The DuraFlo™ Water Filter – used in the AquaBrick™ Water Filtration System – is tested and certified to remove virus, bacteria and giardia from any non-salt water source. The water filter’s “End of Life” testing was established at 550 gallons for removal of virus and 700 gallons for removal of bacteria, giardia and 118 water borne toxins and chemicals. Sagan water filters meet or exceed United States EPA Water Quality Standards. Visit AquaVeritas.org for more information on the water filter you use.
The DuraFlo™ Water Filter Replacement works with any candlestick style water filters, such as Katadyn®, Aqua Pur®, Doulton® and the Berkey® water filter.
1. Actual Testing of the filter to Failure:
The DuraFlo filter has been through “End of Useful Life” testing which simply means the filter has been challenged every 25 gallons with a new massive dose of all the contaminants the water filter manufacturer claims the water filter will remove, such as bacteria, virus and giardia/cryptosporidium. This testing process is repeated every 25 gallons until the water filter fails to meet the EPA Water Quality Standards – hence “End of Life”.
2. DuraFlo Filter End of Life Test Results:
The DuraFlo filter was tested by an independent water laboratory until the filter failed to meet the EPA Standards for Micro water purifiers.
The EPA standards for removal of micro-organisms from water are shown in percentage reduction as well as the water quality standard of “Log reduction”
|6 log reduction||4 log reduction||3 log reduction|
The DuraFlo Filter achieved the EPA Standards for the stated number of gallons:
|700 gallons||550 Gallons||700 Gallon|
A copy of the lab report is available upon request.
3. Drink Your Swimming Pool Water:
The DuraFlo filter was tested to remove the chemicals typically found in a non-salt water, residential swimming pool. It met the established standards for removal of the chemicals for up to 500 gallons.
4. DuraFlo Filter Flow Rate:
The DuraFlo Filter flows up to 9.5 gallons per hour through a gravity fed system, or up to 45 gallons per hour as part of the AquaBrick Water Filter System.
Comparable flow rates for other gravity fed systems are about 1.75 gallons per hour, per filter.
5. The DuraFlo Filter is Extremely Durable:
The DuraFlo Filter can be:
- Stored for long periods.
You can also not over tighten the filter when installing it in the water container, which can happen with traditional “candle stick filters”.
Other types of “candle stick filters” which are typically made of carbon and/or ceramic, will crack if frozen or dropped which makes the filter unusable.
6. Storage of the DuraFlo Filter:
The DuraFlo Filter can be used and then stored for long periods of time. Simply rinse the filter off with clean water and allow it to dry.
