  • Filter assembly having an outer filter element and an inner filter element removably installed within the outer filter element
    Patent number: 11697945
    Abstract: A filter assembly for filtering water in spas, swimming pools, hot tubs and whirlpools, having a first or outer filter element, a second or inner filter element removably installed within the outer filter element, a first coupling member associated with the outer filter element, a second coupling member associated with the inner filter element, the first and second coupling members engaging one another to connect the inner filter element with the outer filter element, and a releasable detent arrangement resisting disengagement of the first and second coupling members from one another. The outer filter element includes a filter medium for mechanically removing particulates from a fluid to be treated and the inner filter element includes a filter medium containing fluid purifying particles.

  • Glue beaded media for pool and spa filter cartridges
    Patent number: 10918979
    Abstract: A water filter cartridge includes a top end cap, a bottom end cap, a central support core and a pleated filter medium surrounding the central support core. The pleated filter medium includes glue beads formed on one or both of the outer surface and the inner surface of the pleated filter medium. The glue beads on the outer surface may be offset from the glue beads on the inner surface. The beads form ribs between the folds of adjacent pleats, which help maintain a rigid spacing between adjacent pleats of the filter medium and minimize the filter medium collapsing under water pressure when in use in a pool or spa filtering apparatus.
