Reverse osmosis water units are one choice for homes and public facilities, as well as some industries. But, some companies are choosing to replace their old reverse osmosis systems, with an ion exchange filter that can perform many of the same functions.
In the home reverse osmosis water units may not be the best choice for your family. Here you can read about some of the disadvantages. Company websites cover the advantages pretty extensively, so I won't go into that. I just thought that some of you might want a different viewpoint.
So, you've made a decision to purify your tap water or maybe that of your whole house. That's a great decision and will provide numerous benefits to your family's health. I'm sure that you want the best for your family, so price might not be a factor.
But, for the more budget minded individual, I'll note briefly that reverse osmosis systems cost more than any other purification system on the market, at least twice as much and usually more for a truly effective product. You have to decide if it's worth it.
It all depends on what contaminants are in your source. If you are serviced by a public treatment facility, most include reverse osmosis systems as one step in their cleaning process.
Likewise, reverse osmosis water units only perform one step in the home. Facilities that use it, also use several sediment filters, an activated carbon filter to remove those chemicals not removed by the reverse osmosis systems, a UV lamp to remove microbes that pass through the membrane and then chlorine is typically added to prevent algae growth and bacterial contamination in the pipes and complete the disinfection process.
People who live in rural areas, far away from the city's pipelines, may choose reverse osmosis water units to clean river or ocean waters, but additional steps are also necessary. Some companies have added some of those steps, such as carbon filtration. Others, such as UV light disinfection, can be added for an additional fee.
The thing to remember is that if you are serviced by a public treatment facility, you do not need reverse osmosis water units. It would be redundant, because the facilities use that step. Most people with wells and springs do not need them, because the contaminants in their supplies cannot be removed by them. You need testing to be sure, but usually there are better options .
So, in the majority of homes around the world it is an unnecessary and impractical step. Unnecessary because it does not address problems such as chemical contamination and impractical because of wastewater created, additional cost and additional energy used.
Pesticides, herbicides, prescription and over the counter drugs, hormones, chlorine, chlorine by-products, cysts and the toxic metal lead are some of the reasons that you need a home purification system. But, there are 2400 other reasons. The use of synthetic chemicals in this society might be called excessive.
And, even though the levels of these contaminants may be very low, the long term health effects of consuming those small amounts on a daily basis are unknown. In addition, researchers believe that the combination of all the different chemical contaminants increases their toxicity exponentially.
Those health threats are not removed by reverse osmosis water units. But, other less expensive purifiers will.
