Vertex EasyPur 5-Stage Reverse Osmosis Water Purification System Replacement 75 GPD RO Membrane 75 GPD, TFC@65 PSI Pressure Differential - Reverse Osmosis filtration cleans water by taking out the totally dissolved solids (TDS) which contaminate the water. Although city water treatment removes the dirt and debris and adds chlorine to prevent the spread of diseases, it does not remove the dissolved solids from the water. And with the increasing pollution of our surface and groundwater with contaminants such as lead, mercury, and chromium-6, as well as the naturally occurring harmful contaminants such as arsenic, fluorides, and sulfides found in some areas of the country, it is more important than ever to have a way to remove these contaminants at the point of use. For use in the Vertex EZ-575 PureWaterMachine RO System **Recommended to replace every 2 years.
