Product Description

Size: 50 Tablets

Product Description

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.

These do what they're supposed to do. Before I give a review, I'll quote the box on a few points.
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.

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 (or other chemical treatments)-

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".

UPDATE: As soon as I contacted the seller, they apologized and issued an immediate refund.
Comments: Received this product from Mario's Discount Deals. The packages looked really OLD. My product was manufactured April 1999 and it has a shelf life of 4 years which means it has been expired for 9+years now. See this website to determine if your product is EXPIRED. [...] This is what the website says.... What is the shelf life of Potable Aqua® Tablets?
Unopened bottles of Potable Aqua tablets, when maintained under controlled temperatures between 60 and 86 °F (15 to 30 °C), should remain effective up to four years. Exposure to heat, humidity, moisture, and air will reduce the effectiveness of the tablets. We recommend that an opened bottle not be kept for more than one year. Keep the cap tightly sealed.

Although this product is not required to have an expiration date, an explanation of the lot numbering system is provided for your convenience. This lot number is imprinted on the label of the bottle. Example:
4 03 27
The lot number is a five or six digit number. The first digit(s) represent the month of manufacture. The next two digits represent a two-digit year and the last digits represent a batch number for that month and year. Using the example above, the product was manufactured the 4th month of the year 2003 and was the 27th batch of product made. Under normal storage conditions, this product would be effective for at least four years for an unopened bottle and one year for an opened bottle.

If in the field, check the tablets appearance to determine if they are still effective. If the tablets are gray or dark brown in color, they are still likely to be effective. If they are light green or yellow, it means they are probably no longer effective. The tablets are very sensitive to moisture. Take care that moisture does not get inside the Potable Aqua bottle.
