Clean Water
 Water softening resins for pre-RO system regenerable with brine (concentration of salt in water until saturation is reached). They are regenerated by leaving them immersed in brine for 12 hours, then rinsing them with water and placing them back in the refillable cartridge, which is placed in a filter before the RO system.
 We recommend regeneration once a month (for use of 70 litres of water per week). For more sustained use, we recommend regeneration every 15 days.
