Q:

Is distilled water the same as demineralized water?

A:

Distilled water and demineralized water are both types of purified water, but they are made with different processes. Distilled water is heated above the boiling point to become water vapor. The vapor is collected in a separate container, leaving the impurities behind. The vapor returns to liquid as distilled water.

Demineralized water is made by passing water through ion exchange resins. The water exchanges contaminating anions and cations with hydrogen and hydroxide, which combine to form water. Both types of water meet international quality standards, but demineralized water is cheaper than distilled water. Demineralized water can be used for most of the same things as distilled water, except in some situations such as lead-acid batteries in vehicles or the enameling industry, in some laboratories, and as a coolant for nuclear-reactors in ships and submarines.

  • Q:

    Does distilled water have chlorine in it?

    A:

    Distilled water may have chlorine in it if special steps are not taken to remove it. Distillation involves boiling water and condensing the steam into a clean container. If done correctly, the water should be cleaner, but toxins may still exist.

  • Q:

    What is the difference between purified and distilled water?

    A:

    The difference between distilled and purified water lies in the process that the water goes through; distilled water goes through one specific process, while purified water can go through a number of different cleaning processes and still have "purified" on the label. The distillation process boils all the contaminants out of water, but purification takes on a number of different guises.

  • Q:

    How can water be made fluoride-free?

    A:

    Fluoride can be removed from water through reverse osmosis filtration, distillation filtration and the use of an activated alumina defluoridation filter, according to Anne Marie Helmenstine at About.com. Boiling water, freezing water and using common water filters are ineffective filtration methods and do not remove fluoride from water.
