If you’re looking for a lightweight water purifier that won’t break the bank, then you have to check out the Grayl Ultralight Purifier Bottle ($59.50). I was super stoked when I came across this purifier on Kick Stater, and here is why.

Over the years I have purchased numerous filters/purifiers for camping and hiking but could never find one that had all the features I was looking for. Mainly, I wanted an apparatus that would:

  1. purify water, not just filter it,
  2. be lightweight,
  3. have multiple functions/uses,
  4. be easy to use, and
  5. be able to process lots of water efficiently.

Most currently available purifiers have some of these features, yet always compromise in one area to excel in another. For example, most of the really good purifiers are usually the heaviest, while the ones that are lightweight normally have a hard time processing volume efficiently. The ones that process large volume have lots of parts that can break while on the trail and can be hard to use. Lastly, very few have multiple uses.

But then I found the Grayl Ultralight. For starters, it is great at its main function…purifying water.  It can kill 99.9999% of virus, bacteria and protozoan cysts; and removes particulates, chemicals and heavy metals. It is also very light, weighing only 10.9 ounces, which is perfect for hiking since it will not weigh down your pack. Third, not only is it a purifier but the Grayl Ultralight can used to store water as well allowing you to leave your other water bottles at home. Finally, it is easy to use and can process 16oz of water in 15 seconds (2 liters per minute), allowing you to have enough fresh water for you and your hiking partner.


So why is it so easy to use? Mainly because there is no pumping or sucking involved. All you have to do is fill the outer shell with the water you’d like to drink, and then push the inner filter shell down into it, forcing the water through the filter. Since you use your own body weight to push the filter down, it is very easy and only takes 15 seconds.

The only downside to Grayl Ultralight is that it only purifies about 150 liters (40 gallons), or 300 uses. This is much less than some other purifiers but is still plenty enough to provide clean water for numerous hikes and camping adventures. However, you can buy extra replacement purifier cartridges for $24.50.

In the end, I think the Grayl is perfect for all hikers, campers, preppers or anyone looking to make an addition to their emergency gear supply stash.
