Distilled water (Benefits) is one of the purest forms of water available, widely used in medical, industrial, and household applications. But what exactly is distilled water? How does it differ from purified or spring water? And is it safe to drink?
In this comprehensive guide, we’ll explore the benefits, uses, and potential risks of distilled water, along with how it compares to other types of water.
What is Distilled Water?
Distilled water is water that has been boiled into steam and then condensed back into liquid in a separate container. This process removes impurities, minerals, and contaminants, leaving behind nearly pure H₂O.
Because of its high purity, distilled water is commonly used in:
- Medical equipment
- Laboratories
- Automotive cooling systems
- Household appliances
- Drinking (in some cases)
How is Distilled Water Made?
The distillation process involves:
- Boiling – Water is heated until it turns into steam.
- Condensation – The steam is cooled and collected in a separate container, leaving behind impurities.
- Collection – The condensed steam becomes distilled water.
DIY Distillation:
You can make distilled water at home using:
- A large pot with a lid
- A heat-resistant bowl
- Ice (to speed up condensation)
However, commercial distillation systems are more efficient for large-scale production.
Distilled Water vs. Purified/Spring/Deionized Water
1. Distilled Water vs. Purified Water
- Distilled Water – Free from almost all impurities, including minerals.
- Purified Water – Filtered (via reverse osmosis, carbon filters, etc.) but may retain some minerals.
2. Distilled Water vs. Spring Water
- Spring Water – Naturally sourced, contains minerals like calcium and magnesium.
- Distilled Water – No minerals, completely neutral.
3. Distilled Water vs. Deionized Water
- Deionized Water – Removes ions (salts, minerals) but may contain organic impurities.
- Distilled Water – Removes both minerals and most organic contaminants.
Health Benefits of Distilled Water
While distilled water lacks minerals, it has some benefits:
- Free from Contaminants – No heavy metals, chemicals, or bacteria.
- Helps Detoxify the Body – Some believe it aids in flushing out toxins.
- Good for Medical Use – Used in surgeries, CPAP machines, and baby formulas.
However, long-term consumption may lead to mineral deficiencies since it doesn’t provide calcium, magnesium, or electrolytes.
Common Uses of Distilled Water
1. Medical & Laboratory Applications
- CPAP machines (prevents mineral buildup)
- Sterile medical procedures
- Pharmaceutical preparations
2. Automotive & Battery Maintenance
- Car batteries (prevents corrosion)
- Cooling systems (reduces mineral deposits)
3. Household Uses
- Steam irons (prevents clogging)
- Aquariums (for sensitive fish species)
- Plants (some plants thrive in mineral-free water)
Is Distilled Water Safe to Drink? Risks & Myths
Potential Risks:
- Lack of Minerals – May contribute to electrolyte imbalances if consumed exclusively.
- Flat Taste – Some find it bland compared to mineral-rich water.
Debunking Myths:
- “Distilled water leaches minerals from the body.” – Partially true, but a balanced diet compensates.
- “It’s completely dead water.” – While lacking minerals, it’s still safe for short-term use.
Verdict: Safe for occasional drinking, but not ideal as a primary water source.
Distilled Water for Appliances (Irons, CPAP, Batteries)
- CPAP Machines – Prevents mineral buildup in humidifiers.
- Car Batteries – Extends battery life by reducing corrosion.
- Clothing Irons – Avoids mineral deposits that clog steam vents.
Where to Buy Distilled Water? (Stores & DIY Options)
Retail Options:
- Grocery stores (Walmart, Target, etc.)
- Pharmacies (CVS, Walgreens)
- Online (Amazon, Walmart.com)
DIY Distillation:
- Home distillation kits
- Stovetop method (as described earlier)
FAQs About Distilled Water
1. Does distilled water expire?
No, but stored improperly, it can absorb contaminants from the air.
2. Can you use distilled water for cooking?
Yes, but it may alter the taste of food due to lack of minerals.
3. Is distilled water good for plants?
Some sensitive plants prefer it, but most benefit from mineral-rich water.
4. What’s the pH of distilled water?
Around 7 (neutral), but it can become slightly acidic when exposed to air.
Conclusion: When to Choose Distilled Water
Distilled water is ideal for:
- Medical & laboratory use
- Appliances (irons, CPAP machines, batteries)
- Short-term detox or emergency drinking
However, for daily hydration, mineral-rich purified or spring water is a better choice.
Final Recommendation:
Use distilled water where purity is crucial, but balance it with mineral intake from food or supplements if drinking it regularly.
By understanding the benefits and limitations of distilled water, you can make informed decisions for your health and household needs. Whether for medical use, appliances, or occasional drinking, distilled water remains a valuable resource in purity-driven applications.
