20x4.5 Inch Big Blue 5 Micron Sediment Water Filter Cartridge

20x4.5 Inch Big Blue 5 Micron Sediment Water Filter Cartridge

This jumbo big blue sediment filter effectively removes particles down to 5 microns, making it perfect for whole house RO systems and larger diameter housings. Ideal for filtering spring, well, and hard water—install after the pump and before water softeners for optimal performance.

Use as a pre-filter to protect UV filters, water softeners, and other systems from sediment, rust, dirt, and muck buildup. Also great for aquariums, ponds, and Koi tanks. Note: This cartridge is 4.5 inches wide, not the standard 2.5 inches—confirm size before ordering.
