Now a days water comes in many forms, we want to compare bottled water vs. distilled water. Just because water is marketed and bottled real pretty doesn't mean it's always the best.
There's also flavored water, spring water and in this country we can market ice to an Eskimo, but is it healthy? I only know what I read and Distilled Water is the best. Why? Here are the top three processes in water quality:
Distilled water - has virtually all of its impurities removed through distillation. Distillation involves boiling the water and then condensing the steam into a clean container, leaving nearly all of the solid contaminants behind. Distillation produces very pure water but also leaves behind a leftover white or yellowish mineral scale on the distillation apparatus, which requires that the apparatus be frequently cleaned.
Double distilled water - is prepared by double distillation of water. Historically, it was the standard for highly purified laboratory water for biochemistry and trace analysis until combination methods of purification became widespread.
Deionized water - is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup. However, deionization does not significantly remove uncharged organic molecules, viruses or bacteria, except by incidental trapping in the resin. Specially made strong base anion resins can remove Gram-negative bacteria. Deionization can be done continuously and inexpensively using electrodeionization.
Distilled water should ideally be nothing but hydrogen and oxygen molecules, with a PH level of 7 and no additional gases, minerals or contaminants.The biggest argument, which I agree is loss of minerals. Anytime I suggest distilled water to anyone I always advise supplement minerals. This seems a small price to pay for having chemical free water.
Plastic Container Water Safety
The other issue we have with any liquid is plastic, the container and heat. Studies have shown that toxins and gases leech into the water when the plastic is warm. Glass is preferred but impractical for travel, the following plastics are tested safe:
* Polypropylene, designated "#5 PP"
* High-density polyethylene, designated "#2HDPE"
* Low-density polyethylene, designated "#4 LDPE"
Bottled water, purified water, filtered water all fall into another class and in some cases tap water is just as good. Remember when drinking distilled water especially for long periods requires mineral supplements, then all will be well.,
