Rated 3 out of 5 by from They don't work everywhere. I've used these backpacking in CA and most recently in Hawaii. No problems here in CA, but I caught Giarida in Hawaii despite using these tablets to treat our water. We followed the instructions as always, but as others have stated they just do not kill everything. I'd use them again, but only combined with another method such as a filter or Steripen, which I'd considered buying but cheaped out - now I'd gladly pay that price because Giardia is miserable, recurs, and the medicine to kill it makes you feel even worse.

Rated 5 out of 5 by from Portable, easy to use & no aftertaste I used these products while on a recent four day backpacking trip in Newfoundland. What I liked about them: 1.The containers weighed next to nothing. 2.The containers are colour coded & that made it a whole lot easier to remember which one to use. 3.There was zero Iodine taste after using the tablets and the water was clear coloured. The only issue for some people, particularly if you are only carrying one water bottle, is that you do have to wait 35 minutes in total for the water to be safe to drink. I had 2 water bottles so when I emptied one, I'd refill and add tablets immediately so I never had to wait.

Rated 5 out of 5 by from Awesome Stuff I've used these little guys as both a primary and secondary water purification source. They are ridiculously easy to use and ridiculously easy to pack, which is why I never go anywhere without them in my pack, my first aid kit, my car, etc. Generally I have used them the most when out backpacking and will often use the tablets instead of an actual filter since they are so much smaller and easier. The taste is the only downside. The treated water doesn't generally taste that great, but when I'm out backpacking or climbing I'm thirsty and some funky tasting water tastes just fine to me especially when I know it's clean.

Rated 3 out of 5 by from Does the job Used these on the John Muir Trail in Yosemite. They provided bacteria free water and the taste wasn't bad either. However, the iodine stains hydration reservoirs a brown color.

Rated 5 out of 5 by from Yummy Does exactly what it says. I didn't die and the water didn't taste like iodine so I consider that an A++++!

Rated 5 out of 5 by from A must have! Potable Aqua with PA+ Drinking Water Germicidal Tablets are a must have for any situation. These will come in handy on a long hike if you run out of water, and are over all just great to have handy especially in our world today with toxic chemicals leaching into or getting dumped into our water supply. These tablets also kill all bacteria and viruses in the water so you can be rest assured when out and about to aide in your hydration needs. I also noticed this product as a long expiration date on them which is good if you are planning on using them at a later date for an emergency situation. I haven't noticed any negative things from using this product and can only keep saying this is a must have if you are into camping, hiking or overall survival.

Rated 5 out of 5 by from Great for Travel! (Not just for camping) I use this product extensively while traveling to areas with unsafe drinking water. While most of those traveling will purchase water bottles, I found the tablets to be a great alternative to avoid wasting plastic bottles, avoid the worry of not having drinkable water, avoid many trips to the store to buy more bottles. I could simply fill up a jug, sterilize it with the PA products, neutralize it and have great drinking water in the bottles I brought.

Rated 3 out of 5 by from OK in the US These things are great in the US when you don't have to worry about too much. However, I am a frequent traveler to Central/South America and these things aren't enough. Unfortunately, something bigger and bulkier is needed out of the country [SteriPen is unreliable], but these are great in the US/Canada.

Will these tablets kill viruses?  Can they be used with chlorine tablets to eliminate cryptosporidium?

Asked by: Oldeguy
These tablets destroy viruses but are not absolutely effective against Cryptosporidium. We suggest Dioxide Tablets to kill all viruses and hardshell micro-organisms: https://www.rei.com/product/736898/potable-aqua-chlorine-dioxide-tablets-package-of-30
