High-Performance Reverse Osmosis Membranes
Advanced filtration technology that removes up to 99% of dissolved solids, contaminants, and impurities from your water supply
Reverse osmosis is a technique that uses pressure to drive water through specialized membranes to remove foreign pollutants, solid particles, large molecules, and minerals. Our replacement membranes are compatible with leading RO systems from Pentair, Clack-Microline, CSM, Axeon, and other trusted manufacturers, ensuring you maintain peak system performance.
Why Choose RO Membranes
Superior Filtration Technology
Ultra-Pure Water
Reverse osmosis membranes provide the highest level of filtration available for residential and light commercial applications, removing dissolved solids, heavy metals, fluoride, arsenic, and hundreds of other contaminants that other filters cannot capture.
Thin Film Composite
Our TFC membranes feature advanced polyamide layers that deliver exceptional rejection rates while maintaining consistent flow rates. This proven technology provides superior chlorine tolerance and longer service life compared to traditional cellulose acetate membranes.
Universal Compatibility
Available in standard residential sizes including 1812, 2521, and specialty formats, our membranes fit most major RO systems. Whether you need a quick-change cartridge or a traditional membrane housing replacement, we stock the right solution for your system.
Installation Process
How to Replace Your RO Membrane
Prepare Your System
Turn off the water supply to your RO system and close the storage tank valve. Relieve system pressure by opening the faucet, then disconnect the tubing from the membrane housing using the quick-connect fittings or wrench provided with your system.
Remove Old Membrane
Unscrew the membrane housing cap and carefully slide out the old membrane. Note the direction of the brine seal and O-rings. Inspect the housing for any sediment buildup or damage, and clean thoroughly with fresh water before installing the new membrane.
Install and Flush
Insert the new membrane with the brine seal facing the correct direction as indicated on the housing. Reassemble the housing, reconnect all tubing, and slowly turn on the water supply. Flush the new membrane for 2-3 hours or until the water runs clear before normal use.
Replacement Schedule: Change your RO membrane every 2-3 years for residential use, or sooner if you notice decreased water production or quality. Systems processing high TDS water or heavy sediment may require more frequent membrane replacement to maintain optimal performance.
Maximum Contaminant Removal
Remove up to 99% of total dissolved solids including lead, arsenic, fluoride, nitrates, sulfates, and hundreds of other contaminants. RO membranes provide pharmaceutical-grade water quality right from your tap.
Cost-Effective Solution
Produce premium filtered water for just pennies per gallon. With proper prefilter maintenance, quality RO membranes deliver thousands of gallons of purified water before requiring replacement, making them extremely economical.
Environmentally Responsible
Eliminate the need for bottled water and reduce plastic waste. A single RO membrane can replace thousands of plastic bottles over its lifespan while providing superior water quality and convenience.
Easy Maintenance
Simple drop-in replacement design requires no special tools or technical expertise. Most homeowners can complete membrane replacement in under 30 minutes with basic hand tools and our step-by-step instructions.
