Question: I've never tried any purification tablets before....can you taste them in the water?
Document: I have tried this with and without the neutralizing tablets, and I can say that I don't mind the taste. Plus, if you're really thirsty, and have already been waiting 1/2 an hour to purify your water, chance are you won't want to wait another 3 or so minutes to make it taste a tiny bit better. Buy the one with just the purification tablets, you'll save your self a few bucks.
These tablets work very well and if used properly there is NO bad taste. We have used these for water purification in the out back in Mongolia and have never had any problems. We also used them in India with very good results although the water had to be sieved to remove all the dead stuff floating in it after treatment. I would recommend that everyone keep these on hand even at home in the event of power outages and for camping etc.
My brother and I used these tablets on a backpacking trip in Michigan's upper peninsula. I didn't mind the taste, and I never got sick from using stream water and the tabs, so I assume they did their job. My brother thought the aftertaste was a bit strange, so it must be a personal preference type thing. Highly recommended.Pro tip: The purification step takes around 35 minutes while the after taste remover takes an additional 5-10 minutes. Plan accordingly.
Iodine tablets are great for emergency water purification when you are hiking because they are so small and almost zero weight. The down side is that iodine taste terrible.This kit contains additional taste neutralizing tablets that do a pretty good job of getting rid of the iodine taste.With the long 4 year expiration, these are handy to keep in the back pack for emergencies...
While I'm fairly confident I can get a fire going and boil water on extended camping adventures, it's a good idea to have a few water treatment options. Now, water purification has two stages to consider....bacteria and chemicals. We use these chlorine tablets to treat the bacteria, then add the included ascorbic acid (vitamin c) to remove the taste of the chlorine...and this water is very drinkable.
And so I turn to the inexpensive, time-honored tradition of iodine in water. A bad taste? Sure. And of course, some people are allergic, and this isn't an option. But I will never break my iodine tablets. My iodine tablets won't get clogged and require cleaning on the trail. And I can buy twenty or more packages of these for the price of some other options.And as to cryptosporidium, well, that truly IS rare.
I've used the purification tabs before in Boy Scouts and they left a bit of a funky flavor in our mouths. This kit worked fantastic. We were out on a 65 mile trek and was able to make 12 quarts of not only potable water, but tasty as well. No funky aftertaste. Very highly recommend
I bought this for the Southern CA &#34;big one&#34;, and keep it with my earthquake kit. So I've not used it and my hope is that I never do; but it appears good enough in the even our water system does need purifying.
I want to let buyers know that if you try to put a few tablets into an Altoids tin, they need to be protected from each other or they will crush together and fall apart. I had to wrap each tablet in cotton ball material before stuffing two of the purification tabs into a tiny ziplock bag; and it seemed that the plus tabs (to improve taste) had to be packaged the same way in a separate ziplock.
I've changed from using a water filter to this Potable Aqua solution with neutralizer. It's quicker and easier than a filter for backpacking, and the neutralizer tabs (vitamin C) are very effective at eliminating the off color and taste of the iodine.The tabs are more reliable than a water filter and lighter to carry, also.
Answer: yes
