Upgrade your pool filtration with the HANXER System 3 S7M120

The HANXER System 3 S7M120 combines an inner 24" filter and an outer 18" filter to deliver a combined 300 sq ft of filtration area.

Before you buy, compare the specifications with your original cartridge to ensure a precise fit and reliable performance.

Key design benefits

  • Reinforced construction with thickened filter cloth, tough end caps, and a robust internal frame enhances durability during regular use.
  • 20–30 micron high-efficiency filtration targets fine particles, helping pool water stay clearer longer.
  • NSF safety certification via IAPMO confirms components are tested for long-term water contact with no harmful substances released.

  • Backed by a six-month after-sales guarantee and dedicated technical support for peace of mind.

Care and maintenance

  • Rinse the filters with clean water regularly to remove dirt and protect the filtration media.
  • Do not backwash this filter element, as backwashing can crack components and cause damage.
  • Replace the set as needed to maintain filtration efficiency and water clarity.
