Rated 5 out of 5 by from No taste problems This is a good chemical water treatment. It leaves minimal to no aftertaste and is lightweight. Also, it is cheaper than the Katadyn brand tablets, but offers the same performance. The four hour wait time is a bit long, but in many cases you can wait just 30 minutes, as the four hour wait is only for Cryptosporidia.

Rated 5 out of 5 by from Perfect Product While you may have to wait 30min (4hrs if your REALLY paranoid) it sure beats carrying a filter. These pills leave almost no after taste, the water tastes just like city tap water after treatment. Effective, cheap, lightweight - What more could you ask for!

Rated 4 out of 5 by from A No-Brainer Bottom line -- don't leave home without it. I've seen and experienced all sorts of troubles with so called bomb-proof water filters and the end result was usually one of two things: you're at the mercy of some rancid tasting iodine tabs you can pick up at wal mart for the spare change in your pocket, or you're forced to head home early. I bought a 20 pack to carry as a backup i actually wouldn't mind using if faced with filter troubles. They pack down small, don't hardly weigh a thing, and the package is suprisingly thin...there is no good reason you can say they're an inconvenience to you. The time it takes to be fully effective is the reason i won't give it a perfect score. It will kill all bacteria and parasites within 30 minutes, but up to 4 hours(!) is the manufacturer recommended period to ensure that giardia, cryptosporidium and other visures are dealt with. Iodine on the other hand has one major limitation... it is ineffective against crypto. Potable Aqua in a sense has become my insurance policy and has its regular place in my emergency and first aid kit. Most guys who use a chlorine dioxide based treatment will only wait the first 30 minutes before deeming the water safe. All of what makes untreated backcountry water questionable is killed off in that time, whereas the full treatment period is required for third world type of places. Pay as much attention as you do to keeping your water safe towards keeping your hands clean and sanitized and digestive tract illnesses are likely something you'll ever gain first hand knowledge of.

Rated 5 out of 5 by from Compact and light! I carried these on my backpacking trip last week and really appreciated their light weight and compact size. They can treat larger quantities of water at once than a UV pen and don't require tedious hand pumping. Even when I carry other purification methods, I pack these tabs as a backup because they are foolproof.

Questions & Answers

I'm going for a three week backpacking trip in Maine's wilderness this June. I see it says it treats 20 quarts, but is that per tablet or per pack? Thank you for your help!

Asked by: Denise
Actually, I think the REI employee is wrong - one tablet will treat only one quart of water. If you look on other websites, they very clearly state that it is 1 tablet/qt.
