Firstly, we need to understand the difference between the two and then we can take a decision which one would be better to choose? 

The real mineral water haile from natural springs, which are pure and has minerals present in it naturally. It actually doesn’t require any treatment other than the removal of turbidity. It is not easily available and what we normally get in the name of mineral water is filtered water in which minerals are added after filtration.

Whereas, RO water purifier helps in retaining the minerals present in water. Here no addition of minerals takes place rather it retains the existing ones.  

The core difference between the two is about the source from where water is obtained in the first place. The source of mineral water needs to be a spring in clean and nascent surroundings free of any contaminants, harmful bacteria etc. This kind of water is organic, pure H2O or pure mineral water. The minerals that are beneficial for health are present in it naturally. It is the natural water that does not require any purification treatment before bottling it up. The only requirement is filtering it through hard strains, which can be stones of various sizes or sand to remove unwanted contaminants from it. This type of water is very limited and once you start filling it up commercially you can soon compromise the source.

RO water can be harvested from any source as it is treated by reverse osmosis technology to make it fit for consumption. Earlier, chemical treatments were done, but now consumers and organizations are considerate towards the environment and thus apply eco-friendly methods of purification. The RO method just uses pressure to purify water.
