  1. Unscrew the top cap of the refillable cartridge using the included wrench or by hand if finger-tight design allows
  2. Fill the housing with your chosen media (granular activated carbon, catalytic carbon, KDF-55, bone char, or custom blend), leaving 1 inch of headspace at the top to prevent overflow
  3. Replace the top cap and hand-tighten securely, ensuring the o-ring is properly seated to prevent bypass

  5. Replace or refill media every 6-12 months depending on water quality and contaminant load
COMPATIBILITY

System Fit

This 20" x 2.5" refillable cartridge fits all standard whole house, commercial, and point-of-entry filter housings designed for 20-inch cartridges. Compatible with brands including Pentek, Culligan, GE, Hydronix, Watts, and Aquaboon. Ideal for DIY water treatment projects, custom fluoride removal systems, or specialty filtration applications where pre-filled cartridges are not available or cost-effective.

🔧 Pro Tip: When filling with granular media, tap the cartridge gently on a hard surface every few scoops to settle the media and eliminate air pockets. This maximizes capacity and prevents channeling during filtration.
