The USWF Big Blue 10-inch Heavy Duty Whole House Filter Housing is designed to accept standard 10" x 4.5" Big Blue size filter cartridges. This includes sediment, carbon block, GAC, pleated, and specialty cartridges in a wide range of micron ratings (typically 1, 5, 20, and 50 microns), giving you flexibility to customize filtration based on your home's water quality needs.

This USWF Big Blue housing features 1-inch NPT inlet and outlet ports, making it ideal for whole house applications that require higher flow rates. It supports flow rates up to approximately 20 GPM (gallons per minute), depending on the cartridge installed, and is rated for operating pressures up to 90 PSI with a temperature range of 40°F to 100°F.

Cartridge replacement for the USWF Big Blue 10-inch housing typically ranges from every 3 to 6 months, depending on the type of cartridge used and your household's water quality and usage. Sediment cartridges may need changing every 2-3 months in areas with heavy sediment, while carbon block cartridges generally last around 6 months or up to 20,000 gallons. The housing itself is built for long-term durability and only requires periodic O-ring lubrication.

The USWF Big Blue 10-inch Heavy Duty Whole House Filter Housing is constructed from FDA-compliant, food-grade materials and is manufactured to meet NSF/ANSI Standard 42 guidelines for material safety and structural integrity. The housing includes a reinforced heavy-duty cap, pressure relief button, and durable polypropylene sump designed for reliable whole house filtration performance.

The USWF Big Blue 10-inch Heavy Duty Whole House Filter Housing includes the housing sump, heavy-duty cap with 1" NPT ports, a pressure relief button, O-ring, and a housing wrench for easy cartridge changes. Installation requires mounting the housing on your main water line after the shutoff valve using the 1" NPT threaded connections. We recommend using thread sealant tape on connections and installing a mounting bracket (sold separately) for added stability. Always shut off water and depressurize the line before servicing.
