## Summary description

Replacement water softening filter cartridge wessper WES6004 in 10" format for domestic water treatment systems. Designed to reduce water hardness and protect household appliances and plumbing by removing hardness-causing minerals. Suitable as a cartridge for inline filter housings in kitchens, utility rooms and point-of-entry installations where softened water is required.

## Long description

Replacement water softening filter cartridge wessper WES6004 in 10" format is designed for domestic water treatment systems to reduce water hardness by removing calcium and magnesium ions. Compatible with standard 10-inch inline filter housings, this cartridge helps protect household appliances, plumbing fixtures and water-using appliances from scale buildup. The cartridge is intended for point-of-entry installations, kitchen under-sink systems and utility rooms where softened water improves appliance lifetime and reduces limescale on taps and heating elements.
Advantages
The wessper 10" water softening cartridge delivers a consistent reduction of hardness-causing minerals using ion-exchange resin, providing clear flow characteristics suitable for domestic low- to medium-flow systems. It is offered in a standard 10-inch size that fits common filter housings, simplifying replacement and maintenance. By lowering mineral content, the cartridge contributes to reduced scale deposits, improved efficiency of hot-water systems and easier cleaning of sanitary fittings.
Suitable for
Domestic point-of-entry water softening for apartments and houses
Under-sink or inline softening in kitchens and utility rooms
Protection of washing machines, dishwashers and water heaters from scale
Pre-treatment before additional filtration stages or water heaters
Key specifications
Form factor: 10-inch cartridge compatible with standard inline housings
Function: ion-exchange softening to reduce water hardness (calcium and magnesium)
Material: ion-exchange resin contained in a durable cartridge casing
Flow compatibility: suitable for domestic low- to medium-flow applications
Installation position: inline / point-of-entry or under-sink use
How to use
Install the cartridge in a compatible 10-inch inline filter housing following the housing manufacturer’s instructions. Ensure water supply is turned off before replacing the cartridge, relieve pressure, then remove the housing, replace the old cartridge with the new wessper cartridge and reassemble. After installation, run water through the system for several minutes to purge any trapped air and ensure proper resin contact with the water. Monitor performance and replace the cartridge according to observed hardness reduction or the schedule recommended by the system manufacturer.
Usage recommendations
For reliable results, check incoming water hardness and flow requirements before installation. Use pre-filtration where water contains high levels of sediment to extend cartridge life. Follow local regulations and manufacturer guidelines for safe disposal of spent resin cartridges.
