Replacement for Nature2 Duoclear 25 Mineral Cartridge W28000 - Fits

Our review of the Replacement for Nature2 Duoclear 25 Mineral Cartridge finds it to be a no-nonsense, budget-friendly swap for owners of Zodiac DuoClear and Fusion systems. It is best for pool owners who need a direct OEM-compatible replacement that restores mineral-treatment performance for pools up to 35,000 gallons, without extra fuss. The biggest reason to buy is simple compatibility and ease of installation: this cartridge fits the same vessels as W28000/W26000 and gets a tired mineral system back to work with minimal effort.

Key Features

• Compatibility: Works with DuoClear 25, Fusion 25, Fusion Soft and Vision Pro vessels so it replaces original W28000/W26000 parts.
• Capacity: Designed to treat pools up to 35,000 gallons, making it suitable for many medium and larger residential pools.
• Material construction: Made with ceramic media and a premium PVC housing for corrosion resistance and impact durability in wet pool equipment environments.
• Filtration pores: Tight pores capture debris such as leaves, sand and hair while helping keep water clear and balanced with the mineral media in place.
• DIY installation: No tools required to replace the cartridge, so routine swaps are quick and straightforward for homeowners.
• Warranty support: Backed by a 30-day money-back guarantee and a 12-month warranty for quality-related issues.

Who It's For

This cartridge is aimed at pool owners who already use a Zodiac DuoClear or Fusion-style mineral system and want a direct replacement without modifying plumbing or vessels. It is particularly well suited for users who value simple maintenance, straightforward fit compatibility, and a low-cost alternative to OEM cartridges.

Those who should look elsewhere include owners of limited-series DuoClear vessels not listed as compatible and anyone needing an integrated chemical feeder or automated control features; this part replaces the mineral media cartridge only and does not add electronic controls.
