Reverse Osmosis Water Filtering Systems Are Dinosaurs

Learn the facts about a reverse osmosis water dispenser, before you buy. There may be better options.
Reverse osmosis water filtering systems were designed for large scale industrial use. Eventually, they were modified to fit the home. There are only a few homeowners that need RO and even they may have better, less expensive and less wasteful options, today. Technology has advanced beyond RO, but some people won't let it go.
Sub-micron Filters
But, today, we have sub-micron filtration that is similar in that it removes cysts and other contaminants larger than a micron, but it is less expensive and creates no wastewater. If you install a reverse osmosis water dispenser, the device must be located near a drain.
RO Water Systems Are Wasteful & Costly
When water becomes too "thick" to pass through the membrane, it is disposed of. Depending on the model, several gallons of wastewater may be created for every gallon that is dispensed.
That wastewater ends up back at a treatment facility or in the homeowner's septic system and eventually back in the groundwater. So, from an environmental standpoint, it is a cause of further contamination.
The only places that should have reverse osmosis water filtering systems are sewage and drinking water treatment facilities. The sad thing is that a lot of them don't. It is a costly measure. Most public utilities got their city contracts, by using the least expensive and least effective processes, available.
When used in the home, there are a number of things that a reverse osmosis water dispenser will not remove. Chemicals, chlorine, byproducts of chlorination and other things lighter than, or smaller than water's molecular structure, will not be removed.
Some home reverse osmosis water filtering systems are accompanied by a carbon filtration device. Carbon does effectively remove most of those chemicals. But, other media is necessary to remove all of them.
Chlorine byproducts, for example, can only be removed through adsorption. The chemicals are gaseous, so they pass right through a reverse osmosis water dispenser and some of them cause cancer.
Best In-Home Water Filter System
The best device for homeowners is one that contains multiple steps and filters to remove the widest range of contaminants. There are relatively inexpensive. They can be installed under or on top of the kitchen counter, in the bathroom, on the shower or the whole house.
Reverse osmosis water filtering systems take up a great deal of space. The larger units are the most effective. They use electricity. They require extensive maintenance and the membranes themselves can become contaminated with bacteria and algae. Chlorine will kill the bacteria and algae, but it also damages the membrane.
Replacement membranes are expensive. Installation is expensive. Power and water bills go up. There just is no advantage to a reverse osmosis water dispenser in light of today's technology. Make the right choice for your family and the environment.
