4.0 out of 5 stars All good backpackers have these, but as the label states they are for "emergency use", January 6, 2010
Verified Purchase(What's this?)
This review is from: Potable Aqua Water Treatment Tablets (Kitchen)
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".

Boiling is the safest, but I think a water filter is easiest and best option.

Good food (or water) for thought. In a disaster scenerio I think we all need to get the word out about using the 2 liter water bottle solar method. GREAT POST. Now, I need to figure out what which methods (and in which priority) I'm going to use sanitize my emergency water.

Hello, I'm curious if you've come up with a plan of action for your water purification? Would you mind sharing?

BTW, I found a good post regarding the water bottle solar method, if anyone is interested: http://modernsurvivalblog.com/health/how-to-purify-water-with-sunlight/

@treehugr

I have since purchased a AquaPail 400 for me and my wife. So far I have not found a better emergency filter system for the price and portability. I also have a filter straw and iodine tablets for flexibility. To back up the AquaPail I have purchased four food grade blue 55 gal barrels and hooked them up to my rain gutters. I suppose I should start gathering 2 liter soda bottles and store them after cleansing them with some Clorox water for safe storage. Since I live in Honolulu the thought of a major hurricane scares the heck out of me. My food and water supplie goals are for four people for a month.

Neither iodine or chlorine will deactivate Cryptosporidium in the 30-60 minutes recommended on the package. BUT if either chemical is left alone to treat the water for 6 hours, almost all the Cryptosporidium will be deactivated. You should try to filter out any solids, warm-up cold water, and most importantly, give it as much time to work as you possibly can tolerate:
