INSTALLATION & USE
How to Install the FXB10CL2
- Shut off water supply and relieve system pressure by opening a downstream faucet
- Unscrew your 10" x 4.5" Big Blue filter housing using a housing wrench
- Remove the old filter cartridge and clean the housing sump with mild soap and water
- Insert the new FXB10CL2 cartridge, check the o-ring for wear, and hand-tighten the housing back into place
- Turn water supply back on slowly and check for leaks, then flush the filter for 5 minutes before use
COMPATIBILITY
Where This Filter Fits
The FXB10CL2 is designed for standard 10 inch x 4.5 inch Big Blue filter housings used in whole-house filtration systems and well water applications. This carbon block cartridge fits any housing that accepts 10" x 4.5" replacement filters, making it compatible with most residential and light commercial installations requiring chlorine reduction and sediment filtration at the point of entry.
🔧 The FXB10CL2's exceptionally low pressure drop means you can use it as a final polishing stage in multi-stage systems without sacrificing flow rate, or pair it with a 5 micron sediment pre-filter to extend its dirt-holding capacity and maximize the 16,000 gallon lifespan.
