Don’t let anyone tell you that you need a reverse osmosis water filter. There are so many better options today, that the reverse osmosis filter is practically obsolete, at least in the home.

Wastewater treatment facilities should use a reverse osmosis water filter, as should public drinking-water treatment facilities. There are many industrial applications for a reverse osmosis filter, but for home purification, the step is expensive and mostly unnecessary.

Take, for example, an under the counter system designed to purify publicly treated waters. If the system includes a reverse osmosis filter, as well as the necessary steps to remove chemical contaminants, such as chlorine and its byproduct THM, your cost will be around $800.

You can do the same thing for less than $200. An adsorptive carbon block, with a submicron porous structure and an ion exchange step will remove chlorine, THMs, cysts, lead and hundreds of other cancer-causing chemical contaminants, but is still affordable.

Those who recommend RO have some ulterior motive. Either they are salesmen or affiliates of the companies that sell the home systems. At one time, it was the best solution for people with private wells or heavily polluted sources.

But, the truly effective systems cost around $10,000. The cheaper models available from companies like GE and Ever-pure cannot be used by someone with a heavily contaminated source. They were designed for those of us serviced by a public utility.

Obviously, there are problems with publicly treated water. The chlorine levels are dangerously high, because the level of bacteria in our sources continues to grow. Whenever chlorine is used for disinfection, cancer-causing THMs are released.

Public facilities cannot remove cysts, which get into our supplies from farm run-off and in other ways. Chlorinated water eats away at lead-lined pipes, causing further contamination. Industrial pollutants have turned the groundwater into a carcinogen.

But, will a reverse osmosis water filter address all of these issues? The answer is “no”. A reverse osmosis filter only reduces lead to the “federal action level”. That means there are still traces of lead left behind.

A reverse osmosis water filter, alone, removes no chemical contaminants or anything smaller than the size of its pores. About the only thing that it will do is remove cysts and any purifier certified to filter down to “one micron” will remove cysts.

The least expensive purifiers on the market remove cysts. It isn’t a difficult thing to do.

A reverse osmosis filter is prone to tear and break down. They require electricity to operate efficiently and a separate drainage system to allow for the removal of wastewater. They may flush wastewater automatically or require hand flushing by the consumer. Either way, you are basically wasting water.

The $200 system above filters all of your waters, requires no back flushing or electricity. Maintenance is limited to a replacement cartridge, every three months of so. Consider all of your options before you buy a reverse osmosis water filter. It is simply the smart thing to do.
