Purified Water Types

Demineralized water is a category, it doesn't refer to the type of purification. Deionised, distilled and ultrapure all demineralized (I.e. minerals removed). The difference between them is the methods used and therefore the output will differ in quality.

 

Types of Purified Water –

There are three main types of Purified Water.

  1. Deionised water
  2. Distilled water
  3. Ultrapure water

 

1. Deionised water

Deionised water is normally very low in minerals, but has very little effect on bacteria.

Typically used in steam irons, steam cleaners, car washing and polishing.

 

2. Distilled water

Distilled water has ultra low levels of bacteria and minerals but is the most costly to produce.

Typically used For more sensitive applications such as cell culture, lab glassware washing, high power laser cooling, ultrasonic cleaning and cosmetics.

 

3. Ultrapure water

Ultrapure water is ultra low in bacteria and minerals.

Typically used for medical use such as intravenous medicine (injections), open wound cleaning and any other application where ultra high purity is required.

 

Conclusion

That all may sound complicated but for most household uses de-ionised water is plenty good enough, if you want to step it up a notch without paying a fortune go for distilled water. Ultrapure water is mostly way beyond the requirements for most consumers, it can be difficult to purchase and has a short shelf life.
