Watco PBJ1005-9 Poly-bonded Filter Cartridge 5 Micron

Product Description

The WATCO PBJ1005-9 is a poly-bonded sediment filter cartridge rated at 5 micron filtration, measuring 10 inches in length by 4.5 inches in diameter. Poly-bonded construction bonds polypropylene fibers together to form a rigid, gradient-density filter matrix that captures sediment, dirt, sand, rust, and scale particles. The result is a cartridge that holds its shape under flow and resists channeling better than wound string or spun alternatives. Licensed plumbers and water treatment technicians install this cartridge in standard big-blue or jumbo filter housings as part of whole-house or point-of-entry filtration systems.

This cartridge is suited for residential and light commercial water filtration applications where sediment control upstream of softeners, carbon filters, or other treatment equipment is required. At 5 micron, it removes fine particulate that would otherwise foul downstream equipment or reduce water quality. It fits standard 10-inch jumbo housings with a 4.5-inch inner diameter, making it a common replacement in pre-filtration setups on well water systems and municipal supplies with elevated sediment loads.

Key Features

• 5 micron poly-bonded construction captures fine sediment including dirt, sand, rust, and scale
• Gradient-density fiber matrix reduces channeling and extends service life
• 10 inches by 4.5 inches sizing fits standard jumbo and big-blue filter housings
• Rigid cartridge structure maintains filtration integrity under normal line pressure
• Compatible with both well water and municipal supply applications

Compatibility

Designed as a replacement sediment cartridge for standard 10-inch jumbo filter housings with a 4.5-inch diameter cartridge capacity, commonly used in residential and light commercial point-of-entry filtration systems.

Installation Notes

Installation is performed by a licensed plumber or qualified water treatment technician. Shut off the water supply and relieve system pressure before opening the filter housing. Inspect the housing sump and O-ring for wear or debris before seating the new cartridge. Follow local plumbing codes for any work performed on potable water supply lines.
