It is unbelievable. A reverse osmosis water dispenser which was a top favorite once, seems to be gradually loosing its charm. With the growing awareness, people today are much more aware. If you have missed the details, here is a quick fact-sheet for you.
First things first. We need to understand how a reverse osmosis water dispenser works. It has a semi permeable membrane which has ultra fine pores on it. The contaminated water is forced to pass through this membrane. What is filtered and what is not, entirely depends on the molecular size of the contaminant.
OSMOSIS
Since water molecules are smaller than that of the pores, they pass through. Chemical and organic contaminants are larger in size, hence they are left behind. Thus they are separated from the water.
Fact 1: The pharmaceutical drugs which are a common contaminant have a small molecular size. The size is so small that they can easily pass through the porous membrane of a reverse osmosis water dispenser. Thus the water filtered from a RO is still contaminated and is still not pure.
Fact 2: The essential minerals like magnesium, sodium, iron found in the natural water have a large molecular size. Since their size is larger than that of the membrane, they are not able to pass through it, and are separated out from the water. Thus a reverse osmosis water dispenser ends up in de-mineralizing the water.
This de-mineralized water lacks all these minerals which are actually important for our health. Drinking water is one of the main sources of providing these minerals to our body. Consuming de-mineralized water results into mineral deficiencies, due to which various health problems occur. If you are consuming this water, you must take multi vitamins or supplements to meet the required content of these minerals in your body.
Moreover, since these minerals have been taken out, the water doesn't tastes good anymore.
Solution: The easy and proven solution to this problem is to use a multi-stage water purifier. These filters work by a combination of ion exchange and carbon filtration techniques. They are efficient in removing all types of organic and synthetic pollutants from the water, even the pharmaceutical drugs. They also enhance the pH in the water.
Unlike RO filters, they do not separate out essential minerals, thus retaining the form water is available in the nature - free from impurities and rich in minerals.
In conclusion, before selecting a filter, make sure to review and analyze the facts. The effective alternatives to reverse osmosis water dispenser are available. You just need to look for it and carefully pick the right water purifier.
