The Disadvantages Of Reverse Osmosis Water Systems

By Tyler Waterman

Reverse osmosis water filters were the only method that was once available to provide purified water to your home. Better, more cost effective and efficient systems have since been introduced, and yet water companies still push the old system over the newer technology. There are many disadvantages to reverse osmosis systems, as we highlight below.

Who Buys Them?

There are many people that are still led to believe by those selling them that the best way to filter water coming into your home is with a reverse osmosis filter system.

These systems are disproportionately expensive, starting in the region of $10,000 to supply and fit, let alone the annual running and maintenance costs. When there are systems a tenth of the price that will do a better job and have vastly reduced maintenance costs, how are people still persuaded to buy them? The answer lies in the big marketing bucks available to push this outdated product. These units cost a lot to purchase and install, making profits to large water companies lending their weight to them great; well worth their outlay financially to market hard.

Unnecessary Waste

One of the major disadvantages of reverse osmosis systems is the huge amount of waste-water that is flushed down the drain in order to produce a small amount of purified water.

Many using a septic system for their waste water have to upgrade to larger sizes because the tank couldn't cope with the amount of waste-water it was accumulating. For example, between 40 to 90 gallons of waste-water is produced in order to give the householder just 5 gallons of purified drinking water. This is an unnecessary and flagrant waste of a precious commodity.

Power

Quite apart from the environmental impact of increased power usage, as a lot of power is necessary to produce this small amount of drinking water, the constantly rising cost of electricity ensures your power bills will reach new heights.

Is Water Safer To Drink When You Use A Reverse Osmosis System

The big question! With all this power usage and waste-water sloshing around the system, does reverse osmosis make water safe to drink?

Well, the answer is that this system makes the water safer to drink, but not necessarily safe. It does a competent job certainly, but no better than the considerably cheaper systems employing more economical methods to filter water without all the whistles and bells whilst doing so.

Other disadvantages of reverse osmosis systems are their removal of healthy minerals and failure to remove some of the harmful cysts and chemicals in the 'purified' water.

One manufacturer of such equipment has freely admitted that these units are only designed to clean up the waters aesthetic properties. They don't in fact act as a barrier against waterborne micro-biological and toxic chemicals.

Another smaller but nevertheless important of the many disadvantages of reverse osmosis filters is the removal of all the health-giving natural minerals found in water. All of these facts should point towards using a less expensive and more efficient way of providing pure water for your family. - 17269
