Home Granular Activated Carbon (GAC) Filter Cartridge: Advanced Water Filtration

For over two decades, industry experts have recognized granular activated carbon (GAC) as a cornerstone of effective point-of-use water filtration. Our Home Granular Activated Carbon Filter Cartridge is engineered to deliver superior performance, combining proven adsorption technology with robust construction for long-lasting, reliable purification of your drinking water. This cartridge is specifically designed for easy integration into standard 10-inch filter housings, making it an ideal upgrade or replacement for under-sink systems, countertop units, and refrigerator filters.

How Granular Activated Carbon (GAC) Filtration Works

Activated carbon is processed to have a vast network of microscopic pores, creating an extraordinarily high surface area—just one gram can have a surface area exceeding 500 square meters. As water passes through the cartridge, contaminants are trapped within this pore structure through a process called adsorption. Our premium GAC media is derived from select coconut shells, known for producing a high-density carbon with superior adsorption capacity compared to coal-based alternatives.

Key Product Specifications & Technical Details

Our cartridge is built to exacting standards to ensure consistent flow and maximum contaminant reduction. Below are the detailed specifications:

• Filter Media: High-Grade Coconut Shell Granular Activated Carbon (GAC)
• Cartridge Size: Standard 10" x 2.5" (Length x Outer Diameter)
• Filtration Type: Adsorption / Physical Trapping
• Recommended Maximum Operating Conditions:
  • Pressure: 125 psi (8.6 bar)
  • Temperature: 40°F - 100°F (4°C - 38°C)
• Core Material: Polypropylene (Food-Grade, BPA-Free)
• End Cap & Seal Material: Polypropylene & Silicone

Contaminant Reduction Performance

This GAC filter cartridge is effective at reducing a wide spectrum of common waterborne impurities that affect taste, odor, and aesthetic quality. Its performance is validated against industry standards. The following table outlines key contaminants it addresses:

Installation, Flow Rates & Maintenance

Designed for universal compatibility, this cartridge fits most standard 10-inch sumps using a 1/4" NPT inlet/outlet port. Installation is straightforward: depressurize the system, remove the old cartridge, insert the new one ensuring the O-ring is seated correctly, and repressurize while checking for leaks.

• Initial Flow Rate: Approximately 0.75 - 1.0 gallons per minute (GPM) at 60 psi.
• Recommended Service Life: Up to 6 months or 500 gallons, whichever comes first. Service life is highly dependent on incoming water quality and usage.
• Maintenance Indicator: A noticeable decrease in water pressure or a change in taste/odor typically signals the need for replacement.

Material Safety & Environmental Considerations

We prioritize safety and sustainability. The cartridge housing and core are constructed from FDA-compliant, food-grade polypropylene. The granular activated carbon media is 100% natural and derived from renewable coconut shells. At the end of its service life, the plastic components are recyclable where facilities exist, and the spent carbon is inert and safe for disposal.
