HUM Water 10” BB 75-25 Dual Gradient Sediment Filter – Part #3015155
The HUM Water 10” Big Blue 75-25 Dual Gradient Sediment Filter is designed for high-capacity whole-home water filtration with staged sediment removal. This cartridge features a coarser outer layer that captures larger particles first, followed by a finer inner layer that traps smaller debris, helping extend filter life, maintain better water flow, and protect the rest of your filtration system.
Ideal for both municipal and well water applications, especially where sand, rust, scale, silt, or turbidity are present.
Key Benefits
Dual Gradient Filtration
The 75 to 25 micron layered design captures larger sediment first, helping prevent premature clogging and extending the lifespan of the filter.
Improves System Performance
Helps protect downstream carbon filters, UV systems, water softeners, and other treatment equipment from sediment buildup.
High-Capacity Big Blue Design
Fits standard 10" x 4.5" Big Blue housings for higher flow rates and increased sediment holding capacity.
Reliable Flow and Performance
Designed to maintain strong water pressure while effectively reducing particulate matter.
