    The housesold descaler solves hard water problemswithout the need for chemicals salt or filter cartridges by leaving the minerals in the water The device does not "remove" anything from water but rearranges the molecular structure of the minerals in the water Based on this minerals will flow through the pipes without attaching to the plumbing system .9V,Waterhardness:10-12.5GPG.
  • HOW IT WORKSThe current in the circuit is transmitted to the coil which induces a magnetic field. The magnetic field sweeps the water at a pre-designed frequency. The water molecules resonate. The calcium magnesium.and carbonate ions in the water collide with each other to form a new crystal that is insoluble in water.There is no charge on the crystal surface. The crystal flowalong with the water instead of sticking to pipe walls.
  • How long does it take to make improvements:Days and weeks to months.It depends on the water composition and the amount of lime scale in the plumbing system.
  • How can I feel the improvement First of all, the soap lathers more easily and is easier to clean. It's more effective. Limescale disappears from shower heads and faucets.Limescale disappears from the kettle and hair becomes softer.
  • Note: High iron content in the water will reduce the effectiveness of the Electronic Scale Remover. For iron content in the water exceeding 0.3ppm, it is recommended that an iron removal filter be installed before use.It can be used for either PVC or copper pipes.
