potable aquaWater Purification Tablets, Portable and Effective Water Purification Solution for Camping, Hiking, Emergencies, Natural Disasters and International Travel, Two 50ct Bottles, Blue

They are the tiniest tablets. There is cotton packing the top, which seemingly could be used as steril ER first aid. I wonder how many uses they could have in first aid, but bottle says only to use as directed. For the size, and the purpose, it makes grat EDC gear. Dehydration is your second greatest enemy next to hypothermia.

Just as advertised and I would buy from again.AAA

Work very well

I purchased them for my son for scouting and although he never had to use them .He has them if needed.He was in Scouting and had several hikes that were in wilderness and thought he could use them if needed.

These area great tablets to use for emergency use. Always start with the cleanest water you can of course - like running water, not still water. It's not going to clean bits of dirt and stuff from the water - it just kills the little baddies that can make you sick, You drink a bit of dirt you'll live. But just get some fast moving water, preferably like off a small waterfall, and you'll love it.
