    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.

    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.


    • 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.

    Great backup Plan

    • Familiarity: I've used it several times

    Just like the other reviews say- these tabs make a killer water purification back up plan. Tiny tablets are easy to throw in any first aid kit. Kind of a funny taste ( what do you expect?), but better than getting sick!

    Good safety plan

    • Familiarity: I've used it several times

    I gave some of these to my parents who were heading to Asia for a month. They had a filter but I liked the comfort these gave me, knowing they had a backup plan just in case. They seem to do the job as advertised. Not a bad item to have in an emergency kit or in food storage for those times when, you know, zombies are everywhere...

    Ultra-light Insurance Plan

    • Familiarity: I've put it through the wringer

    For primary purification, I carry either a steripen or a squeeze filter for speed and ease of use. But it's always nice to have a super lightweight backup plan that weighs nothing and takes up no space. Always keep 6 or 8 of these in the emergency kit just in case.

    Scary stuff!

    • Familiarity: I returned this product before using it

    I purchased these tablets to save on some weight, so I could leave my filter at home. After reading the full multi-paragraph warning/poison/side affect section on the back, I knew there was no way I was going to ingest this. They recommend when handling these tablets you wear safety goggles & facemask!! It is harmful if swallowed, touched to skin/clothing, & can cause irreversible eye damage. Also Poisonous to aquatic life.

    Sodium Dichloroisocyanurate is NOT meant to be ingested...

    last line of defense

      I have a water filter pump and a steripen but when it comes to water quality I take as little risk as possible and having a third backup when you're out there, especially with the responsibility of others, is not only the right thing to do but also the ethical thing. Lack of potable water is a life or death situation.

      Easy Way to Safe Water

      • Familiarity: I've used it several times

      These tablets are truly an easy, great way to make your water safe. Whether traveling abroad or backpacking in the backcountry these are easy to carry along (they come in sheets with pills about the size of a baby aspirin), fairly quick to treat water, and actually taste good. Would recommend taking some along if you are headed to an area with water concerns.

      Easy and effective

      • Familiarity: I've used it several times

      Used on a 10 day trip as extra protection with a pump. MSR also states that these are ok for long term use while many are not (called tech support). Slight chlorine taste but totally acceptable. Not even sure if i could tell in a blind taste test or if it was just mental

      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.
