Product description

Minimum Rejection = 96%

Stabilized Salt Rejection: 98%

The membranes produce the rated GPD ± 20% at 60 psi. (Permeate flow and salt rejection based on the following test conditions: 250 ppm softened water source, 77°F (25°C), 15% recovery and the specified applied pressure).

Membranes must be matched with flow restrictors. Always change the flow restrictor when changing membrane size on your system.

RO Membranes should only be replaced when the rejection rate has reached less than 96% or when production slows NOT due to cold water temperature.

RO Membranes life is all determined on prefilter maintenance, tap water chemistry, and many other factors. The best way to determine when to change an RO membrane is by using a TDS meter and System Performance Chart and logging parameters which will indicate a drop in rejection.

Trying something new

I bought Filmtec membranes for decades but they are no longer available. They are crossing them to Axion. I’ve had 2 Axion membranes and both failed after 7 months. I am hopeful this SpectraPure membrane lasts at least a couple of years. Out of the bag, it performs well.

Always right always quality

I have had the same reef tank up and running for over 30 years and all but the first few I have used a spectraPure R O unit to fill it and it has done great. The people that work there have been great.

Easy filter replacement

I like shopping Spectrapure filter replacement kits to replace all the filters in my RO system at once. It’s easier than shopping individual filters.
