If your building has no central softener, an apartment water softener installed at your own water inlet protects everything inside your home: the combi boiler, water heater, taps, shower screens, washing machine, dishwasher and coffee machine. Modern cabinet units combine the resin tank and the salt tank in one compact body that fits in a kitchen cupboard or bathroom.
Signs You Need One
- White marks on taps, glass and shower screens soon after cleaning.
- The boiler or water heater makes noise and heats more slowly.
- Washing machine and dishwasher need frequent descaling; laundry feels stiff.
- Kettle and coffee machine scale up within weeks.
Cabinet Softener or Filter?
A polyphosphate limescale filter in front of one appliance is cheap but does not soften water. A cabinet softener removes hardness for the whole apartment. Compare the technologies on limescale treatment systems.
Choosing the Size
| Household | Typical resin | Example model |
|---|---|---|
| 1–2 people, 1 bathroom | 8–15 L | Mini cabinet |
| 3–4 people, 1–2 bathrooms | 15–25 L | Maxi cabinet with digital valve |
| 5+ people, 2+ bathrooms | 25–30 L | Maxi cabinet or tank-type unit |
Very hard water (above about 35 °fH) needs a larger resin volume for the same household. See our water softener models, such as the AQUA BELLA Soft Plus Mini and the Neva Maxi cabinet softener.
Installation
- Fit after your apartment’s main valve, with a bypass.
- Connect the regeneration drain to a sink trap or floor drain.
- Plug into a standard socket; set hardness and regeneration time.
- Fill the cabinet with tablet salt.
Most plumbers complete the job in a few hours. We send installation instructions and support your plumber by WhatsApp.
Maintenance
Add salt when it runs low, check outlet hardness occasionally with a test kit, and clean the brine tank once a year. See also water softening systems.
Price
Cabinet softeners start at a few hundred US dollars; see water softener prices. If your whole building is affected, a central apartment block softener may be more economical.
