Aqualite HARD10BB water softening cartridge is designed to reduce water hardness caused by calcium and magnesium salts. Inside is ion exchange resin that acts like a magnet — it attracts and holds hardness salts, leaving the water soft and pleasant to the touch. Softened water lathers better, prevents scale buildup, and extends the life of household appliances.

Where and how it’s used

The Aqualite HARD10BB cartridge is installed in Big Blue 10" filter housings. It is used in homes, apartments, cottages, and offices to protect boilers, washing machines, coffee makers, and filters from scale buildup. Softened water improves appliance longevity and enhances water taste.

Maintenance

The cartridge should be replaced every 3–6 months or after its capacity is reached. It cannot be regenerated or washed, as the resin gradually loses its ion exchange ability. For stable system performance, always use original Aqualite cartridges — they ensure efficient and consistent water softening.
