Nature2 Spa Mineral Sanitizer Cartridge

The cartridge uses a mineral bed of copper and silver ions to destroy bacteria and algae. These minerals act as a continuous purification system, allowing you to significantly reduce your reliance on traditional chemical sanitizers.

No, the Nature2 cartridge is not compatible with bromine, sodium bromide, or biguanide-based chemicals. It is specifically designed to work alongside chlorine or potassium peroxymonosulfate (MPS) systems.

Under normal operating conditions, the cartridge is effective for up to four months. After that period, the mineral supply will be depleted and you will need to install a new unit to maintain water quality.

Not entirely, but it does reduce your chlorine demand by up to 80%. You will still need to maintain a small residual level of chlorine or MPS to handle organic waste, but the water will feel much softer and less harsh.

The cartridge is designed to drop directly into most standard spa filter cartridges. It measures 1.25 inches wide and 6.375 inches high, extending to 16 inches with the included extension tubes, so ensure your filter housing has adequate space.

This specific cartridge is rated for spas and hot tubs with a capacity of up to 500 gallons. If your spa exceeds this volume, it will not be able to effectively sanitize the water.
