75 GPD Reverse Osmosis Membrane

This is a 75 GPD (gallons per day) membrane filter. Effective in reducing TDS and sodium as well as various contaminants.
Water output: 75 GPD (gallons per day)
Minimum desalination rate - 97%
Filter rating: 2-5 years
Easy to install
If you change the flow rate of the membrane, be sure to replace the flow restrictor.

The domestic type low pressure special size TW series membrane elements are used in a variety of domestic water purifiers, hospitals, laboratory water purifiers and other small systems. Advanced membrane technology and automated manufacturing enable these elements to provide consistent performance that equipment suppliers, water treatment distributors and residential customers can rely on.
