Deionised Water
About Deionised Water
Deionised Water (DI Water) is ultra-purified water that has had all of its mineral ions removed — including sodium, calcium, iron, copper, chloride, and sulphate. The result is an extremely pure and neutral water that won’t cause limescale build-up, corrosion, or chemical interference. Because of its purity, Deionised Water is widely used in industries ranging from automotive and cleaning to cosmetics, laboratories, and manufacturing.

Deionised Water FAQ's
Deionised Water is water that has undergone a purification process to remove dissolved mineral ions such as sodium, calcium, magnesium, and chloride. This is achieved through a method called ion exchange, where charged resin beads attract and remove these ions. The result is highly pure water with minimal electrical conductivity, making it ideal for applications where normal tap water would cause contamination, corrosion, or residue. Deionised Water is different from distilled water, which is purified through boiling and condensation — DI Water is typically purer and more efficient for industrial use.
Deionised Water has a wide range of applications. In the automotive industry, it’s used in car batteries, cooling systems, and windscreen wash to prevent limescale and corrosion. In laboratories, it’s used for equipment cleaning and chemical dilution where impurities could interfere with results. In cosmetic and pharmaceutical manufacturing, it serves as a clean base for formulations to maintain product stability. It’s also commonly used in steam irons, humidifiers, and cleaning electronics, where mineral-free water is essential to avoid damage or residue.
No — Deionised Water is not intended for drinking. While it’s free from minerals and contaminants, it also lacks essential minerals that make water suitable for consumption. It is, however, completely safe to handle and is perfect for industrial, cleaning, and laboratory use. If you require purified water for food or beverage production, we recommend using distilled or reverse osmosis (RO) water certified for food-grade applications.
