Is drinking RO water not good for health?

There is a vicious campaign going on on social media saying that RO water is not good for health because it is too pure! As an expert in the water purification Industry, I can categorically state that it is a lie. RO water is the safest drinking water you can possibly get out of a water purifier. All bottled water manufacturers use RO to purify the water before bottling and then add the necessary minerals to make the water neutral and taste better. Most RO water purifiers have a remineralising cartridge which does the same job.

The most significant advantage of an RO water filter purifier is that it can remove dissolved chemicals in water, including the poison Heavy Metal salts from water. RO water purifier also removes the smallest of viruses from water. Since an RO water purifier removes everything from water, RO water purifier produces pure water to which purified minerals are added.

Some say that because RO water purifier removes everything, including any essential minerals the water may contain, it is not good. This is not true, essential mineral for our body should come from the food we eat and not from the water we drink, as explained in our page on advantages and disadvantages of RO water purifiers.

In India the Wall Mounted Water filters are more common. But in Kitchens with modern Kitchen Cabinets and a kitchen sink, it is more practical and better to fix an Undersink RO water purifier as explained in our Under Sink RO purifier page.
