slai60大您好,
最近發現您在本區許多討論串下都有"WHO世界衛生組織都不建議喝純水了"的討論，
基本上WHO並不是什麼神祕組織，小弟提供官網連結在下面
http://www.who.int/en/
基本上我查不到WHO有發表過"WHO世界衛生組織都不建議喝純水了"的言論或報告，
而RO全名為Reverse osmosis，查詢後有數十筆資料，
其中有多篇將RO定位為more advanced treatment processes，
一樣提供其中一篇的連結
http://www.who.int/water_sanitation_health/diseases-risks/risks/info_sheet_pharmaceuticals/en/
既然您振振有詞的提出您的看法，是否麻煩您也提供一下佐證資料，
基本上網路內有相關"WHO世界衛生組織都不建議喝純水了"討論的文章，
背後都是在推薦非RO淨水設備，假如真要WHO來背書，
能否請您提供一下相關資訊(當然要以WHO官網查得到的為主)。

這就是我說有很多{網路內有相關"WHO世界衛生組織都不建議喝純水了"討論的文章，背後都是在推薦非RO淨水設備}
這篇文章我GOOGLE過，其中有一段我節錄下來
In this chapter, demineralised water is defined as water almost or completely free of dissolved minerals as a result of distillation, deionization, membrane filtration (reverse osmosis or nanofiltration), electrodialysis or other technology. The total dissolved solids (TDS) in such water can vary but TDS could be as low as 1 mg/L. The electrical conductivity is generally less than 2 mS/m and may even be lower (<0.1 mS/m). Although the technology had its beginnings in the 1960’s, demineralization was not widely used at that time. However, some countries focused on public health research in this field, mainly the former USSR where desalination was introduced to produce drinking water in some Central Asian cities. It was clear from the very beginning that desalinated or demineralised water without further enrichment with some minerals might not be fully appropriate for consumption. There were three reasons for this:
• Demineralised water is highly aggressive and if untreated, its distribution through pipes and
storage tanks would not be possible. The aggressive water attacks the water distribution piping
and leaches metals and other materials from the pipes and associated plumbing materials.
• Distilled water has poor taste characteristics.
• Preliminary evidence was available that some substances present in water could have
beneficial effects on human health as well as adverse effects. For example, experience with
artificially fluoridated water showed a decrease in the incidence of tooth caries, and some
epidemiological studies in the 1960’s reported lower morbidity and mortality from some
cardiovascular diseases in areas with hard water.
有興趣的人自己研究一下，而demineralised water就是被這些廠商引用為純水，但我怎麼看都不像。
而此篇文章有建議應該從水中攝取鎂跟鈣，這又是另一個討論到爛的話題了，請問人一天所需的鎂跟鈣假如都從飲用水取得，請問一天要喝多少水？
這篇文章我認為本意不是在說"不建議喝純水了"！
