Product Overview
The Nature2 W28002 DuoClear 45K Replacement Cartridge is a key maintenance component for pool owners using the DuoClear or Fusion mineral-ion sanitation system designed for larger residential pools (up to 45,000 gallons). By integrating mineral-ion technology into the pool’s water treatment regimen, this cartridge reduces the load on traditional chlorine or salt-chlorine systems, enabling gentler water chemistry and improved swimmer comfort.

Installation is straightforward — the user removes the old cartridge from the mineral-vessel and replaces it with the W28002 unit. Because the cartridge is designed to last approximately six months, service intervals become predictable and manageable as part of routine pool maintenance. In your e-commerce catalog, this product should be categorized under “Mineral Sanitizers & Replacement Cartridges” with cross-reference to the DuoClear and Fusion systems. Highlight its capacity rating (~45,000 gallons) and compatibility with salt, chlorine, ozone or UV treated pools to attract both pool owners and service professionals.
