De ionized water is created through a more in-depth process of filtering and distillation that includes resin and carbon filters to remove, or “de ionize”, ions from the other contaminants in the water. The end result of this process is considered significantly purer than ordinary distilled water,
De ionized Water also known as de mineralize water,Water is put through a process called ion exchange. This process removes nearly all ions, except for some trace minerals not present in tap water. Without these ions present, de ionized water has excellent purity characteristics and is often used by cosmetic formulators and also in laboratories or pharmaceutical applications ,due to its sterility and lack of contamination.

Aside from its use in scientific experiments, de ionized water is also commonly used for inverter batteries, industrial cleaning. Due to its purity, it doesn’t leave behind any soapy residue or scale build-up and is beneficial for processes that require a high degree of cleanliness. De ionized water can be used to wash parts and equipment and is often used in the food industry due to its non-toxicity. Additionally, because it does not contain hard minerals, it will not cause corrosion of metals like copper pipes.
