Reverse Osmosis - Fact vs Fiction, Volume 2


Back again today with the next installment of our myth-busting series on reverse osmosis systems.  There's a lot of bunk out there, and we're going to wade through it point by point.  As a consumer, you have a right to make an informed decision, not just having to buy-in based on some slick sales literature.  So here are the facts versus the fiction of what's out there...  Remember, if they need to back up their documentation with words like, "technically speaking...." then your guard should be up.  So here's round two:

Myth #3: RO Wastes a LOT Of Water

Myth Busted:
RO is just like a washing machine for your water. Does your dishwasher "waste" water? How about your washing machine? No - it simply uses water to clean things. In this case, an RO system uses water to produce clean water, rinsing impurities down the drain just like soil on clothes and remnants of food from your plates. Because it is able to rinse away impurities instead of having to trap them in filters, a typical RO system's filters last a LOT longer! Think about it. A filter can only hold so much. Once it is full of contaminants, it needs to be discarded. If you were able to design a filter that trapped the contaminants RO systems separate from water and rinse away, you'd need to not only buy additional filters, but also change them more often.  

Myth #4: RO Units are Not Customizable

Myth Busted:
Any filter you can add into one of the often-recommended "multi-stage filtration units" can be added into an RO system. As long as the chlorine (and iron, if you're on a well) is removed prior to the membrane, you can use any combination of filters you want. An RO is basically the same as the multi-stage system several manufacturer's seem to recommend, but with the addition of a reverse osmosis membrane. To suggest this is somehow less flexible is hogwash...
