Harmsco® uses the patented dual durometer endcaps to provide superior sealing characteristics for Big Blue® and other 41⁄2” style cartridge filter housings. The overall length of the cartridge alone is 1⁄4” over standard but when installed in the housing, it is designed to compress and operate as normal.


  • Soft one-time use seals ensure a positive seal in most Big-Blue* style cartridge filter housings
  • Absolute rated one micron filter media removes cyst-sized particles for safe, cyst-free drinking water
  • Pleated microfiber filter media provides more surface area for longer filter life and increased particle removal
  • FDA listed materials for use in potable water and liquid food applications
  • End caps, center tubes and media are thermally bonded as one integral component for added strength and to provide superior end sealing
