Potable Aqua Chlorine Dioxide Water Purification Tablets - 20 Count

For several years I have been drinking reverse osmosis filtered water only, at home and at work. I carry two or three liters of it to work with me every day for that purpose. My tap water is lightly chlorinated and not fluoridated. The untreated tap water tastes good, and the RO filtered water tastes great. I got these tablets for use on trips but decided to test them first with RO filtered water to find out how they affect water taste and see if I have any adverse reaction to drinking it. My Results Tablets received on time and not even close to expiration date. Tablets are easy to use as directed and dissolve with fizzing action like Alka Seltzer in about four minutes. I followed directions and used one tablet per liter of RO water, using both glass bottles and stainless steel bottles. While tablets are dissolving a stream of bubbles rise from it and creates a mild distinctly chlorine odor. In the clear glass bottles used I could see the water was clear and white and colorless before treatment and clear and very slightly yellow/brown after treatment. Ten minutes after treatment the treated water tastes like highly chlorinated tap water. I have tasted worse in numerous municipalities here in USA. 36 hours later the taste is unchanged, highly chlorinated. In the past 36 hours I have drunk three of the four liters I treated and have had no noticeable physical consequences. The stainless steel bottles were not corroded or stained by the tablets. These tabs are very small and light and I look forward to carrying them with me on my next trip and being protected from pathogens in the water.

Really pleased with these in that there is less fear of a breaking hard plastic or glass bottle. As long as I carry these in a protected spot in my pack so the package doesn't get too smashed, I'm confident in this product. Just make sure you read the directions first. These will take 4 hours to work, so plan ahead of your water running out or prior to meals--and try to mark your drinking containers ahead of time with the amount that will match the formula liquid measurements best. This seems like a superior choice to even other choices in the "Potable Aqua" line, as far as what it is supposed to taste like afterwards as well. Just remember, chemicals won't be eliminated, and you should probably always use a coffee filter or bandana, etc to filter out any debris from standing water sources prior to putting in the tablets...if you are desperate and can't find CLEAR water from a stream or river to purify instead.

The only downside to this product is the 4 hour wait time. I got around this on a recent trek up Kilimanjaro and 2-1/2 weeks in Tanzania by buying iodine tablets that took a half hour (plus 30 min. additional if using the neutralizing tablets) and then using these overnight to purify the water in my Nalgenes. There is little aftertaste and it helped me conserve the iodine which I needed during the day. You will also need a knife or scissors to open these, so if you're camping make sure you bring a Swiss Army knife or something. Overall, a good product I will be using again on multi-day trips and visits to developing countries.

I am not sure what Chlorine Dioxide tabs are supposed to smell like, but these are SUPER pungent! I used two in a test run to see how water purification works, and boy was I surprised. I waited the 4 hour time period to allow the tablets to work, using the appropriate amount of water as directed, and when I opened the container that I had used, they reeked of bleach (chlorine in this instance). I am not sure The positive part of this review is that there was no aftertaste as the description promised. That is, if you can get past the pungent reek of chlorine. I do have to give an advisory about the fact that it was my first time using this product. I put a few in my bug-out-bag in case of need for them. I did enjoy the individual packaging though, this is what compelled me to purchase this product.

They package I received looks just like the picture and in it are a few tabs of the tablets in their sealed foil retail package. I cannot comment to their effectiveness but if they are what they say they are, and I have no reason to doubt they are, then they should work just fine to purify a questionable water supply in an emergency and temporary situation. Easy to store package, retail quality, fully sealed. I recomend if you cannot find these locally, since they are probably better priced locally at the pharmacy or something. But the convenience of front door delivery is something one usually pays for. Recommend.
