Smart Tip: To save time and money, use dual or triple housings for waters with heavy loading. Multiple housings will significantly increase cartridge life by preventing premature fouling and will reduce cartridge change-out frequency.

For example:
  • 1. Water with light sediments and organics use dual (2) housings with 1 x sediment and 1 x carbon cartridge
  • 2. Water with heavy sediment and organics use triple (3) housings with 1 x coarse sediment, 1 x fine sediment and 1 x carbon cartridge
