Product Description

Jacuzzi Earthworks DE Filter


  • Eight industry-standard curved grids, all one size. No short grid!
  • Large diameter tank allows a grid spread that covers from 15%-25% more surface area than other leading D.E. filters. This results in superior flow characteristics and virtually eliminates D.E. bridging for longer filter cycles and less maintenance.
  • D.E. is easily washed off the grids with a garden hose without disassembling or removing grid cassette from the tank.
  • GridLok design with quick release feature locks top manifold in place, but allows instant removal when unlocked.
  • Exclusive D.E.-Fence rubber bushings create a flexible seal between the grids and the top manifold, virtually eliminating D.E. bypass.
  • Unique Ring-Lok™ access allows tool-free entry to all internal parts without disturbing the plumbing.
  • Built-in tooth on Ring-Lok™ allows you to easily disengage lid from tank bottom.
  • Automatic air bleed ensures 100% grid utilization.
  • Patented built-in valve is easily removed for service.
  • Exclusive "earthshake" regeneration allows you to extend the filter cycle between cleaning.
  • Convenient easy-measure D.E. scoop included with each filter.

Hello Michael, the Jacuzzi Earthworks EW72 D.E. Filter - 94081072 would be the closest to the direct replacement if you needed EW75.

Hello, the replacement Pentair Filter - 4000 Series SMBW4048 D.E Filter 48 Sq. Ft. W/ Valve - 011555 would be closer to what you used to have. Please check specs to see if this matches your current output filter.
