The advertisements for reverse osmosis equipment sure make this system look good don't they? They would make you think that what you are looking at is the most state of the art equipment that is available, and everything that you will ever need for effective protection from the contaminants that are in our water supply. Unfortunately none of this is true.
What you are getting when you buy one of these systems is a machine that is barely capable of removing anything harmful from your water supply. You have to remember that they are designed after the large scale apparatus that the local wastewater treatment facilities have. What you have to keep in mind there is that if the machines that these facilities had could effectively clean you water, you would not be looking for a filtering system.
The reverse osmosis equipment was designed primarily for the demineralization of water, but not for purifying it. When this type of system was designed there weren't nearly the number of contaminants in our water supply, and there was certainly not the number of chemical agents present that we have today. The fact is that this type of system was designed for the problems of a bygone era.
The system works through the use of a simple, porous membrane filter, which is not designed to be effective at removing matter from the water that has an equal or lesser molecular weight than water itself. The vast majority of the chemical contaminants that are present fall into this category. These chemicals pass through the membrane filter totally unobstructed.
The reverse osmosis equipment that is designed for home use utilizes the exact same porous membrane. These systems will not allow as many of the chemical agents in our water to reach your drinking glass as the ones at the wastewater treatment facilities do, because they have what is known as an activated granular carbon filter that will block some of them out.
This filter alone however is not nearly enough to sufficiently protect your family from the thousands of contaminants that are present in our water. There are many more chemicals that activated granular carbon will not remove, as well as various microbes in the water that the chlorine disinfection process fails to remove. You need more filtering than this system provides.
Instead of wasting your money on reverse osmosis equipment you should invest in a high quality home water purification system that provides you with all of the tools that you need. In addition to activated carbon you will need a multi media filter, a sub micron filter, and an ion exchange if you want your water to truly be safe to drink.
Why would you pay an exorbitant amount of money for reverse osmosis equipment, which offers you nothing, when for as little as $125 you could have a system that takes care of all of your needs? If you want to protect the health of your family then the best place to start would be to buy a system that is truly effective.
