Benefits
The Nature2 W28001 cartridge helps keep pool water clean, clear, and comfortable by adding mineral-assisted sanitation to compatible Nature2 systems. When used with the required chlorine residual, the cartridge helps fight bacteria and control algae while reducing the amount of traditional chlorine needed.
Replacing the cartridge on schedule helps maintain consistent mineral output and proper system performance. If the cartridge is expired, mineral output may drop, reducing the system’s ability to support sanitation and water clarity.
For pool owners using a Nature2 Fusion or DuoClear system, the W28001 is the correct 35,000-gallon replacement cartridge for ongoing seasonal maintenance.
