Growonix KDF85 Carbon Filter for Slim Scrubber - 2.5 x 20-in - Catalytic Carbon

Cleaner Source Water for Your Reservoir - 2.5 x 20-in Replacement Cartridge

Chlorine and chloramine in tap water can disrupt a hydroponic system, and a spent filter lets them through. This replacement cartridge uses KDF85 catalytic carbon to treat water before it reaches your reservoir. The distributor rates it for 17,000 total gallons of chlorine or chloramine removal.

This single cartridge suits growers who run a compatible filtration unit and need a straightforward swap when the media is spent. It fits home setups and small commercial rooms that already use these systems.
