Aqualite CLASSIC HARD cartridge is specially designed for pitcher filters such as Barrier, Brita Classic, Ecosoft, and Nasha Voda used with hard water. Thanks to the increased content of ion-exchange resin, it effectively reduces calcium and magnesium salts that cause limescale formation. In addition, activated coconut carbon removes chlorine, organic impurities, and improves water taste.

Where and how it is used

The Aqualite CLASSIC HARD cartridge is installed in pitcher filters such as Barrier, Brita Classic, Ecosoft, and Nasha Voda. It is recommended for regions with high water hardness, where white deposits often appear in kettles or on dishes. It provides soft, pleasant-tasting water suitable for drinking and cooking. Perfect for daily use at home or in the office.

Maintenance

The cartridge should be replaced every 4–6 weeks or after filtering approximately 150–200 liters of water. It should not be washed or regenerated, as the ion-exchange resin gradually loses its ability to reduce hardness. For stable performance and long service life, it is recommended to use only original Aqualite cartridges, which ensure effective softening even with very hard water.
