Availability of genuine distilled water in UK supermarkets can vary, and products labelled purified, demineralised or ironing water are not necessarily produced by distillation.

If you need distilled water specifically, check the product description and purification method rather than relying on appearance alone. Our UK distilled water buying guide explains the different options and what to look for.

Distilled water is used wherever low-mineral water is preferred. Common applications include steam appliances, humidifiers, CPAP humidifier chambers, automotive applications, cleaning and a variety of domestic, commercial and technical uses.

Distilled and deionised water are both highly purified forms of water, but they are produced differently. Distilled water is produced using distillation, where water is evaporated and the resulting steam is condensed back into water. Deionised water is produced using ion-exchange technology to remove dissolved ions.

The best option depends on what you're using the water for. Some applications specifically call for distilled water, while deionised water is widely used for cleaning, automotive, industrial and technical purposes.
