If you’re looking for a reverse osmosis water dispenser, one of the two primary types of home water filtration system, there are a few things you need to know.


You may already know that investigators have found some 2100 chemicals in our water, and that while most of them are present in low concentrations, many of them are known to cause cancer, and many of them are suspected to cause cancer, or otherwise be dangerous.


Reverse osmosis systems are widely sold in the U.S., but many people install carbon filtration units, which have a number of advantages. We can’t deal with all the differences here, but here are a couple of considerations:


Reverse Osmosis Water Dispenser Systems


They function by forcing water through a semi-permeable membrane. The membrane’s holes are small enough to filter out most contaminants in the water, and just large enough to let the water molecules through.


RO systems do a great job of removing sediment, salt, nitrates, and many other chemicals, cysts and bacteria, however there are a few problems with this approach.


A reverse osmosis unit also filters out the calcium, potassium, and magnesium-minerals that the human body needs, and that make the water taste good. Many authorities believe that changing the acid/alkaline balance of the water by removing all the minerals is harmful.


On the other hand, one of the things you would want removed from the water has molecules that are smaller than a water molecule, so they slide right on through the membrane. These are called “Volatile Organic Compounds”, or VOC’s.


Breakdown products of oil and gasoline; many pesticides and weed killers; many pharmaceuticals; and many household cleaning products form VOCs-not something we want in our water.


For this reason, a good reverse osmosis water dispenser unit for home use must also include carbon filtration, which does capture VOC’s. So while it’s not accurate to say that an RO unit won’t remove VOC’s, as some competitors do, it is accurate to point out that it must have an additional carbon filter to do so. In other words, in purchasing a reverse osmosis system, you must be certain not to buy one without a carbon filter.


Another issue with reverse osmosis water dispenser systems, no matter how good a job they do at removing contaminants, is that they waste a lot of water. Depending on the system, 3 to 10 gallons of water are wasted for every gallon processed.


If you are looking for a quality reverse osmosis water dispenser, I can recommend you the Taiwan-based RO manufacturer, Triwin Watertec.
