Replacement Carbon and Zeolite Cartridge for I25 Marine Filter

The Marina i25 replacement feed cartridge is made specifically to fit inside the Marina i25 internal filter. Its unique design forces water to enter through the center of the cartridge. As unfiltered water enters the two-chamber cartridge, it first passes through the zeolite chamber, which removes toxic ammonia. The water then enters the activated carbon chamber, where contaminants and odors are removed. Water then enters the floss layer, which traps dirt and debris. This unique flow of water results in crystal clear water. For best results, replace every 4 weeks. This package contains 2 energy cartridges.
