Before I talk about the most effective GRAVITY FED WATER FILTER REPLACEMENT FILTER you SHOULD be buying – let me be completely honest about our intentions. The #1 reason we entered into the water purification biz is because we saw so many water filter manufacturers out there feeding the consumer (you guys) a load of garbage.  Yep, no joke. It’s a crap shoot as to what your water filter actually does, since the personal water filtration industry is not monitored by the EPA or anyone else. The EPA Standards set are often ignored, because water filter manufacturers know their claims will not be questioned.  Kind of deplorable what people will do to sell products…

The Consumer Deserves Better

So, Sagan Life™ has set a new standard in the water filter business and created water purification products which not only do exactly what we say they do, they have tremendous super powers – like faster hydration. The DuraFlo™ Water Purification Filter is one of two powerful water purifiers used in Sagan Life™ products. It is an awesome water “purifier” – more powerful that just a water filter. It’s used in our AquaBrick™ System and works in any gravity fed water filter system on the market. ( The other water filter is called the Journey Filter™.

Better Water Purification

The DuraFlo™ Water Purification Filter was tested and proven by independent water laboratories to remove virus, bacteria, giardia, cryptosporidium and other water – borne toxins and chemicals, providing purified drinking water from any fresh water source.

The better choice for your gravity fed replacement water filters – hands down the DuraFlo™ filter.

The DuraFlo™ Water Filter is used in the AquaBrick™ Water Purification System making this a great camping water filter or perfect emergency preparedness gear. We use it in our home to filter everyday tap water. Sagan Life™ will have a counter top pitcher soon, but not available at this writing. We put our health before our decor for the time being, as tap water has a lot going on that we do not want to drink!  

Gravity Fed Water Filters

The DuraFlo™ filter is an especially great water filter replacement for other gravity fed water filters on the market. Be sure to check out the capabilities of the water filters you are currently using. You might be surprised at the lack of testing done on these filters. A great looking gravity fed water filter is only as good as the filters inside.

Why Wait for Water ?

The slogan “why wait for water” was conceived because of the fast flow properties of the DuraFlo™.  It flows approximately 30 gallons per hour. Simply attach the DuraFlo™ to your current gravity fed counter top unit, such as Berkey®, Doulton® and AquaRain®, as shown in the video below. Fill the canister with water and allow to sit for about 15 minutes. Then watch it flow… so, why would you wait for hours and hours to fill your counter top unit?

Most Effective Water Testing

The DuraFlo™ water purifier’s “End of Life” testing was established at 550 gallons for removal of viruses, 700 gallons for removal of bacteria, giardia, and other waterborne toxins and chemicals. DuraFlo™ Water Purification Filter also removes heavy metals, such as lead, fluoride, chlorine, industrial waste, toxic chemicals and many other pollutants you don’t want to be drinking. We use our AquaBrick™ every day and avoid tap water completely, providing us perfectly clean potable water!

HYDRATE UP TO 50% FASTER. This Sagan Life™ product provides HydraDyne™ Technology to allow your body to absorb nutrients and water faster than any other water filtration product on the market today!
