## Long description

Replacement cartridge BWT Aqualizer Home in aubergine finish is designed for domestic water softening in systems compatible with 1MMW. The cartridge uses ion-exchange media to reduce water hardness, helping to limit scale formation in pipes and household appliances while improving the feel of water for laundry, dishwashing and personal care. It is supplied as a service part to restore or maintain the soft water performance of compatible home water treatment units.
Advantages
The cartridge provides targeted hardness reduction through a compact ion-exchange bed engineered for household flow rates. Its form factor and connection profile match 1MMW-compatible systems, enabling straightforward replacement during routine maintenance. By decreasing dissolved calcium and magnesium levels, it helps extend appliance life, reduces limescale deposits on fixtures and heating elements, and can contribute to lower detergent and soap consumption.
