The Clack S7011 Microline sediment prefilter protects your reverse osmosis membrane from premature fouling by capturing sand, silt, dirt, and rust down to 5 microns. This is the first line of defense in your Microline CTA or BRS3 system, extending membrane life and maintaining system performance.

INSTALLATION & USE
Replacement Process
- Shut off water supply to your RO system and relieve system pressure by opening the faucet
- Unscrew the first filter housing and remove the old S7011 sediment cartridge
- Rinse the housing with clean water, insert the new S7011 filter, and hand-tighten the housing back into place
- Turn water supply back on slowly and check for leaks before returning system to normal operation
COMPATIBILITY
Cross-Reference & System Fit
The Clack S7011 Microline sediment filter is manufactured to the same specifications as the Pentek RS-21SED5 and is fully interchangeable. It fits all Clack Microline CTA and BRS3 reverse osmosis systems as the first-stage prefilter. This cartridge is designed specifically to protect thin-film composite and cellulose triacetate membranes from particulate damage.
🔧 Pro Tip: Replace this sediment filter more frequently if you have well water or notice pressure drop. Waiting too long allows particles to compact and makes cartridge removal difficult.
