The Alka-Pi Replacement Cartridge can help protect your water supply by both lowering pH levels and keeping smaller sediments from entering your water supply. This replacement cartridge ensures that your water filtration system continues to ionize these smaller sediments with the built-in oxidation cartridge. The Alka-Pi cartridge ensures your filtration system is covering all aspects of the filtration process- leaving you with the purest alkaline water supply possible. For ideal performance, it is best to ensure that your filtration system is checked regularly for cartridges that may be blocked, deteriorated or not properly positioned which can lead to malfunction or decrease in pressure within the water filtration system. The Alka-Pi alkaline filter replacement cartridge comes fully equipped with a mineralizer to assist in the breakdown process of excess sediment. Due to its fine nature, this sediment often slip through the carbon cartridges of the water filtration system, making the mineralizer and oxidation cartridge a vital step in the complete purifying process.
