What’s Reverse Osmosis?
Reverse osmosis is a filtration process that is often used for water. It works by using pressure to force a solution through a membrane, retaining the solute on one side and allowing the pure solvent to pass to the other side. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied.
AMFOR® reverse osmosis membrane elements for home drinking water are the most reliable. Advanced membrane technology and automated fabrication allow these elements to keep consistent performance and suitable for long distance transportation. AMFOR home drinking water elements are rated at 50psi and will purify about 20% more water than competitive elements rated at 60psi (please see the datasheet for more information)

b Refer to Cleaning Guidelines of ANDE-AMF.
c Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, AMFOR recommends removing residual free chlorine by pretreatment prior to membrane exposure. Please refer to technical bulletin ANDE-AMF for more information.
