Rated 5 out of 5 by from Easy and Effective Used these in river water scooped straight from the source while on a walking safari in South Africa. Don't taste too bad and I never got sick, so I'm plenty satisfied with their effectiveness.

Rated 5 out of 5 by from What's Not To Like I used these for a backpacking trip across the Teton Crest! I don't know what they put in these things but they never contaminated the taste of the water and were surprisingly easy to use. We would drop the tablet in and continue hiking a little bit and then it was good to go. Simple and easy. I used one box of these for multiple trips and still have a lot more.

Rated 4 out of 5 by from Light and Easy to Use I've been chemically treating water during backpacking trips for over 40 years, in the past often with iodine. tablets. I prefer Aquatabs for two reasons: (1) The water's taste is better than that of iodine treated water; (2) The Aquatabs and their packaging together weigh almost nothing. In other words, I avoid having to carry around either a small but thick glass bottle containing iodine tablets, or containers of Aquamira drops, or a filter. One disadvantage of Aquatabs is the product's recommendation that one tiny tablet be used to purify 1 1/4 liters/quarts of water. My own water bottles, like those of most other hikers, are one liter size. So, I've used one tablet per quart. Why doesn't the manufacturer address hikers' needs better by making each tablet slightly smaller? Also, Aquatabs cost more, for the amount for water treated, than competing products. I only backpack about 21 days per year and thus find the cost of Aquatabs reasonable. People who spend much more time on the trail, such as prospective Appalachian Trail thru hikers, often use cheaper methods. Sawyer filters are popular with economy minded long distance walkers.

Rated 3 out of 5 by from Basic chlorine tabs Strong chlorine smell and taste that definitely fades after a while. Light and compact. Recommended.

Rated 5 out of 5 by from Great item to have I bought this item from our scout shop to carry and teach some younger scouts how to treat water if they ever needed to. Simple to use and easy for a younger scout to use & understand.

What is the strength in milligrams of an individual tablet? Also, how many tablets per liter are recommended for a relatively safe water source and for a more questionable source? Thanks!

Asked by: Stonebreaker
These tablets contain 8.5mg of chlorine per tablet. One tablet per liter is enough to purify questionable water sources.
