4.6: KDF-55 and KDF-85 Cartridges
KDF-55 Media is typically used to reduce chlorine and heavy metals from water supply by the Reduction Oxidation process (Redox). KDF-55 media prevents bacteria and algae growth, and controls scale; and maybe used with carbon media prolonging carbon media’s life.
KDF-85 Media is typically used to reduce hydrogen sulfide and iron from water supply by the Reduction Oxidation process (Redox). KDF-85 media prevents bacteria and algae growth, and controls scale; and maybe used with carbon media prolonging carbon media’s life.
