The FreshWater alternative to the Triflow® 321 is a fully compatible replacement.


Our replacement water filter cartridge is designed to provide broad spectrum water filtration. Two key technologies are employed in the construction of our alternative to the TF-321 filter cartridge.  There is an outer shell of FreshWater's own sub-micron porous ceramic encloses a section of extruded carbon/zeolite block. Used in combination, these two highly efficient filter media provide effective water filtration across a wide range of possible drinking water contaminants: harmful bacteria, parasites and cysts including cryptosporidium; chemicals including chlorine, pesticides and herbicides, and heavy metals including lead.


How do we manage to offer our eqivalent Triflow 321 at such a competitive price?  Because there is no middle man involved.  We make and ship our water filter cartridges direct from our own UK factory, enabling us to keep costs to a minimum and as an additional bonus, reduce the carbon footprint.
