Deionized water is not the same as distilled water. Both deionized and distilled water are purified, but through different processes — distillation uses heat while deionization uses ion exchange.

Deionized water, also called deionised water, DI water, or demineralized water — is water that has had ions removed. Ions are molecules with a positive or negative electrical charge. In water, they appear as dissolved mineral salts. Minerals commonly found in tap water include calcium, magnesium, iron, sodium, chloride, sulfates, nitrates, carbonates, and silica.
High concentrations of these minerals create hard water. If you’ve ever had hard water in your home, you know it’s difficult to manage. When hard water dries on surfaces, it can leave a scaly residue that’s hard to clean. Hard water is also corrosive, not only to your appliances and fixtures, but also to your skin and hair.In deionization, water is pushed through a tank or cartridge that’s lined with positively and negatively charged resin beads. The beads attract ions with the opposite charge, essentially pulling them from the water. The water runs through the system, and the ions stay behind. This process is called ion exchange.
Notably, deionization only removes ions. Uncharged contaminants and suspended solids, including viruses and bacteria, can remain in deionized water.
