One of the most expensive ways to filter the water coming into your home is by purchasing and installing a reverse osmosis water filter system. However, in this case, the most expensive does not necessarily mean the best. Set out below are some of the disadvantages of reverse osmosis water purifiers.
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 The answer lies in the big marketing bucks available to push this outdated product.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.
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.
As an example, in order to produce 5 gallons of treated water, units discharge between 40 to 90 gallons of water as waste! This is bad enough, but if you are one of the thousands of people using a septic system to collect waste water from your home, then the chances are you will need to upgrade the size of your tank.
This particular system needs plenty of power in order to turn waste water into that which is drinkable. Certainly, when you take into consideration the ratio of waste water to make drinking water a lot of electricity is required and this is not only bad for your home electricity bills but for the environment as well.
Does Reverse Osmosis Make Water Safe To Drink?
The big question! With all this power usage and waste-water sloshing around the system, does reverse osmosis make water safe to drink?
There is certainly no doubt that such systems will make the water safer for one to drink than if you were to leave it untreated, but the simple answer to the question posed above is no.
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.
In fact, one manufacturer freely admits as much with a warning that these units are designed only to clean up aesthetic properties and don’t act as a barrier to waterborne microbiological and toxic chemicals.
One other disadvantage of reverse osmosis filters is that they can remove all the natural minerals which are good for us from the water. If giving your family fresh, clean, pollutant-free water as efficiently and cost effectively as possible is your aim, then you would do well to look elsewhere.
