take into account your health and dietary needs. If you rely on drinking water as a source of essential minerals, purified water may be a more suitable option, as it typically retains some mineral content.

4: Source Water Quality

The quality of your tap water or the source water you can access can influence your choice. If your tap water is high in impurities or contaminants, you may opt for a purification method that effectively addresses those issues.

5: Environmental Impact

Consider the environmental impact of your choice. The distillation process consumes a significant amount of energy due to the need for heating and cooling. Purification methods such as filtration or UV treatment may be more energy-efficient.


In the debate of distilled vs purified water, both options have their merits and are generally safe for consumption. Distilled water offers the highest purity level, making it suitable for specialized applications. However, it lacks minerals, which may be a consideration for long-term health.

Purified water, on the other hand, encompasses a variety of purification methods, some of which may retain beneficial minerals while effectively removing impurities. It often provides a taste closer to natural spring water, making it popular for everyday hydration.

Ultimately, the choice between distilled and purified water comes down to individual preferences, needs, and specific use circumstances. Whichever you choose, maintaining proper hydration is vital to overall health, and ensuring the water you consume is safe and meets your requirements is of utmost importance.
