3. Product Overview and Components
The Nexus Water Ionizer Filter is designed to remove impurities from your water, ensuring clean and healthy drinking water. It consists of the main filter cartridge and may require a plate adapter for installation, depending on your specific ionizer model.
Plate Adapter Information:
The plate adapter for Nexus ionizers is often an integral part of the filter. When replacing the filter, it is crucial to remove the plate adapter from the old filter and insert it into the new filter. Failure to do so may prevent proper attachment of the new filter due to size discrepancies. Plate adapters can also be purchased separately if needed.
