Distilled water is a type of purified water that has been boiled to create steam and then cooled to form liquid again. This process removes impurities, minerals, and contaminants, making it very pure. It is often used in laboratories, medical settings, and for certain household appliances like steam irons. Because it lacks minerals, distilled water is not typically recommended for regular drinking. Some people may find it flat or bland compared to regular tap or bottled water. However, it is useful in situations where pure water is essential, such as in aquariums or for car batteries.
