What is the difference between potable water and demineralized water?

Potable water is safe for human consumption and meets health standards for drinking water, containing essential minerals and nutrients. In contrast, demineralized water has had most of its mineral ions removed through processes like distillation or ion exchange, making it unsuitable for drinking but ideal for industrial applications or laboratory use. While both types of water are purified, potable water retains beneficial minerals, whereas demineralized water does not.
