While reverse osmosis filters are considerably better than drinking from the tap, there are facts every potential buyer should know before purchasing a reverse osmosis system. Truth #1: Reverse Osmosis Removes A Lot From Your Water This sounds like a good truth, and to some degree it is, but reverse osmosis also removes naturally occurring minerals from your water, such as magnesium, that your body relies on to maintain good health. Nowhere in nature will you find a naturally occurring source mineral-free. This is because living things need these minerals and have come to expect them within the water they drink. R.O. removes a number of chemicals and contaminants, and these systems also have a carbon filter to remove chemicals not eliminated through R.O., but the cost is the loss of naturally occurring and necessary minerals. Truth #2: Reverse Osmosis is Inefficient While residential reverse osmosis systems provide you with water that is far superior in quality to tap, the way that you obtain this is at best a very inefficient process. For every gallon of viable water produced by R.O, two to three gallons are disposed of. In addition, the average R.O. system takes an hour to produce a gallon or less in the storage tank. This is far from environmentally friendly, and is economically wasteful as well. Truth #3: Reverse Osmosis is Expensive R.O. systems whether residential or otherwise are simply not cost effective. Without taking into account the cost of such a system, which seems worthwhile when considering the benefits of safer water, the cost to produce clean water with these units is simply expensive. For every gallon produced by these units, the owner can expect to pay on average about twenty to twenty-five cents. While far cheaper than bottled water, there are more effective, cost-efficient, and beneficial systems on the market. Summary: Reverse Osmosis is Better Than Tap, but Not Your Best Option There are filtering systems available now called multi-stage water filtering systems. Available to install on countertops, under counters, and even in showers, these systems use the most effective methods to remove all contaminants while leaving in valuable minerals.
