Pentek - 10" Big Blue Filter Housing - Blue Cap / Clear Sump - 1" NPT
10" Big Clear Filter Housing with 1" NPT Ports
High-capacity clear housing for sediment, carbon, and specialty filtration with visual flow monitoring and reinforced construction for residential and light commercial applications
Built for High-Flow Applications
Visual Flow Monitoring
Clear Lexan sump allows on-site inspection of cartridge condition, sediment load, and flow performance without shutting down your system
1.5" Internal Port Design
Reinforced polypropylene cap with oversized 1.5" internal ports delivers higher flow rates with minimal pressure drop across the housing
Pressure-Relief Button
Integrated pressure-relief button on inlet side safely depressurizes the housing before cartridge changes, protecting seals and extending housing life
High-Capacity Filtration
Accepts standard 10" Big Blue cartridges up to 4.5" diameter for sediment, carbon block, GAC, pleated, and specialty media applications
Reinforced Construction
Lexan sump rated to 100 PSI with Buna-N O-ring seal and stainless steel hardware resists impact, thermal stress, and chemical exposure

Works With All Standard 10" Big Blue Cartridges
This Pentek 10" Big Blue housing accepts all standard 10-inch cartridges with 4.5" maximum diameter, including Pentek DGD series sediment filters, EP series pleated cellulose, RFC carbon block, GAC-10 granular carbon, R series pleated polyester, FloPlus series, and specialty cartridges from brands like Culligan, Hydronix, Liquatec, Rusco, and others. Use for whole-house sediment pre-filtration, municipal chlorine reduction, well water treatment, industrial process water, agriculture, and commercial applications requiring visual cartridge monitoring.
Cartridge Replacement Schedule
Sediment Pre-Filters
Replace 5-20 micron sediment cartridges every 3-6 months depending on turbidity and visual sediment accumulation in clear sump
Carbon Block Filters
Replace carbon block cartridges every 6-12 months for chlorine, taste, and odor reduction or when flow rate declines noticeably
O-Ring Inspection
Inspect Buna-N O-ring annually for wear, cracking, or deformation and lubricate with food-grade silicone grease during cartridge changes
Sump Cleaning
Clean Lexan sump with mild soap and water when sediment buildup obscures visibility or during cartridge replacement to maintain clarity
Visual Monitoring
See exactly when cartridges need changing without guesswork or pressure gauges
High Flow Design
1.5" internal ports deliver the flow rates demanded by whole-house applications
Pentek Quality
Reinforced Lexan construction and precision-molded caps engineered for years of reliable service
Universal Compatibility
Works with hundreds of 10" Big Blue cartridge options for any filtration need
