economical 60 GPD replacement reverse osmosis (RO) membrane element for under sink residential RO systems

The CSM RE1812-60 is a very popular replacement RO membrane that fits in most 60 gallon per day (60 GPD) residential reverse osmosis systems.

This thin-film composite (TFC) membrane has a minimum salt rejection rate of 96% (98% expected) based on a 200 mg/l(ppm) NaCl solution at 60 psi applied pressure and 15% recovery.

  • very economical, brand-name membrane
  • far higher rejection rates, greater durability and life as compared to cellulose (CTA) membranes
  • high pH range tolerance
  • shipped dry for convenient handling and long shelf-life
  • NSF/ANSI Standard 58 listed
  • best price guarantee

CSM RE1812-60 residential RO membrane elements fit most standard nominal 2-inch I.D. pressure vessels. Accordingly, CSM RE1812-60 membranes will fit in most residential RO membrane housings, regardless of brand! Be sure to match capacities, not just physical size to ensure proper performance. Compare measurements below to confirm.

Recommended Operating Conditions:
Maximum Operating Temperature:113F (45C)
Maximum Operating Pressure:150 psi (10 bar)
pH Range, Continuous Operation:2-11*
Maximum Feed Silt Density Index (SDI):5
Free Chlorine Tolerance:< 0.1 ppm**

*Maximum temperature for continuous operation above pH 10 is 95F (35C).

**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, we recommend removing residual free chlorine by pretreatment prior to membrane exposure. Most RO systems have carbon pre-filters for this purpose.

Important note about selecting the correct membrane capacity: All RO systems use a drain line flow restrictor to create pressure against the RO membrane. This pressure is critical to the performance of the RO system. If the drain line flow restrictor is not correctly matched to the capacity rating of the membrane, problems such as slow or ceased water production or high water waste can result. Select a replacement membrane that matches the capacity rating of your existing membrane and system. If you want to upgrade to a higher capacity membrane to increase the rate and quantity of daily water production, it is critical that you upgrade both the membrane AND the drain line flow restictor.

Notice: The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system.
