Beware, does not kill Cryptosporidium
"I keep a few of these tabs with me in the woods and truck to use in case of an emergency. They are really good at killing just about everything, so much so that I think a lot of people think it does kill everything. Just know that it does not kill Cryptosporidium, which is fairly common where most people hunt. If you use these in conjunction with a filter, they'll work great. Just know that if you use them alone, you're rolling the dice a bit. They also impart far less of a taste than the water purification tablets did in the past."
