Tested and Proven Water Purification

We mean business when it comes to effective water purification. Our water filters are absolute and we stand by our test results. All Sagan Life® water filters are independently tested and proven by qualified water laboratories. The lab results are linked below for your review, so you can feel 100% confident you’re getting the quality and protection you deserve when using water purification products from Sagan Life®.

We have gone to great lengths, and frankly great expense, to have our water filters tested and certified by independent water laboratories. We have spent several years researching and testing our products to create water purifiers, we have no doubt, will keep your family safe – at home, outdoors and abroad.

The Only Effective Way to Test Water Filters

Until very recently the EPA did not enforce the water quality standards established for Microbiological Water Purifiers, such as personal filtered water bottles and small water filter devices. So, buying a good water filter was basically a free-for-all! Many companies claimed whatever they wanted in order to get you to purchase their water filtration products. Which is why we developed “End of Life” testing – the only truly effective way to prove the water filter you are using does what it says it does. Because while it may do what ‘they’ claim for the first few gallons, does it do it for as many gallons as they claim? That’s where it gets tricky. If your water filter is slated to filter thousands of gallons?!? Hmmm, how do they really know?

Be sure your water filter systems have conclusive and shared testing results.

What is “End of Life” Testing?

“End of Life” testing or “End of Useful Life” testing simply means:

  • The filter has been challenged every 25 gallons with test water which is contaminated with extremely high doses of virus, bacteria, parasites, lead and other toxic chemicals. These are all the contaminants, Sagan Life®, in this case, claims our filters will remove.
  • After running the turbid water through the filter, the scientists examine it. If the filtered water is 100% clean and pure we’re good to go again!
  • The process is then repeated adding a new mass of all the contaminants.
  • This process is repeated every 25 gallons until the water filter fails to remove the contaminants and thus fails to meet the EPA Water Quality Standards – hence “End of Life”.

So, that’s how we know EXACTLY how many gallons our filters will purify. Results are definitely on the conservative side, because in real life you will most likely never encounter such heavily polluted water as we use for test purposes.

If you’re using a water filter which claims to filter 1000’s of gallons or “works for a lifetime” or “filter lasts one year” think about that. How do they know if they haven’t done the only really conclusive test – End of Life? Make sure the water filter systems you’re using can stand up to the claims they make. Check out and see if your water filter manufacturer has done the testing.

Finally, the EPA Takes A Stand

Recently the EPA has finally started to keep an eye on personal and small water filter devices. This is great news! We were told for years the manpower was just not there. When purchasing your water filter check to see that it has an EPA Establishment Number on the label. If it doesn’t, you’ll want to keep looking…
