Sunluway replacement mineral cartridge for Zodiac DuoClear/Fusion 35 & 25 vessels — W28001, ceramic mineral core for pools 5,000–3

Sunluway W28001 is a direct replacement mineral cartridge for Nature2/DuoClear Fusion systems, designed to fit Zodiac DuoClear/Fusion 25 & 35 vessels and treat pools from 5,000 to 35,000 gallons.

This replacement cartridge is engineered to work with DuoClear, Fusion and Nature2-style mineral dispensers in compatible Zodiac pool vessels (excluding Limited models). It uses a ceramic-particle mineral core housed in a durable plastic shell to integrate with your existing filtration equipment and help maintain clear, debris-reduced pool water between routine chemical treatments. The part crosses with W28000, W26000, W26001 and 50001800, making it a straightforward swap for many legacy cartridges.

How does this cartridge integrate with my Zodiac DuoClear or Fusion system?

The Sunluway W28001 is sized and shaped to replace Nature2/DuoClear mineral cartridges in compatible Zodiac vessels. Installation is tool-free and meant to slot into the same dispenser housing as the OEM cartridge, so it pairs with your current filtration flow and circulation patterns without modification.

What materials and technology are used inside the cartridge?

• Manufactured to fit existing dispenser dimensions and flow rates.

How easy is it to install and maintain this mineral cartridge?

• Tool-free swap—most replacements take only minutes.
• Recommended replacement interval: about six months for consistent activity.
• Low routine maintenance; inspect seals and housing during each change.

• Designed for pools between 5,000 and 35,000 gallons.
• Fits above-ground and in-ground vessels within the stated compatibility.
• Functions as part of the dispenser and filtration routine, not a standalone sanitizer.
