Water Filter Replacement Cartridge Pack to Suit the Undersink Bacteria/Rain/Tank Water Filter System (GT1-46WUFC)

Note: This replacement pack supersedes the previous replacement pack which featured the Yellow UFC 0.1 Micron Cartridge and 5 Micron Inline Sediment Filter. It has all the same functionality with the convenience of one less cartridge to buy, as it still filters out sediment, whilst also filtering down to 0.1 of a micron for parasite protection. Silver impregnated carbon also stands up better against biofouling from raw water sources, as compared to plain carbon alone.

Kit Contains

  1. 0.1 Micron 3-In-1 Sediment, Chemical + Bacteria Reduction Water Filter Cartridge (Replace every 6-12 Months)
  2. 5 Micron Bacteriostatic/Silver Impregnated Coconut Carbon Block Water Filter Cartridge (Replace every 6-12 Months)

Disclaimer: Do not use with microbiologically unsafe water or water of unknown quality without adequate disinfection. We recommend dosing your tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser to ensure full protection against microbiological contamination in your pipework and filter system, and to help prevent biofouling within the filter.
