Replacement Cartridge for KleenWater KW431 Hot Water System Protector Compatible with Aqua-Pure AP431

The KW431 is a replacement cartridge to the AP430 system, developed by KleenWater. This water filter cartridge is compatible with the Aqua-Pure AP431 system. The active ingredient in the KW431 is phosphate, which serves to sequester or bind calcium and magnesium hardness minerals, preventing them from precipitating out of solution and building up on metallic surfaces. Additionally, phosphate forms a thin protective layer on the pipe wall or metallic surface, helping to eliminate hardness build-up and corrosion.

The KW431 cartridge is designed to meet the following specifications: a maximum pressure of 125 psi and a maximum temperature of 100 degrees Fahrenheit. The use of this replacement filter cartridge can significantly prolong the life and improve the efficiency of traditional and tankless hot water systems. It protects these systems from acidic corrosion and hard water scale, ultimately saving energy, which is both environmentally friendly and economical.

To ensure optimal performance, it is recommended to change the KW431 cartridge every 6 months. This replacement filter is compatible with the Aqua-Pure AP431 system, providing a reliable and effective solution for maintaining the quality of your water supply and the longevity of your hot water system.
