Here’s a reference chart that will help you to quickly determine the capability of the most popular Reverse Osmosis systems.
All components FDA / NSF certified. All components meet FDA food grade materials standards, and/or NSF and California performance standards where applicable.
Where Do You Begin?
If you are new to Reverse Osmosis Systems, and not sure where to start, the first thing to consider is your water source. Do you get your water from a municipal town or City water supply, or do you own a private well?
If your water comes from a municipal water treatment plant, most likely the water has been filtered free of particulates like dirt, silt, and other similar contaminates. It’s also likely that most or all bacteria has been killed by chlorination chemicals, as very few municipalities use chemical-free UV treatment to kill bacteria. However, these dead parasites, and the harmful chemicals they used to kill them are still the water. You may wish to chose from the RO systems that have a three-filter system – a single carbon pre-filter, an RO filter, and a carbon post-filter.
If, however, you own your own private well, you may want to consider adding a whole-house sediment filter to your incoming water line that will clean the water of large particulates. You could then add a three-filter system to be dedicated to your drinking/cooking/refrigerator/ice maker water. Another option would be to purchase an RO system that has the sediment filter built into it. You may even want both the whole-house sediment filter, plus the RO system with the sediment filter included, as an added protection for your RO membrane.
If you own a well, your incoming water is more apt to have live bacteria and viruses in it. Although even a good RO system can greatly reduce the quantity of this type of contamination, it may not eliminate it completely. You may also want to consider whether to choose an RO system that also has UV Light Treatment. UV light treatment of the water floods bacteria and viruses with ultraviolet light, effectively killing them, or rendering them inert, without adding any harmful chemicals to your water! It’s a great, inexpensive way to protect yourself and family.
