In this review the author tests the Replacement for Nature2 Duoclear 35 Mineral Cartridge W28001 W26001 and finds it best for pool owners who want a simple, low-maintenance mineral cartridge that fits existing Nature2 and Zodiac DuoClear systems. The single biggest reason to buy is compatibility: it is a direct-fit replacement for Nature2 DuoClear 35 vessels and works with Fusion, Fusion Soft and Vision Pro systems to treat pools up to 35,000 gallon without altering plumbing or electronics.

Key Features

• Perfect Fit: Designed to match W28001 and W26001 dimensions so it installs easily in all Zodiac DuoClear 35 vessels and Nature2 Fusion systems.
• Large Coverage: Treats both above ground and inground pools up to 35,000 gallon, reducing the need for frequent cartridge swaps on medium and large pools.
• Durable Construction: Made with ceramic mineral media and a premium-grade PVC housing that resists corrosion and deformation for season-long use.
• Easy Installation: No tools required; simply unscrew the cap, remove the old cartridge and drop the replacement into place for quick DIY service.
• Works with Existing Systems: Compatible with Nature2 DuoClear, Fusion and Fusion Soft systems so owners keep their current setup while improving water clarity.

Who It's For

This cartridge is for pool owners who already have a Zodiac DuoClear or Nature2 Fusion style system and want a straightforward replacement that restores mineral treatment and clarity. It suits both above ground and inground pool setups and is particularly helpful for people who prefer low-maintenance solutions that reduce additional chemicals.

It may be less useful for owners who want a cartridge that actively dispenses adjustable chlorine levels or who need a system-specific branded part stamped by the original manufacturer; customers looking for an integrated sanitizer controller or alternative active chemical dosing should consider different products.
