Distilled Water/Purified Water.

Went into our local branch of Boots the Chemist this morning, looking for 100ml of Distilled Water.

Of course they didn't have any. Not unusual, they rarely do have anything I want.

They phoned the nearest large branch and they said they only have "Purified Water" in 2lt containers.

Now I have no intention of buying 2lt, but what is the difference between Distilled Water and Purified Water?

Distilled water — Distilled water is a type of purified water. It’s water that has gone through a rigorous filtration process to strip it not only of contaminants, but any natural minerals as well. This water is best for use in small appliances — like hot water urns, or steam irons, because if you use it, you won’t have that mineral buildup that you often get when you use tap water. Though it may seem counterintuitive, this water is not necessarily the best for human consumption, since all of the water’s natural, and often beneficial, minerals are absent.



Purified water — Purified water is water that comes from any source, but has been purified to remove any chemicals or contaminants. Types of purification include distillation, deionization, reverse osmosis, and carbon filtration. Like distilled water, it has its advantages and disadvantages, the advantages being that potentially harmful chemicals may be taken out and the disadvantage being that beneficial minerals may be taken out as well.

Not really any difference. Pharma like to call it purified because it sounds better, more healthy
I used to buy 'de-ionised' water years ago for ultrasonic cleaning, same stuff.
