Reverse Osmosis: What is it and why you should have one.
Reverse Osmosis is a filtration method where water is forced through a semi permeable membrane to reduce total dissolved solids and contaminants to supply fresh drinking water. A typical residential reverse osmosis system will have 3 to 5 stages of filtration consisting of a 5 micron pre-filter or Carbon block filter, Reverse Osmosis Membrane, Activated carbon post filter, In-line post carbon filter and holding tank. The pre-filter is simply designed to remove sediment and some particulates before the membrane or protect the membrane from chlorinated water supplies with a Carbon block pre-filter. The RO membrane is the primary stage of filtration and removes up to 99% of contaminants in the water. Many of these contaminants are VOC’s (Volatile Organic Chemicals) which the carbon filtration stage is designed to reduce/remove and polish the water as a final phase before delivery to the faucet or refrigerator.
