Updated on | Water purity & drinking safety
Distilled water is one of the purest forms of water you can drink. It contains no minerals, additives, or contaminants, making it ideal for laboratory use, baby formula preparation, and home appliances. But is it healthy for everyday drinking? This guide explains everything you need to know including benefits, downsides, myths, and whether distilled water is safe for daily use.
What Is Distilled Water?
Distilled water is produced through a process called distillation water is boiled, turned into steam, then cooled back into liquid. This removes:
- Bacteria & microorganisms
- Heavy metals (lead, mercury)
- Minerals (calcium, magnesium)
- Salts & chemicals
- Sediment and impurities
The final result: pure H2O with no added minerals or contaminants.
Is Distilled Water Safe to Drink?
Yes distilled water is safe, clean, and non-toxic. Many people drink it daily without issues. It is often recommended when tap water quality is questionable or when the purest water is required (e.g., baby formula, medical machines).
The only difference: It contains no minerals, so it may taste flat compared to spring or mineral water.
Benefits of Drinking Distilled Water
- Extremely pure: No bacteria, chemicals, heavy metals, or contaminants.
- Ideal for compromised immune systems: Reduces risk from waterborne pathogens.
- Great for appliances: Prevents mineral buildup in humidifiers, CPAP machines, irons, and car batteries.
- Useful in emergencies: When tap water is unsafe due to contamination or boil-water alerts.
- Taste consistency: No minerals means the taste is stable everywhere.
Potential Downsides of Drinking Distilled Water
- No beneficial minerals: Lacks calcium, magnesium, potassium found in natural water sources.
- Taste: Many people find distilled water “flat” or less refreshing.
- Not ideal as your only water long-term: Slightly reduces mineral intake if your diet is poor.
- May cause faster hydration loss during intense activity: Lacks electrolytes needed for sweating.
Is It OK to Drink Distilled Water Every Day?
Yes. If your diet includes enough minerals from food, drinking distilled water daily is safe. Many health organizations, including the CDC and WHO, confirm that distilled water is suitable for drinking.
However, for best taste and hydration balance, many people prefer alternating with filtered, mineral, or spring water.
