Reverse Osmosis Filter

Reverse systems are not ideal for residential use. They were originally developed for industrial and commercial usage. When reverse osmosis water filter systems were first introduced for residential use they were a huge seller. However, this was before people knew the effects of drinking water put through a reverse osmosis filter. While reverse osmosis is not the best way to filter water, certainly it is better than no filter at all, but there are many disadvantages to drinking water from a reverse osmosis filter.

As far as health concerns go, teverse osmosis water filter systems cannot filter anything that is molecularly smaller than water. Many pesticides, bacteria and chlorine are lighter than water and they are left behind in water that has gone through the membrane of a filter. Also, trace minerals that are essential for our health are stripped away from the water through a reverse osmosis water filter. This leaves us with de-mineralized water that is potential harmful to our health because of the pesticides.

Everything that is supposed to do can be done by another type of filtration and in most cases it is done better. For example, carbon filtration wastes, it wastes no time and it does not filter out the minerals from the water, while at the same time filtering out synthetic and harmful chemicals and improving the taste and smell. Ultraviolet radiation treatment kills all of the bacteria and other microorganisms from the water that reverse would miss. Ion exchange filtration can soften water and remove lead at a higher rate than a reverse filter.
