The RO membrane is an artificial semi-permeable membrane with certain characteristics made to simulate a biological semi-permeable membrane and is the core building block of reverse osmosis technology.
The membrane pore size of RO membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. from water.
It has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation. Use this RO replacement filter to filter water and protect your home and health.

Product Benefits
Provides consistent, high contaminant removal rates even with high TDS water sources.
Advanced membrane technology with innovative thin-layer composite membrane design.
More consistent performance, less fouling, requiring less frequent cleaning and replacement.
100% dry stored membranes to maximise shelf life.
Membrane element size
All units of the icon are: mm (inch)
Important information
1. The water production listed in the table is an average value, and the difference between the minimum water production of a single membrane element and the nominal value does not exceed 20% of the nominal value.
2. Wet-type membrane elements have been strictly tested before leaving the factory, and use 1 .0% sodium bisulfite (10% propylene glycol antifreeze in winter) solution for storage treatment, and then vacuum packaging, the outer packaging is Cardboard box. In order to prevent the growth of microorganisms during short-term storage, transportation and system standby, it is recommended to soak the components with a protective solution (prepared with RO produced water) containing 1 .0% sodium bisulfite (food grade).
3. The RO produced water in the first hour of operation should be discharged.
4. It is forbidden to add any chemical agents that have an impact on membrane elements during storage and operation.
