Nature2 Spa Cartridge

The Nature2 Cartridge purifies spa water using the natural sanitizing effect of silver. The cartridge fits into the centre of most spa filter cartridges where it will sit happily for 4 months, fighting a continuous battle against bacteria, viruses and algae.

Nature2 is compatible with the Jacuzzi ProClear system and is also a direct replacement for the Hot Spring FreshWater Ag+ Continuous Silver Ion Purifier,
