Description
This filter combines two proven filtration media to deliver consistent, high-quality water: KDF-55 Media: Specially developed for chlorine reduction and the removal of water-soluble heavy metals such as lead, mercury, and nickel. It also inhibits the growth of bacteria and algae, extending the life and effectiveness of the filter.
Granular Activated Carbon (GAC): Enhances taste and odour by adsorbing chlorine and chemical contaminants, improving overall water quality. Independently tested to NSF/ANSI Standard 42 for Aesthetic Effects, the CrystalPure® OCK300 reliably reduces chlorine by more than 90% under standard test conditions. With a capacity of up to 2,000 gallons (≈ 7,500 litres) or 3 years, this cartridge offers excellent long-term value. Key Features
