This product works very well, the water has a very strong chlorine smell but it's safe to drink. I only used this for our drinking water and not for the cooking as we just boiled that water. I used some flavor mixes for the drinking water to get rid of the chlorine smell.

Must have for any hikers camper survivalist hunter gather. Weights nothing, but means everything. I always have my filtration water bottle, but when that filter is no longer usable for the rivers, these pills can continue the filter use an additional 450 fills by making the water a trusted source, so I have 2 filters, 2 of these & a frontier filtration straw (& my mess kit, for easy boiling). Recommend and will buy again.

I purchased this item because I hate the taste of the iodide tablets, which some people also may have an allergic reaction to. These taste better and are safer in regards to allergies. They are also more effective than most other options, short of filtering or boiling.

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.

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.

I have always kept an emergency kit, and while iodine tablets will kill of Most bad stuff, this is what you need to kill off Cryptosporidium..... iodine is Not rated for that. I have some of both.

After reading that Portable Aqua tablets don't kill the smallest viruses I read that these Chlorine Dioxide Tables do. You can Google it and see it is true. These are more pricey and take 4 hours to work so don't be in a hurry. The pills are individually packaged making them bulky and a bit of a hassle trying to get them out of the packaging. It's worth it if in a dire emergency I'll be glad I had them.

Don't waste your money on portable aqua tablets get these instead there are plenty of studies proving these work.

My preferred chemical for purification, but still use with a filter to avoid cysts. Decent choice when boiling isn't an option.

With your own quart size bottle, a Life Straw and this product you can have a quart of safe clean water per day for about twenty days. That's almost three weeks! Get more product for more water!

Just one plastic bottle that you bring back and recycle at home. Fill your bottle with "tap" water add a dose of this to it and wait four hours or just over night and voila! Safe water. You are hydrated and it works anywhere there's tap water.

Think of four hours this way: A safe batch of water in the morning for noon then make another batch for 4 P.M. A one gallon daily supplement of water per day.

A practical and light weight solution to a problem while traveling. Just one recycled plastic bottle too....

If you are building a go bag, you need to have at least 3 methods of purifying water: boiling, chemical, and filtering. These are a great augmentation to iodine pills. You can only use iodine for so long before your body (even those not allergic to it) starts to complain loudly to you. Some have criticized that these take 4 hours before you can drink the quart each tab cleans. Because it works on viruses, it takes more time. Place it in the container with the water overnight and the next day you're good to go. These are also safer and easier to transport than traditional bleach (pouder or liquid), for obvious reasons.
