Product Description

Replacement Cartridge for DuoClear® Sanitizing System – 35K Gallon

Natural Mineral Sanitizer | Reduces Chlorine Use | Lasts Up to 6 Months

This DuoClear® replacement cartridge uses natural minerals to sanitize your pool while significantly reducing the need for chlorine. The 35K gallon cartridge contains silver to kill bacteria and copper to control algae, allowing you to maintain just 0.5 ppm of chlorine for complete sanitization. The result: cleaner water with less odor, reduced irritation, and a soft, silky feel.

Key Features

  • ➡️ For DuoClear® 35K gallon systems

  • ➡️ Silver ions kill bacteria; copper ions control algae

  • ➡️ Reduces chlorine use and minimizes odor/irritation

  • ➡️ Lasts up to 6 months under normal conditions

  • ➡️ Easy replacement design — no tools required

Compatibility

  • DuoClear® 35K (standard use)

  • DuoClear® 25K (cartridge lasts longer than 6 months)

  • DuoClear® 45K (cartridge lasts slightly less than 6 months)

⚠️ Important:

  • Do not use cartridge longer than 6 continuous months in standard applications.

  • Without sufficient silver residual from the cartridge, the DuoClear® system will not sanitize effectively, even at full chlorine output.

➡️ Maintain crystal-clear, silky-smooth water with the DuoClear® mineral cartridge.

I'm not sure if I need the ionizer part W28000, W28001 or 28002. All three are listed on the body of the filter (or whatever you call it) that houses the ionizer. Please advise. :)

The Zodiac DuoClear 35 Inground Cartridge (model W28001) typically lasts about six months with regular pool use and normal water conditions.
