Product Overview

The Nature2 Fusion / DuoClear 35 Replacement Cartridge | W28001 is a replacement mineral cartridge designed for compatible Nature2 Fusion, Nature2 Fusion Soft, and Nature2 DuoClear pool sanitizing systems.

Rated for pools up to 35,000 gallons, this cartridge uses mineral technology to help sanitize pool water while reducing the amount of chlorine needed for everyday maintenance. The cartridge releases controlled levels of minerals into the water to help fight bacteria and control algae when used with the required chlorine residual.

This replacement cartridge is ideal for seasonal maintenance and should typically be replaced every 6 months or once per pool season, depending on pool usage, water balance, and system conditions.

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.
