7 Things You Must Know Before Purchasing a Reverse Osmosis Water Dispenser

 


Visitors: 154

Boy, did I learn a valuable lesson. After reading all the big news about tap water being contaminated with a variety of chemicals, including prescription drugs, I was floored and decided to take action. I was about to buy a reverse osmosis water dispenser but I did some research and realized that it would be a big mistake. Many people like me are coming to the conclusion that this type of water dispenser is more costly and less effective than other water filtration systems. Based on the information I found, here are 7 things I think anyone should consider before buying a reverse osmosis water purification system.

1. Many synthetic chemicals like pesticides and herbicides cannot be removed from water when reverse osmosis water filtering systems are used. In order to understand why this happens, let me quickly explain how reverse osmosis works. Water is exposed to a semi-permeable membrane with a fine porous structure under pressure. Inorganic contaminants have a larger molecular size than water so the membrane rejects them.

The problem is that the synthetic chemicals mentioned above have a smaller molecular size than water thus they can't be removed effectively by reverse osmosis. A carbon filter needs to be used in conjunction with this system in order to remove these chemicals with a smaller molecular size. So that makes me wonder. . . why not just use a carbon filter to begin with?

2. When water passes through the membrane of a reverse osmosis water dispenser, inorganic compounds and trace minerals with a larger molecular size don't make it through. That means that water treated by reverse osmosis is stripped of its natural mineral content. All natural water sources contain minerals because we need them in order to stay healthy. By drinking demineralized water, you could end up with multiple mineral deficiencies and an increased risk of cancer. You might think this is an exaggeration but believe me, there are scientific studies to back it up.

3. According to the American Medical Association (AMA), some findings indicate that reverse osmosis water dispensers actually cause the concentration of harmful heavy metals like aluminum and mercury, both of which have been linked to a variety of neurological disorders.

4. Reverse osmosis water filtering systems require a lot of maintenance. They also require very good water pressure.

5. Reverse Osmosis systems are painfully slow. A reverse osmosis water dispenser will produce less than a gallon per hour and in order to use one you need a diaphragmed storage tank.

6. Reverse osmosis water filtering systems are wasteful and environmentally unfriendly. They waste around two to three gallons of water for every gallon they produce.

7. Investing in a reverse osmosis water filtering system is more expensive than other methods of water purification. It costs 18 to 24 cents per gallon whereas carbon block filters cost a little less than 10 cents per gallon. Then there is the fact that you have to purchase new membranes every now and then, which can cost you $50 to $150 for a decent one. The companies that sell reverse osmosis systems claim that the membranes last many years but based on most customers’ experiences, it is simply untrue.

Your goal? Take some time to think about whether a reverse osmosis water dispenser is right for you. Countless scientific studies and testimonials will point out that the cons outweigh the pros. To get the most bang for your buck, carbon block filters are recommended but ultimately the decision is yours. Take what you have learned and go out and compare water filters. If you do so, you will find that some water filtration systems simply don't cut it while others offer you more results for less money.
