Potable Aqua Chlorine Dioxide Water Purification Tablets - 30 Count

4 year shelf life, with 11 months left on it. Do not buy.

When going out, even for what you think is a day trip, taking a water purification method is critical. This is one of those items that you can take and never notice it's there, until you need it. When you need it, it will not fail you! That said, when packing for a trip this is always better complimented with some form of ceramic filter, or other filtering system (as is noted on the product page as well.) That is because the chlorine dioxide will kill anything harmful in the water, and your filter will ideally remove any particulate. The treated water has a minimal taste, which is even lessened or removed if filtered after treatment. Not to go too far into technique and practice; this will fit nicely in a small pouch (throw the instructions on too!) with water filter, and a bag for holding your water while you treat it. If you don't already having a bag only for dirty water, that folds small, is something you might want to add to your list! Coming back to the product! These are tried and true "Potable Aqua" has ben around my whole life, and are a trusted name brand for outdoor enthusiasts and those who find themselves in places with unreliable water filtration.

Only bought them for putting stay in case of emergency in a storm n havnt needed them yet there just a piece of mind item or insurance policy at the moment

I noticed that the chemical in this product (Chlorine Dioxide) is the same as the main ingredient in very spendy dog-water additive intended to address bad breath, so I decided to try this for my old dog instead. The first day, I just used one tablet to treat one quart of tap water. The chemical smell was very strong, and a quart is not enough water for a day. The next day, I decided to boil two quarts of filtered water, let it cool, add one tablet and present it after half an hour. I figured, that way there would surely still be active, residual chemical to help with the bad breath problem. This seems to be the way to go. The chemical smell is not too strong. My dog drinks the water readily, and my cat prefers it to her water dish. The difference in my old dog's breath was noticeable within 24 hours, and her problem with bowel incontinence has also improved. UPDATE: Over time, I believe using the product this way may have interfered with my dog's beneficial gut fauna. Her incontinence problem got much worse. I stopped using this product for a couple of days, and the situation improved. Based on that experience, I would say it's OK to use this as I have for a week or two at a time, but not full time and not without breaks. She has recovered now with the addition of some probiotics to her diet, and we have changed to parsley in the food and a bit of fresh ginger in the water for bad breath. Not quite as effective, but much better for her.

Just what I was looking for, a water purification tablet that actually makes water safe to drink. Hope I never need them.
