Description
DAFI Water Softening Filter 10" is an original filter cartridge for domestic flow-through installations, designed to soften tap water. Thanks to ion-exchange resin, it helps reduce water hardness, removes calcium and magnesium ions, and reduces limescale buildup in household appliances. This water filter supports everyday water treatment in a whole-house installation, while also improving water taste and eliminating the taste and smell of chlorine. The universal 10" format makes the cartridge compatible with devices designed for standard housings of this type and it can be a practical element of a water filtration system.

DAFI 10" softening cartridge for home installation
The DAFI 10" cartridge has been designed for use in flow-through filters used in domestic installations. Its main task is to reduce water hardness, which is important both for user comfort and for protecting fittings and appliances that come into contact with water.
The ion-exchange resin used in the cartridge is responsible for removing calcium and magnesium ions, which are the components responsible for limescale deposits. This solution works particularly well where tap water causes rapid buildup in kettles, coffee machines, washing machines, dishwashers, and other household appliances.
