    Necessity for backpacking/Int. travel

    • Familiarity: I've used it once or twice and have initial impressions

    I keep these in my medical kit, just as a backup. Definitely nice to have these around if you get in a sticky situation where you need treated water! They're lightweight and take up almost no space, so why not have them around?


    • Familiarity: I've put it through the wringer

    There weren't any options of sanitized water on my recent trek to Nepal. We had to filter mountain water throughout the duration of our climb. Besides waiting 30min for it to dissolve, it worked as advertised.

    Pack your filter, but take these too

    • Familiarity: I've put it through the wringer

    I always take a filter- pump, gravity, or SteriPen but I also throw a pack of these in my pack as well. I have had each of the filters above fail for one reason or another so I don't leave home without them.

    Stay hydrated!

    • Familiarity: I've put it through the wringer

    When I'm climbing/hiking in the backcountry I always bring an MSR Trailshot filter, and these. The filter is great for getting water while on the move, a liter or two at a time; but these are perfect for once you've made camp, and want to have a few liters ready to go in the morning. Just fill up your bottles/bladders, and drop one of these in for every .75 liters, and in 30-60 minutes you've got safe drinking water ready to go. They're cheap and indispensable, and there's no reason not to have them in your kit.

    Better Safe Than Sorry!

    • Familiarity: I've used it once or twice and have initial impressions

    I purchased these tablets mainly for travel. While most countries have clean drinking water available, the water quality can be questionable in some locations. I have used these tablets while in the Backcountry and found that they are easy to use, light weight to carry, and relatively quick at treating the water you intend to drink. I also really like that this particular tablet does not cause your water to taste like pennies or a swimming pool once treated. Overall never hurts to have a few stashed in your travel kit.

    Great tablet

    • Familiarity: I've used it once or twice and have initial impressions

    I'm not one that hates the taste of iodine like most people, but with these tablets, I really couldn't even taste it at all. They're a great way to save space and have with you at all times just in case.

    Tastes better than you'd think

      Tried these out on a backpacking trip recently and was pleasantly surprised by the taste (or lack thereof). I've used other tablets in the past that definitely have stronger smell/taste. I'll use these from now on.

      They worked

      • Familiarity: I've used it several times

      I used these to supplement my Steripen (when I wasn't exactly sure of the source, or just didn't have the pen nearby) on a recent trip. I didn't get sick, so seems like they work just fine! Oh, and they taste like being at the pool, which for me wasn't a terrible thing.

      Great for treating drinking water

        Always in my pack as a backup to my Steripen. Check out the product page and FAQs:


        • Familiarity: I've used it once or twice and have initial impressions

        MSR tabs, I pretty much love them. My husband and I just returned from a trip in the Wenaha/Tucannan wilderness. Every few miles we were able to find a spring that had the most beautiful crystal clear water and I just wanted drink right from them but to be safe we added these tabs and to my surprise it taste like we were drinking right from the spring. It was brilliant. We've been using the PotableAqua Tabs only becasue we have a seemingly endless supply of them, but they have this light but always noticeable after taste/smell that just takes the allure out of drinking mountain spring water. I'll never go back. Even if we go someplace that we have to use the pump filter first, I'll still drop one of these in.

        You never know....

        • Familiarity: I've used it once or twice and have initial impressions

        Its better to be safe then sorry (or dead). I bring these along in case something weird happens. Low on weight high on life saving ability.

        Anyone know how treatment time scales with...

        Anyone know how treatment time scales with temperature.. I know the colder the water, the longer.. but at what temp do I need to start worrying about this? I lost my destructions.
