deionized water

Water that has been passed through a substance that removes cations and anions present as contaminants. As ionic purity increases, so does the electrical resistance of the water.

CAUTION!

Deionization is not synonymous with sterilization. It does not remove bacterial, fungal, or viral pathogens from water.
