The crystal clarity of D.E. with cartridge convenience

The Highest Water Clarity with the Lowest Amount of Fuss. Quad D.E.½ Filters combine the finest filtration available for the most sparkling clear water with the convenience and easy-cleaning features usually found only in a cartridge filter. Four easily accessible and removable D.E. cartridges simplify maintenance and save time.

An Eco Select Brand Product: Water flows very efficiently through Quad D.E.½ Filters allowing the use of smaller pumps or lower pump speeds to minimize energy use. And when consumers rinse cartridges rather than backwash, they can significantly reduce water use, too.


  • Four large-capacity cartridges provide maximum filter surface area for greater dirt-trapping capacity and longer periods between cleanings
  • Unique internal flow path ensures optimum filtration and backwashing efficiency
  • Chemical resistant, fiberglass reinforced polypropylene tank for exceptional strength and long life
  • Easily removable cartridge elements make maintenance fast and easy
  • Water flows through the Quad D.E.½ Filters so efficiently that your pump will use less energy
  • Protected by U.S. Patent Pending 4,995,523 , 5,190,651 , 5,753,071 and 6,036,853
