Why use Reverse Osmosis?
Reverse Osmosis is considered one of the most all-around effective filtration methods. Utilizing semi-permeable membranes with holes just 0.001 microns in size, reverse osmosis filters are even able to remove dissolved solids from the water. This means that the reverse osmosis membrane can trap many types of contaminants that standard sediment or carbon filters cannot. Contaminants such as nitrates, arsenic, fluoride, and chromium are examples of contaminants where traditional filtration can fall short. Reverse osmosis filtration on the other hand can remove up to 99% of over 1000 contaminants. If you are concerned about the amount of total dissolved solids in your water, or are looking to reduce a particular chemical in your water, Reverse Osmosis is most likely the best filtration option for you.
