Compatible with the Premier Standard Reverse Osmosis Systems. This semi permeable membrane effectively reduces TDS and sodium as well as a wide range of contaminants such as Arsenic, Lead, Percholate, Chromium, Copper, Radium and Protozoan Cysts, such as Giardia and Cryptosporidium. The heart of your Reverse Osmosis system reducing impurities down to 1/10,000 of a micron.Applications:5SV4SVWP-5WP-4VZero Waste*Note: This membrane is not for use with the quick change reverse osmosis systems.Specifications:Water Production: 24 GPD (Gallons Per Day)Filter Rating: 2-5 Years*Easy to installFlow Restrictor: 250ml*Note: Membrane life may vary based upon local water conditions, use patterns, and frequency of filter changes.Special Note:Due to a change in technology regarding the membrane and standard RO systems. Before the invention of the in-line flow restrictor there was a enclosed flow restrictor that could not be cleaned. This flow restrictor was enclosed in a solid plastic casing and had to be changed everytime you changed the membrane. With our new in-line flow restrictor it can be removed, cleaned and replaced without haveing to purchase a new one.
