AMI RO Membranes Made in USA


AMI RO Membranes UF Membranes NF Membranes Seawater Membranes Replacement Membranes
AMI 2.5" x 40" Nanofiltration Membrane Element 

90% Rejection NF Membrane Element 

AMI 2.5 x 40 Nanofiltration Membrane produces 600 gallons per day at 90% rejection and fits a standard 2.5-inch by 40-inch membrane housing. AMI NF9 spiral wound nanofiltration membranes provide high productivity performance while removing a high percentage of salts, nitrate, iron and organic compounds such as pesticides, herbicides and THM precursors. The low net driving pressure of the NF9 membrane allows the removal of these compounds at low operating pressures.

AMI Membranes are Made in the USA in their ISO 9001:2015 Certified Facility and are 100% Quality and Performance Tested.
