Our take on the Duraflo Water Filter Replacement For Aquabrick Gravity Fed Water Filters 2 Filters

The DuraFlo is a drop-in replacement filter for Sagan Life's AquaBrick gravity-fed purifier. It is a hollow-fiber membrane cartridge rated to remove 99.9999% of bacteria, 99.99% of viruses and 99.99% of parasites including Cryptosporidium and Giardia, with each cartridge rated for up to 700 gallons. It fits the AquaBrick and other gravity-fed and countertop systems, so it suits campers, preppers and households that want stored water without power or chemicals. Against pump filters and UV bottles it needs no pumping or batteries, but it does not soften water or remove dissolved chemicals and metals the way carbon and reverse-osmosis stages do.
