Sterling Water Treatment 10-Inch Granular Activated Carbon Filter Cartridge (2.5" x 10")

Improve the taste and clarity of your drinking water with the Sterling Water Treatment Granular Activated Carbon Filter Cartridge (MPN: GAC10). Constructed with premium top-grade coconut shell carbon, this 2.5" x 10" replacement filter features a wide spectrum of pore sizes to adsorb a broad range of organic contaminants, chlorine, unpleasant tastes, and foul odors. Its engineered total-flow-through design maximizes water contact time with the media for exceptionally thorough purification.

The GAC10 is a key replacement pre/post-filter for residential under-sink reverse osmosis systems, including the Sterling DWSB-TFC-50 (50 GPD RO system) and the DWSB-50-PermPump.

Key Features

Top-Grade Coconut Shell Carbon Media

Utilizes high-purity coconut shell activated carbon with a versatile pore structure, providing superior adsorption capacity for chlorine, taste, odor, and dissolved organics compared to standard coal-based carbons.

Total Flow-Through Design

Designed for full-length media contact, ensuring maximum dwell time between incoming water and the carbon bed for optimal chemical and odor reduction at flow rates up to 2.5 GPM.

10-Micron Nominal Filtration

Delivers effective 10-micron filtration to capture particulate matter while polishing drinking water for crisp, clean taste.

Individually Factory Wrapped

Every cartridge is individually shrink-wrapped to preserve carbon freshness, prevent pre-installation contamination, and guarantee media integrity.

System Compatibility & Maintenance Bundles

The GAC10 cartridge is commonly paired with complementary filtration stages in multi-stage setups, including:

• PB1005 Poly Bonded Sediment Cartridge (2.5" x 10", 5 Micron)
• CB1005 Carbon Block Cartridge (2.5" x 10", 5 Micron)
• RO-TFC50 Universal R.O. Membrane (50 GPD)—typically replaced every 24 months (View RO Membrane)

For complete system maintenance, replace all standard cartridges at the same time using the Sterling ROCP-B Replacement Filter Bundle, designed specifically for DWSB-TFC-50 and DWSB-50-PermPump systems.

Sterling GAC10 FAQ

What RO systems use the Sterling GAC10 cartridge?

The GAC10 is designed for Sterling Water Treatment residential under-sink RO systems like the DWSB-TFC-50 and DWSB-50-PermPump, as well as any standard 10" x 2.5" filter housing sump.

Why is coconut shell carbon preferred for drinking water?

Coconut shell activated carbon contains a higher percentage of micropores compared to other carbon types. This makes it significantly more effective at trapping volatile organic compounds (VOCs), chlorine, and taste-altering impurities in drinking water.

How often should this GAC filter cartridge be replaced?

Standard GAC and carbon cartridges should be replaced every 6 to 12 months, depending on feed water quality and overall usage. You can replace all pre/post-filters simultaneously with the ROCP-B bundle.
