Our take on the Duraflo Water Filter Replacement For Aquabrick Gravity Fed Water Filters 4 Filters

The DuraFlo is a replacement filter cartridge for the Sagan Life AquaBrick gravity-fed purification system. It uses a hollow-fiber and carbon block design that the maker says removes bacteria, viruses and heavy metals from non-salt water sources, and each cartridge is rated for about 700 gallons. That capacity is high for a gravity filter, so it suits households, campers and preppers who want long intervals between changes. It only fits the AquaBrick system, so it is not a universal filter and cannot be used in other gravity bags or bottles.

Questions and answers

How long does one DuraFlo filter last?
Sagan Life rates each cartridge for about 700 gallons. A household drinking a gallon a day would change it roughly every two years; a family of four closer to every six months.
Does it fit other gravity filters?
No. It is made for the AquaBrick Water Purification System only. Other gravity bags and bottles take their own cartridges.
Does it remove salt from seawater?
No. The maker states it works on non-salt water sources. Desalination needs a reverse-osmosis system.
What does it remove?
Sagan Life says it removes bacteria, viruses and heavy metals. Independent certification figures are not published, so treat those claims as the manufacturer's.
Do I need to prime a new filter?
Yes. Run water through a new cartridge and discard the first batch before drinking, as with most carbon and hollow-fiber filters.
How should I store spare filters?
Keep unused cartridges sealed and dry, away from freezing temperatures, until you install them.
