Aries (AF-20-2012) 20" x 2.5" (2 lb) KDF-55-GAC Filter
Aries AF-20-2012 KDF-55/GAC Filter Cartridge
High-capacity redox media and activated carbon filtration for chlorine removal, heavy metal reduction, and bacterial control in whole house and well water systems
KDF-55 and GAC work together to extend filter life and improve water quality
Redox Filtration
KDF-55 uses oxidation-reduction chemistry to remove chlorine and reduce heavy metals like lead, mercury, and cadmium without the quick saturation of carbon alone
Bacterial Control
KDF media is bacteriostatic, controlling the growth of microorganisms within the filter bed and preventing biofilm buildup that degrades carbon performance
Extended Carbon Life
By handling chlorine and heavy metals upfront, KDF-55 allows the activated carbon to focus on taste, odor, and organic compounds without premature exhaustion
High Flow Capacity
20" x 2.5" size with 2 lb KDF-55 load delivers up to 5 GPM maximum flow and treats 22,000 gallons in municipal or well water applications
