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.
