Potable Aqua Water Treatment Tablets
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 bacteriologically suitable to drink.
For use only when drinking water is of questionable quality. Is not for use on a continuous basis. Read the complete product label and follow all directions for use.

Easy and Reliable to Use
Easy to use
Potable Aqua Water Purification Tablets are as easy as 1, 2, 3. No need to filter, stir or suck.
1) Drop 2 tablets into 1 quart or liter of water, cap loosely and wait 5 minutes.
2) Shake container to sanitize screw threads, then tighten cap.
3) Wait 30 minutes, then drink!
Note: Refer to complete product instructions for use.
Reliable Backup and Compliment to Filters
In addition to being a great stand alone purification product, Potable Aqua's small size, low price, and reliability make it the ideal backup and compliment for any filter or purification device.
In cold temperatures filter membranes and mechanisms can rupture or break without your knowledge. Potable Aqua tablets are unaffected by freeze thaw.
Bacteriological Purity at point of use
Water purified at the source can be re-infected by the container it is transported in. Potable Aqua tablets, when used as directed, help protect against recontamination in the container so your water remains bacteriologically suitable to drink at the point of use.
Bring on outdoor adventures, traveling, or just be prepared at home
Perfect to use with outdoor activities
Whether camping, canoeing, hunting or engaging in any outdoor activity, it pays to be mindful of your water supply. All Potable Aqua water purification products are lightweight, take up very little space and when used correctly will protect you from a host of bacteria and parasites.
The Center for Disease Control and Prevention (CDC) reports that between 30% and 70% of international travelers suffer some form of Traveler's Diarrhea (TD), calling TD 'the most predictable travel-related illness'. The most common causes of water-borne TD are bacteria, such as E. coli, cholera and salmonella, which are reduced or eliminated by Potable Aqua water purification products.
Be prepared for emergencies and disasters
As hurricanes and tsunamis tragically demonstrate, the first things to get knocked out by natural disasters are the electrical grid and the water supply. According to the Federal Emergency Management Agency (FEMA) an adult needs a minimum of a half-gallon of water per day just for drinking. So a family of four would require roughly two gallons per day of purified water.
Do Potable Aqua tablets have an Expiration Date?
No, Potable Aqua is an EPA registered product that does not require an Expiration date. The Lot Number that appears on the side of each bottle represents the date of manufacture of that item, not the date of expiration.
The shelf life of Potable Aqua is dependent on storage conditions. Product should be stored in a cool, dry place, in adherence with the label’s storage guidelines to maximize product shelf life. When reviewing your product, as a general rule tablets that are grayish/brown in color are good and tablets that are yellowish/green should be replaced.
Bottles that have been opened should be replaced for the next season.

Top customer reviews
1. For use only when drinking water is suspected or known to be bacteriologically substandard. Not to be used on a continuous basis. (Their website suggests a six-week limit.)
2. Unopened bottles should remain effective for four years. (Look at the bottom of this review for how to date your tablets.)
3. We recommend that you do not keep an opened bottle for more than one year.
4. 2 tablets make one quart of bacteriologically water suitable to drink.
5. Proven effective against Giarda Lamblia when used as directed.
6. Has not been shown to inactivate Cryptosporidium cysts.
In a nutshell, use according to the directions and you'll be just fine. The bottle contains 50 tablets; you use two per quart of water. In really murky water, I use three. The active ingredient is Tetraglycine Hydroperiodide 16.7% and each tablet contains 6.68% of Titratable Iodine. This is the same stuff that I used in the military, but just to be sure, I opened a bottle and got three quarts of water from the Ohio River. Murky stuff. The first quart was treated with just the Potable Aqua (2-1/2 tablets). The second quart was boiled for ten minutes. The third quart was boiled for ten minutes, then given two tablets of Potable Aqua. All water was filtered through an untreated handkerchief first to remove debris and sediment. I'll note that my measurements were three quarts before boiling, so I'm sure some of the water was lost in the last two quarts due to the boiling process. The results?
While none of the water was as good as tap water, I'm still alive. The first batch (just Potable Aqua) was okay. I remember Potable Aqua having a bad taste; so bad that they included a separate bottle of pills to add that made the taste more bearable. That other bottle is unnecessary here. The water definitely had a chemical taste, but I could drink the minimum of a gallon a day if I needed to.
The second batch (just boiling, no pills) tasted better, but smelled bad. I would be hesitant to drink any more than necessary.
The third batch (boiled, then treated with Potable Aqua) was obviously the best. Considering that boiling only took ten minutes and a metal water bottle, this is the best option. Remember that all of the water was filtered through a handkerchief first to get rid of any sediment, debris, bugs, etc.
I'll guess that if you filter the water, then boil, then use the tablets, you can use only one tablet. I'm not a doctor, dietician, or representative of the company, but I do have extensive training in SERE operations and I've been using these tablets for over fifteen years.
How can you find out when your pills were made? Each bottle has a series of numbers imprinted. For example: 403127. The first number is the month; in this case, the fourth month is April. The second and third numbers are the last two of the year; in this case, 2003. These pills were made in April of 2003. The last three numbers (127) indicate that this was the 127th batch made in that time frame. The code can be five or six numbers long; the first three numbers always denote the month and year; the last two or three always denote the batch number.
Just a friendly warning to those who decide to purchase these: Water Purification tablets are made with Iodine, therefore after you use these tablets in untreated water, it'll turn the water a light yellowish-brown color. Don't fret, because it's the natural reaction Iodine takes in water. Also your water might taste funny/weird, it's most likely the taste of the iodine if you did it correctly. I'd recommend you drop a tablet in a bottle filled with regular sink water, have a couple of sips, and get used to the taste of it before you start using it out in the field or even for emergency uses.
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 (or other chemical treatments)-
-Tablets are small/light for backpackers
-Only takes 30 minutes to have water ready
-No work required
-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".
