What is distilled water?
Distilled water is a liquid obtained through the process of separating pure water from any dissolved impurities and mineral salts. As a result, we obtain ultra-pure water with extremely low electrical conductivity and almost complete absence of chemical compounds.
Key propertiesdistilled water:
- Practically no mineral ions.
- Very low electrical conductivity.
- Neutral taste and smell.
The resulting water has a wide range of applications both in households and in various branches of industry.
What is water distillation?
Distillationdistillation is a purification method in which the liquid is heated to its boiling point and then the water vapor is condensed, separating it from the original impurities. In this way, distilled water is obtained in the form of an almost perfectly pure liquid, containing negligible amounts of ions or microorganisms.
Water distillation – how does this process work?
The distillation process involves heating the water to the boiling point,the liquid. This steam goes to the condenser (cooler), where it condenses and turns back into liquid. This process removes most dissolved substances, resulting in high purity of distilled water.
In practice:
- Water goes into a vessel, where it is heated.
- Water vapor rises, separating frompollutants.
- Condensed steam is the final product, which is distilled water.
The whole process is relatively simple, but it requires maintaining appropriate temperature and technical conditions.

Distilled water formula – what does H2O really mean?
Although the chemical formula of distilled water is still well known H2O, the key factor here is the almost complete absence of ions from other elements. In regular tap water, we find various mineral additives, while in ultra-pure distilled water, the concentration of these chemical compounds remains negligible.
Distilled water vs demineralized water – what are the differences?
In everyday use, we often encounter products described as waterdemineralized and distilled. Although both undergo purification processes, the difference between distilled water and demineralized water lies in the method used to achieve purity.
- Distilled and demineralized water – both have very low mineral content.
- Distillation – involves evaporating and then condensing the vapor (physicalthe separation of pollutants).
- Demineralization of water – is based on ion exchange and other processes (e.g. reverse osmosis) to remove dissolved minerals.
It's worth remembering: The use of demineralized and distilled water can be similar, although in some industries (e.g. laboratory analysis) it is requiredis the absolute highest purity that distillation provides.
Uses of distilled water – what do we use it for?
Distilled water is used in a variety of fields, ensuring the absence of harmful residues or chemical reactions. If you plan to use distilled water on a daily basis, learn about the most popular areas of application.
Distilled water for irons – why is it worth using?use?
Using distilled water in irons is a way to avoid the formation of limescale and deposits that can clog steam channels. The use of demineralized or distilled water in the iron:
- Prevents limescale buildup.
- Protects the device from malfunction.
- Allows for longer, trouble-free operation.
Distilled water for batteries – safe use
Inside car batteries, there is an electrolyte that requires replenishment with only the purest water. Therefore, distilled water in batteries is a necessity – any mineral impurities could shorten the battery's lifespan. Remember that distilled water for batteries increases safety and reduces the risk of corrosion of the battery plates.
Waterdistilled water in the aquarium – pros and cons
Distilled water for the aquarium may tempt aquarists due to its almost zero mineral content. However, the distilled water used in the aquarium should be properly balanced with essential trace elements beforehand. The pros include the ability to precisely control water parameters, while the cons involve the risk of excessive sterilization of the environment if aquarium salts or stabilizing preparations are not added.
Other uses of distilled water
The list of places where distilled water is used is very long and includes, among others:
- Cosmetic industry – perfumed waters, tonics, creams.
- Pharmaceutical industry – production of medicines and injectable solutions.
- Laboratories – preparation of reagents, washing laboratory glassware.
- Food industry – in some technological processes where high purity is required.

Can distilled water be drunk? Facts and myths
Around the question "can distilled water bedrinking water?” many misunderstandings have arisen. Experts agree that drinking distilled water does not pose a direct health risk in small amounts, as distilled water is still H2O – it is not toxic or contaminated. However, consuming large amounts of such water on a daily basis is not recommended.
Arguments for and against regular drinking
- FOR - Pure, free ofbacterial contaminants.
- AGAINST - Lack of essential minerals for the body, risk of electrolyte depletion.
Key thought: Most dietitians recommend choosing mineral water or filtered tap water, which is richer in nutrients. Therefore, drinking distilled water in your daily diet is likeit is not a threat, as long as it does not become the main source of fluids.
Does distilled water conduct electricity?
Pure distilled water conducts electricity very poorly. Electrical conductivity mainly depends on the ions dissolved in the water, and in the case of distilled water, there is a negligible amount of them. However, in practice, any interaction with the environment (e.g., touching with hands or a container) introduces some impurities into the liquid, which means that evenpure water has minimal, but still detectable, conductivity after a while.
How to make distilled water at home?
Although industrial devices guarantee the highest purity, it is possible to prepare distilled water in the comfort of your home by following the steps below:
- Boil water in a pot.
- Place a bowl on top of the pot so that the steam can condense in it (you canuse the lid turned upside down.
- Place ice cubes in the lid (the cold surface will facilitate condensation).
- Collect the condensed liquid from the bowl – this is your homemade distilled water.

Is the water from the dryer distilled? Fact or myth?
Many people believe that the water coming from the condenser dryer is waterdistilled. Unfortunately, this is a myth. Although it is relatively soft, it can still contain residues from powders or fabric softeners. Therefore, it is not fully safe to use as distilled water – especially in devices such as irons or batteries.
Water distiller – what is it and is it worth buying?
Water distillers are devices designed for home or professional production of distilled water. The process occurs inan automated way: you pour tap water, and the device heats, condenses, and collects it by itself. Their prices range from several hundred zlotys to even several thousand – depending on efficiency and additional features. Purchasing a distiller can be cost-effective if you regularly need large amounts of ultra-pure water.
Where to buy distilled water? Buying guide

What instead of distilled water? Alternatives
If you don't have distilled water on hand, boiled water or well-filtered water can work for some applications.filtered, especially using modern filters for water (ion exchange, reverse osmosis). In many cases, such water is sufficient, e.g., for an iron or a humidifier.
pH of distilled water – chemical properties
Although theoretically the pH of pure water H2O is 7, the pH of distilled water in practice varies slightly due to its susceptibility to contact with carbon dioxide.of water. Right after preparation, its pH can be around 7, but it quickly drops to 5.5–6.5. However, in most applications, this does not have a negative impact.
Summary – is it worth using distilled water?
Distilled water serves many important purposes: it protects irons from scale, supports battery operation, and ensures absolute purity in laboratories or industry. If you want to usedistilled water at home – for household appliances or specific hobby applications – is a great and inexpensive option. However, drinking distilled water as a substitute for mineral water should not be a daily practice, as the body needs minerals. In summary: it is worth reaching for "distillate" where the purity and safety of devices are crucial, while on a daily basis, it is important to ensure healthy drinking water with the appropriate mineral composition.
