Distilled Water: A Comprehensive Guide to Its Benefits, Dangers, and Applications

The Allure of Distilled Water

With a growing consciousness about health and cleanliness, distilled water is surging in popularity. It promises purity unlike any other – a water source devoid of any contaminants, whether they be bacteria, chemicals, or minerals. This is precisely why distilled water finds favor in specific industries, notably in medical, industrial, and surgical domains.

Yet, while it may be pure, it lacks the essential minerals found in other water sources like spring or mineral water, and even in reverse osmosis-treated water. People, especially those caring for newborns or the infirm, may opt for distilled water due to its purity. However, constantly purchasing pre-packaged distilled water can be expensive and unsustainable in the long run. This rising demand has thus spurred a market boom for home water distillers.

The Science Behind Water Distillation

Water distillation, at its core, is a simple process hinged on capturing water’s steam. Here’s a basic breakdown:
  1. Boiling the Water: When water is boiled, it produces steam, which is free from contaminants present in the original water.
  2. Capturing the Steam: The steam is then directed to a separate chamber, where it cools down and condenses back into water.
  3. Collecting Distilled Water: The condensed steam, now pure water, is collected separately.
While the underlying concept can be replicated at home using basic kitchen equipment, having a dedicated water distiller simplifies and ensures the safety of the process.

Understanding Water Distiller Units

A water distiller unit is essentially a mechanized system that replicates the distillation process described above. The unit boils water, captures and cools the steam, and then collects the resulting distilled water. This distilled water, if processed correctly, should be free from contaminants and is deemed fit for varied uses, from laboratory settings to personal consumption.

Reasons to Consider Using a Water Distiller

Water distillers operate on the foundational principles of condensation and evaporation. But why should one consider using it?
  • High Purity: A well-maintained water distiller can eliminate over 95% of contaminants.  
  • Broad Spectrum of Removal: Distillers can get rid of compounds like sulfates, nitrates, and even certain heavy metals.  
  • Combatting Hard Water: Minerals like magnesium and calcium, which cause water hardness, are removed.  
  • Preference in Labs: Due to its high purity, distilled water is often favored in chemical labs.  
  • Fluoride Removal: Distillers can remove fluoride, which is a concern for many and not always addressed by standard filters.  
  • Economic and Eco-friendly: While bottled distilled water is available, having a distiller can be both cost-effective and environmentally friendly in the long run.


One limitation of water distillers is their capacity. They are designed for smaller quantities. For larger volumes, alternatives like Reverse Osmosis might be better.

Selecting the Ideal Water Distiller System for Your Needs

Before you invest in a water distiller, consider the following:

  1. Convenience: Different units, though based on the same principle, may offer varied user experiences.
  2. Space: Ensure the unit fits comfortably in your designated space.
  3. Aesthetics: Choose one that complements your kitchen’s design.
  4. Value for Money: Consider quality, speed, and features against your budget.
  5. Warranty: Opt for units that offer solid warranties or money-back guarantees.
  6. Safety Certifications: Always check for safety accreditations and positive user reviews.
  7. Safety Features: Features like automatic shut-offs are crucial for ensuring safe operations.
  8. Brand Reputation: As a rule, prefer brands with a track record of at least 5-10 years.
Understanding the nuances of distilled water, from its benefits to potential dangers, and how to choose the right distiller system, empowers consumers to make informed decisions tailored to their unique needs.
