The technology was\u00a0originally invented as a solution to<\/strong><\/p>\n

    \n
  1. Desalinate brackish<\/strong>\u00a0water or sea water to make it drinkable<\/li>\n
  2. Reduce very specific chemical<\/strong>\u00a0contaminants such as heavy metals<\/li>\n<\/ol>\n

    RO\u00a0is a process through which water pressure pushes the tap water through a semipermeable membrane that allows relatively small water molecules, but not larger molecules such as dissolved minerals (e.g. Salt) to pass through. Thanks to the process the pure tap water is separated from all other substances found in the water.<\/p>\n

    Here\u2019s what a\u00a0typical RO installation<\/strong>\u00a0looks like<\/strong> along with some of the maintenance requirements.<\/p>\n

    What does Reverse Osmosis filters remove?<\/h2>\n

    RO systems remove contaminants from water including bacteria, viruses, nitrates, sulfates, fluoride, arsenic and much more<\/strong>. But they also removes healthy minerals such as magnesium, calcium, potassium and sodium. Overall RO filters can remove 100s of substances from tap water with a 99% or higher filtration efficiency rate. Some high pressure professional RO filters such as Blue Water even claim 99.99%.<\/p>\n

    Low cost RO filters on the other hand generally have a much lower efficiency. Therefore it\u2019s really important that you look at the independent lab tests and certifications of each specific brand and product.<\/p>\n

    RO does not remove chlorine or soften the water very efficiently. Therefore activated carbon filters are almost always required in combination of RO<\/strong>. The activated carbon also helps remove 70+ other contaminants such as pesticides, herbicides, chlorine bi-products, pharmaceuticals and more.<\/p>\n

    RO filters reduce TDS<\/h2>\n

    \u201cThe sales guy used a TDS tester to justify the need for a RO system\u201d<\/b><\/p>\n

    TDS measures the amount of dissolved substances in the water. Often the sales technicians use this as an argument for needing a water filter. The problem is that TDS is not a good measurement of clean water. The main components of TDS are typically calcium, magnesium and bicarbonates that the human body needs. A TDS of 250 ppm for example normally just means that the tap water is high in minerals which is good.<\/p>\n

    Do I need a RO filter to get clean drinking water at home?<\/h2>\n

    Over the past 10-15 years RO systems combined with activated carbon have been marketed as the only solution for household drinking water. In some cases households can really benefit from a RO filters. However, for public tap water in Europe and North America\u00a0RO filters are generally a waste of money and water.<\/strong><\/p>\n

    Before purchasing an RO unit or any other water treatment equipment check the quality of your local tap water and what is required to make it safe and tasty. Don\u2019t listen to the sales guy.<\/p>\n

    What are the advantages (pros) of RO filters?<\/strong><\/p>\n

      \n
    • Proven technology for pure drinking water<\/li>\n
    • High quality filtration for non-potable tap water with e.g. bacteria or heavy metals<\/li>\n
    • Can make tap water with extremely high mineral content (TDS of 1500 or higher) drinkable<\/li>\n<\/ul>\n

      What are the disadvantages (cons) of RO filtration?<\/b><\/p>\n

        \n
      • Wastes as much as\u00a06x the amount of clean water produced\u00a0<\/strong>(some products are much more efficient)<\/li>\n
      • Requires professional maintenance<\/strong>\u00a0to ensure effectiveness and safety<\/li>\n
      • Water may taste flat and will make\u00a0coffee\u00a0and\u00a0tea\u00a0taste worse unless water is remineralised<\/li>\n
      • Removes healthy minerals including calcium, magnesium, potassium and bicarbonates<\/strong><\/li>\n
      • Relatively expensive starting from $300<\/strong>\u00a0+ maintenance and replacements<\/li>\n
      • Risk of bacteria growing in the water<\/strong>\u00a0after the filter since the chlorine has been removed<\/li>\n<\/ul>\n

        Is demineralized water from reverse osmosis filters good for you?<\/h2>\n

        No, it\u2019s actually not. According to the World Health Organization, low mineral (TDS) drinking water produced by reverse osmosis or distillation is not suitable for long term human consumption and in fact, can create negative health effects to those consuming it. This lack of minerals may also impact the taste negatively for many people.<\/p>\n

        With a good diet the minerals from tap water is not critical for you however so therefore drinking demineralized water will not be an issue.<\/p>\n","protected":false},"excerpt":{"rendered":"
