Description of Potable Aqua Water Treatment Tablets
Our Potable Aqua Water Purification Tablets make questionable water bacteriologically suitable to drink. Easy to use-water is ready in 30 minutes. One 50 tablet bottle treats 25 quarts of water. Ideal for hiking, backpacking and travel. Perfect addition to your first aid or travel kit.Used worldwide by campers, hikers, militaries, emergency organizations, and anyone else who needs to drink water of questionable quality, these Portable Aqua iodine tablets will disinfect contaminated drinking water in a pinch. The tablets--which are intended for short-term or limited emergency use only--make most water bacteriologically suitable for drinking, proving effective against Giardia lamblia when used as directed. Each Potable Aqua tablet contains 20 mg of Tetraglycine Hydroperiodide (TGHP), which liberates 8 mg of titratable iodine when released into water. Within 30 minutes, the iodine will have penetrated the cell walls of the microorganisms, rendering them inactive and making the water safe to drink. Potable Aqua tablets also neutralize the iodine aftertaste and color, helping your drinking water taste better.

Customer Review: Potable Aqua Iodine tablets
Sport shop rating: 5 Stars
I have used these before and haven't had a problem. These are for my bug out bagCustomer Review: All good backpackers have these, but as the label states they are for "emergency use"
Sport shop rating: 4 Stars
The 5 most common ways backpackers/campers purify water are
1. Boil it. Obviously slow and cumbersome. If doing strenuous backpacking/canoeing each person will need to boil a big pot of water every night.
2. Natural sunlight - letting water sit in the sun for 6 hours works (need cloudless day, correct kind of clear plastic container). The World Health Organization published a study on this, but Amazon won't let me link to it.
3. Water pump - I have used MSR HyperFlow Microfilter, though there are cheaper options if you can accept it being slightly larger. In my opinion this is the best method.
4. Household chlorine bleach - the EPA and WHO give instructions on doing this. The EPA says this may not kill Cryptosporidium. I've never tried.
5. Iodine tablets -
Positives:
-Tablets are small/light for backpackers
-Only takes 30 minutes to have water ready
-No work required
Negatives:
-EPA says it is not 100% affective against Giardia and Cryptosporidium, especially if the water is cold while being treated.
-The taste is slightly bad ('metallic' is my best description).
I think a good attitude towards these tablets is "emergency use" (which is labeled on the side of the bottle, not visible in the Amazon image). No good backpacker doesn't have these, but I suggest a water pump as the planned primary method. Note: there are also iodine "neutralizer" tablets that are supposed to remove the bad taste (you drop them in after the 30 minutes is up and wait another 30 minutes). In my opinion they barely change the taste and are not worth it.
I'm only giving 4 stars since the EPA says it is not 100% effective against Giardia and Cryptosporidium. I'd give 5 stars if the product was named something like "EMERGENCY AQUA" instead of "POTABLE AQUA".
Customer Review: Good For Emergancy Kits - Recommended
Sport shop rating: 4 Stars
We bought these "Potable Aqua Water Tablets" to put in our hiking safety kit (which my wife and son have dubbed the "Zombie Apocalypse Survival Kit"), and doubles as our car emergency kit as well. The small size, effectiveness, long shelf-life, and positive reviews were the main factors for my choice.
We always keep water in our trunk and pack a good amount in when we head into the woods (we live very near the Appalachian Trail), but it is important to always be able to make questionable water drinkable (potable) or usable for cleaning wounds.
Other iodine based tablets I have tried left a funny taste that was very noticeable, but tolerable. One tip I picked up from reading the reviews here is to carry a packet of Kool-Aid or two (doesn't take up much room) to mask the taste.

Customer Review: Emergency H2O Purification, Get Some!
Sport shop rating: 4 Stars
* I'm trying different 'purification' products, until I review them all and will be posting my findings sometime this year. There are different Water Purification methods and approaches that have already been discussed on Reviews & the Forums, so I hope to be more "Region-specific", since I live in the Tropics. I'm also reviewing some Emergency Water Filtration products and I'm really interested in the Good to Excellent Filtering + Small form factor + Lightweight product lines, so if any of you have any 'real-world' recommendations, please share your info here. Thanks!Customer Review: Far too Pricy

Save your money. You can find these exact tablets in Wal-Mart cheaper and there's no shipping. Amazon should figure a way to combine shipping costs better to sell the small things like this. Unless you live a hundred miles off the beaten path, go to a major retailer and get these. On the plus side, these are excellent in an emergency kit as anticeptic for cuts. Just take a couple of tablets and dilute them in a little water and you can sterilize minor wounds.
