Jacuzzi® 300-400-500 Series 52 Sq Ft Hot Tub Filter

Galaxy: $50.99 MSRP: $79.81


Galaxy carries filters that are built better and last longer to provide the best value for our customers.

  • ​The strongest reinforced highest flow PVC center cores for even distribution of stress and increased debris loading.
  • High-quality media ensures durability, cleanability, and efficient filtration performance.
  • Antimicrobial end caps – reinforced for added strength and treated to repel odor-causing bacteria and mold. Plus, their advanced formulation resists deterioration from salt pools and high levels of chlorine
  • Filter support bands are wider, for greater break-resistance and optimum flow.
  • Antimicrobial protection – when microorganisms come in contact with the treated blue filter media, they are no longer able to function, grow, or reproduce.
