Scalex - Salt-Free Hardness Reducer
Salt-Free Water Softeners
Product overview
Salt-free hardness reducer for household appliances
| Use | Preventing scale buildup in household appliances |
| Size | Compact |
| Water consumption for regeneration | No regeneration |
| Maintenance | Manual filter replacement |
| Number of users | 1 product for 3 people |
Scale buildup reduces the efficiency of a water heater, kettle, or any other appliance that heats water, such as a washing machine or dishwasher.
Over time, this can accelerate wear on the appliance and increase its energy consumption. Limescale deposits can also gradually reduce the performance of water-heating equipment.
The salt-free hardness reducer
- Protects your appliances from limescale deposits
- May help limit excess energy consumption caused by scale buildup
- Helps preserve the efficiency and lifespan of appliances that heat water
Benefits of this device
- Up to 20,000 L of water before filter replacement
- Contains no (poly)phosphates
- Designed to limit the effects of limescale on equipment
How does the resin work?
The resin in this filter releases a specific volume of a substance intended to prevent scale buildup.
This filter does not soften water in the way an ion-exchange resin water softener does. It acts on scale formation through three mechanisms:
- It stops the growth of limescale crystals
- It breaks the crystals down into smaller particles
- It limits their clumping
Additional filtration: the nylon mesh traps sediment larger than 100 microns, such as sand, dust, or rust.
