  • No chemicals to leach-out with new melt spinning and yarn forming process.
  • No media migration because the yarn consists of continuous filaments.
  • True graded density-new winding technology gives denser winding in inner layers and coarser winding in outer layers.
  • High dirt holding capacity and longer life as particles are trapped throughout the entire cross section of water filter.
  • Better performance – multi-lobal cross section filaments with random 3 dimensional media structure captures more particles compared to conventional water filters.
  • High bulk media having improved void to solid ration gives higher flow rates with low pressure drop.
  • 100% polypropylene – wide chemical compatibility and excellent micro-organism resistance.
  • High structural stability, i.e. no shifting of media, excellent knife-edge sealing.
