Anyone who has ever had a waterborne disease can tell you that being sick like that is no picnic! There are many ways to prevent these illnesses from happening (i.e. boil the water, use filters, etc.), but the leanest and most effortless method to make water safe to drink is to drop a purification tablet into a bottle of the suspect water.

So, which tablet is best? Let’s take a look at two of the most common and popular options–Katadyn Micropur and Potable Aqua–and let you be the judge.

Shelf Life
If you’re stocking a cabin, cave, or BOB with water purification tablets, you certainly want to consider the lifespan of the product. The iodine tablets from Potable Aqua have a one-year shelf life. That’s pretty good, but the Micropur tablets have double the lifespan, lasting for two years or more.

A 30-count pack of Micropur tablets retails for $12.95, while the iodine tablets can be found in a bottle of 50 for $6. Potable Aqua definitely offers a greater value.

While these two products are using different chemicals, they both seem to be better than 99% effective against waterborne pathogens, which makes this category a draw.

Speed Of Disinfection
Potable Aqua is the clear winner in this round. The water is ready to drink 35 minutes after the treatment begins, versus 4 full hours for the Katadyn tablets.

Side Effects
The toxicity and flavor of iodine can be a little problematic, as they’re generally not a good choice for pregnant women or anyone with thyroid issues. The Katadyn product is chlorine based, most of which dissipates over the allotted 4 hour waiting period, so that product is widely tolerated and tastes much better.

The Wrap Up
The Katadyn Micropur tablets cost more and take longer to work, but they last longer on the shelf and taste okay. Potable Aqua’s iodine tablets are cheaper and work faster, but taste worse and don’t store as long. Plus, they could cause complications in certain people. So what’s your pick?
